Hi. I periodically lost signal GSM (I include only GSM, WCDMA off). Nearby there is another phone and have it in the same place with the reception of GSM all ok. I have a question. This problem firmware? (I have not changed anything after the purchase,-The conclusion only update – http://www.thaiandroidphone.com/thread-24251-1-1.html)
Or do I just caught a bad exemplar phone?
Thank you.
