Just got a brand new Nokia 7 Plus and the performance is awful. Way worse than what's supposed to on a Snapdragon 660. There are frame drops everywhere, specially when switching between apps. Is this a problem Nokia is aware of? There are hundreds of testimonials all over this forum, Reddit, XDA and Youtube on the issue. I'm returning this phone today and will only consider buying it again if these issues are solved.
Can relate. My old Samsung Galaxy J7 2017, which is a lot weaker device, does not stutter.
