Android Drawing Tools

[chipsm]

I know that I posted a question about the eraser tool in the Android O/S. Now I am asking a more general question that should also include Apple mobile devices also.
The eraser isn't the only tool on ANdroid that seems to be not working. I must ask if anyone has seen the same deficiencies on the the Apple Devices also.
I am interested in hearing from other people if they have tried and either succeeded or failed in applying all or any of the drawing tools on either platform.

If you have had successes, can you provided samples.
If you have had failures, can you please document them for possible bug reports.

Thanks.

You certainly don't mean _drawing_ tools but _PAINT_ tools.
Related to paint tools there are already some 'newer' bug reports, for example #17969 and #16222.
