Post your KCAL values here

Ice Bear · Nov 27, 2018

Ice Bear wasn't sure where to post this thread. Recommend some good KCAL values for the V20, preferably one with little to no screen retention. Perhaps some might want deep blacks and vivid colors while others might want more natural colors. Edit: It might be a good idea to mention whether one is using a stock ROM or a custom ROM. Ice Bear isn't sure if KCAL values have a different effect on stock ROMS vs custom ROMS. Edit: KCAL profiles have been rearranged in alphabetical order and now fall under 2 categories: User KCAL profiles and Kernel Adiutor Mod KCAL profiles.
Thanks to @SupaKid for posting a link to a similar thread.

Ice Bear went ahead and gathered KCAL values from it. Credits go to the users of said KCAL values.

I used to be on R:245 G:245 B:245 and it worked just fine but since summer came, retention got worse and I had to drop to R:235 G:235 B:235 instead.
If your panel has kind of a blue tint (mine doesn't) you just lowed the Blue value by 10 compared to the others.

The best way to calibrate your KCAL values is to put your phone right next to another phone that is well calibrated (an iPhone for example) and try to match the colors.

Wonderful tip for those trying to calibrate their V20 screen like the iPhone's screen.

Wow, Ice Bear saw a few different KCAL values posted on the thread you shared. Thanks for sharing! Perhaps Ice Bear shall edit the first post and include those people's settings as well as crediting them.

Can I use live display to bring rid of ghosting without kernel auditor under "kcal" call is off?

Ice Bear says yes. It does have color adjustment and picture adjustment after all, which is practically KCAL.

I use banged up profile on kernel adiutor mod, no retention or ghosting, looks wonderful feels like I have an amoled display.

I was wondering where this thread went. Thanks. I used the first one as it was the closest colors to an iphone screen. I just need to reduce the RGB 10 points lower because I still had ghosting.

More To stock color without screen ghosting?

nkirk · Nov 17, 2018 at 7:56 AM

I'm experimenting with the below setup in Oreo, thought of sharing for others to try out. This time colour temperature corrected with the use of the adjustable comfort view option.

What I tried doing was to match primary colours with a Samsung J series amoled device with AMOLED Photo profile enabled.

It came out close enough I thought, nowhere perfect. Wish kcal offered individual hue control per color channel.

If you are used to the super blue tint this setting will take some time getting used to. Also note each panel will have some variance in color response as well.

Ps- no screen ? ing

No problem! Ice Bear got the idea to post this thread after searching for a KCAL thread for the V20, but Ice Bear failed to find such a thread. Ice Bear was interested in the idea of other users sharing their KCAL values. There's quite a variety here.

C D · Nov 21, 2018 at 2:57 AM

I use maxi65's values as listed in the OP and this thread from a while ago and never had a problem with screen retention on my LS997 ZV7 (old stock-based custom ROM, Android 7.0) and US996 USA (old LineageOS-based custom ROM, Android 7.1). I'm not too picky about colors, so I've never bothered to change the values. The Kernel Adiutor Mod app that I use does have quite a number of preset values that could be interesting (see attached images). Some of them have been mentioned in here and in SupaKid's linked thread. If anyone is interested in seeing the numbers for some or all of the profiles, I'll be happy to post them.
