GT-i9100 network trouble!!
My brand new GT-i9100 is barely usable. I've spent the last week wrestling with it (bought it new from ebay) to get it to work, but I'm at my wit's end. Any help would be greatly appreciated. Here's the problem:
My Galaxy S 2 (now rooted and currently running SlimRom) partially or completely loses cellular signal about 60% of the time, often in places where I know there is reception. I'm using Telus' network in Canada. It will lose data, lose ability to make or receive calls, and fail to send text messages. The indication of signal loss is not clear, IE it will say "emergency calls only", "no service available", or even say I have service but I really don't. However the cutting out seems to occur consistently depending on where I am located. For example I seem to get OK signal at my house, but zero at my friend's house. I know it's not the network in this case, since my friend is also on Telus and they get fine reception.
I've done some testing and here are some possible causes that I can think of:
network cold spot - No, see example above. It also cuts out in urban populated areas where the signal is strong
- phone compatibility - unlikely, since Bell offered the i9100M, which I'm led to believe is physically identical to the normal i9100, and Bell and Telus operate over the same frequencies. Also when it does get signal it can transmit data fine
SIM card - No. The first thing I did when I discovered this problem was get a new SIM card. Nothing changed
SlimRom - No. The phone was acting like this out of the box with the stock image.
- Radio firmware - Unlikely. I've flashed at least 6 different firmwares, including KG6, KH3, LQ6, LP6, KI4, and even LD3, which I believe is the firmware the Canadian i9100-M ships with, so would logically work fine. The carrier for that was Bell, and I believe Bell and Telus operate on the same frequencies
- a hardware defect in the design of the phone or the antenna itself - the last possible option I can think of. I hope it's not this, because then I would have to undo all the modifications I've done in an attempt to fix my phone, and pray the seller accepts the return
Please, if anyone could offer any assistance that would be great.
