Yes, I too believe it's a chip issue. The smok brand is readily available, cheap and cheerfully innovative most everywhere but are known to have qc issues. I'd return it for a replacement. Btw are you a new vaper and this is your first starter kit? If so, I would recommend an heir to your analoges and a spare. Plus a third tank and spare coil heads that you keep for craving emergencies in the next highest strength nic to what you find is working in your preferred flavour, ask for a double flavour shot if you can in that higher strength. If for whatever reason you are going nuts for a cig switch your toppers and vape exhaling through your nose for 10-15 minutes. Savor that yummy juice! Then re asses and if you still want a cigarette have one, make sure it is not your usual brand. Pretty quick you should find you don't really want or enjoy the stinkies! If not, come back here and ask for other ideas...tons of helpful folks here have found as many ways to successfully quit smoking as there is different devices and juice flavours. Someone has come before you and found a way that works for them, and there IS a way that will work just for you too!
Vape happy, and vape on!
