that does nothing with the p80 and is also taken care of with the latest firmware updates when installed to tubo duals, no units should freeze when batteries are insert.
"long fire protection" displays when the timer runs out. you can set it in menu>vaping>timer. it is set to 5minutes (300seconds) by default and can be increased to 15minutes.
(
@GoldenBud think you are mixing this firmware with other stock software or other mods, it has always been more than 10seconds)
it sounds to me like your unit is running quite hot now if you can clear a load in a few draws at 350degrees. its interesting as i used this unit quite a few times with the set resistance but good thing is everyone can dial it in to their liking. btw you can still store the pick inside the prototype unit, it will rattle a bit. apart from that it is on par with all others.
