Since my last message I successfully installed the SDRplay Android driver on this:
http://www.gearbest.com/tv-box-mini-pc/ ... html?wid=3
This device also allows the use of SDRplay when booting Win 10
One tip I found useful ,being new to Android, is using "Total Commander" to
clone an installed application from an Android device to another.
On one panel you select "installed applications" it shows a list :"///Apps"
On the second panel you select an empty directory "/sdcard /Download" in my case
Back on the first panel you select the application you want to copy by clicking on it's icon
"SDRplay driver 0.1" for example (and SDR Touch Key 1.03)
You click on the copy icon (second from left on the bottom bar) and you get a nice
"SDRplay driver 0.1.apk" 1.3M file in your empty directory
This worked nicely for me but I must say that all the Android devices I tried were registered to me.
Most were AC powered with a fair amount of USB ports allowing the use of keyboard and mouse.
IF filters in SDR Touch are less sharper than in other applications so it is often better to use
too narrow ones.
One good idea for RTL devices on tablets would be to use the IR remote if supported.
May be it would be nice too to add an IR receiver to future SDRplay SDR.
