My Samsung Galaxy A53 5G updated from Android 12 to Android 13 sometime in November 2022/early December 2022.
I have a piece of medical software on my A53 called Freestyle LibreLink.
Freestyle Librelink is supposed to receive Bluetooth Low Energy signals from a Freestyle Libre 2 sensor attached to my arm and trigger an alarm on my A53 when my blood glucose has gone too low, or too high.
Both the Freestyle LibreLink app and Freestyle Libre 2 sensors are made by Abbott Laboratories.
Since the update on my A53 from Android 12 to Android 13 I no longer receive low or high glucose alarms.
The update of my A53 from OS 12 to OS 13 also coincided with the manufacturer of the Freestyle LibreLink app updating the LibreLink app twice: the first time on or around 15 November 2022 and the second time around 1 December 2022.
This failure to receive low and high glucose alarms can be very dangerous.
The Internet suggests the issue of Android phones with OS 13 having the Freestyle LibreLink app on such phones not being able to receive low and high glucose alarms was known about and reported on Google's Issue Tracker as early as August 2022.
Clearly the issue has still not been fixed yet.
Abbott Laboratories's customer services have suggested every possible permutation to try to resolve the failure of low and high glucose alarms on my A53 (checking all app permissions are granted, including overriding "do not disturb"; clearing cache of Freestyle LibreLink; force stopping and restarting Freestyle LibreLink; uninstalling and reinstalling Freestyle LibreLink; switching Bluetooth off and on; switching A53 off and on).
No solution suggested by Abbott Laboratories has resolved the issue of no low/high glucose alarms permanently, only temporarily and only for a few hours at best.
The Internet also suggests that this problem may be unique to Samsung mobiles (although I have read that it has affected dome Google Pixel mobiles as well as iPhones).
Does anyone know when the issues with Android 13 disrupting Bluetooth Low Energy signals stopping high and low glucose alarms being received and given off via Abbott Laboratories's Freestyle LibreLink app on Android phones, (and my Samsung Galaxy A53 5G specifically) will be resolved permanently?
