I tried to Format factory reset but still not working and also i am getting a notification "Unfortunately GPS Speed has stopped working" every second. I am fed up i did hard reset and everything still the Same issue unknown and Porn apps are installing themselves and more. Is there any Solution or Not i tried every thing. Changing Google Password, Un check unknown resources and even factory reset. What could be the reason that its coming again after factory reset

Make sure you are not restoring from backup....restore phone as new. See if it still occurs. If it does...then its probably an app you've downloaded.
