We are aware of an issue where some users receive a "Device not compatible" error message in the Google Play Store when trying to download Instagram, even though Instagram should support the device. Google is currently investigating this issue with the Google Play Store.

As a temporary workaround, Google suggests clearing the Play Store's data from your device and then attempting to install Instagram. To do this, go to Settings > Apps > All > Google Play Store > Clear data.

If this workaround does not resolve your problem, please complete this form.

If you're trying to update or re-install Instagram and the App Store "Install" button is untappable (in gray), try connecting your device to your computer and syncing your apps via iTunes.

If these troubleshooting steps do not help, please contact Apple support.

Sometimes, when installing a new update from the App Store, something in Apple's updating process goes wrong and reboots the device. When the device reboots, it can go through a cleanup process which can take a while to run. The longest we've seen it take is 30 mins or so. Unfortunately, the whole installing/rebooting process is all in Apple's iOS, and is out of Instagram's control.

If you've waited for the device to reboot but it's still not working, you may want to:

• Wait until it runs out of battery and try booting
• Try different combinations of plugging the phone in / restarting the computer with the phone plugged in / unplugging and re-plugging the phone

If these troubleshooting steps do not help, please contact Apple support.

If you are having issues downloading the Instagram application from the Google Play marketplace, please visit the Google Play help center for troubleshooting tips.

The more you use an app, the more space the app takes up on your phone. So if you use Instagram more than other apps, it's likely it will take up more space on your phone than apps you don't use as often. However, your phone automatically resets the storage space an app uses every week, so you don't need to worry about storage for any app becoming gradually larger over time.

If you want to manually decrease the amount of space Instagram takes up, you can delete and reinstall the app (your photos and profile data will be saved).

On iOS, you can find out how much space Instagram takes up on your device by opening the Settings app and tapping General > Usage and finding Instagram in the Storage section. The Android app may take up more internal memory than other apps on your device because we cache photos, which makes the Instagram experience faster for you and conserves bandwidth (which means you don't have to re-download photos over your carrier's network). Note that as of v1.0.3, you can install the app on your device's SD card.

On Android, you can find out how much space Instagram takes up on your device by following these steps:

1. Exit Instagram
2. Open the Settings application on your device > Applications > Manage applications > Instagram
3. Total Storage is listed on the Instagram screen.

If you choose Clear data, your download cache will be cleared. Clear cache will reset memory for the app.

If you're trying to install or update Instagram and the app is stuck on "Installing," first try turning your device off and back on by following these instructions:

• Hold the button at the top of the phone until the red slider appears
• Slide the red power button off
• Wait about 30 seconds, then hold the top button again to turn your phone back on

After you restart your device, please retry installing the app. Some users have reported that syncing their device with iTunes and reinstalling from iTunes helps with the installation process.

If these troubleshooting steps do not help, please contact Apple support.

You can run Instagram on any camera phone with Android 2.2 or above with support for OpenGL ES 2, as well as tablets with support for OpenGL ES 2.

Additional information:

• Phones without OpenGL ES 2, such as the first generation HTC Wildfire, do not have the technology required to power Instagram's filters, and therefore cannot be supported.
• Phones running Android older than 2.2 do not have the technology required to power Instagram's filters.
• There is a known issue with some Samsung Galaxy Y devices that causes images to appear black on the filters screen and when uploaded. We are currently investigating this issue.

If you believe your device should be compatible with Instagram, please complete this form for our engineering team to review. Instagram v2.0 and later versions are supported on iOS 4.2.1 and above. If you are not running this version of iOS or later on one of the devices listed below, you will continue to see the old version of Instagram (which does not include the Lux feature or new filters such as Sierra).

You can find your iOS version by opening the Settings app on your device, then tapping General > About.

• iPhone 5
