IMHO:
I put it on top of 8ki with customized applications (I drove 8ku for about 5 days)
1. There are no freezes on my phone.
2. In the recent manager, I did not notice such bugs with empty windows for 3 weeks of operation.
3. I changed dpi through an engineer, I didn’t really like it, I just chose a small text. In a pair of dialogs I saw a scroll on pop-ups - not critical.
4. I regard it as a plus of the system, because I can not just turn off the entire application, but can flexibly configure which types of notifications to leave. Example: in instances I can turn off live broadcast notifications, while leaving notifications from the chat. Plus, a cool wizard from the curtain immediately after switching to the notification settings will highlight which group I just saw.
5. There are no problems with my WiFi router, all the rules are at work.
Root and twrp are not. Official firmware by air. The device itself is Chinese. Oneplus 6 is my second smart on which I see no reason to set root. The first was Oneplus 3T. Before that I was a fan of root, magisk, xposed modules, custom firmware, and changed with more than a dozen phones :)
