Lost network Connectivity s21 Ultra

[jimmyrinse]

Had the phone since release day with no issues until today, not sure if its anything to do with the update that was released today or not.

Started throwing up a roaming error even though i'm at home which went on and off a few times, now I have zero connectivity from my sim it just shows like a no entry sign where my signal strength should be.

I've tried restarting the phone, resetting network settings, tried sim in another phone, put 2 sims into the s21 but both show no signal, manually set up apn settings with no change.

OK so it's randomly just started working again

Although strangely  my keyboard has changed back from gboard to the stock one

Spoke too soon, have bars of signal now but nothing works 😡

There is a bug where it has to be connected to a pc or a charger. Mine works only when connected to a PC when trying to wipe cache

Hi after all fails do a factory reset, I know its time consuming but it usually fixes most issues.

Yea was really hoping not to have to do that. 

In the years of owning xiaomi phones never had to do that. If it happens again ill be dumping it and going for the mi 11

Great.....did a factory  reset  and its exactly the same

Contact Samsung customer service.

Getting an exchange. 

Not impressed at being without a phone for up to 10 days, and the call centre half way around the world where you can barely hear the person on the other end isn't what I'd expect from Samsung.

Not a good 1st impression at all

At least your getting a replacement, that's strange with the telephone call, when I call them it's like a normal call very strong communication.
