@Duper thanks for your answer, @itsclarence thanks for this work
That’s what I am looking for, but I don’t know what is involved by using an unofficial build. I don’t have too many technical skills, nor too much time to manage my phone. Will the official updates be possible afterwards ?
Why the work done by @itsclarence is not integrated by /e/ ?
Meanwhile I found this post: Release plan for /e/ R on new and supported devices
The build for Samsung Galaxy S5 - klte is scheduled for 2021W43, I hope it will be delivered this time - I also found this post: [Device Roadmap] Android 9 (Pie) & 10 (Q) : The plan whith Android 10 Q but the build was never delivered.
