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!

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.
Hi Karen. Truly feel sorry about any inconvenience you may be experiencing. You may try the same and check if this works for you!
In case the issue persists, please contact Abbott’s support.
I applied the first libre 2 sensor with no problems, the sensor worked just fine for the first 14 days. When I attempted to reapply the second sensor I found that applicator will not reach the second sensor in the plastic holder. I called customer service and they seemed just as puzzled as I did and I was sent another kit with one applicator and two sensors and the same thing happened! Am I doing something wrong?

l’application FreeStyle Libre 2 sur mon iphone ne veut pas scanner mon nouveau capteur posé ce matin.
la réinitialisation de l’application contient l’option “paramètres” mais, choisie, elle ne contient pas l’option “réinitialiser les paramètres”, donc pas de bouton “oui” pour confirmer, donc pas de réinitialisation possible. Que faire ?
Nous utilisons actuellement un outil de traduction pour vous aider ici. Veuillez éviter toute erreur.
L’application FreeStyle Libre 2 est actuellement conçue pour fonctionner sur Apple iOS ou Google Android OS avec un smartphone compatible doté d’un matériel de communication en champ proche (NFC), requis pour scanner le capteur, et d’une fonctionnalité Bluetooth Low Energy (BLE), qui est nécessaire pour recevoir les alarmes.
Assurez-vous d’abord que votre NFC est activé.
Voici comment activer NFC, s’il est désactivé pour le moment ;
Étape 1 : Si vous possédez un iPhone 8 ou un iPhone 7, faites glisser votre doigt depuis le bas de l’écran pour ouvrir le Centre de contrôle. Étape 2 : Si vous possédez un iPhone X, faites glisser votre doigt depuis le coin supérieur droit de l’écran pour ouvrir le Centre de contrôle. Étape 3 : Appuyez sur l’icône NFC Tag Reader pour activer NFC.
j’espère que cela aide!. Si vous rencontrez une erreur spécifique, veuillez contacter le service client d’Abbott et il sera mieux placé pour vous aider.
Bonjour. Depuis 15 jours, problèmes des données 0g60 d’écart, voir plus, au tel une personne du service m’a dit que le maxi doit-être de 0g40……Que faire ?
Bonjour. Ceci est un message traduit, alors s’il vous plaît, toute erreur repérée.
Veuillez noter que la valeur MARD (Mean Absolute Relative Difference) doit être de 10 % ou moins.
Les valeurs que vous avez partagées montrent une différence significative, ce qui ne devrait pas être le cas.
Veuillez vous assurer que vous n’exercez pas de pression sur votre capteur. Peut-être que changer le capteur et essayer le capteur dans un endroit différent serait utile.
I’ve used the libre 2
first time it was hugely accurate very impressed so I decided opt for libre 2 instead of Dexcom , The second time it kept saying I’m in hypo mode as it’s connected to my diabetic team they kept ringing me to check if I’m alive , This 3rd now is showing I’m hyper 😂 saying I’m 15.9 mmol ( finger test says 8.3 mmol ) Luckily I haven’t taken what libre says as gospel have instead used it as a guide but it’s not accurate and you got be careful and just do the finger blood test as per normal , I will give it a month and do x2 more sensor plus ones ( that just means that it’s a 15 day one provided via health service ) If keep getting stressful readings aka non accurate I probably will switch to Dexcom but the first one which was a trial ones was magnificent thereafter the paid ones have not been good at all …. Thanks 🙏
Hello Raaj. Glad to hear that you did what we usually guide CGM users. Whenever you feel the readings are going wrong, it’s good to do the fingerstick test. And we feel sorry to hear about any inconvenience you may have experienced.
Rest, in case you are planning to change your CGM, you will find this blog useful; https://cgmmonitors.com/freestyle-libre-3-vs-dexcom-g6/
Moreover, please avoid the place where there are high chances of compression, as this results in incorrect readings sometimes. Hope this helps!
Bij ons geeft de scanner aan dat de sensor verlopen is. Dat klopt niet; de sensor gaat nog een week mee en we kunnen hem nog gewoon uitlezen met de app op de telefoon. Het punt is nu dat de alarmen het niet meer doen. Die lopen via de scanner en de scanner heeft dus de sensor al afgeschreven. Hoe kunnen we de verbinding tussen sensor en scanner weer herstellen? De sensor is best duur en als we een werkende sensor vervangen moeten we zelf een nieuwe aanschaffen.

I’ve been using on a minor for 3 months. Both my husband and I have been able to scan from each of our phones. Now we got a new one yesterday and my husband could get it to read, but I couldn’t. Said another is in use. We un-installed his and tried mine and mine still says one in use. Now his won’t work either. How do we fix this?

I’m seeing the same thing as PhilW posted about 12 days ago. The instructions on this page https://cgmmonitors.com/how-to-reset-freestyle-libre-2 tell us to press a middle button that doesn’t exist on this model. It only has one button and doesn’t do swiping. Tisk tisk.

Freestyle Libre 2 sensor fell off after 7 days. Put on a new sensor and the reader no longer recognizes it. Called helpline, but the person answering the phone was unintelligible. Finally managed to convey the problem to him. The Freestyle Libre 2 seems to be garbage.
Hi Harpal. We feel sorry to hear about any inconvenience you may have experienced. In such cases you always call Abbott and ask for your sensor replacement.
