I realize my title is confusing, when I say degoogle I really meant completely Open Source and private.
ipad with network disabled?
not feasible in my use case
apple backdoor is highly likely in my opnion
Of course I don't have any proof, but I would assume it runs camera and microphone without us knowing even when the network is disabled. The data is collected and processed locally and send to apple server when network is enabled
speech recognition is integrated in many app and sold to advertiser
I doubt apple could resist the temptation of money and the threat from government not to activate microphone and camera without us knowing
hmm.. the only other choice i can think of is a surface pro with linux installed. I have a Surface Pro 4 and its stylus works pretty well with the surface-linux kernel, but it isn't as smooth as an iPad.
If all you need is something to draw on, get a wacom tablet and hook it up to a laptop. Wacom drivers are in the linux kernel.
In college I've been taking notes on a screenless drawing tablet, its not too bad taking out a laptop and plugging it in. It doesn't take up much space on my desk if I put the tablet on my keyboard.
Alternatively, you may also be able to get a microsoft surface laptop working on linux
XP-pen has much more cost-effective options that are just as good nowadays since wacom hasn't innovated in like 15 years lol.
They also work out of the box in Linux, but for all of the shortcuts, they also have driver packages for every distribution and if it isn't available, support will package the newest version for you (in my experience) in your chosen format and then send it to you and update the driver downloads.
The XP Pen Deco Pro Gen2 is an absolute beast for a drawing tablet.
XPPen also has a android drawing pad but that is normal android I think.
If OP wants the drawing tablet experience with a screen, they can also get XPPen Artist Pro display tablet series which of the few artists I know in real life, are what most of them use.
An actual drawing pad is much better than even an IPad for drawing, and you can also use whatever program you want (like Krita), not just the neutered programs that come on iOS or android.
Anything more than general stylus use on a Pixel tablet with GrapheneOS has been very hit or miss with me... aggravating. I fall back to my 6 year old iPad even when I just need to annotate notes. l firmly believe it's the fault of the hardware.
iodéOS has official support for the Galaxy Tab S5e, which is on the list you linked. I own one but I don't use it for art so I can't comment any further.
The support is fine. It doesn't have 5G because it is not a 5G device (and one model, the WiFi one which I have, does not have any cellular capability). It doesn't support VoLTE or bootloader locking because it is a Samsung device (you always lose these features with Samsung devices unless the ROM is based on OneUI). It doesn't support the automatic iodéOS installer because, again, it is a Samsung device - you have to use Heimdall. I'm not 100% sure about the firmware bit. I believe that is referencing whether the ROM includes the latest manufacturer firmware update as well, but I can't say for sure.
