My Android Huawei G510-0100 phone.
Although cheap and it punches above it's weight it has random features that make it a pain the arse.
When I connect to the pc to charge it wipes everything from my music player and occasionally uninstalls apps. The music is still on the SD card but wiped from the music player. I don't press anything just connect via a USB cable.
Huawei seems to no longer have any information on this phone on it's website...
