When we had MM, I created the 60fps mod here:
On Android N LG provided 60fps built in so this mod is just for higher image quality and (if you wish) high bitrate video.
I did just basic testing so, as always:
As always, backup your device before. Just in case.
I am not responsible for any damage to your phone from using this mod.
There are 4 packages:
1. Back to original stock (N) configuration:
2. Higher image quality. No change to video bitrate:
3. Higher image quality. 1080p bitrate 30Mbps (default is 17Mbps), 4K UHD bitrate 64Mbps (default is 48Mbps):
Warning: 100Mbps 4K will create heat and drain battery. I tested it for few minutes, I can't tell you how it will behave it longer use.
4. Higher image quality. 1080p bitrate 30Mbps (default is 17Mbps), 4K UHD bitrate 100Mbps (default is 48Mbps):
I did not create 200Mbps 4K video because the maximum allowed by LG was 100Mbps. It is easy to set it to 200 but I am not sure how safe it is. If you really want I'll add a 200Mbps as well.
Just flash it from TWRP. No need to delete cache\dalvik etc..
Flash the original file (#1) to go back to how it was before.
I only tested it on my H850 model.
