your videos are so on point.. no extra talking, no stupid ads... hope you hit million soon bruv...
Thanks! 😀
hi! i was waiting for this video since the phone came out, and you are the first! New sub, keep the good work up
Thanks! Will do :)
I recently got this phone. I always like to see what's inside but I didn't want to void my warranty.
Thanks for this!!
You're welcome!
Is it still good ?
@Omar Darwish hell yeah it is.
@@SuperBoop just got the S22 waiting for delivery super excited
The best places for heat to escape from the device are the side edges. If the heat is transferred to the aluminum frame around the device, it would cool down quickly and optimally.
PROFESIONAL WORK MAN THANKS
What kind of adhesive should I use for the back cover?
Hei. I really want to know if green line issue on the screen can be fixed by replacing the flex with new one. Please answer
Hey my friend I just watched your video it was awesome and super fast just had a few questions I just got a s21 fe and I need to replace the screen where would be the best place to get the replacement and tools need can you send me the links if you have a moment. Thanks
I really would like to know, where the wifi "connector" is, because i think its loose in my device :/
Is the vapour chamber big compared to the new s23?
Hi i wanted to know if there is some clicking noise when u press the back pannel near the camera bump in s21 fe
Please help me out here!!
PBK, i have EU s21 FE , i do not have ANTENNA at left battery. Where it can be located please ?
What is the battery capacity written on battery?
02:24
What is the big "white/silver" square bit on the top right?
The chip? I think it's the Bluetooth/wifi module
Sir I applied the stickers on my S21 FE and tried to remove it after 4 months. While removing the adhesive of the sticker was so strong that the back panel kind of came a little bit because of it from the middle egdes of the phone. Now they rest perfectly well on the phone but i have the concern that. Has that void my water resistance of the phone??
Bro I have galaxy a72
The flash light of the camera is malfunctioning. It works for few seconds and then get dim. Shop keepers are not giving any reliable solution. Can you help on the issue?
Any idea what the white plastic parts are for on the sides. Two at the bottom and one on each side?
Antenna
Hi sir hello from Sénégal... are the camera outside lenses plastic or real glass please
Hi, you do a great job. Tell me if you discovered a dedicated DAC in all these smartphones? Thank you.
Thank you! I'm not too familiar with the audio side and I'm not able to give a positive answer on that, but I would assume the phones like the Xiaomi 12 pro would have a dedicated DAC and better amp compared to most other phones.
Hi, can you speak greenscren issue in lcd samsung s21 fe after update software
Compared to the S20 FE, the S21 FE is 4mm shorter and 0.5mm thinner. Looking at your teardown, I can see the 4mm comes from a smaller bottom speaker, and the 0.5mm comes from a thinner back cover.
👍
Really missing that low end my lg v20 had. Explains it.
no its because its 19.5:9 ratio compared to 20:9 on s20 fee
@@IcyJay30 S21 FE, like S20 FE, is 20:9.
@@xxxxxls lol, don't go by random websites, s21fe have 2340×1080 resolution Nd s20fe have 2400×1080, height reduction is possible when screen height reduced as well,
Also s21fe have 103cm² screen area (wide) and s20 fe have 101cm² (narrow)
One best channel to learned smartphone go ahead bro 😃
Thanks! :)
Are S20 FE 5g 12 mp rear camera interchangeable with s21 fe 5g?
Hello can I cut the wireless charging from the the other part I want my battery to be visible as I have a see through panel??
Hi, you don't need to cut it off, you can peel the graphite pad/film from the plastic cover as well as gently peel off the back of the connector for the wireless charging flex from the other side of the plastic and separate it from the motherboard plastic cover. But short answer yes you can remove the wireless charging coil/graphite pad.
Hello bro, my s21fe has the glass only damage and nothing happened to the main display even the fingerprint is also working, so the service centre is asking to change whole display, and charging 13k
So is it possible to change the upper glass only
Great video. Thank you so much. ❤️
However, sir what is that thing just adjacent to the bottom most rare camera lens? That site actually happens to be the source of a sticky sound when the back panel is pressed in and around that area, in many units of this model including mine. Kindly consider answering. 🙏🏽
Thanks. I'm not sure what you're referring to, but if you can screen shot it and circle it and email me the picture to pbkreviews@gmail.com, I will reply back with an answer.
Umm i had a question sir, i recently bought this phone and dropped the box, in which it was inside, it slipped out of the box when the box slipped out of my hand
and hit the floor on the bottom left corner (there's a little dent on the metal rail, the paint got chipped a little) everything seems to be working fine.
Do you think this could have damaged anything internally in the long run? Also the battery can swell from an impact?
Don't worry much, it sounds like minor incident, plus it won't affect battery
You're good!
my backplate has gotten loose after i left it for screen rapair and I think some dirt got in there and now the phone shuts off if i shake it then i clamp on it for a bit and it turns on again, so i just have it on a table all the time so it doesnt turn off. i think im gonna try to remove the graphite film and try to blow some dirt out of it if thats the problem but have u heard of this issue before maybe u know wut it is?
Hmm not sure. Can be water damage, loose connections or something else. You can try taking it apart and using a small brush like a tooth brush to brush off any corrosion if there is some from water damage or clean out the phone and make sure all the cables are connected and the main board is seated and everything is screwed in place. You can also order new adhesive to replace the one on your back cover or the entire back cover with adhesive pre installed from this website: www.mobilesentrix.com
just bought this phone. Samsung really does make easily repairable phones. unlike apple. I replaced my s10 battery with ease a few months ago. and now with this phone i have peace of mind that i can DIY in a few years time when needed.
Same, I actually got it as gift. I have an iPhone 11 Pro Max and while it feels more premium it weights like a brick and the notch is annoying, the iPhone 15 comes with the circular notch which looks better but while I can afford it, I'll rather spend that money on something else..
The side buttons of the S21 FE are related to power and volume. Is it made of plastic or metal?
Metal
You are awesome bro keep it up as I told uh earlier 🤗🤗🤗 gud wishes ❤️ god bless uh ❤️
Thank you!
I really like this teardown. Can you please confirm if this phone has a cooling system for heat dissipation?
Thanks. It has 3D Graphite which transfers the heat instead of a copper vapor chamber. It works just as well as a vapor chamber.
Очень интересно. Спасибо! 👍
Thanks and you're welcome! :)
Great details 👍
May i know where is the chipset location ?
If i accidentally insert sim ejector tool in microphone hole will the microphone or the waterproofing be damaged in this particular device. Please reply
No it wont be damaged.
Hi, thank you for great video, as I am using s22+ but it is a bit heavy and planning to change s21fe with promotion prize,would you mind telling me what is the texture of frame? plastic or alumminim? I know the back cover is made of plastic,but don't know the frame
Aluminium
Hi :) I wanted to ask if you know, where the power management ic (PMIC) is located?
I was smashing my S21 FE on the floor and now it doesnt turn on any more.
Opened the device, made sure everything is plugged in but still nothing.
Windows doesnt even recognize the smartphone in device management,
when connected.
I would be really happy, if you could help me.
I've already ordered a new phone, but there are many videos of my kids on the device,
unfortunately i've decided 6 years ago to disable cloude saving DCIM.
Thanks!
Hi. Not sure where the PMIC is. It might be a bad display also. Sometimes when the display isn't working, the phone doesn't power on either but again its just a possibility. Maybe even the battery went bad who knows, but yep aside from those I would lean toward the main board. You would probably need to find some specialty shop that does phone soldering who would have a better understanding of getting the PMIC or any other controller part on the board repaired.
@@PBKreviews the battery did went bad, but i've connected another compatible samsung battery with 3.88V and it still didnt power on. No vibration, no sound, nothing :(
@@adriankazmierski8541 You possibly couldve killed the motherboard
After two years of usage, the adhesive of the back cover seems to be coming off, I use the phone inside a case, so should I get the adhesive reapplied to my phone, or it's not an issue?
u shoud reapply the adhesive.
thanks! my device had fallen on the floor and charging was very slow, I managed to open it and one of the flat cables was a little loose. Now everything is working fine!
Glad I could help
Does a scratch on the lens glass impair photo quality?
I'm no cellphone technicians nor am I planning to open up my phone but these videos are really cool man
👍
@@PBKreviews Hello, I accidentally inserted the SIM card tool into the microphone hole, I am afraid of something happening, what could be the harm if I accidentally insert it?
No worry, the microphone assembly is mounded above the hole with a grill inbetween.
is there no cooling system in this phone?
Great video!
Thank you!
Hello, id like to ask i poked the top microphone accidentally with the sim card ejector. Is the microphone damaged because of that? Also is the waterproofing affected by that also? Thank you and have a nice day!
Hi, both the mic and filter are seated above the hole so they wont be damaged :)
@@PBKreviews thank you sir, you just saved me from a lot of stress. I really appreciate it :) Content is sooo underrated hope you hit 100k very soon :)
@@peterpaulrecabo3941 Thanks! :)
Hey I accidentally put my sim ejector tool in the microphone slot. Does it get damaged pls reply I'm worried 😥
no you will be fine, both the mic and filter are seated above the hole so would not get damaged.
Como abrió sin agregarle calor?😮
I have inserted sim ejector by in mic hole by mistake does that does any damage?
No you will be fine.
Nice video thanks! My newly purchased s21 fe has a slight gap between the back plate and main frame around the camera bump... Should I be worried about anything regarding ip68 protection? It's really small tho... only a thin piece of paper can be slid in!
Thanks. Hmm not sure, as long as your not seeing any dust or moisture getting inside the camera lens area then I wouldn't be worried.
Same issue, here in my country samsung is not even claiming that they are saying that your set is opened and warranty doesn't cover it. F**k samsung.
Bro l, I just got it recently and I have the same hap near the camera bump. I don't know if it's anything serious. It's only been 3 days I bought this phone.
Even when i was checking my phone near camera module adhesive is weak and there is gap there and also gap is near theupper mic
Ill not dare to dip in water now
@@AjayPatil-fj5tu sold the crap and bought an iPhone 13 last year… never been happier
is it possible to put a larger vapor chamber for this unit? it heats a lot
It would require modifying the midframe to allow a larger vapor chamber to fit.
what can i do to cool my exynos variant as it heats a lot
Lol, yeah, it gets very hot fast
Found a way ?
Molto bello e pulito dentro, come sempre. Esteticamente sembra un s21, comunque bel telefono.
👍
which atenna uses the 4g? and which one is 5g or are they both combo for 4g/5g?
Not sure exactly which is for 4G, but aside from the mmWave 5G antenna (which are the mid left of the frame and the one to the right of the motherboard by the frame) the sub 6 Ghz 5G antenna as well as the 4G ones are mostly the ones built into the frame where the motherboard and sub board contacts touch, as well as running through the sub board and motherboard etc.
You should try to add other stuff also on this channel...you are underrated. You got the potential but you are just holding up. You can easily get at least 2 lakh subs if you put more effort other than a professional teardown video
I do a different type of video here and there on different stuff but those don't seem to do well. Most of the people are just interested in the teardowns for the most part from me but I will keep doing other stuff every now and then as well. :)
Is the wifi antenna embedded in the speaker assembly?
I'm not too sure, usually they have it somewhere on the top corner of the phone.
Hey brother, i accidentally insert sim removing tool to mic hole..is it damage anything? pls help me
up to this
I couldn't tell up close, but I accidentally put my sim card tool in the microphone hole. Did doing this damage the microphone or the waterproofing?
Same question here
Don't worry everything will be fine
Good video brother 💡🤴🏻🙌🏻💯
Thank you! :)
Wow, very repairable! I am sold
👍
Yesterday by mistake i inserted sim ejecter tool in microphone hole without knowing. Microphone works properly but does it compromised IP68 rating? Please Reply
You can't damage microphone in that way, it has a Г-form
Please reply ,. I accidentally inserted sim ejector tool in microphone hole in s21 fe 5g.. Will it impact something like waterproofing
Hi, no you will be fine. The filter and mic are seated above the hole.
@@PBKreviews thank you for clearing my query
You are really quick. Wow..
👍😀
A piece of dirt/lint or whatever from outside fell into my earpiece when trying to get it out. Is this really bad? Should I get the phone serviced?
No you should be fine, the speaker itself has a filter over it as well.
@@PBKreviews nice! On a second note, do you know how hard the filter/grill and components of the earpiece are glued or set to the phone? Just to know how careful I have to be If I ever need to clean something without disassembling
This is not a Verizon one?
Thanks!
Welcome!
Found this video after being a dumbass and poking my sim remover into the microphone hole, I swear I felt something push in, but it's not very clear in the video what that could be, do you have any Idea?
Hi, you should be fine. Both the filter/gasket and mic are seated above the hole.
Accidentally I insert pin upper microphone on my s21fe. is it damage water resistent and microphone? Im worried about that.
No you will be fine. Both are seated above the hole and will not be damaged.
Thank you brother❤
Are the Exynos and Snapdragon version have same at cooling system?
I think yes
Can the phone get damaged if inserting the sim tray pin on the mic hole by error?
Yes
Great video
Thanks!
رائع جدا أحسنت
gotta love those coppers moving the heat from the cpu to the lithium batt :))) lithium loves heat
Haha
Copper is the third highest ranked element in regards to thermal conductivity. Only surpassed, by silver and diamond. Your contemptuous sardonicism was keen. It's not like one holds It, on their side head hole or nothing.
@@duhbestest1334 duude , we were talking about heating the battery...wth
haha. almost all newest phone have copper plate under the battery. even gaming phone 😂
@@rixyrohaizie and you think it`s great
Do s21 fe good in 2023
Too simple cooling system for SD888. My S20 FE already heats very fast with SD865.
Ya, I expected a bit more.
Me with exynoss 2100😂. Its burning.
Bisakah buatkan pendinginan yang lebih baik untuk smartphone ini?
Thank you for sharing! Do you know where the storage is located?
I want to destroy my data (Physically) before sending the phone for recycling (repairing costs way more than the value of the phone today)
It's one of the black large square chips located underneath the covered shields on the main board.
@@PBKreviews Thanks!
I have the S20FE. I can confirm that S20FE and S21FE have the exact same camera system
👍 yup didn't pay attention to that until you mentioned it.
Already own the s20fe, the only thing i would change on this phone is the front face camera.
@@fodaogamer1 👍
This dude need more subscription
yup :)
I have this phone, but was just told by Samsung advisers that it has a bad battery, like it's worn out. Which is impossible because I only bought it two weeks ago. Do you think Samsung technicians can fix my phone or should I replace it with a new one?
You can always replace the battery if that is the problem.
Nowhere did you say anything about the Bluetooth wifi module. Where is the Bluetooth/ wifi module or detector?
It should be the large square chip soldered to the top right of the motherboard @2:28 in the video.
Great.
👍✌
Earpiece speaker have foam balls?
not sure, I believe it did but I don't have it on hand to double check.
NICE
Could you please tell me if this Phone has E-SIM support?
As of release it doesn't but they mentioned they would be releasing a software update to enable the feature down the line.
@@PBKreviews Thanks!
@@davidjuan. 👍
Nice
👍
Does s21 fe 5g has cooling chamber?
yes, you can see it @4:35 in the video
you are the best
Thanks! 😀
Thx buddy 🤧
You're welcome 😀
Hello Sir i have one question, the sales person by mistake inserted the sim opening pin in the mic opening instead of sim tray in Samsung s21 fe. Please advise will it damage the mic. Keeping my fingers crossed.
Hi, no it will not be damaged. Mic and filter are seated above the hole.
@@PBKreviews Thanks a lot Sir for your kind reply 🙏. It was a big relief in India with Exynos 2100 processor it USD 400 USD phone, we don't have the Sanp Dragon 888 version in India.
@@gauravsaini5539 mere ko 27k mein mila tha BBD sales main
Did the gasket safe after this mistake ? Is it sill stop the water going inside the phone though that hole ?
THX
You're welcome
It is still water resistant after opening or not?
No, you would need to re apply original pre cut adhesive to retain the resistance. They sell the adhesive for the back as well as back cover/battery door replacements which come with the adhesive pre installed.
How did you get the phone so fast?
I got it from someone on eBay
Thank you for this video. I am looking for a unicorn I think...I tried to get my data recovered from my s21 that took an ocean swim. The data recovery specialist thought they could... but finally could not. Said "Yeah, there should be a way to fix it but it will need someone who is
experience with Samsung phones and who has access to schematics". Could this be you??
You're welcome. No I am not that familiar with that field of work to help you there, sorry.
So my 21fe took a rather hard fall and the Bluetooth connectivity was effected, my phone has since taken another fall, the Bluetooth is the same glitchy but now i cannot detect let alone connect to wifi networks. It shows no networks and therefore doesn't connect to any either. Is something came loose? Appreciate any help.
It's possible a cable may have gotten loose or the motherboard cover may have gotten loose but also possible the chip got damaged from the fall. Might have caused some solder points under the chip to break. You can try taking it apart, and re assembling or checking to make sure everything is in place. Aside from that, if its the bluetooth/wifi chip, it would either need to be reballed or replaced by a repair shop that can do soldering.
@PBKreviews I hasn't noticed your reply , or the fact that this is a video I'd already requested help on. I will contact my repairman for help . Thank you for your time.
What part or antenna controls the wifi/bluetooth, dropped the phone and ever since, those 2 features are not working and samsung wont cover it under warranty, so the phones essentially useless.
Plugged in my Samsung to charge while I showered it showed 68% and when I came back it would not turn on at all now I guess I'll pop it open and see if I can find out what happened.
Does ip 68 rating remains after disassemble after battery change
If you replace the adhesive with the original pre cut adhesive for the phone then yes, if not then no.
@@PBKreviews if I give it to officially service centre will they use glue
Very good 👍
👍
TY
👍
Is the ip68 still be good?
if you install the original pre cut adhesive made for the phone properly, then it should retain the water resistance.
Watching this from an s21 fe feels like a threat to the phone somehow lol
lol :)
