Samsung Blocking Third Party Repairs?

why not disallow it for "nonportalable" devices also if its such a security advantage. i guess they are going to advertise removing the lightning port as improving security also

Just because something isn't portable doesn't mean it can't be exploited to gather data from. It's just that portable ones are more susceptible since they can be stolen or forgotten somewhere easier. Same principle still applies. And ports can be an issue as it was evident from Thunderbolt just bolting straight into memory access. I'd say that's pretty problematic...

Man, all Samsung's ads criticizing Apple for their anti-consumer moves are looking REAL ironic about now...

Samsung has a track record for making fun of apple and then doing the EXACT thing they made fun of...
They made fun of apple for removing the headphone jack, now they removed it

They made fun of apple for not including a charger in the box, now they don't

Yea, EXACTLY; like what's next, a bootloader which voids your warranty if you unlock it?

Wait...

There is absolutely no reason why genuine parts pulled from a phone shouldn't work in a different phone of the same model. Especially something like a display which is probably one of the most common parts to break on a smartphone.

I do completely understand that they can require a calibration step for displays, since that is something that happens at the factory not every display panel is the same (even if they are form the same batch small defects have impacts) so part of the calibration is to detect these differences (in brightness, cooler reproduction etc) and store these somewhere so that the OS can read the info and adjust the signal it sends to the display. Some displays units include this on a small bit of memory that is part of the display unit, but that does increase the cost of the display unit and means you can't just replace the panel you are forced to buy the full display unit for replacement. It would be nice if they let users replace the screen and just put a warning up saying `your screen is un-calibrated ...` 

With respect to blocking the fingerprint sensor this makes lots of sense, since Samsung have digital wallet support with some banks (your phone can act as a contactless bank card) they have some strict requirements that need to meet. Just like a card terminal in a shop has all the internal parts paid with each other the banks require the same of auth system used on the phone. Again would be nice if they let you continue to use it but  disabled these features that they legally can't support without calibration and provided a warning to users that the fingerprint sensor `can't be fully trusted`...

That would be Samsung doing something of their own, apple do not have such a boot-loader, if you jailbreak your device  you can always flash back a non JailBreak os (using DFU mode from iTunes and there is not trace a JailBreak was installed).  Apple or Samsung could put something in firmware that made this detectable some games consoles in the past have used eFUSE https://en.wikipedia.org/wiki/IBM_eFUSE to stop you being able to install OS downgrades after installing an update.

People who tried to jailbreak their iPhone or upgrade their iPhone face this problem quite commonly. When iPhone is stuck in Apple logo, it equates to a toy without batteries, you can do nothing with it, you can't call anybody, you can't text, and can't take pictures with it. It becomes  totally useless.

So you can reset from this using the DFU reset that fully re-flashes the firmware. (warning you do loss all data on the device). You need a mac or a pc with iTurns installed.

So you're telling me that Samsung is even worse than Apple when it comes to tolerance in practice of "non-EULA/warranty-abiding" user mods? Bruh...

My thoughts

I think this is ridiculous and really hope this is just a bug and not an intended thing. Samsung has been slowly copying Apple's bad decisions and if this is another one they decided to copy it should be met with backlash.

You mean Apple's good decisions. You after all don't want someone who steals your phone able to unlock it by swapping the secure enclave with another.

 

The thing that Samsung likely botched here is having a process to backup the secure enclave, disable the driver to it, replace it, re-enable the driver to it, and then restore the enclave.

 

This is the same thing that happens on Windows laptops if you don't turn bitlocker off before doing various maintenance items. 

 

I'm sure Samsung was tired of losing to Apple in the government/business contracts.
