I am currently running Android 4.4.4 and every time I go to the app store it tells me the app is incompatible.
you are running a very old Android version then and that would be why. My version is 7.1.1 and I have no problems with updates.
Thankyou, I will try updating
to update the android version is a major system update and the hardware in your phone may not support it. Be aware of this before doing anything. Its like updating Windows or Mac on a system that is 10 years old to a current version... it probably won't work.
I would suggest researching your phone and seeing if you can find out what versions of Android are compatible.
