Changing visible/used area in display, Enable SoftKeys

[8poke2]

Changing visible area in display (soleved)
On some webpages words are too left and for better reading I changed the indent for my Poke 2 from left and right 6 pixels.

adb shell wm overscan 6,0,6,0

Enable SoftKeys (not solved)
I like to have software keys on the bottom. Movable ball can do things on 2 presses. What is easier? Root device* and use old way with file “build.prop” and add there line

qemu.hw.mainkeys=0

. But without root i see

dd: /system/build.prop: Permission denied

I tried

adb shell settings put global qemu.hw.mainkeys 1

and after reboot nothing new. 0 also nothing.

Or any app like: https://play.google.com/store/apps/d...irtualsoftkeys (not working for me)
https://play.google.com/store/apps/d...usumit.ortatus (not working for me, problem with permissions)
https://play.google.com/store/apps/d...?id=nu.nav.bar (not tested after two fails)

Trying with adb something from:

adb shell settings put global policy_control immersive.full=apps
adb shell settings put global policy_control immersive.full=*
adb shell settings put global policy_control immersive.full=
adb shell settings put global policy_control immersive.navigation=apps
adb shell settings put global policy_control immersive.navigation=*
adb shell settings put global policy_control immersive.navigation=

was not the sollution. Only status bar was affected after commands. After change and reboot nothing was changed.
Info: https://forum.xda-developers.com/t/h...ndows.3554299/

I found in device settings nothing about immersive.navigation. There is only immersive_mode_confirmations= in secure area:

>adb shell settings list secure
...
enabled_accessibility_services=com.onyx.floatingbutton/com.onyx.floatingbutton.service.FloatButtonAccessibilityService
immersive_mode_confirmations=

Nothing relevant in system, global area.


This is probably also for rooted devices or old way. I cant run it with adb.

root@:/ # setprop qemu.hw.mainkeys 0 //to turn ON soft keys
root@:/ # setprop qemu.hw.mainkeys 1 //to turn OFF soft keys

Root device*

The Poke3 loses a couple of pixels on the edges.
You can see them if you look at an angle, but not straight on.

You need root for most of what you're doing.
You're also mixing up a bunch of stuff.
dd is for copying disk partitions (among other things)
properties are set using "setprop" (like qemu.hw.mainkeys)
settings are set using "settings"

Changing parts of /system might make updates in the future not work correctly.
Right now (I think) the Onyx updates are not really incremental.
But they could be later.

Does your browser have a default style sheet? That's where I'd start.
