So here is the issue. My tablet is not connecting to the internet. It can connect to the wifi and even say connected but there is no internet, including mobile data . It can call and accept calls, the Bluetooth still works but is much slower, Xender also works for photo and video. But if I send an app through Xender, it installs it but when I click the app it takes me to play store and say there is no connection and I couldn't open the app. When I go to telegram, it alternates between connecting and updating in a second interval but it doesn't update a thing. What should I do? FYI : I HAVEN'T OPENED THE TABLET FOR ALMOST THREE/FOUR MONTHS AND LEFT IT TO SIT UNDER NOTEBOOKS AND PAPERS. THE ISSUE HAPPENED AFTER I POWERED IT ON AFTER THOSE MONTHS. IT WORKED COMPLETELY FINE BEFORE THAT.
