An update shouldn't make device slower. Why developers give updates..huh?
An update should always give performance improvement and better battery backup
As we are talking about updates here. Yes, I agreed Samsung should have delayed the launch of A series of devices. Because to compete with mid-range companies competitions Samsung in hurry launched their A series with their New but still unfurnished OneUI.
But at the same time, Samsung does listen to our complaints since we can see, after the launch of A50 they have provided a couple of updates shortly. Besides software development and improvement is something takes time. It will not work like over the night everything gets fixed.
Keep calm all our issues will get fix for sure. Samsung has a good track of customer satisfaction for years now. somethings do need time to get fixed.
