Nokia Lumia 925 faulty issues as below : -
1. Deleted the camera roll file, but it seems like the photo are only hidden. Thus It results a problem such as Phone Storage problems (this does not happen in my Lumia 920 Amber firmware)
2. Volume rocker issues even though I already set it to '0'
3.Entering the qzone.qq.com makes my music stops
4.The screen of the contrast goes crazy when turned on Battery Saver Mode. This issues really are annoying since the colors are always off when watching videos , play games and browsing pictures.
5. Lastly, There are a issues the same as Lumia 920 about Nokia Smart Cam black bars.
Awaiting for a response from Nokia US regarding my issues, but still the Nokia Care team did not contact me for almost 2 weeks.
