OnePlus 9 series users report multiple bugs after latest Oxygen OS 12 update

By Rahul Srinivas December 8, 2021

Things don’t seem to be going well for OnePlus, which recently rolled out a significant update for its 2021 flagships — the OnePlus 9 and the OnePlus 9 Pro. Initial reports indicate that the fresh Oxygen OS 12 update for both smartphones is littered with bugs. Hours after people updated their phones, they took to social media and OnePlus’ own forums to voice their concerns.

The issues range from seemingly minor ones like UI inconsistencies and poor animations to potentially crippling ones like slow Wi-Fi speeds and losing the ability to make and receive calls. The move to Oxygen OS 12 has also resulted in OnePlus removing several customization options on the OnePlus 9 series. With the update installed, users lose the ability to change individual icons, disable Google Feed, or customize the status bar.

It's official, I absolutely hate this new ColorOS update by @oneplus. It's half-assed, animations looking shitty, some apps with different DPI scaling, and reeks of chinese skin type of Android. I hate it and I can't wait to ditch this for the Pixel 6.

A OnePlus forum member listed several issues he observed on his OnePlus 9. According to him, the update has broken the task manager feature, which can no longer close all apps in the background. WhatsApp users have noticed that they are unable to use WhatsApp Web. The default phone app on Oxygen OS 12 is different from the previous OS, and it no longer offers the option for call recording.

Another OnePlus forum user claimed that his SIM card has stopped working and that even a factory reset did not fix the issue. Some others report that the phone does not connect to 5G networks anymore. There seems to be an issue with the Alarm functionality as well, with one user indicating that his phone “forgets” a preset alarm if he reboots the device.

If you own a OnePlus 9 series device, it might be a good idea to hold the urge to update your phone to the latest version of Oxygen OS 12. Given the number of complaints after this update, chances are high OnePlus will roll out a fix for these bugs in the days to come.

The future of OnePlus’ messy phone software has me worried

The OnePlus 10 Pro and OnePlus 9 Pro's camera modules.

The OnePlus 10 Pro comes with OxygenOS 12 installed over Android 12. That's the good news. The bad news is its considerable similarity to Oppo’s ColorOS 12 software, and all its inherent issues has caused controversy among the OnePlus faithful. Many are looking forward to OxygenOS 13 as the savior, but OnePlus' current messaging around it is confused and noncommittal.

But was OnePlus’s old OxygenOS software really that much better? After all, it's easy to look back with rose-colored glasses when we're faced with disappointment. To find out, I put the OnePlus 10 Pro alongside the OnePlus 9 Pro to see if the adoration for past versions of OxygenOS could be chalked up to nostalgia before we get too caught up in our expectations for the future.
What’s the problem with OxygenOS 12?
The problem with OxygenOS 12 is that it’s the same as Oppo’s ColorOS 12, and that makes it not very good. Both suffer from, based on my opinion and personal experience, two primary problems: Poor reliability and a dismal approach to design and user experience. I’ve used OxygenOS (and ColorOS and RealmeUI, which are basically the same) a lot recently, and have encountered the same problems, convincing me these are software issues, rather than “me” issues.

A OnePlus 10 with insane charging speeds might be on the way

The OnePlus 10 Pro and OnePlus 9 Pro's camera modules.

OnePlus will be launching a OnePlus 10 after all, just a month out from the debut of the OnePlus 10 Pro as a stand-alone flagship, according to a new report. While the company in the past has debuted both phones side by side, it opted against doing so this year, giving the impression that we wouldn't be seeing a OnePlus 10. However, considering the new OnePlus isn't quite the picture of restraint, a OnePlus 10 release was more likely than not.

According to a report from Digit in collaboration with trusted leaker Steve Hemmerstoffer, known as OnLeaks, the OnePlus 10 will have two separate variants depending on the system on a chip (SoC). The smartphone is said to be powered either by a Qualcomm Snapdragon 8 Gen 1 chip or a MediaTek Dimensity 9000 SoC, likely depending on the region. It seems like OnePlus is in the early stages of testing the OnePlus 10 and it hasn't locked the exact variant that will be mass-produced.

See Hasselblad’s influence on OnePlus’ phone cameras in our epic test

OnePlus 10 Pro, OnePlus 9 Pro, and OnePlus 8 Pro camera modules.

OnePlus and Hasselblad first partnered in early 2021 and since then we have seen the OnePlus 9, OnePlus 9 Pro, and OnePlus 10 Pro all arrive with Hasselblad’s name attached and its photographic expertise added to the camera’s software.

It has been difficult to really pinpoint the differences Hasselblad has made though. Armed with the OnePlus 9 Pro, the OnePlus 10 Pro, and the pre-Hasselblad OnePlus 8 Pro, we’ve taken a selection of photos to better understand how, or if, Hasselblad and OnePlus have improved its cameras.
The cameras
The OnePlus 8 Pro was the last flagship phone to be released before Hasselblad came on board. In the top-center, a stick-thin camera module hides a 48-megapixel main camera, a 48MP wide-angle camera, and an 8MP telephoto for 3x optical zoom, plus a 5MP camera for the odd Color Filter mode. The selfie camera has 16MP.
