1, sensor not working properly, it doesn't off the screen automatically while on call, so that different options are being accessed automatically even disconnecting the calls. We have purchased 3 mobiles and all are facing this issue.
2, I don't find "compass" app given by default.
3, while talking a call sound should be some more.
