OK, I've got a VKWorld VK6050S (note the S). This will be a long story, but I feel I must post many details. Otherwise, there will be that smart-*** posting "but you can't do that!!!"
Had the phone for several weeks now. Took a LONG time to set it up and get it running EXACTLY the way I wanted it to. As part of that process, I installed Nova launcher, and an app called "DTSO". Anyway, when it was all set up.... I could double-tap the home screen to lock, and the display would go black. Then, *without using the proximity sensor*, I could double-tap the middle of the BLACK screen, which would cause the display to wake up and display the lock screen. I didn't set a lock on this screen, so I could just swipe up to clear it. Note I could double-tap the BLACK screen to wake it up.
So I was happy with the way everything was set up. Only problem was, it was not stable. Most of the time, if you tried to take a picture, the phone would freeze. (forever). Or sometimes a reboot would take HOURS (starting after the animated vkworld logo displayed) I tried several suggestions. It was not a bad memory card, and it was not corrupted files on a memory card. I tried clearing various caches, etc. Nothing worked. Finally, in desperation...I went to the factory boot menu (chinese, but I found a guide for it) and cleared hardware cache / emmc / whatever. That left me with *** CHINESE LOLLIPOP ***, and all my apps/settings/data were GONE...
So I had to start from figuring out how to switch back to English. And then starting all over again. I wasn't back to "zero". I went back to "minus one". (!!!!)
After many hours setting up the phone again with dozens of applications, getting my account settings input, getting it all configured...
The only thing I can NOT do now is to double-tap the black screen to wake it up. The phone is rock-solid STABLE now, so that is an improvement. But I want it to wake the screen with a double-tap, like it did before!!!
I'm now using "Go" launcher. But I (temporarily) tried "Nova" launcher, like I had it before. DTSO does not work like it used to. It won't wake up the screen while black. Again, this USED TO WORK, so it's not a hardware issue. What did I do wrong? What did I miss in setting this thing up again?
