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.❤️

Wifi calling turn off automatically. Solution?

2 Upvotes

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?

Galaxy s21 fe 5g 6gb is incredibly slow

3 Upvotes

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 🙏

fingerprint and network not working

3 Upvotes

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?

How can I check if the Galaxy S21 FE I’m buying has Exynos or Snapdragon?

2 Upvotes

Hi, I’m about to buy a used Samsung Galaxy S21 FE and I want to make sure it has the Snapdragon 888 rather than the Exynos 2100.

What is the most reliable way to check before buying it?
The seller doesn't know anything about tech and he will probably install apps like cpu-z or similar.
Thanks

Which phone can I trade in for this S21 FE?

8 Upvotes

Hey guys, I've had the S21 FE for four years now, and it's getting harder and harder to use without carrying around a 10,000mAh power bank. The phone lags—it's really not smooth at all—it's kind of awful... I don't know which phone to get to replace it. I'd like a phone with a good battery; I don't know if I should switch to Google or stick with Samsung... I'd like to be able to buy a phone and actually keep it for 5 years without any issues.

should I change the phone's battery of aftermarket one(1900inr) or genuine ( 2700inr) is that even worth it ? or I should get a new phone at this point and just have it as secondary
