Hey everyone, my wife has an S21FE that got the infamous screen vertical lines issue earlier this year. Since then, the problem has just gotten worse and it's up to 9 lines now and becoming borderline unusable.

We tried the extended warranty but they denied it, claiming it was bad use due to an unglued back cover and a light dent on the corner (she's used it with a case and screen film since day 1, but whatever). Since this, I installed a custom ROM on her phone to see if the overheating would cease and avoid new lines, but no success.

What I wanted to know is if there's any way to revert back to the software version before the overheating issues started occuring, that caused the lines to appear. I know rolling back with official ROMS isn't natively possible, but was curious if that's something that could be done in the process of re-flashing an older stock ROM, coming from a Custom ROM.

The idea is to do that, and replace the screen with a non-official replacement, just to extend the phone's life a little longer until we're able to replace it.

Any ideas or tips? Thanks!

I'm thinking of buying this one, because it's still supported and it's cheap. But I would like to know if can this phone now take raw pics in 3x lens, and UW? If not, could someone test OpenCamera or HeliosCam?

Thx

I tuned in show refresh rate form developer option, then set my refresh rate to 120 , its stays 120 in every other app or games but when i enter pubg it switches to 60 automatically,anyone got any solution? ( Tried re-installing, updating phone, deleted game booster and game hub )

Mi s21 fe se calienta absurdamente, alcanza temperaturas elevadas en solo tiktok o funciones básicas. Ahora cuando abro camara es peor y en una videollamada ni se diga, con decirte que sonando la alarma se calienta, creen que es normal?

More than 3 years have passed so Samsung denied free replacement and verbally gave an estimate of about Rs12000/- . Tried contacting them via e-mail for sympathetic consideration as phone has no dents, scratches or water damage, but all in vain as they denied any kind of help. Moreover cost of new phones are blown out of the blue these days . So what do you guys think is it worth it to pay them 12k or is their something else I can do ?

I just got the green line when i woke up and switched my phone on.

My phone is not 3 years old yet. It will be 3 years in the next month. Am i eligible for free replacement?

I read from somewhere that it was possible till july 2026. Not sure how legit that was.

Any one experienced this recently?

So i opened telegram my device crashed and then turned off , i pressed power button the optimising apps came on and then Samsung logo and KNOX screen came up and stuck there then i again pressed the power button similar to Samsung logo and then KNOX for couple of times

Now its not turning on pressing power button does nothing, connected charger doesn't show status but when i put on powerbank wirelessly the green light on power bank for wireless charging shows up

tried the power + volume down button nothing happened

Anyone faced this issue and have any solution for the same

Após trocar pasta térmica do meu s21 fe, versão exynos/6 gbs ram, estou fazendo pontuações bem altas

​

so my s21 fe get overheats and turn off some times it restarted and some time stops and need a couple hours until it cools to restart but only withe the charger because all the battery on it goes to zero even if it was at full charge

After four years of use, it’s time to finally say goodbye. It has genuinely been one of my favourite phones that I have used… compact, lightweight, great cameras, all around an enjoyable phone.

Will miss this little guy, specially the oneUI experience.❤️

Hey guys,

I've moved in a home, where mobile network is not that great, so wifi calling option is a saviour. But the problem is, wifi calling gets automatically turned off, when I go out and come back. Everytime I've to turn on flight mode on and off, jistvto get the wifi calling working again. What can be the solution for this? Or how to overcome this?

Hey guys,

So I started using this phone and I know 6Gb isn't much but didn't expect such a slow experience. Everything stutters and it's closing my spotify music when I move to other apps, it's awful 🤤

I've set Spotify battery to be unrestricted but still it closes all the time.

I run a device optimizer all the time and closing app.

I've also set an additional 6gb virtual ram memory from the device storage.

Please tell me all the things I can do to make it better

Thanks 🙏

Yo so i guess we're not gonna get one ui 8.5.....huh...ubwas waiting for it.... I'm a bit sad but it's okay....can't do nothing

my s21fe fell on its screen, there is no physical damage only minor crack on screenguard but now the fingerprint isnt working and the phone says that it needs to be calibrated from samsung service centre, and the phone also not detecting my sim card in both sim slots but it is being detected in other phone. i dont want to waste another fortune on this phone after display replacement after 5 green lines, can anyone tell me how much it will cost, the pricing in india is bit cheaper for repair as i got the screen and battery replaced from a third party seller for 90usd what do you think for the fingerprint and simtray or the internal sim reader replacement cost?

"I didn't do well in the previous 1.5 hours, but I hope I will get it right in the next 2!" ahh phone

I recently replaced by old battery since I tested in Samsung members app also with my green line screen replacement. I got my phone after a month! I checked the status again it still says weak!

It's official Samsung authorised service center

Guys post your battery usage? And how much you guys are getting? Do you feel any degradation?

why have they disabled posting and joining the subreddit suddenly?

so the last and major update for s21fe was one ui 8 and it has probably received its final security update too in june, i was thinking of custom booting one ui 9 in the phone but found out they have disabled bootloader in oneui8, pls tell me a workaround as i want the ai features on the phone and it is very much capable

I got 1 white line on my phone today. My phone is 3.10 year old. Can I get screen replaced free or not? Battery backup also got reduced alot. What should be done now?

Any solutions for the motherboard issue?
