I have had the smok xcube 2 for 5 months now and suddenly its started to act weird on me, when i press the button to vape instead of vaping it keeps changing the strength. It has also been changing the wattage by its self its just keeps increasing to the max and when i go to turn it down the button just keeps turning bluetooth on and off. does anymore what is wrong with the mod i tried doing a firmware update and it did nothing.
