Last two days since I use mobile jetwork my signal bar was down to two max sometimes signal even lost compleatly. And I found something interestinng, if I use settings WCDMA/GSM Auto my signal strenght is crap and network switches from H to E all the time. If I use WCDMA my signal is almost compleatly lost but I get only 3G (H) network, but if I use GSM only my signal is perfect (3-4) bars all the time, but I can use only G (E) network. Oh and I get crapy signal even if I dont use mobile network or Im using Wi Fi. So what should I do? How to get good signal and good network connection?
