My XZP phone's performance is very solid and smooth on heavy task like loading game and 4k videos, but it seems very strange to me that a simple task like scrolling through the call log make it stuttering, and this happens very often. Sometimes, it feels like slow motion when switching between call log and contact tabs. Probably this is just a minor bug, and also the two front speakers are not at their potential at all. Please fix these, Sony.
