How do I upgrade the Android 4.4.2 (KitKat) to Android 6 (Marshmallow)?
Oh, I see. Is there any other way to upgrade my Android version?
Yes, you can try rooting your device and installing a custom ROM that runs on a newer version of Android. However, this process can be complicated and may void your device's warranty. It's best to research and backup your device before attempting this.
