My side button (power button) iphone X cannot function anymore.. Even i had restart the iphone and it still cannot be use
This guide shows how to remove the power button at the end of the disassembly: Make sure to skip steps 4, 9 , 10 and 11 as it is unnecessary for your repair. Then just work backwards to re-assemble. You can also order a new power button and cable here. You may also want to order new adhesive for the battery as it will move around a little without it and feel weird when using the phone afterwards. Hope this helps. :)
