Phone laggy

[APURBO DEY]

Hello. My phone model is oppo a5s cph 1909.It is almost 3 years old. It's display gives issues ( if I tap on a place, sometimes it taps at any other place. Sometimes it ghost touches and sometimes doesn't respond).It was on the drawers for a month because it's display was damaged.then recently it had been repaired. But after day of repairing I had seen the display problems mentioned above. Then I freed up phone space and ram by deleting some apps and the problem seems to be better at now though it is still present. So can anybody give some cures?
Thanks to all who read it and sorry for wrong English.

It sounds like a damaged or defective digitizer. Take your device back to the repair center; they should have given you a warranty on the repairs.

What is a digitizer? And after I had done what they told ( basically free up the space and make the phone lighter), the phone is now better. And can u give me any recommendations for making the phone faster without root or custom ROM? Thanks anyways.

The digitizer is the electronic part of the screen that detects touches.

Return phone to repair center and demand them to fix your screen issue: they obviously performed miserable service - you even have paid for?

The phone seems to be better each day. But I don't understand how is that. And power button issue is also less now.
