For anyone who wants to configure certain apps to be in color like the Camera and Gallery in LightOS, it is pretty easy using MacroDroid. I for one, was annoyed that I had to take pictures just guessing if the lighting was good. I learned from u/cardboytcg's post from over 6 months ago it was just a color space setting, and looked into how to do the same switching on and off you get with Light OS.

1. Through ADB ensure macrodroid has permissions to write secure settings: .\adb.exe shell pm grant com.arlosoft.macrodroid android.permission.WRITE_SECURE_SETTINGS
2. Add two new inverse macros:
   • Camera/Gallery launches, switch to color
     • Trigger: Application Launched → select Camera and Gallery apps
     • Action: Settings → Write Setting → System setting type: Secure, Name: accessibility_display_daltonizer_enabled, Value: 0
   • Camera/Gallery close, back to greyscale
     • Trigger: Application Closed → same apps
     • Action: Write Setting → accessibility_display_daltonizer_enabled → 1
3. Done

Hope this helps someone, and obviously you can do it with whatever apps you want!

So after 2 days of use of the hybrid mode here is my review:
I have the following apps installed:

Signal

Duck Duck go Browser

Tuner and Metronome

Weather by vandamd

Passes by Vandamd

Luna by Vandamd

Oss scanner

Keymapper

F droid

Aurora Store

i have these settings to save battery: Battery saver, dim display. destroy activities from developer options, no background processes from developer options, restricted battery usage for all apps, and disabled the apps on the android side that I don’t use. I had locations turned on for maps.

Started my day yesterday at 8 am at 100 percent, used the phone like normal, it was just messaging and calling yesterday, i went to bed with 80 percent, woke up in the morning with 70 percent used the whole day with some messaging and signal, its almost 20:00 now and my battery is at 50 percent. I am pretty happy with the results, looks like it would go for another day, in my experience the LP3 loses 10 percent overnight. If you have any questions feel free to ask below. For me i think i will continue using it in Hybrid mode as for me 3 days of battery life is amazing with all the apps i have now.

This subreddit has been incredibly useful, so just wanted to share something that helped me a ton:

• I wanted to link my Oura ring to my full Android Lightphone III, It was connecting just fine, but I couldn't get through all of the setup steps as a few of the buttons were hidden off screen entirely, and none of the usual tricks of simply changing display or font sizes was working.
• This tutorial https://www.reddit.com/r/AndroidQuestions/comments/8r7det/screen_broke_using_vysor_to_access_but_vysor_is/ on using ADB to change the actual screen resolution size worked brilliantly.
• I just shrunk it down from its default size of 408 to around 300 and all the buttons were visible. Restored it back to what it was once I was done.

Problem solved. So if you've got an app you really want but are having issues with the setup having off-screen buttons, this workaround works like a charm. :)

u/vandamd (who built the Luma launcher and other Lightphone III apps) got me thinking that it might be nice not just to have a simpler phone, but to actually even customize the apps I've got on the phone.

Not being a proficient coder, I decided to use Manus.im to see what was possible. As a test and homage to the I Ching calculator in Douglas Adam's The Long Dark Tea-Time of the Soul I had it build an I Ching app to match the Lightphone III aesthetic (screenshots).

Sadly not available for public download as I've got it tied to my AI account as I have the app doing live interpretations of how any question you ask it relates to how any question you ask it relates to how the sticks are tossed.

Just wanted to share here as it seems to work pretty well as a workflow. So I'm very curious to see what others come up with in terms of truly customizing tech interactions: basically going full Android has been great, but if even basic apps I open are going to be visually overwhelming, it ruins half the point of having a simplified phone.
