One of my friends purchased the phone back in 2014, he denied every update when he got the phone, now when he checked the system update, it says it has been latest, the version is Android 4.4.4, we tried Samsung Smart Swith, but without luck. BTW, the device was rooted before.
I want to know that if it’s possible to upgrade to any later Android versions? Since the 4.4.4 version is as much as too old. Any help would be greatly appreciated. Thanks in advance.
Have a nice weekend!
