And i rooted my tablet. And change the DPI from 160 to 130.. After that I reboot and it was stock on Lenovo Logo for 15mns.. And so i guess I failed.. Anyone can help me please?

Hi, And i bought Lenvo Tab2 A7-30GC.. And an hour later. I found out that theres a problem about the sensitivity touch screen.. Sometimes its not responsive.
Figure it out while playing Online Games.. While typing etc..

Is there a way to increase it? Im totatlly noob about this.. Please help.


Btw, I just finished rooting it using KingoRoot...
