Howto Fix Google Play Store Not Working in Smart TV (Android TV),#GooglePlayStore #SmartTVPlayStore #AndroidTVFacebook Page : Aweek ago I was unable to download anything from google play store, it just didn't do anything when I clicked download. Tried clearing cache and even factory reset. Seemed to get worse, now as soon as I click google play store I get the message "Unfortunately, Google Play Store has stopped." About2 weeks ago I put my phone on flight mode on a plane and when I got off and turned the phone on and flight mode off, I got notifications saying "unfortunately contacts has stopped working" and "unfortunately gallery has stopped working" and have not been able to access either ever since.Tapthe Camera app and choose Force stop. If this doesn't work, try restarting your phone. To do this, hold the power button, select Power off, and leave your phone off for 30 seconds to a minute before turning it back on. Then check to see if the problem is resolved. Even if it works, this solution may be temporary.
