first of all, if it's not right place ask question, please guide me.

recently users of application complaining phone freezes , restarts while using app. question how can app freeze android os? there chance that? if yes, possible causes behind it? how can isolate issue? (one of user uses device sm-g900v, android os 5.0)

in debug mode ran app , continuously used it, , found thead count not coming down , gradually increasing ,i noted thread names. used ddms in used update thread option , checked thread getting created. in case media related thread not getting released(its system thread). made sure gets released time . boom problem solved :)
