There's already been some discussion about updates on the forum, and we absolutely understand how frustrating it can be to have to wait for your update while others have received theirs.
As explained in our FAQ, Google's monthly Security Patches have specific hardware dependencies. We always need to ensure your phone is fully supported before we can test and release them to the operator. Once the quality has been assured (by us as well as your operator), the Security Patch will be delivered to your phone. Due to this, it can sometimes take a little longer, depending on your device model, operator as well as your location.
Hope this helps, thanks for your continued patience.
Have a great day!
