My S21 FE has the problem of having low and unstable network reception be it 4G or 5G. Also 5G was found to be working only on SIM slot 2 and not on SIM slot 1.
Also the phone heats within 10mins of normal usage (insta surfing).
I gave my phone to the service center. They did some checking and admitted something is wrong.
After 1 week I got my phone back. They told me my phone was perfectly ok and they couldn't find any problem and they only had to reinstall the software.
Yes, this fixed the 5G problem in SIM slot 1 but overheating still persists. Now recently, my SIM slot 1 has again stopped supporting 5G whereas it's working on the other slot.
Now my warranty period is over and I don't want to spend anymore money on a problem which the device/software has all these time
