Download and Installation

Why can't I find a suitable version for my phone on wap.ucweb.com?: Because mobile phone models change so fast, our download platform can't always be up to date. We recommend that you download the .jar or .jad files to install. If these files can't be installed, for example, you can only get "???" displayed on your phone, or you can only do certain operations like "Delete” or “Send", or you get notifications that your phone can't support these files, then it means your mobile phone doesn't support Java. You are unable to install Java applications, including UC Browser.
Why can't I install UC Browser or why does it show an error message "certificate error" in the installation?: Please go to Menu > Settings > Application Manager > Installation Settings; set the option of Software Installation to be "All", and set the Online Certificate Check to be Off.
Why have I received a notification that there is no certificate in SIM?: You have to make sure that your phone is certificate-supported if you want to use the signed version. This notification is usually caused by the fact that your phone doesn't support certificate versions. You should download the universal version.
What do I do if it says "certificate expired" during installation?: Please set the system time of your mobile phone to be the current time, and download the signed version browser on our official site (wap.ucweb.com).
Why it is always connecting to network when I start the browser?: Firstly, check your network. If there are some problems with your network, change the access point. If the network is fine, then it is because your phone's memory is insufficient. You need to release some memory by deleting some applications in your phone. Or you can try a smaller sized version, like 7.2 Lite.
Why does the browser always need to initialize each time I open it?: First, check your network. A network problem will affect the operation of UC Browser. If the network is fine, then it is because your phone memory is insufficient. Its recommended you periodically clear your cache, decrease the quality of the images, turn off page segmentation, and delete some unnecessary applications on your phone. If the problem persists, please use a smaller sized version of UC Browser.
Why does it ask for connecting permission each time when I start the browser?: If you are using the signed version, please edit the permission: find UC Browser in applications, put the cursor on the icon (don't click it). Press the left button and go to Application Access > Communication > Network Access, and set it as Ask First Time Only.

Images

Why are gif images not shown?: If the gif image is shown in static, please set the image quality to normal, change Website Preferences, change the WAP Access via Server setting and clear your cache. If the problem persists, please provide the link URL for our reference.
Why are images loading so slow?: This is probably caused by a bad network condition. Please change the network environment and try again. You can also try to decrease the image quality via Menu > Settings > Display > Image Quality and set WAP Access via Server to On.
Why isn't an image displaying?: First check if the image isn't missing or broken. If so, check whether this problem only occurs on this one webpage or on all sites. If this problem occurs on all sites, check whether "Text-Only" is on or off. If it is On, please turn it off and try again. If this problem occurs on this one webpage, please provide us with the specific link URL. If the image is broken, try to change the image quality, your access point, enable/disable WAP Access via Server and clear your cache.
How do I view an original image?: The function of original image is only for images compressed by our server. You can long press the image and choose Image View > Original Image. Because some of the images are not compressed by UC's server, you won't be able to do this for all images.
Why isn't CAPTCHA being displayed: Make sure "Text-only" is off. If it is off and this problem persists, for some WWW sites CAPTCHA is displayed in flash format. Since the browser can't support flash, the image can't be displayed. For WAP sites, try to decrease the quality of images or enable/disable WAP Access via Server. If the problem persists, please let us know the URL.
Why can't I download images from Facebook?: First make sure you are logged in Facebook. If so, try to change the size of segment, enable/disable WAP Access via Server, and change the saved path. If the problem persists, please provide your phone model, version No., access point, ID, SN, and the page URL to help us solve this problem.
Why I can't upload images to Facebook?: This is probably an issue with Facebook's website. If this problem persists, let us know.

Networks

Why do I always get a network access notification every time I click a link?: If you are using a Nokia S40 phone, please change the following settings: Find UC Browser in applications, put the cursor on the icon (don't click it). Press the left button and go to Application Access > Communication > Network Access, set it as Ask First Time Only.
Why can't I connect to the network after installation?: First check whether the network is normal on your phone's built-in browser. If you can't connect to the network via your built-in browser, please consult your network operator.
This problem is probably caused by incorrect network settings on your phone. Different applications may require different network settings. If the network settings are incorrect, some of the applications may have a connection failure problem. Try to adjust the network settings on your phone.
Why is the network speed is so slow?: Enable WPA Access via Server, then test the network speed on WAP sites and WWW sites, then check the network speed when you are using other applications. If they are both slow, then it means the local network speed is slow. If network speed on WAP sites are not slow while that on WWW sites are slow, then it means that the network speed of our severs is slow.
You can also try to clear the cache and data like data on clipboard, history and bookmarks to release some space. Or you can remove some of the applications on your phone to release some memory.

Browser Running

Why is the browser's response so slow?: Usually this problem is caused by the low memory of your phone. Try to decrease the quality of images and regularly clear the cache and data, such as data on clipboard, history or bookmarks to release more space. Don't install too many applications on your phone. If the problem still exists, please try using the Lite version.
Why does the browser exit automatically or have a black screen?: Usually this problem is caused by the low memory of your phone. Try to decrease the quality of images, regularly clear the cache and delete some unnecessary data, such as data on your clipboard, or your history and bookmarks to release more space.

If you can't download a specific file, please try to download it by using your phone's built-in browser. If you can download it via the built-in browser, and not by UC Browser, please provide the download link for us to test.
Why do I get a notification about "permission of user data" when downloading?: For this problem, you can modify the permission like this: Find UC Browser in applications, put the cursor on the icon (don't click it). Press the left button and go to Application Access, find the settings of Read User Data and Edit User Data, and change their options from "Not Allowed" to be "Ask Every time" or "Ask First Time Only".
Why can't I choose the download path?: A. If you are using a Nokia phone, try this: Find UC Browser in applications, put the cursor on the icon (don't click it).

B. If you are using a Motorola phone, you need to assign permission to download the files normally.
Why can't I choose the saved path when downloading files? I get a notification when I try to choose the saved path, but can't choose "Always Allow". All the options are set to "Not Allow" as default when trying to change the settings.: If your phone is certificate-supported and the UC Browser you downloaded is usually without a certificate, then this problem occurs. Please go to http://wap.ucweb.com to choose by your phone model, and choose Signed Version for Java to install.

Why do I get a notification about file creation failure?: This problem is caused by the fact that your phone doesn't support the jsr75 file system. See if you can view files inside your phone by Menu > File > File Manager in UC Browser. If you can't, then it means that your phone doesn't support the jsr75 file system.
Why can't I download a file over 5MB?: Check if you have this problem with your phone's built-in browser. If there isn't, make sure that there is enough memory to download this file, and then try to change the segment size, enable/disable WAP Access via Server, and saved path.

Disable WAP Access via Server and enable WAP preload, then you can use Reader after you log into a WAP site. You can use Reader for WWW sites on UC Browser for Java and Android phones, but this function will be only available for forums and novels of WWW sites.
What is the function of WAP Access via Server?: When WAP Access via Server is enabled, UC servers will compress and re-compose the webpages you visit to accelerate Internet speed and reduce data usage. This function is only available for WAP sites. If you encounter problems when visiting WAP sites, Go to Menu > Settings > Browser to enable/disable WAP Access via Server. For Android 8.0 or higher, please enable the function of Cloud Acceleration.
