Phone is closing/opening apps on its own

[Storabananen]

Hi

As said, My phone is opening/closing apps and swiping the screen on its own..

It can open apps, close apps, swipe/change sites all on its own. 

And when it is in this state i cant even turn off the phone pressing the on/off button.

When it is in this state i cant controll the phone at all, i just have to wait until it stops wich usually takes a few minutes. 

Do you think this is caused by an app or is the phone malfunctioning ? 

I am using the app ''Master Cleaner'' do speed up the phone and it allso searches the apps for virus. No virus found. 

Thanks in advance !

I also had this problem, my phone keeps on opening/closing some apps and type some messages with it's own. I brought my phone last time in a repair shop because I broke my screen then after that I can used it properly but after I put my tempered glass it started to get weird. Please help me what to do. 

P.S - When I open my mobile data that's when weird thing happens.

I no longer own that phone, but in that case it turned out to be the screenprotection that was causing the involuntarify screen movements. When i removed it the problem disappeared. Maybe it had catched some dirt or moisture.

I had a same issue 3 times 3 different xperia. If you turn off the lights in your room and you will wach carefully your phone from side you will see the screen came off. If you push that part togather than its no problem anymore. I hate xperia. I spend a lot of money for this produckt and i got ps4 psp psvita but because of this phone i am not sure i will buy anything from sony in the future. Example i hate "longue" application and its not able to kill or remove! Or note book with pre installed lots of useless applications. Or walkman with automatic volume reduce with3 beeping its appear any time when i listen my musics. And much more problems..
