Statement regarding support for CTEK CS ONE and Battery Sense apps on Android 13 OS

We regret to inform our valued customers that the current issue regarding the pairing of CTEK products with some handsets using the Android 13 platform cannot be resolved through immediate fixes. 

Within the Android 13 update, changes have been made to the new BLE (Bluetooth Low Energy) stack vs the previous versions for manufacturers like Samsung, One Plus, etc who now must implement the new stack in their phones. This has caused several problems for companies like us with Bluetooth dependency.

Additionally, NRF and other 3rd party Bluetooth apps are experiencing the same/similar issues connecting on Android 13. Unfortunately, reproducibility of the issue is sporadic, with far too many permutations of phones and manufacturers.

Google have released updates, however there is no market indication that this has resolved the issues, for which the onus still lays with the individual manufacturers. It is also noted that Google’s Operating System update has been released as a patch that remedies for some manufactures on some OS versions, and not for others.

We want to assure you that our team, along with Android and Google are actively working on finding a solution, which we are hoping will include the patches to fix the issues in Android 14. In the meantime, we kindly ask you to stay tuned for future firmware and patch updates for your phone.

Please however, contact us at support@ctek.com where we will help try to troubleshoot the issues you are experiencing.

Thank you for your patience.
