Android 8.0 Oreo comes with some bugs fixes and security patches. Every year Google is launching its new Android version with the serial wise alphabet on the bases of sweets.  The ratio of android Oreo is only 3% and still, most of the phones are running on Android Lollipop. But companies are trying to overcome this ratio. Let see in the coming future what will be the ratio of the android version of the devices.

This ROM is personally tested by me but screenshots are from Xda. The battery is average, on a full charge, it will last you for 8 hours. Stock android always looks beautiful and many of the users don’t like custom skin UI. Whenever this ROM gets the update.
