No need to flash incall fix on our device

Can we disable the navbar?

 

[newbie_or_not_newbie]

Hi

Can we imagine some "P" custom roms we could flash directly, like other oreo/nougat roms ?

 

[stevenlopes92]

Flashing these system.img and other post gsi zips wont work on any other treble enabled rom ?

 

[yogasetyaadi]

Can we disable the navbar?

Yes, by adding line in buildprop

qemu.hw.mainkeys=1

Maybe u have to wait longer. Are you not familiat with treble?

 

[sashgmore]

its quite good rom for daily use if you will manage without VOLTE. Battery backup is decent and rom works as sooth as butter.

Not so much... I see what it is, but can't realize what consequences for santoni, for custom roms.

If im correct, it means our devs have just to work on /vendor so we can flash gsi of ROMs that aren't built specific for santoni. Also updating hardware related things are completely independent of Rom Updates.

 

[newbie_or_not_newbie]

I understand more now, how difficult it is for devs.
Thanks for explanations.

Hey all i was saying is that now i am using treble enabled lineage os 15.1
Can i flash the system.img and other post gsi-zips above my base of lineage os , or is it mandatory to flash RR luis rom ?

i got bootloops on my phone with lineage os15.1 vendor.
luis rom vendor works well with p gsi img.

i am using Los treble by swapnil bro, as base rom..

its working fine.. no issues at all..

dont neglect to keep Playstore apk ready after you boot, else it would be nuisance

Yup stable enough, some small bugs are there like cannot turn Bluetooth and WiFi on at the same time and YouTube seems to stutter.
Other than that everything works fine. Does heat up a little bit though.

I'm just trying DP4 and flashed all 3 zips after the GSI but the device doesn't sleep. Anyone else?
BT and WiFi at the same time isn't.possible, it seems.
