Installed twrp-3.6.2_9-0-herolte, lineage-20.0-20220919-UNOFFICIAL-herolte, NikGapps-core-arm64-13-20220908-signed, Magisk-v25.2 I installed everything that I usually use, everything works fine, smoothly, without errors, except for the backlight of the buttons, but this was mentioned. The only problem that does not allow you to use this firmware, when the interlocutor hears himself, he has an echo. This problem is probably on all custom firmware and it can not be solved in any way. It is extremely inconvenient to use because of it. If there is a way to fix this, please let me know.
