I am looking for the fix of audio balance in Pixel Experience (Android Pie). The left channel is much louder than the right when using headphones. Will this kernel fix it? Thanks

Nope, its config issue, and this kernel won't solve the problem.

 

[elliwigy]

Thread was cleaned. Let's remain on topic.

Disagreements should be handled via PM and/or through the reporting system.

Thanks!

 

[LinuxPanda]

A small config change, so please update. Thanks.

Does it have USB fast charge?

I don't have fast charger to test, so I don't know.

I have a 5v/2a charger and it charges around 4.1v/1.8a when I tested before few mins. In previous releases, it never crossed 1.5a.

Forgot to add wlan drivers in the previous release, so took it down & another release, 20190109_1.

If you guys are talking about "Energy Aware Scheduling" then I should let you know that I tried some configs with WALT but it caused random shutdowns, so I dropped it.
