How To Reset Chrome Sync To Fix Problems

Google Chrome is excellent at syncing browser data between desktop and mobile devices. The integrated Chrome sync functionality, which helps make that happen, works efficiently behind the scenesn.

Over time, though, you may run into issues where Chrome fails to make your browsing data available across devices. In such instances, resetting Chrome sync is a fix that can help.

Table of Contents

What Happens When You Reset Chrome Sync

Chrome uses the Google servers to upload and sync changes to browsing data among devices. A Chrome sync reset allows you to start again from scratch.

The reset starts by deleting the browser data stored within Google’s servers. It then logs you out of Chrome on all your devices. This disables Chrome sync everywhere.

Chrome assumes the data present on the first device that you sign in with as the most recent. While you can use any of your devices to reset Chrome sync, you must enable it again on a device that contains a complete version of browsing data. If not, you may end up syncing obsolete data among devices.

Why You Must Reset Chrome Sync

Below, you can find several scenarios that can call for a Chrome sync reset.

You Can’t Sync Your Data Between Devices

If you are sure that you’ve set up Chrome sync correctly, you can try resetting it to set things straight. After deleting the data online, sign back in with the device that has your most recent browsing data.

You Keep Running Into Performance Issues

Do you keep running into performance issues in Chrome? If you’ve already gone through the recommended troubleshooting fixes for Chrome crashes and freezes, you can wrap that up by performing a Chrome sync reset.

You Forgot Your Sync Passphrase

A sync passphrase allows you to encrypt the data on the Google servers. That prevents anyone from reading your browsing data if you end up compromising your Google Account credentials. 

If you forget your sync passphrase, however, you can’t sync your browsing data to newer devices. In that case, a Chrome sync reset can help you get rid of it. You must also do that if you want to change your sync passphrase.

You Deleted Passwords or Bookmarks Accidentally You Have Privacy Concerns

Do you feel uncomfortable having your browsing data stored on Google’s servers? If you want to stop using Chrome sync altogether, resetting it can help you get rid of the online data. Aside from that, you may also want to look into deleting your Chrome web activity.

How to Reset Chrome Sync

Resetting Chrome sync is a straightforward affair. You can perform it on any device (desktop or mobile) that you’ve signed into with your Google Account. You do not have to repeat it on other devices.

Desktop (Windows/macOS)

1. Open the Chrome menu and select Settings.

2. Select Sync and Google services.

3. Select Review your synced data.

4. Scroll down the Data from Chrome sync page and select Reset Sync.

5. Select OK.

Mobile (Android/iOS)

1. Open the Chrome menu and tap Settings.

2. Tap Sync and Google services.

3. Tap Manage Sync.

4. Tap Manage synced data (Android) or Data from Chrome sync (iOS).

5. Scroll down the Data from Chrome sync page, and tap Reset Sync.

6. Tap OK.

How to Enable Chrome Sync

After you’ve reset Chrome sync, you can sign back in and reactivate it on your devices. Since you’ve already signed into the browser previously, you do not have to re-enter your Google Account credentials again.

Desktop (Windows/macOS)

1. Select your profile icon to the right side of the Chrome address bar.

2. Select Turn on sync.

3. Select Yes, I’m in.

Mobile (Android/iOS)

1. Open a new tab and tap the profile icon to the top-right of the screen.

2. Tap Sign in to Chrome.

3. Tap Yes, I’m in.

Windows Audio Device Graph Isolation Has High Cpu Usage? Here’s How To Fix It

Windows Audio Device Graph Isolation, identified as Audiodg.exe, is a background process to handle distinct sound effects in Windows. This service is isolated from the actual audio service of Windows to improve audio stability. But sometimes, it runs into a problem and begins to consume a higher CPU.

Generally, this process should consume no more than a few percent of your CPU, but processing the digital audio signals can sometimes go complex and cause higher CPU usage. With higher CPU consumption, the processing power of the CPU will not be enough to handle other applications making your PC slow.

In this article, you will learn how to fix if the Audiodg.exe process has high CPU usage.

Here, we have compiled a list of 7 fixes you can use to solve the high CPU usage of the audio device graph isolation process.

Most of the time, when the Windows Audio Device Graph Isolation process has a high CPU usage, it has been found that a virus has camouflaged itself as the legit Windows services and runs in the background. This process is not harmful on its own.

If you are confused about if the process actually is consuming a high CPU or is the virus, you can perform a virus check and see the legitimacy of the process.

Follow these steps to check if the process is a virus or the legit one:

If you find out that the process is created by a virus, you need to remove it as soon as possible to be safe from potential threats. If you have an antivirus installed on your computer, run a full scan of your computer. It will help find and remove the virus from your computer. 

You can also run a built-in scanner on your Windows if you don’t have one. Here’s how:

Cortana is an AI-based virtual assistant service provided by Microsoft on Windows computers. Based on your voice commands, it can help you do a bunch of tasks like answering your questions, opening applications on your computers, and setting alarms.

Since this is also an audio-based service, it can also be the reason for high CPU consumption. Many users even reported that Cortana ate up their CPU to 30%. The same might be the case for you, so you can try disabling it.

You can not uninstall it since it’s an in-built service on Windows, but you can disable it.

Audio enhancements are audio packages like Bass Boost and loudness equalization installed on Windows which help the output audio from Windows sound better.

Since it is responsible for increasing the quality of sound, it is obvious that it consumes more CPU for audio processing. If you have enabled any of them and started seeing that the audio process started consuming a lot of resources on your PC, you can try disabling them and checking back to see if the CPU consumption returns to normal.

Follow these steps to disable audio enhancements on your Windows computer:

Windows uses sample rate and bit depth to define the sound quality it produces. There are basically two types of audio quality you can choose on Windows 11, namely CD and DVD quality. Earlier versions of Windows can have other options as well.

Using higher bit depth and sample rate on your PC requires larger processing that can consume a higher CPU. Consider setting them to a lower value and check if the audio process still consumes a lot of CPU.

Here’s how:

Audio drivers are a small piece of program that acts as communication agent between your operating system and audio devices like sound cards and speakers. If those drivers are outdated, it badly affects your computer’s audio performance. The Audiodg.exe process has to struggle to give the optimum performance, resulting in high CPU usage.

Therefore, you must keep the audio drivers up to date for ideal performance.

Here’s how to update audio drivers on your computer:

You can also try running the built-in audio troubleshooting tool on Windows to figure out the cause. It will find and show you if any audio-related errors are causing the high CPU usage. You can choose what action to take after looking into the issue on the troubleshooter.

Follow these steps to run audio troubleshooter on your computer:

Most of the users reported that the audio process was consuming high CPU when they were using video-calling applications like WhatsApp and Skype. If you are using any of those applications, they are resource-intensive apps and can cause CPU overuse. Consider uninstalling them and checking if it solves the problem of high CPU usage.

Oneplus 6 Problems And How To Fix Them (Updated)

Note: Not every user will come across these issues. In fact, your OnePlus 6 may not face any problems at all.

The best option is to disable auto brightness and manually set the display brightness using the slider in the notification drop down or the Settings menu.

You can also download and use the Lux Auto Brightness app available on the Google Play Store, which is an excellent tool to control the auto brightness feature.

Notifications don’t show up

A few users have found notifications don’t show up or are automatically removed after a while.

Potential solutions:

Users have found the latest Samsung Pay plugin is what is causing the problem. Reverting to an older version seems to work. You can find the older versions of the plug-in at APKMirror. Hopefully, Samsung will fix the problem in its next update.

Call and mobile data connectivity issues

One of the most common OnePlus 6 problems concerns call and mobile data connectivity issues. There is no solution or workaround available, save for performing a soft reset. At least some of these problems will be addressed by OnePlus in the next software update:

Call drops – Many users are dropping calls when using the OnePlus 6. This doesn’t seem to be limited to a particular region or network carrier either — it’s happening across the globe. Wiping the cache partition might help. You can find the instructions on how to do so below.

Missed calls – Users are getting missed call or voicemail alert notifications but the phone doesn’t ring before that. The phone isn’t set to silent or do not disturb mode.

No data connectivity – Users are seeing a full signal on the phone, but the data connection doesn’t seem to work. Toggling the data on and off or switching to Airplane mode and disabling it seems to do the trick, but this issue comes back often. Many users find this problem occurs numerous times a day.

Calls continue after hanging up – This one is a doozy. Some users have found they can still hear the person at the other end of the line after hanging up. The only way to fully end the call is to restart the device. This is one of the biggest OnePlus 6 problems for users that have come across it and should be addressed by OnePlus immediately.

Cannot be heard during calls – Users have reported that the person at the other end of the line isn’t able to hear, or are unable to hear the other person. The only option is to hang up and call the person again. This bug has been acknowledged by OnePlus and will hopefully be fixed soon.

Connectivity issues

Connectivity issues are quite common in new devices, and the OnePlus 6 no exception. Below are the general steps you can follow when facing problems with connecting to Wi-Fi or Bluetooth devices. Wi-Fi issues seem to be particularly prevalent with this device.

Potential solutions:

Wi-Fi Issues

Turn off your router and phone, and wait for a while before turning them back on.

Go to the Wi-Fi settings on the device and forget the preferred network. Enter the details again from scratch.

Check the level of activity on your current channel with the Wi-Fi Analyzer application. If necessary, simply switch to a different channel.

Disable Power Saving Mode through Settings. 

Bluetooth Issues

Make sure no power saving mode is enabled.

Tur your device’s Bluetooth off and back on again.

If the problem continues, clear the cache for Bluetooth by going to the Bluetooth Settings.

Restart the phone after clearing the data and cache.

If the Bluetooth device saves multiple profiles, you might have reached the limit for the number of profiles it can save. Delete old and unused profiles, and try setting up the connection once again from scratch.

Display more notification icons in the status bar, when reducing the display size setting has created more space before the notch. The three overflow status bar dots will also be fixed.

Increased notification and ringtone sound volume.

Rear camera autofocus improvements. This is another one of the major OnePlus 6 problems that have been reported.

Restore status bar battery percentage option. Many users have complained about the battery percentage number not being available.

The Scheduled Do Not Disturb feature will be added in the next update.

Double tap to wake issue – Some users have found the double tap to wake feature doesn’t work as expected, requiring multiple taps before the device responds. This seems to occur particularly if the phone has been idle for a while. This problem could be related to the aggressive battery optimizations and Doze feature.

Selfie portrait mode – OnePlus has confirmed a portrait mode with the front-facing camera is in the works, to be available in a future update.

Display/UI overlap – There have been multiple reports of UI overlap, where parts of the display are cut out, making key areas of apps inaccessible.

Other camera issues – While the autofocus issue will be addressed in the next update, there are a few other camera problems as well. Some users have found the Panorama mode doesn’t work very well and that the scene is extremely dark when trying to capture slow motion video.

Guides – Hard reset and wipe cache partition

Hard Reset (with the phone on) 

Open the Settings menu.

Scroll down and find Backup & Reset.

Tap on “Factory data reset.”

Select “Reset phone.”

Tap on the box that says “Erase everything.”

The device should automatically reboot.

Hard reset (with the phone off) 

Turn your phone off by pressing down the power key for five seconds.

Press and hold the volume key and power button simultaneously until the device vibrates and opens the Recovery menu.

Choose your preferred language.

Reboot the device after this is done.

Wipe cache partition

Turn your phone off by pressing down the power key for five seconds.

Press and hold the volume key and the power button simultaneously until the device vibrates and opens the Recovery menu.

Choose your preferred language.

OnePlus is admittedly off to a rocky start with its latest flagship smartphone. Users are running into quite a few OnePlus 6 problems and bugs. However, OnePlus does a great job listening to community feedback and addressing issues as quickly as possible.

If you have come across any other concerns, you can submit them to OnePlus here and a fix for your problem will hopefully be available soon.

The 5 Biggest Problems With Big Sur And How To Fix Them

Installing macOS Big Sur on your Mac grants you access to a handful of new features, design improvements, and a bunch of system customization options. Big Sur may be the best operating system ever released by Apple, but there’s one thing it shares in common with previous macOS versions: imperfection.

No operating system is perfect, but Big Sur seems to have an enormous amount of bugs and problems. This is quite understandable, though—it’s a relatively new OS. In this article, we compile five common Big Sur issues encountered by many Mac users. You’ll also find several ways to get the issues fixed.

Table of Contents

Note that while some of these problems with Big Sur have been fixed in subsequent updates, others still very much exist. In fact, bigger problems may emerge at a later date. For the unfixed/existing problems, however, we’ve provided some brilliant workaround that helped other Big Sur users experiencing similar problems.  

1. Screensaver Bug

Putting your Mac to sleep (close the lid or press Command + Option + Power button) will dismiss the screensaver, but only temporarily. Try the recommendations below to put a stop to the screensaver glitch.

Disable Fast User Switch

We should mention that this bug majorly affects Macs with multiple user accounts. Creating a new user account on your Mac running Big Sur may also birth this issue.

Apparently, it appears that the “Fact User Switching” feature is responsible for this error. Disabling the feature in System Preferences and removing it from the Menu Bar and Control Center can fix this problem.

2. Enter your Mac’s password to proceed.

3. Uncheck this option: Show fast user switching menu as.

5. Select Fast User Switching on the sidebar and uncheck these two options: Show in Menu Bar and Show in Control Centre.

Update Your Mac (to Big Sur 11.2)

The screensaver interruption glitch seems to be peculiar to the first build of Big Sur. Subsequent point releases of the operating system—particularly Big Sur 11.2 or newer—ship with fixes to the bug.

2. Battery Drain Issues

Several Mac users reported significant battery drainage after upgrading to macOS Big Sur. We also found a couple of users experiencing random battery discharge when their Mac is powered off or in sleep mode.

Before we list some solutions to these problems, you should note that sometimes, battery drainage is normal after a software update. That’s because several processes run in the background to acclimate your Mac to the new operating system.

These processes consume a lot of power but they only last a couple of days. The issue should resolve itself in about 2-5 days and battery usage should return to normal. If the battery drainage persists beyond this period, there’s probably a problem with your Mac’s battery calibration. Try some of the methods below to fix the problem.

Recalibrate Your Mac’s Battery

MacBooks undergo a calibration process that helps to estimate how long your battery would last on its current charge level. A system update can mess with your Mac’s calibration routine and cause the battery to drain faster than it’s supposed to.

To recalibrate your battery, use your Mac till the battery discharges completely and shut down. Wait for a couple of minutes and charge your Mac till the battery gets a full charge (i.e. 100%). 

Reset SMC and NVRAM

Resetting your Mac’s System Management Controller (SMC) and NVRAM (Non-Volatile Random-access memory) can help put a stop to macOS Big Sur battery drainage issues. To perform an NVRAM reset, shut down your Mac and turn it back on. Press and hold these keys as soon as the Apple logo comes up on the screen: Command + Option + P + R. Release all four keys after 20 seconds.

The SMC also controls how your Mac manages power, battery, and other related functionalities. The procedures involved in resetting the SMC vary and mostly depend on the type of processor your Mac uses. Refer to this guide on resetting SMC on Mac or visit Apple’s Support page to learn more. 

Update Your Apps

Running outdated applications on a new operating system can affect your Mac’s performance. We found that some users stopped experiencing random battery drainage on Big Sur after updating their applications to the latest versions.

For apps that aren’t on the App Store, head to the apps’ Settings menu or the developer’s website to check for available updates.

3. Mac Not Detecting External Displays

If your Mac no longer recognizes your external monitors (via USB-C hubs or adapters) after upgrading to macOS Big Sur, or it won’t detect more than one external monitor, you’re not alone.

There are hundreds and thousands of external display-related complaints in this Apple Communities thread. Several users also pointed out that Mac doesn’t project the highest resolution (particularly 4K) to their external display after the Big Sur upgrade.

Currently, there’s no official fix for this problem—even on Big Sur 11.2. Common troubleshooting steps for resolving USB and display issues (e.g. resetting the SMC and NVRAM) yield no positive result, either. The tricks below helped some Mac users get around this annoying Big Sur problem.

Hold Down Option on Scaled Resolution

One quick fix you can try is to first head over to the Display page in System Preferences.

As you can see, I now have the option for the full 6K resolution that my Pro XRD display supports. Up till now, I was running at 3K. You should see the option here for the highest resolution your monitor can support.

Thanks to Jorg Brown, a Switching to Mac reader, for sending me this tip!

Switch or Downgrade Monitor’s Input Standard

If your USB-C adapter has both HDMI 2.0 and HDMI 1.4 ports, connecting the external display to the latter may force macOS to offer the highest resolution. For DisplayPort connections, try downgrading the monitor’s input to DisplayPort 1.2 from DisplayPort 1.4.

It seems that macOS Big Sur isn’t fully compatible with the newest versions of these display standards. Hence the reason why your Mac won’t detect external displays or project content in UW-QHD (3440 x 1440p) and 4K resolutions.

For USB-C monitors, try switching the cable to a USB 2.0 port. That worked the magic for some users, so try that and check if your Mac now detects the monitor’s native resolution. If the problem persists, restart your Mac and try again.

4. AirPods Auto Switch Issues

With the “Automatic Device Switching” feature, your AirPods should switch between your iCloud devices—depending on which one’s actively playing audio. On Big Sur, AirPods will automatically switch from Mac to other iCloud devices (iPhone or iPad) but won’t switch back to the Mac. This describes the plight of many Mac users running Big Sur.

This issue is yet to be fixed in any Big Sur updates but some users revealed that signing out of Apple ID and signing back in resolved the problem—although temporarily.

Reconnect your Apple ID and check if your AirPods now switch back to your Mac from other iCloud devices.
