It is a good thing to copy something if it is good. And that is what Samsung is doing, the only caveat is that it is good for their margins (less cost to manufacture the device in the case of the battery, microSD and headphone jack plus the revenue from upsellong higher memory cuts and wireless earbuds) but it is not good for consumers.
Regarding the titanium body marketing is king in companies… Apple needed it because stainless steel is to heavy and they needed something premium sounding and lighter to replace it. Samsung and the others who use alluminum did not need it as alluminum is lighter if titanium has the same dimensions but from a marketing pov they would be behind Apple hence why everyone is rushing to put it inside their phones.
At the end of the day is the costumer’s fault for buying artificially limited devices and for following marketing crap…
The original game launcher and game booster (I am speaking on the one which came out with Samsung Experience UI on the S6 and S7) was the best, it allowed even for texture scaling. The current One UI launcher has been going downhill year after year :(
