[G3 Themes and Apps] topet2k12001:
Hi @LastStandingDroid,

Ah, yes, I think that was @galaxyhero's flashable zip. :)

Do you want me to test your G-Force ROM? Although I think you made it for the D855, so I guess I'll just extract the corresponding apps and copy-paste them to my D858HK, correct?

By the way, I got LG G4 version Messaging to work on the D858HK (dual-SIM variant). :) Here are the steps I took:

While booted to Android OS, replace LG G3 Messaging with LG G4 Messaging. DO NOT OPEN MESSAGING APP AFTER COPY-PASTE OR YOU WILL JUST GET A FORCE CLOSE NOTIFICATION!

Make sure that you disable any "Security" features in "Settings" like "SIM Lock" and "Screen Lock" (should be "None"). Otherwise, when you reboot your device after following the procedure below, your screen will always turn off (blank) and you can't enter the Home Screen upon reboot!

Should have modified lge-res.apk (please request from @LastStandingDroid) already saved to your device. You need to provide him with your stock lge-res.apk and framework.apk so that he can create a modified version of lge-res.apk for you

Reboot to TWRP custom recovery

Use TWRP's built-in File Manager (you should mount "system" partition first before going to File Manager so that you can see its contents when using TWRP built-in File Explorer) to copy-paste the modified lge-res.apk over to the old one. You can also consider backing up the old/original one (example, rename it to lge-res.apk.old)

Make sure to change permissions of the newly-copied modified lge-res.apk (select "Chmod" and type 0644)

Reboot to normal Android OS

Simpler but more advanced method:

Users can try downloading the D855 flashable zip (see First Page of this thread, look for "Messaging Fix for D855" and download it)

Open the zip file with 7-Zip.

Drag your modified lge-res.apk into the 7-Zip window to replace the D855 version of the lge-res.apk

Copy your modified "Messaging Fix" flashable zip to your device

Flash it with TWRP

I just happen to prefer the manual step-by-step that's why I listed the manual steps here. :)

Here's a report of the LG G4 version of the Messaging app:

Sending and receiving of SMS works without problems.

(Dual-SIM LG G3 users, e.g. D858HK): I think that the LG G4 Messaging app in this thread is intended for the single-SIM variants. The dual-SIM Messaging app has two (2) "Send" buttons, one for each SIM card. In this version of the Messaging app, there is only one (1) "Send" button. As a workaround, users can switch the SIM to be used in the "Quick Settings" pull-down. The same issue (and workaround) is observed for the "Dialer" app. Other than that, full functionality is still present. Users can still use either SIM card; they just lose the convenience of the two buttons within the app itself.

I lost the "double-tap-to-wake" feature, although the "double-tap-to-sleep" is still functional. This means users will have to manually press the "Power" button to turn on the screen. I am not sure if this is due to the modified lge-res.apk, or if this is because of disabling "Screen Lock" features, or simply because I have a dual-SIM LG G3 variant. I'm not sure if disabling "Screen Lock" (as a result of modified lge-res.apk) is the only way to get LG G4 Messaging to work; this needs confirmation by @LastStandingDroid
