I have a problem with the scanner on a Huawei Tag-L13 When the app opens and they scan a Qr code it does everything right, that is, it opens the camera, reads the QR and shows its value, however when they give it back and wish to scan again it does not do it the screen is blank , and you have to close and open the app to scan again, the logcat shows the following:

pd: I noticed that at the time of opening the app a second app called KingRoot was opened, I do not know if this has something to do with the problem ....
