Coolpad Mega 2.5D is one of the most premium phones available at this price tag. Phone looks great but playing high end games it is not supportive. 3GB Ram makes the cellphone faster. Phone is able to record HD Videos. I am now using a 4G sim in this device but the speed is very good. So, I am not feeling bad for not using a 4G. Speaker sound is OK, not so loud but I am satisfied with the speaker at this price range. It supports OTG and also hands free devices like Bluetooth headphone. Ships with Android 6.0 Marshmallow. No heating problem. Non-Removable Battery and does not come with 2amp charger. Battery is okay. The 2500 MaH Battery lasts one full day on normal usage.
Its a quite impressive device with a price tag of 6999.
