  1. Senor fell off only did one test put new sensor on it won’t read the new one

  2. My previous freestyle libre 2 fell off on Tuesday June 18 I called the help desk and they said that they will send me a new one! On Wednesday June 19 I put in a new sensor and it told me ready to scan in an hour! Every time I try to scan the new sensor it tells me to replace with a new one! I tried to call the help line but it was too late! That’s 2 sensors that don’t work? I have been using the freestyle libre for months now these 2 last ones do not work? My phone number is +18054691865 my name is albert

    1. Hello Albert. We feel sorry about any inconvenience you may have experienced. We would recommend you to please try calling the Abbott’s helpline again and they would probably send you a replacement. In the meantime, we are also looking into this for you and will let you know if an accurate solution comes up. Thank you!

    2. Could you please try the following and let us know if this works for you;

      Restart your phone > go to ‘Settings’ > Switch Bluetooth off > Switch Bluetooth on

      Once done, put on the new sensor, scan it and start after an hour.

  3. I am having the same problem with sensor not reading. I now have 2 sensors that will not work. If I try your recommendation will I lose another sensor? Funny that these are all happening at the same time.

    1. Hi Karen. Truly feel sorry about any inconvenience you may be experiencing. You may try the same and check if this works for you!
