I have had a g300 for a couple of months or so now and have been very happy with it, it's currently running the 936 NZ rom, and was unlocked via a code purchased on ebay. The problem is that it seems to have developed the proximity sensor issue that a few others have also reported, ie the phone blanks it's screen when close to your face, but fails to turn back on when removed. I've installed an app called 'proximity sensor finder' which show it reads 9cm when away from face, drops to 0 when moved closer but fails to reset to 9 when moved away, squeezing the top right hand corner of the phone front to back cause the sensor to trigger and read 9 cm again. So as I see it this is a hardware issue which would need a return to hauwei to fix (I bought it in a Tesco store). By unlocking via ebay have I blown my guarantee? If not, do I need to reflash a different firmware, i've read the NZ rom is md5 identical to the recently released UK OTA update so can i just leave the NZ rom on there?
Any suggestions gratefully received.
