A tweak in a file albeit remove it, however completely remove the palm rejection function ! so that is even worse...
Anyways long story short....
the pointer cursor could be found inside system/ framework/ framework-res.apk ... now wait... you cant simply open up the framework-res.apk ! Only way to do so, is to get it pulled by adb , or with root explorer in a rooted phone. I used Es file explorer, mounted System as RW and copied the frame-res.apk to the desktop.
Then with win rar, i opened the frame-res.apk, located the pointer icons inside , res/drawable xxhdpi folder and res/drawable xhdpi folder. the name of the files are pointer_arrow.png. I made a pointer in photoshop with only 10 *16 pixel maybe and just a dot . then renamed the file as pointed_arrow.png and replaced the original .
Now close win rar... and copy it to phone system folder.
Now the important part... dont directly copy the modified framework-res.apk in system/framework directory. doing so will cause bootloop !!
Just selet the modified file , check properties and change permission . Like this
.. now copy and replace the original framework-res.apk with this one . Reboot your device and pull out your spen and draw near the screen.
Congratulations...you are black arrow BUG free
