I have an iPhone and a Samsung Galaxy. I use both: the former for my personal life, the latter for work. The Samsung is more flexible (fewer constraints) and much more integrated with my PC. The Samsung has many small functions useful for work. It is more powerful but a little more complex. The iPhone for my personal life is good. It is simpler and I use fewer apps and less social. My opinion.

I had the same problem (I posted it some time ago). At the end, the problem was in the video driver of my Intel Iris Xe graphic card (built into the CPU) installed by Lenovo. I update it using the driver downloaded from Intel site and the problem disappeared. Now it works like a charm.

I purchased a Kindle Scribe (discounted).

I consider it a good reader, but a bad note-taking tool. I use it to read books without distraction. Sometimes I use it together with the Remarkable. When I need something more powerful, I use my convertible laptop.
