Thank you for this information BionicGecko

I am very interested in this.
I already did the JB on my KPW5 and yesterday successfully also on the Oasis 3. The only thing I missed is adjusting warm light possibility with one finger gesture on the right side at the Oasis 3.
On the KPW5 this still works fine

I know how to get a nightly on a Kobo, PB and Android device, but not on a JB Kindle. That’s a new thing for me.
Maybe someone would be so kind to explain it what to do, that would be great!
Thanks in advance
