AFAIK there was only FlexDroid by William Hemmingsen, which was not further developed: https://community.flexradio.com/flexradio/topics/android-app-c125j42djuoai
It works only if you have started your FlexRadio and SmartSDR. You can tune, select bands
and modes and change some radio settings.
I can send the apk file, if you let me know your mail address (I'm on QRZ.com)

You could build a Node Red interface to the radio and then use the web browser on your Galaxy Tab to control it with.  This would allow controlling basics like frequency, mode, bands etc.  It would not be anything like the iOS app. 

You could also build a radio interface using Touch Portal and control the radio with your Galaxy Tab.  Much like I am doing with my old iPad and Touch Portal.  This requires using other third party apps like FRStack, FRLogger, etc to control parts of the radio.  Again, this would not be anything like the iOS app.

You could also RDP into a computer running SSDR with TeamViewer and control the radio from your Galaxy.  This is the easiest option !

Just some ideas of how to use your Galaxy with your Flex radio.

I'll comment on the RDP. Watch out if you do not have unlimited data on your phone! I did that a while ago before V2 came out and was using 1.1 GB of data an hour!

Splashtop remote has better throughput, cleaner audio and uses less system resources then team-viewer- https://www.splashtop.com/

Excellent question John as I am an Android fan as well. Another workaround albeit clumsily is the use of either teamviewer or anydesk which are remote desktop programs.

The screenshot below is low resolution compared to my tablet screen.  It shows how I operate my complete station remotely, including a Flex 6300, from a Galaxy Tab S2 8.0 In Muti-screen mode.

The top window is Chrome Remote Desktop showing my PC at home. The bottom window is RCForb for Android from the Play store.  It operates the Flex via the free RCForb server running on the same PC at home as is running the radio, rotator, SteppIR and antenna switch.  RCForb also provides two-way audio to and from the radio.  I've hardwired the audio between the PC and radio due to all the trouble with DAX but now that DAX is more stable, it should work as well.  I haven't tried it lately.  Please note, Microsoft Remote Desktop is not suitable as it disrupts the PC's audio drivers.

This same arrangement works perfectly on my Android 6 inch cell phone too.  Although lower density displays will work, a 1080P display is the minimum that I find suitable for good clarity without having to zoom in and out.

You can control the amount of data used by slowing the waterfall and limiting the spectrum refresh rate.  I find that I can get it down to around 600 Kbits/Sec. if necessary.  A good compromise of waterfall speed and data rate is around 1-Mbit/Sec.  Of all the cell carriers, I find that AT&T works best.

I set the RCForb server for the Kenwood command set which works well for the Flex.  The Flex command set spawns dual screen and I could never get rid of it.

You'll have to update your Android to 7.0 for multi-screen.

You can get the RCForb Android client, for your phone or tablet, from the Android Play Store. Extensive documentation, a free Windows remote client and the server, which is required for your Windows PC at the station, is available at www.remotehams.com.
