like other reviews my notes 20 ultra will not automatically detect and switch to the best network node, even when the current connection becomes very poor. I've tweaked the network settings on the phone and the results are always the same. this year is not present on any of our other home networking devices and we have a powerful mesh networking kit with wired back haul that creates six available 5G WiFi bands in the home. the phone does not automatically switch to a wireless LTE or 5G signal either even when smart switching is enabled. I tried disabling Wi-Fi scan throttling and there was no improvement. as others have stated the only way to get the phone to recognize and switch to the highest quality signal is to toggle the Wi-Fi setting off and on. Samsung please realize that this is more than a triviality but is an actual problem for users that are on the move. for instance I have to do video calling and conferencing and move between multiple locations during a call. in other networks I've noticed the same problem. this makes the phone virtually useless for mobile video conferencing in regions where Network conditions change frequently. ...

so far, the RAM usage on my new note 20 ultra is no more than ~10 GB but only that high when using Dex. I was sort of surprised when I saw that projecting to a smart TV would utilize so much memory. do you think that the phone would run well if it was being used in dex mode and being wirelessly charged at the same time? I wouldn't want to overheat it when being used in this way over a longer period of time. ... View more

I disagree with your opinion because running into high RAM use is possible for Dex users. you're right that there's no need for a high RAM configuration for using the phone in regular use. someone using dex while streaming lectures, recording, and taking notes all at the same time - something many college students have a need for - means that 16 gigabytes of RAM is not a niche use case. ...
