This channel can become the next JerryRigEverything. Much appreciate your videos! Good job.
Thank you
@zamzZ Thank you
@@PBKreviews hey does front camera has OIS
It's so awesome that you answer questions from previous videos in you're new ones! definitely one of the best teardown channels!
:) thanks, I try to answer as many comments as I can.
Hi from Australia, thx for the vid. Great stuff.
Two quick questions. I just started a new job which is very very dusty. Now my speaker is muffling with sketchy quality.
I'm thinking of opening up and attempting to blow free any dust hopefully improving sound quality. What are you thoughts?
Also, I may have missed it but I'm guessing any time phone is pry open adhesive must be replaced? Where can I get my hands on some? Tried of your links but not working.
Thanks again.
Hi, usually the filters over the openings where the sound comes out are the ones which get clogged and cause noise issues. You can try using a tooth brush to brush them off, and if its metal shavings which have been attracted to the speaker, you can use a small magnet to try and remove them off the filters. But if its the top speaker, you would need to take it apart to remove the speaker and brush off the filter or replace the speaker etc. And yes you would need replacement adhesive to re apply the back plate. Here is a link: amzn.to/3Y3bfKr
Excellent video!! You do a great job with your cadence, volume, and explaining everything along the way! I replaced my S21+ battery without the aid of your video, but had problems with the screen afterward, Your video quickly helped me identify the connectors I needed to look at. Thanks again!
Great video! I'm Goin to replace my back cover ( cracked over the camera lens ) If I install a new one would I need new adhesive? If so what kind do you recommend. Or is the adhesive still on the phone itself?
Hi, thanks. Usually the back cover replacements come with pre installed adhesive. If not, you would need new adhesive strip to install the back. Here is a link to one if you need : amzn.to/3x6tpN2
I know this is a late reply but all of the back replacements I got off Amazon for the S21 plus have always ended up with gaps inbetween the panel and the frame so instead of wasting money I'd just buy an adhesive strip instead@@PBKreviews
I know that when you insert the sim tool through the hole of the microphone it will not be damaged, but could you explain if there is something in the hole and also what it hits at the end when you insert the tool, clearly something feels that there is inside of the hole.
Does it damages the waterproofing of microphone?
Muchas gracias por el video, mi s21 plus se cayo y crei que ya habia muerto, por fortuna eran unos tirnillos y flexores que se soltaron, gracias a tu video pude hacer todo correctamente y despues de una semana sin telefono lo tengo devuelta (aunque desgraciadamente ya compre otro y ya viene en camino sin poder cancelarlo) ty.
Sir...you really jenious...you are a brave man... Love from #Bangladesh... Sir...i'm using Samsung Galaxy M51...
I know this is an older video, but I have a question. There is a black sticker where the wireless charging coil is connected to the speaker assembly. Is that black sticker just adhesive to hold it in place?
YES!
:)
Im using this phone . Thank you 😊
You're welcome
S21 +, That's what I care about,thanks alot!
You're welcome
@PBKreviews, is the S21 Plus' back held in place by a glue? Does it require a glue to be help in place when assembled?
yes it's held in place with adhesive strip. check my video I did on how to replace smartphone adhesive for a better understanding
Great video, just need some advice, I have a samsung s21 + which has developed a black screen, the touchscreen still works and sound, possible loose connection inside? Or a software issue? Thanks
Thanks. It could be a loose connector or sometimes from drops, the screens get a hairline crack somewhere that is hard to see or not visible which prevents the screen from displaying anything. It could also be water damage if any corrosion built up around the screen connector or motherboard or just a defective screen. Usually not a software issue.
Great video, very informative.
Could you please clarify if the microphone setup is exactly the same as the regular S21? I’m especially concerned with that microphone under the flash - I have bought two different regular S21 and on both of them the sound quality when recording video and mainly in video calls using WhatsApp for example was really awful especially when filming for example my kid from a small distance, persons in the other end of the call cannot distinguish what he says. I’m assuming this is because there is no microphone hole on the back…
Well the plus version have the same issue?
Thanks for any help on this matter.
Thanks and yes it is the same as the S21. So changing from the S21 to S21+ would not make a difference as far as the microphone layout/setup.
Do you know what size the triwing screws are? I need to get a bit.
I wanted to replace the side frame of my s21 plus. Since it would require the back to be opened, will it damage my IP68 rating?
Thank you for the great video,
I'm guessing the sim pin from samsung box does not reach the microphone if probed into the wrong hole for top and bottom?
You're welcome. The mic sits above the hole so the pin wont touch it.
Would you damage the water proof seal if the pin was put into the hole of the microphone?
Good video as usual 👌
Thanks!
Best teardown channel right here!
Thanks!
Is it just me or is it a better vibration motor on the S21+ than on the S21?
ya has a newer linear style haptic feedback motor. s21 has the older style cylindrical motor
Nice job. Hard replacement battery do that series trash. Have y reccomend some new phone with good battery replacement?
Thanks! Usually I find the Xiaomi phone batteries to be much easier to pry off and replace with the battery pouch style pull tabs they use.
you're the best! ❤️🔥
Thank you for this. I love seeing the insides of electronics
You're welcome!
Can you do a video where you flash dual sim software on a single sim phone and check if it works?
I'm not too familiar with flashing software and unlocking bootloaders etc. First someone would need to find a way to unlock the bootloader if I am not mistaken before software can be altered or flashed.
@@PBKreviews I might be wrong, but as far as I know if you flash OEM software with Odin the bootloader does not need to be unlocked.
@@heever91 Oh, not too sure, but I'm almost positive with software from a dual supported enabled model flashed onto the phone, it will read dual sims. Or if the software is rooted/bootloader unlocked and the second sim reader pins are enabled from the software. It was the same way with other phones where it required the software from a dual sim version to be flashed onto the phone when you tried making use of the dual sim slot from a phone which originally had the dual sim but was disabled.
@@PBKreviews
i purchased a s21+ from amazon to dubai it has open u1 firmware but only 1 sim card i purchased a dual sim card tray online will inserting dual sim card tray and flashing new firmware make my mobile dual sim. can u guide me which firmware to flash...
@@mrfantasticindian1593 you would need to find FW that works for snapdragon and uses dual sim. The US based all single.
Accidentally I inserted SIM ejector tool inside the S21 Ultra microphone hole. I also applied some force in an effort to push out the tray. Although, the phone is working OK so far. Did I break something inside? Microphone / Mesh / Water protection. Kindly clear my doubts.
Hi, you should be fine. Both the mic and the filter sit above the hole.
@@PBKreviews thanks for the reply
@@ferrydaddy did you test it and is you phone still water proof? I made the same mistake.
@@johanstoltz5145 4 months already. The microphone is working perfectly alright. I don't know about the damage to the water proofing.
@@johanstoltz5145 is your phone working ok?
Hi just asking. If i were to replace th glass cover at the back, does still have the water resistant that it originally had
If you buy one that comes with the original pre cut adhesive attached to it, then yea. Or you may need to purchase the original pre cut adhesive for it if it does not come with it. You can buy the original back glass with original pre cut adhesive on it at this website www.mobiledefenders.com/samsung-repair-parts/galaxy-s-series/galaxy-s21-5g-62.html
In top right corner there 4screws holding what flexible and what it use??
it's an antenna flex cable.
I am a huge fan of ur videos... 😃 btw where are you from?
Thanks! CA USA.
thanks bro. this really helped me
No problem 👍
I have a question, I have an S21+ and the camera housing on the back has some scuff marks. Can only the back be replaced or does the front and back have to be replaced? I was told by a repair shop that both the front and back need to be replaced and it would cost me around $300
The back alone can be replaced. You can find the original replacement parts on mobiledefenders.com
Other than charging, what other purpose does secondary board do?
Has antenna contacts on it as well.
Is it normal for the graphite thing near the cameras to heat up a little? even if the phone is not being used/stand by mode?
yea, sometimes running apps in the back ground or antenna being in use can cause it to heat up a bit.
Which parts do we need to remove to replace the power button ?
Remove the back plate, and screws on the top motherboard covers and remove those so you can disconnect the power button flex, and pull the power button flex with metal bracket from inside the frame slot out.
Does the factory screen protector need to come off in order to open up S21 for service?
nope, does not need to come off.
Hello. How to replace front camera? I get dust on the front camera. And the interlocutor hears an echo during the conversation. What could be causing the echo? Does the sound from the speaker reach the microphone from above or below?
there is a secondary mic on top you can see the hole for it on the frame. Also the camera is held in place with glue, so i doubt its from the back side but more likely from the front. the screen adhesive has probably gone bad and is lifting up, allowing dust under the glass.
Excellent video my bro. I'd like to know if i can put the sub board of a SM-G996B in a SM-996N to convert the single sim one into a dual sim device
Thanks. Even if you replace it with a dual sim reader sub board, it wont read a second sim since the firmware on the phone has it disabled. You would also need to flash the firmware to one that is from a model that does support dual sim so it has the feature unlocked. But you may also run into signal issues since the sub boards have different antenna contacts and may not be fully compatible with network providers in different regions etc.
@@PBKreviews Ooooh, I get it bro. Thank you for taking the time to answer. You 🐐
So apart from 1 sim tray, single sim phone does support dual sim and it's only software locked?
yup
Boa noite.
Como eu faço para trocar o botão de volume para colocar outro?
Como faço para acessar?
O que eu tenho que desmontar para ter acesso ao botão de volume?
Grato.Do Brasil.
Depends on if you are replacing just the outside button or the flex cable internally with the clicker on it. If just the button, it can be pulled out from the frame. If the flex cable, it requires on this model to pry the screen off to gain access to it. So you would need to disassemble the phone and pry the screen off as well.
Did you notice any water damage stickers on the inside? I thought I saw one by the lower speaker.
Ya there is that one rectangle white sticker on the frame when you remove the bottom sub board.
Good video thanks
Thank you, and you're welcome
Hey can you display all the parts together side by side at the end of your videos ?
Will look into doing it
Hey, that's an awesome and very informative video! Well done.
Maybe you could put me out of my misery hahaha I'm concerned in reason of a mal practice by me when I bought my galaxy s21, was very excited and even tho it was a light pressure I did insert the sim tool at the bottom mic hole. I did some research but nothing with a solid confirm that this pressure would or wouldn't damage the microphone, or even affect the IP68 water resistency of the phone. As I mentioned was a light pressure, but It happened anyways. The microphone sounds clean and unaffected, and it is something very unusual to happen, but yeah.. I was the genius to do it. haha
Video is really good, hello sir
My samsung s21 plus display is showing blank so I want to repair at home
But not sure if it's really a display issue or if you have any idea let me know
How I can check exactly issue
so I can repair it.
Thanks. Only way to know is buy testing with a working screen to see if its the screen or not.
@@PBKreviews thanks for your reply, so can I test any screen of Samsung model, as I have one more samsung mobile so I was thinking only testing purpose use that display is that work galaxy j6+
And also I want to diagnostic hardware and software so how I can do that to find out other problems please help on that
Will the s21 & s21 plus motherboards fit in each others midframe?
Hi, no they won't.
@@PBKreviews ty
does the international version support dual frequency gps? does it read L1 and L5?
I'm not sure
What type of adhesive is using for back cover ?
Its a water resistant double layer adhesive. Not sure the exact type or what its called.
@@PBKreviews Thank you,just in case is needed to use.
If i remove the back cover and glue it again,i want to be perfect,like the same before.
@@dani25801 no problem. Usually a month or two after, replacement pre cut back adhesives become available online.
Thank you
you're welcome
The dreaded Android black screen I got vibraition can u help
Is that back part plastic material or glass??
It's a type of glasstic material. More shatter resistant. But ya is glass on the S21+ and ultra, but the s21 is plastic.
Bought a used S21 5g and my rear camera is just 1 piece of glass over the lenses is this just a after market protector?
It's possible someone put a camera protector over it.
Where can I get a processor replaced on a s21 plus
I love how every video shows the GLASS back plate coming off nice an easy when in reality you're gonna send chips of glass flying everywhere. WEAR EYE PROTECTION!
If you have glass flying everywhere you did it wrong
S21 and s21+ are not glass backed. It's a plastic.
Can you remove the aluminum 3 camera housing cover WITHOUT removing the entire back of the camera?
Yeah its held on with adhesive so you should be able to heat that outer portion and pry it off, but be careful since there is an underlying thin metal frame under that as well which is tucked underneath the back plate/battery door. So you would want to just pry off the top layer metal frame. Also the circle class covers over each camera are held in place with adhesive too and those can be individually replaced as well. Worst case if you damage anything on the back cover attempting it, replacements aren't too expensive. Here is a link for original replacements, and you can find cheaper aftermarket ones on ebay as well. www.mobiledefenders.com/samsung-repair-parts/galaxy-s-series/galaxy-s21-5g-76.html
I need a bottom speaker ! Mine is nusted and i cant find a replacement one. Neither can any phone repair shops near me. Any suggestions?
Hi, not sure. I just checked and couldn't locate one online either.
@@PBKreviews every phone repair in my town says they cant find any, because the phone is still new, its only been out for about 5 months
What chip in the phone causes the phone to just black out and stop working
If you put the mainboard flex cable upside down how much damage can that cause?
I think you should be fine, just flip it around and install it correctly.
So if there is no 5 g antenna means is not 5g phone right?
No, just means it does not have mmWave 5G but still has sub 6Ghz 5G.
Que tal la calidad de los componentes?
They are good
Accidentally poked the bottom microphone hole will it damage the ip68?
Hi, no you should be fine.
@@PBKreviews thanks a lot
@@dennisbanol7704 you're welcome
Is frame made of steel or aluminum?
The midframe is a type of aluminum alloy.
I have a tiny hair stuck on my middle camera lense I don't wanna break it s21 plus so thank you for the info
you're welcome
Hallo Sir, my S21+ G5 256 start power off didn't light up in red. What is here the problem. (How can I solve it)
Another great teardown. Thank you for your hardwork.
Thank you and you're welcome
How about the Water Resistant? 🙏
It has water resistant features like the water resistant adhesive on the back plate as well as the rubber gaskets on the openings for the speaker/mic etc.
Hey, why there's a small sound in the top part of my S21+ when I shake it, like a shaker with 1 bead inside, is it just a screw that come off or something?
Hi, its just the camera assembly its normal.
@PBKreviews so there's nothing I should fix, right?
@@vikerofficial2420 yes correct, nothing needs to be fixed.
@@PBKreviews Thank you very much
@@vikerofficial2420 you're welcome

I used arctic MX-4 thermal paste now its cooler than my fridge
Nice
Hello dear family, I hope you're doing well 💜 so I have a question 😊 just to know where can I buy a motherboard Samsung Galaxy S21+ 5G ??? I from Russia 🇷🇺
You're best bet would be ebay or other online markets which people might have taken the phones apart and selling the motherboard by itself. If not you would need to find a phone with a broken screen or other issue to take the working motherboard from.
Cool
How do we know if the phone sold in our country comes with Dual Sim? Samsung makes it so confusing and difficult to know this year
Yea it's not too clear on their website, but if you can get to some specifications page on their site, it should list Sim 1 and Sim 2 in network section or mention dual sim. Also It should mention it in the highlights section of the phone. Here is what it looks like : ibb.co/vzjv8c6 and that's the one from UAE samsung site ( www.samsung.com/ae/smartphones/galaxy-s21-ultra-5g/ )
Can someone help i replaced the screen but ever since its not picking up my sim card 😢I have tried other sim cards to no avail is one of the flex cables something to do with antenna
Could be a loose cable. Make sure they are all in place properly.
Which cable the green antenna flex is broken but thought this only affected the WiFi signal ?
What's the battery voltage
3.88
Does anyone else have the small rattling sound when shaking this phone? It sounds like something is loose inside.
Hi, its normal, its the camera module/assembly.
Backdoor Glass or metal ..??
Gorilla Glass
My phone keeps turning on whenever I try to remove the cover
not sure what you mean
My ultrawide camera lens cracked a few days ago, so I just wanted to know if my phone will still have the water resistance after I get my camera lens replaced.
Hi, depends on how it is replaced. If you replace it with an original oem replacement with original pre cut adhesive then yes it should retain the water resistance. You can also order the complete original oem back plate/ back glass with the pre installed pre cut adhesive ( www.mobiledefenders.com/samsung-repair-parts/galaxy-s-series/galaxy-s21-5g-81.html ) and pry off your old back plate and apply the new one, press firmly down on all the sides for 30 seconds to adhere the back onto the phone and that should do it.
@@PBKreviews okay, I'm getting it replaced in the samsung service centre so do you think they will use the original parts?
@@Johnsolo_23 yea they will use original parts
@@PBKreviews oh okay, thank you so much for replying. I was just asking because I was worried that they won't use the original parts for my phone.
@@Johnsolo_23 If its a Samsung service center, they only use original parts and also test to ensure correct seal for water resistance. Only mom n pop shops or other places that are not authorized by samsung may use aftermarket parts or not guarantee a water resistant seal. You're welcome :)
Is it me or the back of the phone feels and sound like a plastic? Im concerned cuz I just bought s21+ and there is no way it is glass comparing to my s7. Keep it up
Its glastic, its a type of break away glass type material. But not plastic like the S21 back. Thanks
s21+ back cover is gorilla glass victus. dont believe? try hit the back cover with hammer they will crack like a glass
Where is the memory?
does the phone have cooler?
has 3D graphite layer which transfers heat. This is what has replaced copper vapor chamber, it lasts longer than copper vapor chambers and does just as well.
@@PBKreviews does it transfer the heat much better than the vapor chamber
Does front camera has OIS
nope
@@PBKreviews For S21ultra as well
Hello
i purchased a s21+ from amazon to dubai it has open u1 firmware but only 1 sim card i purchased a dual sim card tray online will inserting dual sim card tray and flashing new firmware make my mobile dual sim. can u guide me which firmware to flash...
dual sim try and flashing a firmware which has dual sim enabled would most likely make it work for you. But not sure which firmware you would need or where to get it from. You would need to know which region or carrier firmware comes with dual sim. I believe the UAE version has dual sim but again not sure where to get the firmware.
@@PBKreviews my phone model no is SM-G996U1 and uae model is SM-G996B,so won't flashing a different model brick my phone is there any risk involved since I paid 700 dollars for this phone

So the batery still li-ion?? I thought S21's battery were li-po
Ya its Li-ion on these. Its possible different regions may have different battery types depending on suppliers etc but most likely most if not all will be the same.
@@PBKreviews thank u!!
@@matheuspcsa You're welcome

Dude there's like dust in between the glass and aluminum of the cameras. On mine
Its possible the adhesive strip has lifted up allowing dust to get in. You can always order a new backplate with pre installed adhesive strip to replace and solve the problem. Here is a link : amzn.to/3xJlLZk
@@PBKreviews nah its nothing. Between the camera glass and bump just a bit of dirt gets in. If I ever see dust in the cam I'll just contact warranty probably. Thanks for trying to help though.

No expandable storage... 😔
yep unfortunately
for what on earth you need more than 256 gigs of storage on a phone? (and you can get onedrive or some cloud storage aswell so i really dont see the point in expandable storage)
@@kookaburra574 I need it for data redundancy. I don't want to use the cloud. And you won't loose all your data in case your phone dies... It's also more affordable.

for cell signal
Iam watching this video with samsung a52
nice
i did everything and for sure there was water in it , i dryed it out and my cell phone still wont power on or charge
Did you brush off the corrosion on the connectors and chips? also its possible the battery, display or other parts may have shorted or gone bad and you would need to try replacements with each to see where the problem lies. With water damage it's always complex. If its the board that has issues, then you're out of luck.
