Root and Signal Spy no longer work together. If you are currently rooted, make sure you hide root and enable Accessibility services. If you have hidden root and are still having trouble using the dialer codes, please email us to let us know at

Sorry for any trouble and confusion!


Android Q

September 2019 update: With the release of version 2.0, Signal Spy is now compatible with Android Q/10! One known "issue" is with the Location Permission setting and an "Unknown SSID" error. Read more about it and how to fix it here.

We have been alerted to issues with Signal Spy and dialer codes in general on Android Q. 

We are going to be looking into it and will update this thread with information as soon as we have it.

Thank you,

Signal Spy Dev Team

Data Usage

Recently we have had several people let us know that they are having trouble with accessing the data usage information in Signal Spy. At this time, we think it may have something to do with an Android update and not Signal Spy. That said, we are looking in to the problem and will have a fix for you soon.

We will keep you updated via this News page, so please subscribe to get updates as they are posted.

Thank you for using Signal Spy!
