can't install or update apps while in mobile data plan but working in Wifi I have Nexus 6p phone. After the update to Android 7 my phone cannot install or update Apps from Google Play Store but it is working fine on WiFi. After Android 7.1.1 update the phone battery is draining very fast 100% = 2.5hr &amp; heating Problem. I removed the updates for play store, changed permission too, but still nothing worked out for me.
If you also disabled limits in downloader, maybe firmware is  bugged? Try to carefully reflash your device.
