I wish that I could offer better advice but here is a link that will hopefully be of some use...

Hi , i appreciate your suggestion, and i tested various combinations in the manifest file.
From what i understand, this mainly focuses on colors, and does not do the total makeover i would like to see. (which was OK on my (older) samsung.)
It must be something fundamental with the rendering of the controls, because they do work , but texboxes and spinners have become sort of transparent.
The biggest change is in the seekbars, instead of a button-like appearance they look like a movable unframed radio button .
And also the msgbox(2) is totally different, with even a change of order of the "answers".
Is it a "lollipop thing ?"
I am currently using this in the manifest:
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="19"/>
SetApplicationAttribute(android:theme, "@android:style/Theme.Holo.NoActionBar.Fullscreen")
Oh, and BTW , i also had the idea to change the theme on the Lenovo itself.
I tried the "chat" support. They kept me waiting for 20 minutes, "you are #1 in the queue", and then comes the message:"chat service not available".
So much for support under warranty. I also sent an email... but :-(
