How to Fix OxygenOS 5.0 Problems

While the OxygenOS 5.0 update is more about new features and better performance, but it indeed has brought a few minor issues with it. We are not sure if the problems that have risen are a firmware issue (bug). Or, if they are triggered at the user-end due to dirty updating (Updating without wiping).

The issues could be subjective and if you’re in trouble too, then we are confident that the tips below will help you fix OxygenOS 5.0 problems.

1. Quick Reply In Notification Panel Not Working

Instantly replying to messages from with the notifications panel is quite a handy feature. However, according to some users in the OnePlus Community forums, the ‘REPLY’ button is not responsive.

Since we have faced this issue personally, we can only suspect that it is the result of a dirty update. To fix Quick Reply OxygenOS 5.0 problems, you can either perform a Factory Reset from the Settings or make a fresh install. If you wish to perform the latter, you can follow our guide on how to manually install OxygenOS 5.0 update.

2. OnePlus Launcher Crashing

For some users, the stock OnePlus launcher has been rendering the dreaded ‘OnePlus Launcher keeps stopping’ error. Which means the launcher app is crashing either while long-pressing on homescreen, while applying the wallpaper, or just randomly.

In order to fix OxygenOS 5.0 problems related to the OnePlus launcher, you will simply need to wipe the cache (Or even Data in some conditions) of the app. You can do it by going to Settings -> Apps -> App info -> OnePlus Launcher -> Storage and tap on ‘CLEAR CACHE’.

Several users at the forums suggest that uninstalling any updates of OnePlus Launcher from the Settings and reinstalling them from Play Store has worked for them.

3. Notification Dots Are Not Appearing

Several users have been reporting about Notification Dots not appearing on app icons like WhatsApp, Instagram, etc. Though this is not an issue, we thought to include it here.

The OnePlus launcher requires ‘Notification Access’ permissions in order to scan for them and display Notification Dots in the launcher. The said permissions are disabled by default. So, you will need to go to Settings and provide the required permissions to the OnePlus launcher.

4. Random Battery Drain

This is another one of OxygenOS 5.0 problems that a majority of users have noticed. However, there are no permanent reports and the issue varies from user-to-user. Some reported of low SOT (Screen On Time), while other pointed out extensive battery consumption by ‘Cell Standby’.

Almost nobody has yet been able to provide appropriate graphs/reports on the specific issue. And at the same time, users who have made a clean install are not suffering from this issue. So the best way to fix OxygenOS 5.0 problems related to battery drain is by doing a Factory Reset after updating.

5. Recent Apps & Contact Search Not Working

A very small percentage of users claimed that Recent Apps (Multitasking window) and the Search feature in the Contacts app is not functional for them. Both of these seem to be a graphical glitch in the system.

The easiest way to get past this and fix OxygenOS 5.0 problems related to it, is by performing a hard reboot. In most situations, that should fix the problem and you shall not face it again.

6. Android Oreo’s Picture-in-Picture (PIP) Mode Not Working

Again, this is not a bug/issue with the software. OnePlus has correctly implemented the feature in the OxygenOS 5.0 update.

Users need to take note that in order for PIP mode to work on YouTube, you would require a YouTube Red Subscription. There are unofficial workarounds, but we strongly recommend that you pay for the service if you’re willing to use it.

For users who want to use PIP mode during WhatsApp calling, can simply long-press the Home button when in a call.

7. Other Issues

That’s not the end of the OxygenOS 5.0 problems on the OP3 and 3T. People have made several other claims, the majority of which are related to the battery. There were also complaints of the previous Open Beta 27/18 release updated for October 2017 patch level, while the stable release is still holding back to the September security patches.

Also, the new accent color in Quick Settings toggles and the Settings have turned down the experience for several users. Since Android Oreo natively supports Overlay Manager Service (OMS), then you can make use of Substratum to theme your device, without root.

In most cases, the cause of these problems is dirty flashing. So, we strongly recommend you perform a wipe before manual installation or do a Factory Reset after you have installed the update.

We hope, we have been able to help you fix a few OxygenOS 5.0 problems, if not all. If you are facing any other issues, mention it down in the comments. We will try our level best to find you a solution.


  1. Hi Dhananjay,

    I’m facing issues with my WiFi connection after Oreo update. It’s unstable. It connects to WiFi and in few seconds it disconnects and reconnects automatically. It affects apps which need continuous internet access like few games. I see many users have posted over various forums about facing this issue but don’t see any concrete solution to fix it. Would you be able to help out here?

  2. I have installed the new update and am unable to connect to the internet using mobile data. Have tried amending the APN settings as advised on the ID network website, by calling ID helpline and by swapping sims and settings with another phone and still no use.
    I’ve even tried installing the previous Android version and still nothing. Please help.

    1. That seems odd. How did you install the OOS 5.0 update in the first place? Like did you use TWRP or the Local Upgrade method?

    1. Hi Mohit, It seems to be an issue with OOS 5.0. Have you given a try to the latest Open Beta?

  3. My internet speed in mobile is not as earlier. After update i can just use whatsapp but not other things. Though if i use the data via hotspot in other devices then it is fast

    1. Hello Waseem, here is what I could find on the problem you stated. To fix it, you can go to the APN settings and reset the APNs. Then reboot the device and try again. Let me know how it goes.

    2. Hi Dhananjay,
      No luck. I see most of the users are facing this issue.

      Dot know how and when one plus will fix this issue 🙁

    3. The thing is, it is working fine on my colleague’s device where I tested the new update. However, I made a clean install.

      How did you update your device? and is it currently on Stable version or Open Beta?

    4. It is stable version and i have visited One Plus service center and they said the issue is common and s they downgraded my OS.

    5. Glad you got it sorted. Hopefully, the upcoming release will bring stabilization to the interface and the most basic functions.

    6. Facing the same issue here.
      I have updated today morning. My internet is not working through Mobile Data.
      through wifi it is working fine.

    7. Hello, the problem seems to be common among a lot of users. The easiest way to fix this is by resetting the APN settings. Kindly try and confirm?

  4. Hi. For some reason people cant hear me in conference calls. All they hear is a beeping sound when i speak. Works fine for one to one calls though..

    1. Hello Ajith, I just tried it and it works on my colleague’s OnePlus 3. It may be a temporary issue.
      Have you tried ejecting and reinserting the SIM card?

    1. Hi. There’s a little trick that I saw on the OnePlus forums. According to that, here’s what you can try:

      1) Power down the device.
      2) Eject the Sim try and remove the SIM card.
      3) Put in the empty tray and reboot into the system.
      4) Again, power down the device.
      5) Put the SIM in the primary slot of the tray.
      6) Then reboot back to OS.

      Hopefully, it should be working. Good luck and let me know the result.

  5. Oops i discovered this may not have been the case as i have inserted it into sim tray 2 and is now working as normal. Sorry, please delete my comments as they are likely unrelated to this update.

  6. After installing this update i find it completely fails to recognise my sim card leaving me without any network features whatsoever. I can’t make calls or anything like that, I can only use Wifi to access the Internet etc. Super doomed and i don’t know what to do to resolve this.
