How to Play Pokémon Go in High Accuracy GPS -mode with Oneplus 2 of CM13? It is possible to play Pokémon Go in GPS only mode in Oneplus 2 of CM13 as described in the thread Can you play Pokémon Go on Oneplus 2 with CM13? However, the application does not work in the high accuracy mode with the device. I would like to understand which technology Wifi/Bluetooth/... is disturbing the game and GPS, in order to understand how to play the game in the high accuracy mode. 
I have not seen the same problem with Samsung Galaxy Phones of CM13.

This is Pokemon's server side problem. You cannot do anything here but wait that the company improves. Now, the situation is better.
