JJE,
I perfectly know Samsung's warranty policies. And i knew them before rooting.
I don't know in which country you are, but here in France (and more generaly in EU), producers (not only vendors) must warranty their product for hardware failure for 2 years, undependantly of software matters. It is their minimum legal obligation. That's the law. End of story.
The limited warranty (!= legal warranty EVERY SINGLE producer must give) that Samsung "adds" to it's legal obligations can only widen the minimum legal warranty (e.g the 2 years against hardware failure) and it can NOT narrow it down with limitations of their choice.
The point is, when you say "Samsung offer an extra limited warranty on top of your vendors warranty", it is simply not true.
Samsung does not offer an extra warranty compared to what the law forces them to offer. On the contrary, their limited warranty narrows the law down.
Now, in my case, yes my phone was rooted and i didn't even try to deny it. I had never flashed any custom rom nor did i overclock it nor did anything that may have overloaded/overheated it. Just removed the simlock, that's all.
So, when 2 different pieces of hardware in the phone fall apart, one of those going down less than 10 days AFTER they took it in tech service once
+ considering the fact that it is a problem that several customers have had (sudden death + others) :
Can I, honestly, be expected to be nice, shut up and accept being extorted 99€ for a lousy hardware (at least in the case of the copy i got from stock) ?
Anyway, i could whine for hours like this
I contacted Samsung (and legal services who deal with such cases) in France. I'll keep the readers posted about what comes next.
