This topic is about smartphones tested with software of actual version, 1.0 now.

Successful:

Sony Xperia Z - best results
HTC One Mini
Alcatel One Touch Pixi 3 - unexpectedly good for their price
Nexus 5
YotaPhone 2
Leagoo Lead 3 - has strong high-pass filter and noise, but allows to obtain spectra

Unsuccessful:

Samsung Galaxy Star Advance, Lenovo S850 - both have uncontrollable AGC (automatic gain control), the gain take on a new value each 1-2 sec depending on input signal. Final spectrum looks like superposition of several spectra with different gain value. The dispersion of the gain value is 25% approximately.

My phone has died, and I will be looking for a replacement. My old phone, a Samsung SM-J320A, barely worked - I could tell that the sensor was picking up, but it wasn't working right and the peaks were weak at best (barely above the noise). The reading I've done is that the model has built-in digital noise cancellation on the headset mike input and that it cannot be changed. I would put the Samsung SM J320A in the unsuccessful column.

I need a GSM phone that will run AtomSpectra, has OTG, and isn't tied to a single carrier - any suggestions? (I've made a list of the phones that have been listed so far.)

Thanks!
