* After the first installation, system ask to use SD as internal storage, and need to format the card. ("i don't like to loose my file so i select as external storage")
*After Upgrade Lollipop to Marshmallow some of the Apps not worked, when i try to uninstall it after few seconds system reboots, i don't know its the nature of the OS.
*in lollipop unable to move the whats app to SD card, now its possible move to SD card, after moved the app to SD card system responds very slow i don't know the reason why?, now it fine and working smooth.
*some of the UI are changed need to check that.
Note: i forced the device to get the Update
