Hi,

Teclast T30 has a good hardware, but some reviewers say it has a bad touch sensitivity and a high touchscreen lag.
Are there any owners who can confirm the problem? Did the updates improve it?

Thank you!

It does have couple screen issues:
-slow screen refresh rate
-poor touch sensitivity
Flashing firmware somehow improves the performance.

Mine has come today with an ID T1P3 and fimware v1.01_20190906

How can I check low refresh rate and touch sensitivity ?

Please install Touch Multitest and Screeninfo apps and share the values you are getting.

1. Touch Multitest - my average touch samples per second is 40. In my huawei phone im getting 180.

2. ScreenInfo - refresh rate is around 53.65 fps. Almost all phones are 60fps.

3. You can also use any drawing app like ibis and see if ink is lagging as you draw.

I have exactly the same values as you.
40 samples per second and 53.64 fps BUT I can't feel any real issue in real world use.
I haven't installed any drawing app or any other demanding app, but scrolling down or app using a web browser and typing here for XDA forum using Tapatalk is flawless and accurate.

The tablet is really fast and after using it for just a few hours, I can't feel or see a real issue.

Good to know there are no issues with your unit as I also got a T1P3 fw v1.04_20191108. probably just a software issue that can be fixed by a firmware flash.
Actually for basic use, no issues with touchscreen especially if you are swiping gently. But if you are used to swiping fast like flicking, there will be instances the screen does not respond well due to low sensitivity. and if you will use it for games like Call of Duty, it will not be a good gaming experience.
did you happen to remove the preinstalled screen protector?

Yes, I always do that and I removed also the backplate cover too.

I did not remove the screen protector on my unit. That might be a factor. Will remove it once I have an extra.

@NikosD

Yes I saw your video but I don't know what app to use, in order to try to reproduce it.
I don't want to install drawing apps.
