Can you please add support for android 4.4

Anyway, thanks for you excellent work.
How can I open 2 different miners with EthControl? I would like to run Ethminer and Claymore at same time or 2 Claymore to different wallet?
PD: I can't install on S3 MINI

Yes you can use two different miners on same machine, just use different folders and set them different rig names. Android 4.4 should be supported, what is the phone giving?
