后台进程在三星S3上运行时随机死亡

I wrote an Android app which runs without problems on every phone I tried except Samsung S3. What happens is that, while my app is running, other background processes (other apps, that is) will start dying. For example, after some time of using my app, Live Wallpaper will die, and user will get a black background on his phone after exiting my app. And finally, after some time of using it, my app is also killed by OS. What's frustrating is that I cannot see any error message in log which would give me a hint as to what exactly is the problem.I wrote an Android app which runs without probl
