iPhone 3G keeps losing signal/service
Text:
| == Problem: == |
| iPhone 3G loses signal randomly and for no obvious reason, everything else works just fine. |
| == Circumstances: == |
| * Until a few days ago the phone has never been dropped. Then it was dropped from about 1 meter, twice... |
| * The phone is just over 1 year old |
| == Tried: == |
| * Waiting |
| ** Nothing.. |
| * Rebooting |
| ** Brings service back for a while |
| * Activating and deactivating flight mode |
| ** Brings service back for a while |
| * Re-seating sim-card |
| ** Brought back service initially, but didn't solve problem |
| == Theories == |
| # Loose cable? |
| ** I don't see how that fits in. I mean, re-booting gets the service back. If it was a loose cable it shouldn't help to re-boot.. |
| # ?? |
| # My observations indicate that the phone is only ever on 3G network. Could the problem be in or around the UMTS chip? |
| ** Considering logic board replacement or contacting someone doing BGA soldering. |
| == Update 1 == |
| Yesterday I changed the whole dock assembly to see if that could fix the problem. |
| Today it lost connection again. So it didn't work. |
| Now I'm considering to get a new iPhone or doing a logicboard replacement on this one.. Also I could find someone local that does BGA soldering and ask them to find the chip that has to be loose on the logicboard... |
| Either that or I'll decide that I can't afford it because I just bought an iPad.... |
| I also added a third theory. |
| Either way, thanks again for all your help and comments! |
