I just updated my phone last night to Android 7.0 after postponing the update for the past week. Now the phone will not turbocharge at all, it just says charging at the bottom instead of turbo power connected. I checked that the cord is working fine as it turbocharges another Turbo 2 that just updated to Android 7.0 earlier this morning as well. The other phone turbocharges with this charger just fine, but mine will not. I already tried clearing the cache in the settings menu as well as booting in recovery mode to wipe the cache partition, neither of which fixed it.
