4 common OnePlus 12 problems and how to solve them

Launched in January this year, the OnePlus 12 is a smartphone of Chinese origin with high processing power due to hardware such as 12 GB RAM and the Qualcomm Snapdragon 888 processor. But, in addition to the high popularity, some users shared some dissatisfaction with common problems on this cell phone.

Next, find out what some of these problems are and how to solve them on the OnePlus 12. Suggestions range from changing the smartphone's native settings to using other devices.

Persistent fog on camera

During cold climates and high humidity, some users have noticed that a light spot appears on the device's camera, almost like a fog, which compromises the act of capturing images and filming. Necessarily, this is a problem that must be addressed with the customer service from the brand, however, while you wait for a response, you can try another method.

When this happens, it's usually because part of the camera cover isn't properly fitted, so the first thing to do is check if you can fit it in properly by applying a little pressure. If this is not enough, place your cell phone on an air dehumidifier and leave the cell phone recording for 30 minutes at the highest resolution possible. This set of factors can help evaporate moisture inside the camera.

This was just a suggestion, but we recommend that the best option is to visit a technician authorized by the smartphone manufacturer and take the device for repair.

Cell phone only chooses the slowest internet network

Some more modern devices are already programmed to automatically access the fastest internet network available. For example: if your router broadcasts two bands simultaneously, such as 2G and 5G, the smartphone would connect to 5G. But this doesn't always happen.

The first thing that should be done is to turn off the Wi-Fi on your OnePlus 12, wait a few seconds and turn it on again. If it has not connected to the 5 GHz band, then the first step is to change the router's configuration so that it only outputs the highest speed: you can do this by contacting the machine's technical assistance. And if even that doesn't work, try updating the router's firmware.

Gmail freezes on mobile

Having 12 GB of RAM is a privilege, however, some devices don't know how to use it properly — either because of a factory defect or because the manufacturer didn't do a good job when developing the device. In some online forums, there are many reports of the Gmail app freezing on the OnePlus 12 and this certainly has to do with RAM management.

RAM memory can be considered the processor's “best friend”, as it helps it stabilize countless processes. Despite this, when this memory is relatively large, it ends up being responsible for many tasks, which can lead to a lot of crashes; but, as we have already warned, this is not common in devices that have been well developed.

Therefore, our suggestion is the following: access your smartphone's settings and adjust the OnePlus 12's RAM memory expansion: change it from 12 GB to 4 GB. Also, try deleting the Gmail app and installing it again. These changes should resolve excessive app freezing.

Refresh rate suddenly drops

The refresh rate of a screen is equal to the number of times per second that the screen updates images: the higher the rate, the smoother the viewed content is rotated. In the case of the OnePlus 12, its refresh rate is 120 Hz, which should be very good for those who value gaming.

However, after a certain amount of playing time, it is possible to notice that the images begin to have a lower quality in terms of fluidity and movements, and even present certain crashes. This drop in the refresh rate occurs because the cell phone system has detected a worrying level of increase in temperature, so reducing the rate can help stabilize the temperature.

This feature is automatic and does not represent a defect. Despite this, you can make some changes to your cell phone and your environment so that you can continuously enjoy the 120 Hz rate. First, activate the “pro game mode” in the Hyperboost function so that the cell phone remains performing well. Then, move away from exposed sunlight and stand in front of a fan or in an air-conditioned room.

It is also recommended that you avoid playing while your cell phone is charging.
