With the arrival of Android 11 to the different OnePlus mobiles, problems have begun to surface and leave results that spoil the illusion of users. There have been several Android 11 problems in OnePlus since the first updates for the OnePlus 8T, but it is also that they remain constant between the versions that the OnePlus 7T already enjoy, as well as other models.
These incidents are nothing new, as the OnePlus forums are often full of unwanted situations after each update. However, there are usually solutions to Android 11 problems on all devices and it is that with just a little digging, we will be able to solve any problem. We go on to show you the most repeated problems and the solutions that should work for you.

The mobile is frozen
At various times of normal mobile use, users have experienced problems when setting the alarm, for example, but it has also occurred in other situations. The problem with Android 11 prevents the use of the mobile, since the screen is frozen for a few seconds without us being able to do anything about it. An error that has been creeping in and has appeared especially in the OnePlus 8.
Solution:
After several tests, users have not been able to solve it in any way, although OnePlus already knows the error and has begun to send an update that fixes it . In addition, it resolves other previous system problems that were still in effect.

You just have to go into Settings> System and click on system update. The sending of the updates is fast by OnePlus, so a new version should already appear that ends with this problem.
Photos disappear from gallery on OnePlus
One of the errors that can worry us the most is when after updating to Android 11 in OnePlus we find that there are photos that are not in the gallery and in other cases they are complete folders. OnePlus luckily has tried to fix it quickly.

Solution:
The company has not needed to send any system updates to users and I have been doing it through Google Play. Some of its main apps such as the OnePlus gallery use Google Play for updates and after this update everything is resolved.
On-screen gestures stop working
With the arrival of Android 11 and OxygenOS 11 to OnePlus mobiles, the gesture system that was one of the best-working has begun to fail. The speed that characterizes OnePlus in its customization layer has been in smoke and the failures are repeated especially in the latest OnePlus 8T.

Solution:
The problem occurs especially in those who add extra options to gestures. Therefore, if we limit the OnePlus cats to the most basic ones, such as going back, opening multitasking and going to start, we should not have problems. We will have to go with them disabled for some time until an update fixes it.

- We begin by entering Settings.
- Then we go down to Utilities.
- We deactivate the fast start.
- To finish applying the change, we restart the mobile.
The camera does not focus on nearby objects
Photography also suffers from failures in OnePlus phones with this update, especially at short distances. When trying to take pictures of smaller objects, the OnePlus 8T and other models have found that the camera does not focus. This also does not improve when using the super macro mode of the camera and we are only left with one option.

Solution:
The only way to fix it that we have so far is based on the mobile’s professional mode, where by adapting the selective focus mode we are able to achieve a good result.
Warp Charge fast charging does not work with OxygenOS 11
Countless users have found that the fast charge known as Warp Charge on OnePlus smartphones does not work as it did before the update. With the renewal of the operating system and the customization layer, users have been able to see how the charging power decreases significantly and prevents them from taking advantage of the benefits.

Despite this, we can see that the technology continues to show on the lock screen when connecting the charger, but nevertheless the waiting times increase considerably.
Solution:
After many charger tests, users of the OnePlus forum have come to a conclusion and that is that even going into the battery options and deactivating the optimized charge does not solve this. However, patience returns the best fast charge to the mobile, because after about 4 or 5 charging cycles the power returns to the desired one. Apparently after the update OnePlus tries to limit the load to learn about load patterns and improve the results.
Slow unlocking on OnePlus with the fingerprint reader
All OnePlus terminals of the last years in the high range integrate the fingerprint reader on the screen, being already a basic feature in the company. However, with the arrival of Android 11 to OnePlus there is a problem with this unlocking that prevents opting for this security system since it takes too long to recognize the fingerprint and in other cases it constantly fails.

Solution:
The culprit for this is none other than the Always On Display mode that comes to OnePlus with OxygenOS 11 after many users request it. All those who have the Always On Display mode activated have noticed how it fails more often and becomes slow, so just deactivating it will be enough: We will do this from Settings> Display> Always On Display.
Problems with calls on Android 11
There is not only one problem that has appeared around the calls of OnePlus mobiles, but there are several. Especially in the OnePlus 8 and OnePlus 8 Pro a strange phenomenon has been repeated when picking up calls, which causes the speaker to activate only at other times when the volume decreases little by little. The failure has been reported to OnePlus although now without answers.

Solution:
The only thing we can do and that seems to work for some time, is to go into Settings> Applications and locate the phone to clear the cache. With this, the problem seems to subside for a time.
How to fix other OnePlus problems with Android 11
Although we have already known most of the bugs, we are continuously learning about new errors that usually affect mobile phones with the beta and stable updates of OxygenOS . Luckily, the manufacturer offers us a fast and comfortable hermitage that tries to clean false records and therefore allows a cleaner installation of the novelties because we do not encounter so many inconveniences. The solution is called Wipe Cache and is based on the following:
- First, the mobile is turned off.
- Then the volume down and power buttons are held down until you see the OnePlus logo.
- We choose English as the language.
- Click on “wipe data and cache”.
- Now we choose “wipe cache”.
- We tap on “Yes” to confirm it.
- And to finish we choose reboot.
This solution is the same that OnePlus offers us in case of encountering a fault, as it is the one that works the most times after problems with updates.
