My S21 (SM-G991N) is just around my room so I want to give it a fresh vibe but how?? I dont know how to and I also wonder could be any interfere or other known issues
For so long, I wanted to keep going with this phone. For years, it had been truly great.
That is, until the past year. Camera blurriness issues, battery draining, wifi and bluetooth randomly dropping, malfunctioning NFC...I thought my phone was going haywire. That, and the lack of future upgrades or security updates was enough to finally make me give up.
I swore I wanted a Pixel, but all the bad reviews made me go back to Samsung, so I finally ordered the S26 Ultra. So after 5 years, I'll finally be leaving this forum. It's been real!
How much longer will the Galaxy S21 likely receive monthly Google play system updates? I know it no longer gets Samsung security updates, but the Google Play System updates do increase security somewhat.
When I originally got my phone it had its nice original Samsung battery, that expanded withim 7 months.
I got it replaced with another original Samsung battery, that lasted 2 years before loosing its capacity.
finally, I replaced it with a cheap aftermarket one, and wouldn’t you believe it, it’s lasted all this time and still hasnt shown a tiny bit of expansion.
is it just me being really stupidly unlucky or is Samsung really bad with their batteries? My S7 Edge, and S9, both on original batteries that last long, but the S21 being on its 2nd battery due to EXPANSION of all things is really concerning to me.
For anyone wondering, I live in the UK, my room where I store my phone when it’s charging is cool, I don’t actually use it for heavy gaming, so what has caused this?
Hey everyone,
I've had my trusty Galaxy S21 Ultra for 5 years now, and it has been absolutely flawless. Unfortunately, back in March, I dropped it and broke the screen, so I took it to a well-known local shop to get it replaced.
The first replacement screen they put in was clearly defective, so I complained and they replaced it again under warranty. This second screen looked much better, but ever since the repair, I noticed the phone running significantly hotter than it ever did during my previous 5 years of usage.
Now, out of nowhere, this very thin horizontal white line just appeared across the display (image). It’s mostly visible on lighter backgrounds. The phone hasn't been dropped or suffered any impact since the last repair in May.
Has anyone else experienced this line issue connected to overheating after a screen replacement? Could it be a bad connection, an adhesive failure from the heat, or just a cheap third-party panel?
I’m planning to take it back to the shop since it's under warranty, but I wanted to hear your thoughts first so I can be prepared when arguing my case. Thanks!
June 1 Google Play system update downloaded through settings | about phone | software information. Then press Google Play system update.
Once again, it should address the security issues below:

Since it is being pushed by Samsung, it may also address the CVE found in the Samsung software. https://security.samsungmobile.com/securityUpdate.smsb
How much longer do you plan on using your S21? I plan on using mine for another 2 years, at least? I think my apps should be supported on Android 15 at least that long?
My s21 fe is starting to get slower every day i use it, i don't know what to do. It heats like crazy and battery dies fast. This is the first flagship i ever owned and i have been thinking about doing a switch or maining a iphone 7 for now as the s21 fe is getting heavily unusable. I am thinking of switching to a a56/a57 or another fe series like the s24 fe i don't know what to do. I recently had to bring it on a 2 day trip and i had to have a charged powerbank so it doesn't die . The battery was changed last year on april a few months of owning it since january 2025 should i repair it again or switch?
Should i update to the update after jan security patch? Will it slow down my phone? (S21 5G)
