OnePlus have replaced the 65W power brick with an 80W power brick that is no longer PD compatible if you're in Europe and India. The US still gets the 65W PD compatible power brick. Additionally the wide angle camera has been downgraded both in terms of sensor size and functionality as it can no longer take macro shots.

https://www.gsmarena.com/the_scrolling_on_the_oneplus_10_pro_is_bad_and_oneplus_should_feel_bad-news-54115.php

TLDR: The phone exhibits massive stutters and delays when scrolling in certain apps because OnePlus have fucked up dynamic refresh rate system.

OnePlus is paying websites to talk about the design and gaming credentials of the 10R.

The software is bad, it it stutters because they've implemented dynamic refresh rate poorly. There's also a weird mismatch of ColorOS and previous OxygenOS elements.

The phone is made of plastic (while the cheaper Nord 2 has a glass back),

The camera is garbage.

TLDR: They've recommended buying other phones at that price point instead.

The same phone is sold in China and seems to have a problem with overheating.

You know things are bad when the media starts to criticise OnePlus.

OnePlus have changed the notification shade and status bar icons on the latest beta of Android 13. They were the last remnants of OxygenOS, unsure why they aren't just calling it ColorOS now.

The sub brand has another sub brand.
