Pls can someone tell me how I can update android os? A case study is the latest MTN S620 which runs on 4.4.2 kitkat and we that happens to buy ours at first week of introduction bought the one running on 4.2.2 jellybeans. Needs tutorials or apps to update the OS. Or if anyone who can create a backup of the same phone whether it can be use to upgrade the older OS.
