Sending your device to service center for any warranty purpose? Make sure to unroot your device first as doing so will reinstate your warranty and you will have no problems at the center. Unrooting should also restore your device to stock firmware, so all the modifications you’ve done on your device will be lost and you will have a fully stock device.
