Show Touches is an option in Developer Options. Do you have them enabled?

I may have misunderstood. It's not the Show Touches that's worrying you?

Yep my problem is when an app is not responding and taking too long to respond and i press the multi tasking key & end all the tasks.. black screen will show up.. and i cant even install an app (newly reformated).

I've seen in some of your posts that your phone is getting hot sometimes and the battery is having some problems as well. Have you already tried replacing it for a new one? It's possible that all your issues are related to a failing battery.

Check in your battery stats if any app or process is taking an unusual high percentage. Do you use a SD card? If so, have you moved any app to the card?

And, as Belodion said, why did you enable those developer options? I'd switch them off for now, I don't think they are very helpful to find a fix for your problems.

Maybe the same apps that are giving you problems?

 

[belodion]

Try Unmounting and Removing the SD card.
Tell us if that makes a difference.
If not, we'll go on from there.

First move those apps back to internal storage. If you remove the card first, you're removing the moved apps.

Is the battery a good one, or one of poor quality?

Also, was there anything that you did that has fixed the main problem?

I try the original battery and the low quality battery . Still getting hot faster.. Why my sd card is related to my problem??

To answer your question above, and in the thread you started elsewhere:
SD cards can be troublesome.

It's difficult to know for sure but there's a big chance that all your problems are caused by a failing or bad quality card. As Belodion said, SD cards can be troublesome, specially if you move apps in there. Do as Rukbat said and, in the future, try using the SD card just for media files (pictures, videos, music).

You could try formatting the card and see how it goes, but if it's an old, slow or bad quality card I'd recommend you to get a new one.
