It’s on my todo list, coincidentally… (a 64-bit ARM Linux app) [so definitely agree] Actually I’ve already made a suitable app, I believe, and am planning to install it on my test project very soon, and if all goes well hopefully live fairly soon after that - so watch this space… J ____________

…though I suppose I ought to add: Thanks very much to the UserLAnd devs for re-enabling 32-bit mode loading, which has at least allowed me (and us) to use the 32-bit app on Android. In my early tests, the as-yet unreleased 64-bit app is almost exactly 4 times faster tho’ ____________

I can vouch that the new 64-bit Linux/ARM 1.16 app is twice as fast as the 32-bit 1.15 app was on a 64-bit platform, what do I need to do to test the 64-bit Android app? Is signing up for the project on my Android 9 running Odroid-N2+ enough? ____________

There is no specific Android app - the idea is to use UserLAnd :) ____________

Thanks for that benchmark Dirk. I’ve yet to try a 64-bit OS on (one of) my Pi, though I think it could run it - it’s a Pi3B iirc. These days (since about 2017 :) I tend to use Amazon Fire tablets - which I can broadly recommend… J ____________

….mind you, I’ve got a holiday to Cambridge planned, from which I hope to bring home a Pi400 as a trophy! Recently bought a Pi400 and installed the OS on SSD from the web, straight via the bootloader. Works like a dream, no more slow and/or corrupted SD-card problems. ____________

My idea is that the project will served by a 64-bit Linux/Aarch64 application in the view of Apple's move to ARM and the rise of 64-bit SBCs (e.g. Raspberry Pi 4, Odroid-N2)

Other missing platforms are Android/ARM, both 32-bit and 64-bit, and PPC (for old Macs, either OSX or Linux, both 32-bit and 64-bit).

I overclocked it to 2100 MHz via the following lines in the /boot/config.txt

force_turbo=1
over_voltage=8
cpu_freq=2100
gpu_freq=750

put it on kernel 6.1 via
sudo rpi-update next

After that I got no video. I had to uncomment the next lines in /boot/config.txt
hdmi_force_hotplug=1
config_hdmi_boost=4
and changing
dtoverlay=vc4-kms-v3d into dtoverlay=vc4-fkms-v3d -note the added 'f'

After that I got video, but no task panel. Changing the HDMI port cured that.
