UC v4.3.0.99834 is working great with my Lenovo Tab M10 HD (2nd Gen) that has a 10.1" HD screen (1280 x 800 resolution).
Requires Android 6.0 and up.
What's the specs on your Android that's having this issue?

Have you submitted a Support Ticket (see link in my signature)?

I don't use an Android device, but here are two screenshots users have posted. They can not use their devices as they could until they installed the update. And yes, they were asked to contact PreSonus Support. It seems to be necessary to remind users to not install "the latest and greatest" immediately.

Univeral Control 4.3.0 Same issue I use my Ipad mini to mix my IEMs and the stage monitors after this update does not work can we roll this back ?? How do we fix this .. I cant have a Big bleep Ipad on stage the mini was the perfect solution .

IOS 17.4.1 Ipad Mini 6th Gen MK7t3ll/a

I have the same problem

These issues have been reported to PreSonus support.
They are working on a KB article to address it and offer some workarounds for affected Android users.

"PreSonus Supporthas suggested as a workaround to download the previous version of UC-Surface from Presonus Legacy software page and disable Google Play auto-update. The previous version is working as expected." (Quote from a Facebook group)

The idea sounds good, just that there is no "Previous version" available anymore. That's why this might be a better idea: A user suggested to find the "Screen Zoom" option in the Display menu of an Android tablet and make UC fit to the screen.

There is no workaround for iOS users yet.

What’s the problem with giving a direct link to download an apk file without the participation of Google Market and other stores?

Setting the Screen Zoom back to the default setting. (All the way to the left) worked for me..

There are two APK-files available:

* Universal Control Android v4.2.0.96206
* UC Surface Android v3.4.0.61835 (32 or 64 bit)

Here's the KB article that explains what was changed in the latest release and a possible fix or alternate workaround:

It should be added that there is also a problem on the iOS side. iPads "mini" have this problem too and there is no solution or workaround yet. It was said that PreSonus is "aware of the issue".
