hey guys im actually really annoyed because ive tried a new app, called runtastic. its a fitness app which records your run (route, average speed, time, elevation…) so now the problem is that it seems that the app is closed after a few minutes while the display is off because when i took a brake, the screen was white and the app seemed to Start again. so i tried A few soloutions e.g lock the app in Multitasking mode, added an exception in security center at battery > keep apps activated while screen off. AND IT ******* NOT SOLVED MY PROBLEM !!!

here is a Screenshot:

(green=Start , red=where i fininished recording)
