I already tried to install those, they’re too old to even install. Thanks for the reply anyway.

Try Evernote maybe?

Wow! This sounds really interesting. I am definitely intrigued by your idea. If this was an existing game today I would for sure give it a chance.

I would practice soldering at least a few times before trying it on the phone, but at this point you don’t really have a choice. Moving forward buy a phone like the Asus Zenphone10 which has the battery glued shut but the back is plastic which would make it far easier to remove than a glass back phone. And bonus this phone has a headphone jack as well.

Yes, but the idea is that because the code is open source anyone can look at it and determine on their own whether it is in fact safe or not. Generally speaking the open source community is very good at figuring this kind of stuff out but I would say your fear is not necessarily out of place since nothing is 100% guaranteed. That said though, the more popular FOSS apps are quite safe.

Oh! true, completely slipped my mind. Install it in another PC or use an M.2 enclosure with USB C to partition it and clone the original.

I don’t own a Steamdeck myself but since it’s Arch Linux based there should be a partitioning tool like GParted built in.

You may want to check if it is partitioned.
