Hi guys, I've bought a mi4c from china a couple of months ago and it's a very nice phone. I haven't installed any rom manually but only updated it via the ordinary updating system. One issue I've been facing pretty much from day zero is that background processes / tasks are very flaky and crash very often. Three examples are: 1) Nike+ (software to track runs) 2) Runtastic (as above) 3) spotify, specially if the wifi is on. Sometimes even maps crashes during usage... This issue is really annoying and it's, so far, the only issue I'm facing with the mi4c. Any idea?
