Why won't the screen of Samsung Galaxy Ace work correctly?

My samsung galaxy ace gt s5830 touchscreen is not working correctly.I have changed the touch screen digitizer, I have installed the firmware android a few times and even installed android 4.2.2 but still not working correctly.It doesn't always react when I touch it.Can you please tell me any solution to my problem or I just have to buy a new phone.Thanks in advance!




Hmm.. Have you tried using touch sensitivity apps? Please try some as this may fix your problem. Or as to what you last said above, I think you should buy a new phone.
