SmartphoneUMIDIGI A7 Pro lags / jerks when watching videos on Youtube and Twitch streams at 1080p60fps?

My problem is that I can't watch videos or streams at 1080p60fps because it is very jerky. I have already tried to activate "Deactivate hardware overlay", unfortunately it does not work either. I'm relatively happy with the phone and would not like to switch since it was quite cheap. That would be the only flaw in that part in my opinion. Would be very grateful for helpful feedback!

"because it was pretty cheap"

There you have the reason for the stuttering, the processor is one of the lower quality class.

A shame, thought I'd finally found something good…

The service that UMIDIGI delivers is ok for the price. The heart of the cell phone is the Helio P23 from Mediatek. It dates from 2017 and was used as a mid-range chip at that time. However, that was years ago and a lot has happened on the market since then. Nevertheless, the chip is a popular choice for entry-level cell phones because the performance is easily sufficient for simple tasks.
