Is your issue same as QC#119476 ?

>   Samsung Tab 3 7"
With my 'Ainol Novo 10 Hero II', one Button FireMonkey app starts, but it shows only Gray screen...
In fact, both devices are using same minor GPU, 'Vivante GC1000+'. and, the GPU seems to have some issues about compatibility of OpenGL or so...

My issue is that according to the requirements listed by EMBT this device should be supported. However, it is not supported, and the reason is not exactly clear. So, in a matter which device will be supported and which will not be we need something more reliable than the wild guess.

Same problem with my old tablet. It has Vivante GC400.

We know that Japanese docomo dtab also has same problem.

The SoC is HiSilicon K3V2T + Vivante GC4000.

This issue will be fixed in the future(e.g., next update release or so).

Same here. I have installed XE5 update 1, but problem remains the same.

FireMonkey does not support Samsung Tab 3 7'(SM-T210R) Processor: ARM Cortex A9, with NEON as per specification; OS: Android 4.1.2

Great news! After installing update 2, FMX apps run fine on Samsung SM-T10R. I presume a fix on the android libs for the device GPU.

Thanks Embarcadero...

This issue should be fixed with XE5 Update2.
