After 7 months of beta testing, an updated version of SignalCheck Pro has finally been released! Version 4.68 is now live on Google Play for all users. It includes tons of bugfixes, significant 5G-NR improvements, and other things that will make your day better. The full changelog is available at https://signalcheck.app/change-log.
Please feel free to post here or reach out with any questions. I appreciate everyone's support (and patience), thank you!
Sorry, I missed this post earlier -- most mobile providers are now displaying a "5G" logo in the system bar when you are connected to a site that has 5G-NR capabilities, but it does not mean that you have an active 5G-NR connection. It's very misleading, but it seems like all of the major companies are doing it now. I looked at your reports, nothing indicates that you had a whiff of 5G at the time. Keep hunting..
