A true Samsung flagship the legend, the myth. This phone was like releasing iphone 6 design back in 2014. It might look like the display is flat but it is actually slightly rounded, 2.5d edged. So the samsung still got it. Will probably import from China or Usa for snapdragon versions. Also like 200 dollars for a ligthtweight flaghsip chip phone? Used to pray for times like these man

If you update to android 15, one UI 8. I'd suggest you turn on ram plus and set it to 8gb. You would never experience any performance issues again

I just got my phone, realized it was running android 11 decided to update it to android 15, overall performance has drastically reduced, I mean it.
I wonder what the 'update' was for

I just updated to android 15 (One UI 7.0).
Overall performance is still the same, I'd say this UI just feels a lot lighter, feels like a pixel but looks diff.
Now for the green line issues, it is caused by heat. This is not a phone to keep I'm a pouch whilst it is charging or when it's warm. Overall, I'd say for a 2021 device, the S21 still holds its own. But you have to handle this device with extra care.

I bought this phone refurbished and I have been using it for about a year. It's currently running One UI 7. It's actually pretty snappy for a 2021 phone(if you set processing speed to high and disable ram plus). Only bad thing I have noticed for now is the battery(could be because i bought it refurbished). I'm getting 3 to 3:15 hours of SOT. I mostly use it for web browsing and social media. Overall it's a great phone and I will keep using until it breaks or until Samsung starts innovating again.
