Tested with PinePhonePro.
I have used it for a few hours and it is generally good.
WiFi
Mobile-Setting now supports WPA-EPA.
Japanese input
IME
I can input japanese with fcitx5 and fcitx5-mozc. KDE’s systemsetting must be installed separately and configured from there.
I have added followings In /etc/environment.
XMODIFIERS=@im=fcitx
QT_IM_MODULE=fcitx5
External display
FHD with touch srcreen works fine.
[Problems]
When switching applications with the □ button, the screen goes dark and cannot be operated.
SIM is not recognized (Mobian recognizes it, so it is not a hardware problem).
Although it is an upstream problem, Japanese input on maliit keyboard has been unusable for a long time (downward flick overlaps with the action of hiding the keyboard and cannot be used for input).
I created a new user but cannot log in (I can su from konsole).
