CompuMatter deals with Apple, Android & Windows phones
We do not have anything to do with the data plans of the phones themselves, we only resolve software and hardware problems common to those phones.
Software problems include:
Freezing, slowness, app specific issues, data recovery, upgrading, printing, port drivers and so on.
Hard problems include:
Broken screens, ports not working, power problems including battery charging, replacement power plugs and so on.
On the Apple side there is essentially one kind of phone available but with many model variations. That of course is the iPhone. However, within the iPhone there are of course multiple screen sizes, multiple generations ie; 3, 4, 5, 6 and their derivatives ie; 5s, 6s and so on and and of course multiple versions of IOS (iPhone Operating System).
On the Android side of life things get more divided since any manufacturer can put the Android Operating system on their devices. Just like with Apple there are numerous versions of Android ie; 1, 2, 3, 4, 5 and recently 6 and of course their associated names ie; Ice Cream Sandwich, Jelly Bean, KitKat, Lollipop, Marshmallow and so on.
Windows phones share a lot of common elements and ideals at the later tile windows operating systems. More often than not, the problem has more to do with software / configuration issues including things to do with the Microsoft cloud storage system.
