UC Browser common issues, and how to fix them

uc browser issues

Yeah, Chrome comes pre-installed, and most people will stick with it for the mere fact it’s a first-party browser. However, if you scratch under the surface and take some time to find an alternative browser, Google Play Store is full of viable choices. One of the best is the UC Browser. However, the same applies to all, they’re flawed, and they’ll cause you a headache from time to time. We made sure to provide list of UC Browser common issues.

Although great, UC browser has its ups and downs, and we decided to focus on the latter and help you out resolving the most common errors in UC Browser.

  1. UC Browser Download error
  2. UC Browser crashes
  3. Out of space error in UC Browser
  4. UC Browser not connecting to the internet

1. UC Browser Download error

One of the common errors users frequently reported concerns the downloads. Seemingly, they’re abruptly stopped and users are sometimes able to continue downloading while other times they need to restart the download from a scratch.

We made sure to provide you with a few solutions for this problem, so make sure to check them out below:

  • Disable Battery Optimization for the UC Browser:
  1. Open Settings.
  2. Choose Apps & notifications.
  3. Expand Advanced and choose Special app access.
  4. Open Battery optimization.
  5. Select All apps.
  6. Find UC Browser, tap on it, and choose Don’t optimize.UC Browser common errors and how to fix them 3
  • Clear the app’s cache and data:
  1. Open Settings.
  2. Choose Apps & notifications.
  3. Open All apps.
  4. Find UC Browser, open it, and select Storage.UC Browser common errors and how to fix them 4

  1. Open Settings.
  2. Choose Apps & notifications.
  3. Open All apps.
  4. Find UC Browser, open it, and select Data usage.UC Browser common errors and how to fix them 7
  5. Toggle On Background data and Unrestricted data usage.

2. UC Browser crashes

Another common problem, especially on some previous iterations of UC Browser for Android, is the app crashing. The app would work just fine until it crashes so users had to hard close it and start it again.

This is, seemingly, not as present on the current stable version, but that’s not a rule of thumb. It can happen from time to time, and we surely want to avoid it.

If you’re unsure how to deal with the frequent crashes of the UC Browser, follow the steps below:

  • Clear apps cache and data.
  • Reinstall the app.
  • Make sure all necessary permissions are granted:
  1. Open Settings.
  2. Choose Apps & notifications.
  3. Open All apps.
  4. Find UC Browser, open it, and select Permissions.UC Browser common issues
  5. Toggle On Phone and Storage permissions and exit.
  • Install older iteration of UC Browser via the APK:
  1. Uninstall UC Browser.
  2. Open Chrome.
  3. Navigate to the APKMirror and choose one of the available APKs.
  4. Allow Chrome to install the APK from an unrecognized source.
  5. Install the app and it should work much better than the troublesome latest version.

3. Out-of-space error in UC Browser

Android users tend to use their smartphones as mobile computers, and that includes storing a lot of multimedia files. Because media files are getting larger and storage is getting larger at a slower pace, there’s an obvious need for external storage. However, that’s where some UC Browser issues start.

Android is kind of limiting third-party apps’ access to the SD card. With that in mind, we can move to the next error which is the “Out of space” error in the UC Browser. If you’ve meddled with the browser settings, we suggest checking permissions and restoring the factory path for future downloads.

Here’s what you need to do to solve the issue at hand:

  • Change the default download location to internal memory:
  1. Open UC Browser.
  2. Tap on the bottom navigation bar and open Settings.
  3. Tap on the Default Path and choose a different path.UC Browser common issues
  4. Confirm changes and restart the browser.
  5. Try downloading files again.
  • Make sure you have enough storage space.
  • Clear the app’s cache and data.

Later on, if you need to have your downloads on the SD, you can transfer them manually. Just let them download on the download to internal memory first.

4. UC Browser not connecting to the internet

Now, what would you do with a browser without an internet connection? Not anything useful. And, like with any other mobile browser, UC Browser can run into some local or general network issues.

Most of the time, the problem is in the network itself. And you can easily pinpoint the culprit by trying some other browser (Chrome should do). If you’re still unable to connect, we suggest following the steps below:

  • Restart your device.
  • Turn off Wi-Fi and turn it back on.
  • Reset Network Settings:
  1. Open Settings.
  2. Choose System.
  3. Select Advanced and then Reset options. UC Browser common issues
  4. Tap on Reset Wi-Fi, mobile & Bluetooth, and reset network settings. This will erase all saved SSIDs, Bluetooth pairings, and APN configurations.

On the other hand, if Chrome does connect but UC Browser is still showing the “No network” error, make sure to try some of these steps:

  • Clear the browser’s cache and data.
  • Reinstall UC browser.
  • Enable Data usage in the background
  • Check Battery optimization for the UC Browser.

And, on that note, we can conclude this article. If you’re still stuck with any of the errors, make sure to tell us in the comments section below. We’ll do our best to help you out.
