Default [Q] Reicast (dreamcast emulator) restarting the phone

My phone was on android 4.3 and everything was working fine with the emulator but after I updated the device to 4.4.2, randomly when I try to run a game, sometimes it restarts the phone. In San Francisco Rush 2049 this problem ALWAYS happens before starting the race & sonic adventure (pal) when select refresh rate.

Note: I tested with all official & unofficial builds to see if this problem appeared only in some more rescente version or if it's a problem with 4.4.2 and found that in all of them the problem happens.

My device: Galaxy note 3 SM N9005 (Snapdragon 800)

There anyone else here is having the same problem?

sorry for my bad english
