Sliding two fingers on the screen causes jitter.

Zen Master I
Rooted: No
APP Name: All applications that require two simultaneous touches to control.
Model: ZE620KL
Firmware/APP Version: Tested on several.
Frequency of Occurrence: Every time the user uses two fingers on the screen.

Hello, folks. I bought my Zenfone 5Z (4GB/64GB) recently, specifically to play some games that other devices that were within my budget wouldn't be able to handle. But I'm disappointed with a detail that, although it looks small, makes a huge difference to the gaming experience. Every time a game requires two fingers to control (usually first-person and third-person shooting games), the touch sensitivity doesn't allow me the precision I need for such games. I slide my left thumb on the left side of the screen to control the movement and my right thumb on the right side of the screen to control the aim, as the game requires. The problem appears when I try to aim while running. What you don't notice when you slide your fingers quickly, when I slide slowly (for greater accuracy) the screen doesn't respond as it should, generating a jittery stutter. To test more thoroughly, I downloaded the MultiTouch Tester app from Google Play. During the tests I was able to see that the problem happens when - specifically - two fingers are used. Not with one, not with three or more. I'm in the stable version of Android 10 that I downloaded from the official Asus website in my country. I was only able to update my device this way, since when it arrived (with Android 😎 I couldn't find firmware updates available. Anyway, I found this problem even when I was using the Android version that came from the factory on the device. Thanks in advance!

The battery led doesn't change to green when fully charged if the phone is charging while turned off. Battery drain is two times worse than the first Android 10 Stable, and ten times worse than Android 9. The volume controls under setting are glitching. All the system is stuttering like an Xiaomi's intermediate device. The touch panel is presenting a low DPI mouse behavior, getting worse while more fingers are touching at the same time. It causes the impossibility of having a flagship gaming experience, like it's better to play on ZenFone 5 than in 5Z (and it's really is, video proof by JonathanSR some replies above).

I've sent the phone to a service center in this weekend, but they've returned it saying it wasn't a hardware issue. It's a recent bought device (2020/02). At least here, the battery drain is fine (compared to what Bruno~xD has said). Let's hope this problem can be solved soon.
