Scanning issue

Hello.

Three days ago everything seemed normal. The sensor was working fine and everything until I tried to scan it around 9pm. It was like the sensor was not detected by the phone,nothing at all. Then I saw that the sensor had fallen off and was hanging off so I changed it. The new one had the exact same problem with the scanning. I pressed the scan button and hovered the phone over the sensor but nothing happened. Just a few "Sensor errors now and then" and it said that it was still connected to the one that fell off. It's impossible to activate the new one since it does not even get detected. Contacted abbott and they told me to reset and restart the phone and reinstall the app which I have several times. Still nothing has worked. Today I tried to scan with another phone and it worked instantly but not with mine...
