This device is having decent hardware configurations but poor performance.
Every charging may lead device to long sleep and never wake up. Works only when removing and reinserting battery, even power button don’t work.
The device seems to be installed with fraudulent Apps, unnecessary Apps.
Device is not receiving 3G network, even if you try to uncheck the "use 2g network to save battery option", unable to uncheck, it will check it again when you visit back to mobile network settings. So, you will get 2G network/GPRS/Edge only.
The device heats up upon extensively usage like navigation, high graphics game etc. 5. Poor battery. There are many more, let it be. This device is not for me.:-( Thank god I experimented on a low-end device.
