The Samsung Galaxy S3 has been a handset that was well received but it is now getting older and as usual, updates are being stopped. It currently runs on Android 4.4 KitKat, which means it isn’t getting Marshmallow. However owners should not worry too much as the device can be updated to Android 5.0 Lollipop and this is sweet enough.
Before you rush into going ahead and updating the Samsung Galaxy S3 to Android 5.0 Lollipop you will need to make a backup of your device and you can do this by way of Nandroid. Bear in mind that you have to have custom recovery installed along with having root access enabled.
