Indeed, and for more clarification, as Arm's naming scheme easily causes confusion :
ARMv7 and ARMv4, used by the ARM7TDMI processor core in the GBA, NDS and 3DS, are not the same instruction sets. You can indeed find processor cores in recent microcontrollers/SoCs implementing Armv7 or Armv7-M.
The SAM9x60 has an ARM926 core, which implements the Armv5TEJ instruction set, similar to the DS' ARMv5TE instruction set implemented by its ARM946 core. The former has Jazelle while the latter doesn't.
I have been using a Pi 4 as a desktop computer for a few years (didn't have anything else) with an microSD card and without any fan, heatsink or case. Haven't had anything problems. Obviously, this depends on your environment, but it worked fine for me.
Same thing with KDE Plasma and its UIs being written in QML, which allows better separation of business logic (written in C++) and graphical interface (QML Javascript).
Yep, this was also the case with my old phone. Opening apps took a while but after that, everything was more fluid afterwards and clearly indicated that storage played a part in the device's slowness. Though, the 1.5 GB ram and the quad-core Cortex-A7 still made the device pretty slow.
This nicely did the trick! Adding the line at the top of /etc/pam.d/system-auth makes sudo authenticate use the fingerprint, which is nicer than always typing my password and gives a streamlined experience between SDDM and sudo.
