This app has been great over the years as a Fi user, and I've found it a little easier to use than some of the others I've tried. I'd love to see a few more details about the connection strength in the app, tho, and it would be nice if it showed info about the Pixel series' Dual Connect capability. Also, unfortunately, I'm not sure how much longer it's useful without 5G support or now that Sprint has been fully merged into T-Mobile and I'm not switching between networks any more...

Hi Billy - thanks for being a loyal user! An update/upgrade is currently in the works that will include 5G support. Please stay tuned!

What's the point? It used to show the network Information in the notification, along with a matching icon. Now it just says upgrade to pro. Home screen is the same. Seems they completely removed the useful stuff. This is yet another example of a nice independently developed app being acquired by a big box mobile app company and being destroyed as a result.

Hi Gregory. Sorry to hear you're having trouble with the app but Signal Spy ownership and development haven't changed.There are a few different things that could be causing the trouble you're having, so please email us directly at support@signalspy.com and I'll be happy to troubleshoot with you! Thanks.

This app is essentially broken. Will not invoke dialer codes manually via the clipboard, and does not automatically bring up the dialer and insert appropriate codes when that setting is turned on in accessability settings. Uninstalled and reinstalled, I was able to get it to function properly just once. After that, simply non-responsive. Device is a Pixel 4XL.
