just bought a new phone from ZTE and have been listening spotify continuously on this phone with no problems at all. But these days, whenever my phone goes to sleep or i lock my screen, the music stops playing and when i unlock my phone again, i find that the spotify would have been paused and i have to play it again. Its getting really annoying to keep scrolling through the music so that my phone dont go to sleep and the spotify wont turn off. I try to look up in the internet for the solution but nothing worked for my case. What would be a good solution for this issue?
