Google Nexus 4 Camera Always Hangs
Scenario: With 8-megapixel camera, users often use the smartphone in taking pictures. However, it seems like the stock camera app in some units has the tendency to lag and freeze. Many users reported that they’ve encountered having to reboot their device because it froze when they were taking pictures. Others reported that there are noticeable lagging and freezing every time they use the camera.
Resolution: One XDA developer who has built a custom ROM for the Nexus 4 based on Android 4.2.2 and whom I was able to talk with about this problem said there’s no problem with the stock camera at all. There are also no problems with the hardware. However, he said, there seems to be some minor issues with the gallery app.
Both the camera app and the gallery work together in an Android environment. When the sensor snaps a shot, the camera app will do its job and relay the picture to the gallery app for storing and viewing later. This is where the problem comes from, he said. That’s why lags happen after the photo was taken. Fortunately, this is only a minor issue and it happens after several weeks or months of using the phone to take pictures. If this problems happens to you, you can do the following:
Clear Gallery App Data
- Go to Settings, then scroll to and tap Apps.
- Find the Gallery app and tap on it.
- Tap Force Stop.
- Tap Clear Cache.
- Tap Clear Data.
- Launch Gallery again.
You can now try to use your camera again to see if lags were gone. If they persist, try rebooting your phone.
