Hi ECF I've been vaping for quite some time now and been using ECF for a lot so I thought I'd sign up. Anyway, I have my Cana dna 30 clone (18650 version, running a .3 sleeper build on 24g gplat.) out of the box about a week ago. So far it works great except for one glaring issue... About two days ago I got home from work turned it on to see the screen wasn't turning on, yet it fired. So there is absolutely no display at all. Just to clarify it is NOT in stealth mode because the battery is not showing as well as any of the lock or message screens. So randomly the display comes and goes now. It's very upsetting because I really like this mod and it still works well but now I have like no idea when my battery is going to go etc. Has anyone had this issue or dealt with this problem? Thank you so much for any help or advice given!
