Android phone/HackRF USB port experience
I have used the SDRTouch and RF analyzer to interface with the RTLSDR ($12
analog TV tuner) and the HackRF. Both of these draw power heavily from the
phone. For the SG3 and SG5 I replaced the stock batteries with heavy duty after
market units available from Amazon. The SG3 had to be rooted to obtain
permission to access the USB port. The SG5 may not have required rooting ... I
forget & do not have current access to an SG35. I was able to access these
radios with both of the above apps on an ASUS Zphone with the micro USB2
interface, no rooting needed .. but the battery is not removable, thus no heavy
duty battery replacement is possible for this phone.
SDRTouch also works with the SdrPlay radio.
I tried to use a newer ASUS Zphone with the micro USB3 interface. This did not
work immediately but I did not spend any more time with it.
In summary, If you want to use an SDR with an Android phone for anything more
extensive than a ¨quick look¨ an SG3 or SG5 with the heavy duty replacement
battery will work well for you.

Ok,
>There is an android app called rf analyzer that will control a hackrf.
William, tanks for the suggestion. I just purchased the RfAnalyzer, it
seems to work on the S7. I was fearing no demodulation(just an
analyzer?) but it works, tested on a couple of repeaters and FM radio.
>I have used this app on an sg3 with >the after market heavy duty battery.
What did you use to inject power? Is there anything readily available? I
hate to mess with USB connector, probably the most unfriendly connector
for DIYers ever.
>The SdrTouch app might also work.
SdrTouch afaik does not support the hackrf.
In any case I am thinking to add a vanilla SDR stick to get full
duplex/double reception, and maybe easier reception with RPI for stuff
like DAB and ADS-B(not clear to me how difficult is to receive them with
a HackRf).
Thanks!
