I was interested seeing, what Samsung says about rooting before I bought my phone.
Samsung is still saying, that rooting voids any type of warranty. Even after linking them to old story how one of EU Regul tehnicly allows you to root and you would probably void only software warranty (its **** anyway, as reinstall is first thing they do in service center).
After they told me it still voids warranty, I e-mailed goverment organization, which is resposible about customer rights etc. I linked them to this regula and another topic from guys who "digged it deep". Answer was still the same - Samsung is allowed to void warranty in this case, just because they have stated it in their warranty paper.
So only way I can get it fixed in Latvia is by Court... Or lucky service center specialist.
