For configuration of the touch keys, see Tm2-touchkey.
The brightness of the display can't be adjusted, this is not available yet.
rt5033-charger driver is not available, so the charging is not controlled and there is no charging status reporting.
There is also a forgotten patch, Jakko is looking into this.
rt5033-charger driver issue. It's currently unable to power up a usb device in mainline. Try a hub with external power supply.
Currently WIP. It can be controlled with SG Micro SGM3140 charge pump LED driver.
Suspend is not yet fully implemented. It's recommended to disable suspend. See Qualcomm_Snapdragon_410/412_(MSM8916)#Suspend.
Display sleep issue in X11
At some point a regression came up. In X11 user interfaces like Xfce4 and MATE, when the screen blacks out after a while of inactivity it can't be woken up anymore. As a workaround, set display sleeping time to "never" in the power managament settings. To solve this issue properly, work on the panel driver would be needed. See pmaport issue #1570.
Mirrored screen on Plasma Mobile and GNOME mobile
On samsung-serranove the display natively shows everything in flipped/mirrored way. To compensate this, the cmdline in /etc/deviceinfo contains
video=540x960,reflect_x. In Plasma Mobile the screen handling is done by KScreen. As KScreen doesn't support flipping/reflecting, everything is shown mirrored. There is currently no solution, work on the panel driver would be needed. See pmaports issue #1340.
As it turned out, also GNOME mobile is affected by this. While Phosh and GNOME use "mutter" as a Wayland compositor, GNOME mobile uses "mutter-mobile", which is in an experimental state and currently not capable to flip the screen.
