information at risk. Always update through your phone’s online update feature or send your phone to a nearby
authorized Neffos service center for assistance.
2. Your personal data will not be erased during a system update unless you have installed an incompatible app. It is
better to back up important data before updating your phone.

banking applications and games. This is because it takes a while for third-party application developers to release
