My phone is having some weird problem lately, just wondering anyone having the same problem before...

1) Whatapp - Suddenly automatically press on random key and send message.
2) Games - Suddenly Zoom in and out.
3) Main screen - Suddenly Will scroll up and down.
4) Camera - Suddenly will go setting/bing search.
5) Browsing - Suddenly it go to bing search.
5) Sometimes i cant even press back or home button when the phone is acting strange.

If anything above happen, i just have to lock and unlock again(sometimes need to unlock and lock few times) to use it as normal.

Yeah 950XL seem cool. But gonna check how much it cost to repair 1st. Never thought of buying a new phone since i start use 1520 (the only weakness is lack of apps).
