Sorry to hear about the reduced performance! For auto-unlock, if you're noticing the "welcome back" signal, then the issue keeping auto-unlock from triggering properly is the connection between your phone and Sesame. You can try unlocking your screen to speed up the connection. Most device manufacturers set their devices to be "at rest" when the screen is locked, and there is reduced function when the screen is locked. Unlocking the screen will help your phone connect to Sesame's Bluetooth signal more quickly.
It can also help to unpair/repair your Sesame in your device's Bluetooth settings, reset your network settings, or restart your phone to get the connection up to speed again. It's also a good idea to turn off battery saving settings for the Sesame app so the app can request more frequent Bluetooth scans. We also do recommend removing/replacing the batteries as it causes Sesame to reboot.
Please give our tips a try and hopefully the performance will improve! - CANDY HOUSE
