S21 Ultra mobile signal issue

[MohitUpadhya]

Hi All

I have started to face a very peculiar problem with my S21 Ultra which i can see that many users globally are facing now. So basically I use an Airtel sim in slot 1 and Jio in slot 2. When i am connected to wifi the mobile signal is fine. The moment i go on 4g and swtch on mobile data, on any of the sims, the cellular signal keeps dropping completely and returns full bar for a brief moment and then drops again. This cycle keeps repeating painfully and the phone becomes unusable to the point that it is pointless to have it and trust Samsung with quality. Globally users have tried everything as I did including factory reset but to no avail. Samsung just destroyed this phone and their reputation.

Use single sim. This is the only solution at this point of time.

[MohitUpadhya]

Is it working fine for you with single sim

[Ravi0883]

Yes in single sim solve network issues.

Same here.....the internet goes on and off on its own.
It's a lte hardware fault.....Went to the service centre.....they ran diagnostic tests and said it's ok.
Stay aloof from Samsung

Any updates on the same bro?

[MohitUpadhya]

There was a update released today but the same issue keeps happening. This is appalling for a phone this costly.

[SarthakPatnaik]

Really true.
Went to the service centre.They ran the diagnostic tests and said the phone is ok while I constantly face the same problem.
Time to try out other premium brands like apple.
Enough of Samsung

Yeah i find this very strange, sometimes a feel this is a deliberately created problem to render the phone worthless so you buy another phone from them in exchange for this. This has given me some serious lessons from going for an expensive phone again.

Even I feel the same
