Hello people.
The D855 I sent to a shop for fixing returned back with root access open. Asking them about it and why was it done, they simply told me that in D855 after a motherboard replacement (which is the case with my phone) they need to open root access in order to calibrate the 3G/4G connection that can only be done with root access and if it is not done that phone might experience connectivity issues and/or non accurate GPS (which are both present). They also said after making the calibrations they update a higher level version of Android and therefore have the root access removed. They said something must've gone wrong in my case that they haven't cleared root access and they apologized.
My question is, are they saying the truth about calibration part? I have never heard of such a thing. Does anybody know something about this case?
