Pokemon Go 0.35.0 on ZenFone 5
Possible issues
 1) You did not provide all the necessary permissions requested by the app to function properly.
 - you need to go to the settings -> apps and check the permissions.


2) Your network might be an issue.
- check the data transfer rate while in the game, and see if there is data being transferred when this happens. if not more than 2kbps then there is a high possibility of this being the cause.
