[Q] Signals Problems after 4.3 Official Update
I'm from Argentina. (Excuse my poor english)
I have a full stock S4 i9500, bought to Samsung (without any carrier logo, unlocked).
During christmans night i received a notification about a new update available, i just downloaded it and installed it. Phone is now on 4.3 (Knox and other stuff are now available).
Since that update, the mobile signal is working very bad.
Every 2 or 3 hours signals completly goes off.
If i restart the phone, or turn on/off airplane mode, signals come back.
If i just leave it, takes more than 1 hour to recover signal.
This is becoming very annoying, since i uses sms a lot with my girlfriend (she don't like smartphones) and also, im loosing a lot of calls during signals fails (when signal come back, i ussually receive a lost call message).
I searched forums for this same problem, but i just found people who had stock problems, and in my case, problem become with the new update.
I want to avoid full factory reset if it possible.
I can post any screenshot if needed!
