Not exactly a budget tab, but I've found the S8 Ultra (and the S7 FE before that) to be pretty great. The S8U managing to make having a laptop entirely unnecessary (since I'd only need a laptop away from home and I mainly WFH).

> only Samsung doing custom stuff like DeX, Motorola has phones that do the same and without a proprietary dock.

No dock required. With Samsung DeX you just need a cheap USB-C to HDMI cable. Plug the phone into the monitor and you can switch to desktop mode.

It only works on Samsung models that have USB-C video though. My mid-range Samsung phone doesn't have either feature.

If you make Apple devices totally worthless to thieves, you discourage theft. Make them bricks which can't even be harvested for parts. That's the goal apparently, and it makes sense.

This. As a user I'm okay with using only authorized components if it makes theft virtually impractical as there wouldn't be much to use even if the device is stolen. It will give me more peace of mind as no one will have the incentive to steal an iPad anymore.

Does anybody really think that one company removing users freedom at the software level, will make thieves not steal hardware worth $1000+?

This is some silicon valley tech bubble mentality.

Not all replaced iPad screens. Only non-OEM (third party) replacements.

Wrong.

A genuine screen from another iPad will cause this issue until you swap the chip from the old screen to the new screen.

Tangential rant. Has tablet computer really improved since the last Google Nexus 7 tablet, which was released in 2013? Seriously, I was in the market for an affordable tablet, and quite bizarrely the tablet computers today have significantly underwhelming spec compared to a phone of the same price point. There is no budget tab from known manufacturers. Even at IPad level prices, the android counterpart is quite under…

I have a Samsung an android tablet with their pencil. Using Krita for drawing I think it’s pretty amazing. The UI is kinda desktop but the brushes are amazing.

For displays I imagine the reason is more reputation and experience - normally just about every apple product has a factory calibrated display, but that promise can be broken (intentionally or not) on the used market. It’s nice to have a means of checking whether a display is legit other than eyeballing it That being said, I can’t think of a reason for blocking correct pencil functionality. It doesn’t seem like somet…

It might actually need calibration. And if it does it would damage the reputation of Apple's products (iPad and Pencil) as they won't work accurately and will glitch, creating a subpar experience which Apple would obviously not want to be associated with their products.

Calibration is like wheel alignment. What is happening here is :

Changing tires for same brand and model car came from the dealer. Car no longer drives in a straight line, steering wheel feels wobbly at certain steering angles.

You saying its a wheel alignment issue.

Replacing TPMS sensors with ones from the old wheel set. Car magically starts driving straight and no more weird wobbles.

Apparently it is not. The reddit thread has an ex Apple employee who runs repair shops in Germany. He says if you just change the serial number of a iPad screen(using specialised hardware) in existing iPad this issue will appear. This seems to indicate that it’s intentionally done by Apple. Other option is that Apple bakes in calibration details of all possible serial numbers in every iPad sold which doesn’t sound li…

Why would the calibration details need to account for all iPads sold? Just bake the one that the device is bonded with, using the display serial number as a lookup key. Then, if you change the serial number of the display, the lookup would fail, and fall back to whatever "default" values are.

and just be shear coincident two screens, the broken one and replacement, match calibration data completely?

Could be calibration is looked up via serial number by the iPad and the third party ones don’t have any cal on file.

There was no third party display, replacement one came off another working ipad.

Are ipad thieving gangs really breaking down and on selling stolen components?

Yes. I have a friend who works at Geek Squad and had to service someone who got their iPhone chop-shopped. Someone had stolen the phone, swapped out everything with knock-off parts, and then left the phone behind. The victim flagged the phone as lost on Find My so they at least got a free warranty replacement. The fact that chop-shopping is a thing with phones now does not excuse Apple's parts serialization shenaniga…

I am not doubting you, it just is really weird that they would bother to replace the parts at all. my guess would be to try and sell the chopped unit as a real iphone? but why leave it behind?

This is my assessment as well. iPad with Apple Pencil, mirrored screen for photoshop, and you have a seriously good and portable wacom centiq. Just, smaller, and can play games.

How is the pressure sensitivity compared with a "real" drawing tablet?

It's as good in an app that lets you adjust the curve to fit your hand (like Procreate, which is an industry standard at this point.) A Cintiq's curve is a little better out of the box, in my opinion.

It's pretty great but it also costs a lot more than than a basic laptop :)

Oh yeah, for sure. I got the S7FE for the S pen and battery life and upgraded to the S8U when it launched a few months later due to a pretty good trade-in deal. So it cost me a lot less than retail.

I hadn't intended for it to be much more than a portable drawing, reading and note taking device when I bought it, it just sort of fell into the laptop replacement role.
