So, Know them neat little panels you can turn on in chrome://flags? Now forget about them! you never seen’em! got it?! Now scram kid. Seriously though, apparently they’re gone with the latest chrome Version - 54.0.2840.6 dev-m (64-bit).
Thats my Home screen.
This might help someone having these no service/ no sim card no gps fix issues with the galaxy s3 i9300, that might have to do with efs folder change and IMEI corruption.
Okay so i solved these no service issues and ill share my experience so maybe someone will find it helpful.
