a32 5g battery died and samshit wont repair it because of magisk, so i made this meme

Maybe so, but under the Act, the burden is on the company to prove that the modification directly caused the failure in question.

They can't just deny deny for no reason. But that's the tactic as consumers are largely unaware of their rights under the law, and they typically get away with it until the FTC sends a bunch of nasty letters telling them that they're breaking the law. See "warranty void if removed" stickers.

There's some good discussion of this very issue in this article from a few years back. They touch on the sort of "overclocking" situation that you're talking about.

In my personal opinion, even a modification that can be used to push the hardware to operate beyond it's design limits doesn't inherently void any part of a warranty if it's not used for that purpose. Let's think through a few examples.

Does obtaining root on a Windows PC void the hardware warranty since it's now possible for you to install a kernel driver that lets you overclock?

Does the presence of MSI Afterburner installed on a machine void hardware warranties? Regardless of whether you use it for overclocking or just for graphing and monitoring?

Does installing Linux on a PC that you own void the hardware warranty?

In my mind, the car example is a bit different. I don't quite know what you mean by "tune", but I'm going to assume it's something like ECU remapping. To me, remapping an ECU seems similar to the act of overclocking, since you're modifying the physical inputs to the engine itself. And I can see how out-of-spec physical inputs could cause irreversible damage to an engine. But that doesn't mean that every conceivable ECU modification would be grounds to deny a claim for engine failure.

(Disclaimer: I have no experience with ECU remapping so I'm making some assumptions)

As another example, let's say your car comes with an ECU that has some security mechanisms to prevent reflashing. Could the manufacturer deny a warranty claim on engine failure just because you circumvented the security mechanism? Even if you never remapped the ECU parameters?

What if your ECU fails, and you decide to install a 3rd party ECU. The new ECU has no security mechanism preventing you from reflashing, but the map that it comes with, while provided by the 3rd party, is functionally equivalent to that in the stock ECU. Can the manufacturer deny a warranty claim on an engine failure, just because without the security mechanism you could have reflashed a new map designed for more performance than stock? Even if you didn't? Could they deny the warranty due to the 3rd party map? Even if physical inputs to the engine stay within safe parameters?

I think you do raise a good point about the logical connection that Samsung could make between the modification (root) and the failure (battery). But the point I'm making is: the legal burden is on them to make that connection, and show how one caused the other.

On the other hand, some of the questions and examples that I raised are admittedly messy, and might not have a clear answer unless tested by a court.

I guess what I'm saying though is: if the cost to seek legal relief here is relatively low (e.g., arbitration or small claims), then if I were OP I would probably go down that route, personally, and make arguments based on Magnuson Moss.

IANAL

Edit: just saw elsewhere that OP lives in Greece. Looks like the legal principles are pretty similar when it comes to warranties in the EU. The burden is still on the manufacturer to show that the modification caused the failure in question.

But under the Act, they have to show that what you did caused the malfunction. The burden of proof is on them.

It's why "warranty void if removed" stickers on products are unenforceable in court.

Not exactly.

It's when there's a third-party arbiter. In the case of customers seeking damages against these companies, the arbitration agencies are paid for by the company, but often there's a list of arbiters the complainant can choose between.

My personal strategy has always been to pick the most expensive one so that whether I win or lose, the company stags to lose more money on the process than by simply making me whole.

The real reason for forced arbitration is because it makes DIY class action suits impossible.

Otherwise, a company with a class action waiver would find themselves facing 10,000 cases from the same law firm instead of 1 case with 10,000 plaintiffs.

With forced arbitration they can skip out on the cost process entirely and make the defendant do more leg work.

And, importantly, there's no precedent with arbitration. Losing the first case doesn't necessarily snowball into you losing the next 9,999 cases with identical facts.

battery replacements usually run around 60-90 at my shop depending on the device, if I ever walked in to a shop and heard 200$ I'd walk tf out that's insane pricing.

So someone got payed to wait for the phone to be shipped to them, took the effort to carefully and meticulously disassemble the phone, install the new battery by micro soldering the battery leads to the mainboard, then booted it to see it blew a shitty security fuse but can still boot fine, then took the time and effort to uninstall by removing the micro solder from the battery and mainboard without damaging the phone, just to tell them they can't do it?

Sadly I know very little there. I know I HATE my current Samsung (mostly due to the company practices like you mentioned), and I also felt incredibly betrayed by my OnePlus 7T before that (the device itself was amazing, until an update broke it and now it literally hurts my hand, like I wonder if it's giving me cancer by radiating something through the shielding that it burned through), and before that I absolutely adored my Nexus 5 (but Pixels are a whole other thing entirely - far too much camera and too little actual phone for my tastes). The entire smartphone world is incredibly predatory. I mostly figure that the next one I get will be a cheap phone, maybe even a dumb flip... but on the other hand I do live in an area where Google (or whatever) Maps could really help out so... I don't know what I'll do when my current one craps out:-(. Probably I will research a Fairphone, but if you live in an area where that would be difficult to repair, then yeah that may not be an option for you:-(. At least you live within the EU though where such is being forced to change, so you have that going for you.:-)

Can you not buy one online?

γερμανος κ ξερο ψωμι!

BTW: please don't root/install magisk on a phone you use <3

Looking though that it looks like Samsung made a comment

Samsung’s representative stated:

“I’m unfamiliar with the specific variables that could have come into play with this repair or the unsubstantiated comments from Mr. Jeffrey. What I can tell you is that there is no requirement to pair parts on our smartphones. If a repair were conducted correctly, a device would not lose functionality.”

I was checking to see if anyone made any additional comments on the Hugh Jeffreys video and someone said they replaced the screen but kept the fingerprint sensor and it still worked fine. I believe replacing the battery with a 3rd party option should still have the device working fine.

Hugh left a comment on the video as well:
