I'm developing an app for an Android tablet with a NFC reader. I have my app running 24/7, the tablet is specially designed to work as kiosk.

My problem is that sometimes the tablet stop reacting to tags, randomly, sometimes after some days other times after months of running, reading tablet's logs I see the tags are detected by the system, but Android doesn't route the readings in my app. To solve the problem is sufficient put the app in background and re-open it, it isn't necessary killing the app or restart the tablet but those solutions works as well.

I use an AID to route my readings to my app, and the category I declared on Android is "other".

I'm desperate I don't know what to do I've tried all the options but after some time the problem reoccurs
