Comments on Robot36 - SSTV Image Decoder for Android

Pretty Awesome sstv decoder that you would encode random images you already have on your desktop or something then just decode it over whatever speaker you have just to see the result then over time forget about the app, but that's just me but still pretty good decoder app and gets the job done

Hey Ahmet, this app works really well at decoding, and that's without using a HAM radio and just playing back SSTV audio from YouTube. One note, and this doesn't affect the rating: it seems like Scottie DX peaks out the microphone and causes the app to switch to RAW for second intervals, which causes cyan-line artifacting that prevents images in that format from saving. Not your fault though, just a side effect of my mic being just OK. Everything else works great though!

Extremely cool works very well. If you are simply using your phone's microphones to decode SSTV images from what I found I would recommend you set your sample rate to the highest it will go, you just leave the channel select at default. Change your audio source to unprocessed and leave your audio format as floating point

App sucks. Buggy as can be. Barely functions half the time. No deciphering between locked mode or Auto select mode, I can literally play SS TV signals right next to it, and it will not pick up anything. There used to be a good app on here, but now we're left with this one.

This app is awful! It does NOT run in the background like advertised. No matter what mode I use, I get gibberish. Yes, even when I try audio mode! Terrible!

Worst one I've seen yet. Doesn't decode, doesn't restart at the top. I'm receiving very strong clear signal but this app can't decode a clear image in any mode.....

App doesn't work since update, it wasn't exactly "great" before, but since updating, it doesn't decode ANYTHING 🤷 old version was deeply flawed, but better than new version 🧐 SSTV Decoders are no good unless there's a WORKING Auto mode, we never know what mode is being sent, by the time you go through them all, the message is over 🤦
