I think something is just wrong with the haptic motor Samsung puts in their devices. I have an S24 and I thought there was something wrong with mine also. I don't use haptic feedback on touch but have some things such as messages set with vibration. The first time off it set at about 50% and I could barely tell it was even vibrating. I turned it up all the way and I can't believe how week it is. I come from a budget Motorola phone and when that went off you knew it. Unless we both got dud haptic motors I just think Samsung went the cheapest route on them and this is what we ended up with.
