Hey. I really don't know a lot about 2g and 3g technologies and maybe my problem is operator related, cause I couldn't have opportunity to check other one. I've been experiencing strange 1 sec connection drops while conversation during voice call. It's like I have a pause for 1 second and during this moment I can't hear anything till the conversation gets back. No total call drop etc. So after making some experiments, I realized that it's due switching from 3g to 2g during a phone call, for example, when I start a call my phone is on 3g (whatever - H or 3g symbol) , sometimes it is sticking to this mode and my call quality is perfect, but once it switches to 2g mode during a call, right at this switch my phone seems to lose a signal for 1 second and then gets back. After that the phone is being stuck to 2g and call quality is fine. It's extremely annoying sometimes, especially when I have to ask the person on the other end to repeat what he said during that break. So your comments ? What could it be ? Is it due to operator or my galaxy s2 is faulty ? Or maybe it's just normal ?
