Hello, I have a problem after screen replacement, normal signal strength in my home was about ~-63dBm 25ASU (5/5), now its -99dBM 7ASU(2/5). On markets and other big closed buildings I have no signal. (normally i have full 2G signal) I buy new antena cabel and nothing was change. I check with two diffrent sim card - this same. Enyone know what i should check and how to solve this problem? There is no problem with wifi and bluetooth signal.
