I regret twice after getting Poco F1 (I bought two units. One in October, 2018 and one 1n May, 2019). LCD panel was of poor quality, touch sensitivity was a complete mess, thermal throttling was crazily aggressive, animation was crappy. I suffered to such an extend that I am scared to buy a Xiaomi device again. Currently using Realme X and apart from Color OS, I don't have any other issue.
