Hello, I own the SMOK Infinix for more than 3 months now. I change the cotton myself for the pod and started having issues with the device. After 2 months it would fire a while after pulling. Fixed by cleaning the inside of the device and removing the paper cover on the sensor. Worked perfectly. Now, few days ago, I noticed I had to pull harder for the device to activate. And now, literally an hour ago it would stop pulling. Isolated the airflow for a tighter pull worked for couple of minutes, now it just stopped. After some blows from the charging port it would do the infinite firing bug and that's the only way I can get a hit. Please help. P.s I did clean the inside of the device again as much as I could. It gets a really good connection, just won't fire.
