I am wondering if there is a way to get the app store back on Android 5.1 so if there is not can someone help me with installing apk files is says there is a problem parsing the package. Pls help
This has to do with how old your phone and its Android OS version is, as discussed in your other thread: https://forums.androidcentral.com/t...count-error-and-updates.1059909/#post-7163037. Your only option is to see if you can flash a custom ROM with a higher Android version, as you mentioned in that thread, but I wouldn't be optimistic about it.
If you're unable to install an APK file on your phone, that means the APK is not compatible with your phone.
