A series of factors could interrupt the process when it comes to downloading or installing an app. We’ve put together a list of some of the most common issues during the installation process:
-
Not enough free storage space: You'll need minimum space storage on your Android device before installing it. At a minimum, the available space should double that of the file you want to download.
-
Permissions are not enabled: If you’re using our official Android app, you'll need to enable writing permissions. Although this option is usually enabled by default the first time you install it, certain brands or Android versions may require manual action. To do this, you have to long tap on the Uptodown App Store icon, access the information menu, and look for an option related to the "installation of unknown apps". By default, the Android operating system does not allow the installation of apps outside the official Google store, so this confirmation may be necessary.
-
Non-compatible architecture: Although most of the apps in our catalog are universal and allow their installation on any Android device, some are only supported by a specific hardware. Other than being an app that's exclusive for smartwatches or Android TV (and therefore not working on smartphones), many apps may require that the device's CPU be compatible with the ARM64 architecture. Although most current devices are, it is recommended that you check the device's technical specifications to confirm.
-
It’s an XAPK file: Although APK is the most extended packed format for Android apps, we distribute many of them in XAPK, a container format that isn’t compatible with Android's default package installer. Our official Android app allows you to install them easily. We recommend referring to the How to install an XAPK file guide.
-
Insufficient Android version: Although Uptodown does not limit the download in any way, certain apps are subject to minimum recommended requirements that, if not met, could cause errors both during installation and in the game. Please check these requirements in the technical information table provided on the app's download page.
-
Unstable connection: If the file download is performed using mobile or weak WiFi networks, it may get interrupted, making the resulting downloaded file incomplete and therefore impossible to install. Please, check that the size of the downloaded file matches that specified on Uptodown's download page. If not, please restart the installation.
-
Incompatibility with certain manufacturers: Some devices that use the MIUI customization layer (Xiaomi, Mi, Redmi, etc.) may present problems when installing apps from unknown sources. There is a way to avoid it described in the section How to avoid errors when installing apps from Uptodown on Xiaomi devices.
-
Uptodown failure: Although we perform all possible checks, our servers may have problems for short periods of time. If the problem persists after a few hours, please contact our support team and we will try to solve it as soon as possible.
