Hi all,

Have had a Fold 4 on EE for around 18m, always been a decent signal.

A month or so ago, the signal weakened... I took a domestic flight and when I landed, flight mode off .... no signal in a known good area.  Tried restarting etc., no good.  Wi-fi was fine for calls etc.

Tried searching for network manually, only one network Three came up occasionally then nothing.  Tried restarting with and without sim, reset, clear cache.... nothing worked.  Sim is fine, worked in another phone and other sim in, no good.

So, I reset it once again, left it plugged in charging (it had maybe 40% charge) and switched off  for a few hours and it worked on restart.

Been fine until today, randomly on a drive, at my destination it had stopped.

Before I reset / return if required, any other ideas maybe?

Thanks

EDIT:-

Tried clearing cache
Tried switching to flight mode on / off several times
Tried resetting all connection settings
Soft reset
Starting in "safe mode" I still have no signal.  Not on EE, and no other networks found.
Full reset done, still the same so sending back to Sammy.
