When you lock your phone, does that turn off the game in the background as well?
The game is rather bugged on my Huawei P8 phone it seems. I thought I could just go for a walk, start the game, lock my phone, and just stop whenever the game notified me of anything. Half of the time the game either seemed to have lost GPS connection whenever I locked the phone, or the map froze when I maximized it again, making me having to restart the game.
Seems a bit daft having to constantly look at the damn screen like a retard while walking. What makes a walk pleasant when I cannot even look where I'm going
