Theoretically, they are not warranted.
Because root, to put it bluntly, is to illegally obtain the highest authority of the phone, which may cause the instability of the phone and even other problems.
If there is a problem after rooting, it is man-made damage, of course, the official does not allow it.
However, because there are many benefits of rooting, Android phones lose a lot of playability without rooting, so some domestic Android phones have lower restrictions on root in order to attract consumers.
That is to say, these brands of Android mobile phones will not approve but also do not impose restrictions, after-sales will turn a blind eye to it according to different situations, after all, problems after root are not necessarily big problems, some problems can be solved by flashing.
But big brands are certainly not allowed.
It's not necessary to worry about root affecting the warranty.
Because as long as it is an Android phone produced by a regular manufacturer, it will continue to launch official ROMs and bottom packages.
As long as your Android phone doesn't turn on at all or is completely bricked, just flash back to the official ROM and you're good to go.
It's no different from before root.
