ZUK Z2 Pro. No Touchscreen - Lenovo Zuk Z2 Pro Questions & Answers

Hi,
I've tested 3 7.x Roms on my Z2 Pro (z2121). But none of them have a working touchscreen.
Does anyone knows a fix or a reason for that problem?
Greetinx,
Fro-He

Huawei P9 Touch Sensitivity

This is my first smart phone from Huawei
Previously used Sony Xperia devises :good:
My problem is I feels like there is some problem in touch sensitivity
I checked the whole touch screen with Developer tools and it works perfectly :good:
Tried the glove mode
But still it feels like the touch screen is not as smooth as sony phones
sometimes or most of the times i have to press twice to get the work done
Is this problem only limited to my P9?
Please share your ideas
Thanks
It feels great on mine, better than the OP3.
that's good to hear

It's software related. On nougat works much better on my p9. I switched to p9 from Nexus 5 (after N5 xiaomi mi4 for month) and both have better touchscreen sensitivity, but check this. Open photo or something, apk to test screen and screen will work great. It have delay on emui ui like in settings when you want to click something too fast.

yes i also thinks this is software related since touch screen works flawlessly
couldnt find any defect in touch panel
for example if i go in to the settings and try to go inside/open something from there i need 2 touches sometimes
hope this will be ok in nougat
thanks for the feedback mate
cheers

Hi Joiner22,
I had the same problem with my phone (ZUI 2.0.048 ST, Android 6.0.1).
Since I upgraded to (ZUI 2.5.355 ST, Android 7.0) the problem was solved

I did a test with the newest stock and custom rom. But the problem persists.
I have this problem since at least a year and it seems to be a really common issue with the Zuk Z2 Pro.
It has something to do with the autofocus component, so it is primarily a hardware issue. The only workaround I have, is, to shake the phone when the camera app is open, so it tries to refocus. (while shaking it might be possible that you here some loose parts in the camera)
Hope that helps and yes it is really annoying.

Yes, it was exactly like that but as I said, after upgrading one week ago to ZUI 2.5.355 ST, this problem was solved. If it comes back, I will say something
I changed the rom and it did not work. I had to buy a new camera module on AliExpress.

Problem with gyroscope

Hi, i have problem with gyroscope on my p30 pro android 10.When i use "Lg Webos Magic Remote" app there are lags with pointer on tv about 0.5 sec. I used it on Oneplus 6T and it was working smoothly. I've tried this app on my wife's P20 pro and it is the same lags. Any suggestions?
If the 'problem' exists on both your P30 Pro and your wife's P20 Pro, what makes you think its a faulty gyroscope on your phone?
I was reading about some people problems in pubg game on huawei phones - people had lags in game.
"So i switched from galaxy a7 2018 to huawei p smart an i noticed that gyroscope on huawei is really delayed and slow in pubg mobile and anything else related to gyroscope so does anybody know how to fix that because things like playing games with gyroscope or watching vr is really bad expirience."
As i said before i didnt have anything like that on oneplus 6t it was also on android 10. Experience was like i would use orginal magic remote from lg. So somethong has to be related with huawei devices.
