You should not expect a good quality camera from a budget OmniVision camera sensor that they installed in Flash Plus 2, the camera sucks, YES, specially in low light condition, very very ugly. Heat issue is normal while charging, the build is good except for the device large left and right bezels and YES just like you, I'm disappointed to this device, I will not recommend this to anyone. If only I could turn back time, I prefer not to buy this device and buy samsung device instead. Will what happen, happens, face the reality and just leave things the way it is. Lesson learn thow'.
