我一直覺得是韌體問體，如果有人送修發現是硬體問題（例如零件鬆脫或主機板損壞等），也請分享一下吧！
im using the lumia 920 for about 4 months & it was a awesome phone i liked every thing about it. since recent i'm facing the current issues
1. the phone compass does not work any more
2. gyro doesnt work (so no more racing games)
3. auto screen rotation does not work
4. cannnot set the screen brightness to auto mode
5. on call screen doesn't go off when u bring the phone closer to your ear.(due to this the calls get disconnected when the screen touchs your face)
6. the lights in the windows key, back key & the search key does not light anymore.
7. cannot run the Here lens app (says your device does not support motion sensor)
But every thing else works perfect. i did a reset, tried every thing i could but its still the same. is there any body else who faced the same issue or is it only me?
不負責 Google 翻譯
1。手機指南針行不通
2。陀螺儀不工作（所以沒有更多的賽車遊戲）
3。自動屏幕旋轉不起作用
4。 cannnot屏幕亮度設置為自動模式
5。調用屏幕上也不會熄滅當u將手機靠近你的耳朵。（由於斷開呼叫時屏幕觸動你的臉）
6。燈在windows鍵，返回鍵和搜索鍵不輕了。
7。鏡頭應用程序不能運行（說你的設備不支持運動傳感器）
