I'm not exactly sure of the reason yet.. there were no issues until I started "targeting" Android 10 in my compiler. I had not changed the core functionality of the app, so it must be something that changed in the way Android 10 behaves. Unfortunately, as you have experienced, I have not found a perfect solution yet. The solution I implemented in the most recent update apparently fixes it for some users, but not all. Complicating things further is that I do not experience the problem at all on my Pixel 3 or Pixel 4, and there are no error messages being logged by any devices -- it's just not updating. Oddly, if you launch another similar app (like Cellmapper), SignalCheck starts updating regularly. I am stumped so far!
Okay now after going back into a small town in rural mo where I go on the weekend a lot i am able to connect to b71 again. First time I’ve been on b71 around here in over a year.
One question.Is there anyway to see how wide the the LTE channels are on an iPhone?
