1st timer here. Has this lockscreen issue been resolved? I’m on v1.5_20201210.
The optomization setting is for a different, 2nd lock screen. Search settings doesn’t reveal the security option to disable lock screen. Thought I’d check in @pawgol and see if you ended up needed to do a factory reset? Cheers.
I didn’t do factory reset yet. I ended up getting used to this lock screen. I’m also still running on older version 1.4_20201031 (my KP2 doesn’t detect any new firmware).
Try this and see how it goes
Thanks for the update. Seems a new firmware is available to flash, so I might give that a spin. Best wishes to you. Take care.
Upgrade to International FAW Style A10 Firmware allows to turn off the screen lock but it also requires full reset of the watch 
I realize this is years later, but I just came across the exact same problem in this email thread with my KO2. Sadly, I think you are right. With looking around for hours, the only thing that worked was a factory reset. It’s unfortunate there isn’t a way even with getting into root to make this fix (perhaps there is, but I couldn’t find it).
