I have a Lumia 900 and anytime i play something (music or video) and the audio comes out of the phones speakers, after not too long the phone tries to do an app switch. At first i thought i was just "holding it wrong" and hitting the back button. But i can duplicate this almost every time with the phone just laying on the table. Is this a known issue with Lumia 900? I dont remember this happening with my Focus or Focus S.
