Phone clicks the screen on its own randomly

My phone clicks the screen on its own randomly that I am unable to press any other button.
Because it touches the screen so fast, even the power button is not working that well at the moment.

I tried turning it off, turn it back on, and reboot but it still does not work.

I have unscrewed the back and removed the battery on my own, so I cannot even get any factory warranty.

Any help would be much appreciated.

Thank you!

What exactly are "Clicks (All)" and "Link Clicks" in Facebook Mobile Install Ads

I have an Facebook Mobile Install Ads, which is used to drive my app installation rate.

My current "Clicks (All)" is significant higher than "Link Clicks".

I had gone through https://www.facebook.com/business/help/674769555983979 & https://www.facebook.com/help/commun...04930247030298, but I still have doubt on it.

My understanding is,

If clicking on ads brings user to Google Play Store,

+ "Link Clicks" count increase by 1
+ "Clicks (All)" count increase by 1

If clicking on ads brings user to my facebook page, or user "likes", "comment" or "share" my ads,

+ "Clicks (All)" count increase by 1

The problem is that, clicking any where in the ads, will only lead me to my Google Play Store page! There is no way to go to place other than Google Play Store page, by clicking on the ads. Also, the count for "likes", "comment" and "share" are 0 too.

So far, I have 2 "Link Clicks" & 60 "Clicks (All)".

If, 2 users go to my Google Play Store page by clicking on the ads, what other 60-2=58 users are doing? Where does the counter for "Clicks (All)" comes from?

Thanks.

Ghost clicks, phantom touches fix?

I don't know if anyone reads this, I'm running cm 12.1 on a c6833 z ultra. Can any one help me lower the screen sensivity? I increased the clearpad.IDC values in system/use.IDC
It didn't help a lot. Same with decreasing them. I tried googling for a solution, but no such luck.

Not running any custom ROM based on cm. Just stock cm.


Thinking about selling the device. I hate phantom clicks.
