Doubt with the app and the sensor

Hello everyone, I have changed my mobile and I have a problem, with the previous one I could scan the sensor from any application without having the need to have open freekHave the OPP Open, I have looked at the settings and I haven't found anything.
Something similar has happened to someone ever ????Thank you!!!

It has happened to me the same since the last Android update.In fact, I put a post asking a few days ago.

Oh go, then then is that, of the update, and they have not told you anything nobody right?

Well no.I do not understand if we are the only ones to have this problem

I use iPhone and I have to open the application and click "scan" to read.When I used Android, he scanned directly without opening the app

Well, it doesn't leave me anymore.I have to enter the app yes or if
