Why does Glory v40 always stay in your pocket?

The ability of receiving signals by mobile phones is very poor.

1, the mobile phone has poor reception ability. When approaching the human body, the signal will be weak due to the occlusion of clothes. 2. The local signal network is unstable. There is no signal when the mobile phone is in your pocket. If there is such a problem in the mobile phone, most of the reasons are that the smart power saving mode of the network is turned on when the screen is locked. At this time, we can turn on the mobile phone to optimize the network settings at home.
