> There are currently no instances of litigated cases about warranty issues when rooting, flashing, or jailbreaking smartphones in Europe, nor has there been a rule or provision on this issue. This makes the legality of such acts unclear. So, you can root your phone, but if you wish to keep the warranty intact without any problems, then reverse the root to the stock operating system and check if everything was undone. If the stock OS functions as it should, then you do not have an issue.
