Blue Iris

Blue Iris Android App Version 3.0.46 on Android version 13 freezes when connecting to Blue Iris server version 5.9.9.0.

Band Aid:
In Android go to Settings/ Apps/ Blue Iris/ Storage then Clear Cache & Clear Data followed by rebuild of Edit Login produces restored functionality.

Note: This problem does not happen on Android version 11.

Note: The server does not freeze. The Android App freezes.

Note: I am not British. When I try to change that at signup it kicks me out of the registration process.
Note: I am not in UTC-4 time zone. When I try to change that at signup it kicks me out of the registration process.

Some people I respect very much recommend BI software. I'm in the testing phase. I like it. But there are threads on here from years ago about this very problem and it goes unanswered. These guys can't (or chose not to) build a forums registration page that doesn't crash when you simply click a drop down. Really thinking hard about investing in them. And I don't mean the $100 or whatever it is for the software. I'm talking about all the work and infrastructure to build a system that I'm going to rely on when I need it most. We'll start out with about 10 cameras and give that a shot. If this cell phone App keeps freezing that's likely to be a deal breaker. Too bad. Looks like nice software.

I've got Android 13 and 14 mobile phones that work fine with the app. I'm running BI5.9.9.0 and Android app 3.0.46. It also works fine on a Fire HD 10, and two other tablets of different ages.
From that limited analysis, I will leap to the conclusion that there is something amiss at your end

Seriously though, is this mobile device suffering from limited memory ? Can the mobile device see BI5 using UI3 in a browser ?

As for the forum, BI5 is in the USA so that is just weird.

Please note that this is a peer to peer forum. We will help if we can, otherwise we will advise you to contact Support. That is why you may have seen old unanswered queries. When it gets really bad, I ask Ken (The Boss) for a response.

What's odd is it's a brand new phone.
There's really nothing on it but maybe BI and 2 other Apps.

One thing we did is configure the server to not send Notifications on all the alerts.

This way I only get Notifications when nefarious things are happening!

Same problem here on latest android build. Lag after enough alerts build. Mobile app becomes unusable. After clearing alerts and restarting the app clears it for a day or so then its back to unusable yet.
