Asphalt 8 prevents loudspeaker from turning off / sleepmode
So I got this game, and it leaves the speaker on, whether I lock the device, or exit the Asphalt 8 game, the speaker keeps hissing, giving me wake-lock usage, preventing phone from going into sleep mode. Anyone else have this? I also had this with Need For Speed Most Wanted for Nexus 4.
A quick fix for this is to turn off the application process, but when for example playing the game in the class, and then you have to turn the phone off, but you don't want to lose race progress you have to let the speaker hiss through all the lesson, or even worse, if you forget you end up having wasted battery after school. Please someone help me.
