If you receive a "failed" error in your feed when trying to upload a photo, please test to find out if uploads fail on both WiFi and 3G/EDGE.

Note that you may not be able to upload photos in areas with weak signal. Also, some mobile carriers rate limit users after they use a certain amount of data in a month, which oftentimes results in failed photo uploads to Instagram. It's common for users to have more difficulty uploading photos towards the end of the month as a result of rate limiting, or data throttling.

If you continue to receive these errors even after tapping "retry," please follow these troubleshooting steps or contact your service provider directly.

If Instagram is crashing when you are trying to upload a photo, it is often due to memory issues on your device. If you have applications running in the background, they could also be using up a lot of your phone's memory and causing Instagram to crash.

Please try turning off your device and turning it on again. Doing that resets the device's memory.

If turning off your device does not fix the crash issue, please email us and provide as much detail as possible, including your device, OS version, Instagram version and when the crashes occur most often.

If you're using Instagram and you get stuck on processing, please try force quitting the app.
On iOS devices, you can force quit by following these steps:

1. Exit the app by pressing the Home button on your phone. (The Home button is the physical button at the bottom of your phone with the white square on it.)
2. Double click the Home button and a tray will pop up.
3. Find the Instagram icon. Press and hold the icon for 5 seconds until the icon starts to shake.
4. Press the red minus button that pops up on our icon. This will force quit the app, and you should be able to log in normally after that.

On Android devices, you can force quit by following these steps:

1. Exit Instagram
2. Open the Settings application on your device
3. Tap Applications > Manage applications > Instagram > Force Stop

Users who upgrade to iOS 6 and choose to restrict access to the Camera Roll will receive the following message when attempting to import a photo into Instagram: "This app does not have access to your photos or videos. You can enable access in Privacy settings."

To adjust your privacy settings, follow these steps:

1. Exit Instagram
2. Open the "Settings" app
3. Select "Privacy"
4. Select "Photos"
5. Toggle the ON/OFF switch next to Instagram to the "On" position

We are fixing an issue where the Android app crashes and returns users to the Instagram Feed screen (without uploading the photo) or crashes and returns to the device's home screen when trying to apply a filter.

Some users have fixed this issue by increasing the camera resolution setting from their device's camera settings, or by updating to the newest operating system available for their device.

Please note that some devices seeing this crash do not support OpenGL ES 2, which is the technology required to power Instagram's filters. Devices that do not support OpenGL ES 2 will not be able to run Instagram properly. Find more information on whether your device is supported.

The Lux feature is not supported on Samsung Galaxy Y, as this device does not have the processing power to support this feature. As of v1.0.5, the Samsung Galaxy Ace does not include this feature, but we hope to provide support for it soon.

If you are having issues with Lux on a different device, please file a report with details.

Android version 1.0.3 included Instagram support for tablets.

Some Android tablet users may experience rendering glitches when applying the Lux feature.

We are investigating the cause of this error.

Some users have found that location is not stored with their photos when importing them into Instagram after updating to Apple iOS 5.1. To fix this issue, close Instagram and open the Settings app. Next, tap Location Services and turn location ON for the Camera app.

This issue occurs when:

1. You select a photo from your camera roll that was taken after you updated your phone to iOS 5.1.
2. You tap to add geolocation, then tap again to select a specific location where your photo was taken.
3. When you go to select the exact location where your photo was taken, you are presented with location options that are around you now, not when you took the photo.

Please file a report if you continue to have issues.

We are aware of an issue where the location map popup is partially obscured. This may be because there is no Foursquare location associated with the image's geotag.

If no locations are appearing when you upload a photo, you'll need to enable location for Instagram. To do this:

1. Exit Instagram
2. Open the Settings app
3. Tap Location and security > Use GPS satellites or Use wireless networks

This issue has been resolved as of Instagram 3.4.0. Please download the latest version of the application from the App Store in order to select photos from any of your device's photo albums.

We are aware of an issue on some devices, including the HTC Sensation, where applying tilt shift results in a pixelated photo, or an extremely blurry photo. In some cases, applying tilt shift causes the app to crash. We are currently investigating this issue and hope to have a fix out soon.

We are aware of an issue with Samsung Galaxy Y (GT-S5360) and Samsung Galaxy Ace (GT-S5830/M) where images will appear distorted or scrambled.
