I decided to give Android another try, after having used an Xperia Mini 10 a couple of years ago (which was just unusable due to extreme battery rundown). Chose the cheapest of the cheap this time - a samsung S5300 pocket. It looks promising so far in the way that it seems to last nearly as long as my old dumbphone in standby when used sparingly. However there is one huge issue. Exactly like my old xperia mini did, the 3G data connection freezes. After the phone has been on for like three hours, the signal will still be okay and the H/3G arrow symbol will still be there, however, the arrows don't blink and no data goes through. I can still make calls and handle SMS when the phone is in this frozen state. A reboot always solves the problem, sometimes just switching off packet data and turning it on again works. I've tried both the prepaid sim card the phone came with, and my old sim card on a different Swedish operator. Same problem with both. Any idea on how to solve this issue? Is it a common android problem?
