I use a Samsung Galaxy GT-19195. Two days ago I lost virtually all signal strength. My wife uses a £59 Nokia on O2 PAYG and gets 2/3 bars...! Before I lost it it showed a comfortable 2/3 bars G4.
I have tried all O2 suggestions without success.
Any advice will be greatly appreciated.
I am in my eighties and have no landline, so my mobile is pretty well my only contact with the outside world...!
