I needed a new mobile and considering the proliferation of iOS devices I've collected, decided it was time to dip a toe into Androids so I am now the proud owner of a cheap as chips Samsung Galaxy Fame PAYG.

I'm fairly impressed on the whole, but it's worse than useless for network data access. I only have 2G (gprs) coverage locally, but my previous phone (pre-android and pre-iOS) coped fine, if a bit slow, with the same SIM. The Android just seems to give up on almost every attempt. I have checked and double-checked the configurable parameters for the access point and anyway, the fact that it works occasionally suggests the configuration is basically sound. I've tried it in the nearby town centre, much the sam - nearly never works.
When not working (which is nearly always) the symptoms are initial flickering of the activity arrows under the 'G' (gprs) symbol, which peters out and stops after a few seconds, and then the App hangs for few tens of seconds before giving up, and reporting various error messages like 'can't access', 'try again' etc. The same symptoms affect all my favourite Apps, BBC weather, National Rail (train times), BBC News, etc. Yet they all do work, occasionally.
So to recap, signal strength is fine, and data connection does occasionally work, possibly it works best when the network is quiet like wee small hours. In consideration of that I'm inclined to think this is an Android O/S problem, rather than with the phone. Perhaps, for example, it can't cope when corrupted data needs to be resent? Or maybe it can't cope with long latencies?
Just wondered if anybody else had good/bad experience with Android network data, compared to earlier phones (pre iOS and pre Android)? I'm Android 4.1.2 for what difference that makes.
