Suddeny after an update my tablet keeps popping up that certain apps will not run without Google play services and Google play services are not supported by your device. The tablet came with Google play services installed. Google play store has disappeared from my entire tablet. Many many apps are not working. Model number : Sm-T580 Help!
My tablet did this as well, and I had a hard time getting it fixed because it wouldn't connect to the Internet. I had to use the Internet app to correct it. You just need to update your Google Play Services and it will be fine.
Let me clarify my last statement. The tablet by default was trying to use Chrome. It wont connect to Chrome if your Services need updating. Therefore, I used the internet app to correct the problem.
When mine gave the error that it wouldn't work without the services, mine face an option to update. But when I clicked update it would try to connect using Chrome and failed every time because it needed the services. However, I have an internet app on mine. It finally connected and updated my play services and everything was working fine at that point.
