Heating fastily is one of it's drawback. Also, battery drains out easily. Copy to mucro SD card option is also unavailable. Camera's shut sounds are never be decrease, even when we set mobile profile into silence. After a long use in the sunlight, it's colour changes. volume is not very sufficent.Sometimes, some application may misbehave.
