Galaxy S4 Problem: GS4 Reboots When Camera App Launches

The Samsung Galaxy S4 has a tendency to reboot after several hours of usage. There were also reports indicating the phone may also reboot triggered by the launching of the stock camera app. At least, that’s what some of our readers told us. Here is one email we received describing the problem.

I got a rather unusual problem with my phone, Galaxy S4, which I bought just a couple of weeks ago. The phone worked perfectly during the first week. It was only recently that I found out the phone reboots every time (yes, every single time) I use the camera. I haven’t done anything to the phone, I never updated to a new OS version (if there were any), I never installed an app ever since except the Dropbox app. I don’t know if this problem already existed since I haven’t used the camera until recently. I haven’t done any troubleshooting steps, I just don’t use the camera of my phone to avoid the problem. But other than this, the phone works perfectly. Please help. Any suggestion would surely be appreciated.

Reboots caused by extreme temperature when the phone is on the brink of overheating seem to be normal now that many owners started reporting the same problem. The problem reported by our reader is unusual but I talked with one of the XDA Developers about it and he said it’s not a bug. It could be resolved by simple troubleshooting steps.

Clear Camera Cache / Data

Since the first concern here is the camera (and there is no evidence the problem is caused by hardware conflicts), it’s logical to go for the stock camera app before anything else. The following procedure will walk through users (both savvy and non alike) how to clear cache and data of the app.

  1. From the Home screen, tap the Menu key.
  2. Tap Settings.
  3. Choose More tab.
  4. Find Application Manager.
  5. Swipe to choose All tab.
  6. Scroll to and tap Camera.
  7. Tap Clear Cache.
  8. Tap Clear Data.
    1. Reboot phone.

After this procedure, try to launch the camera app to see if the phone would still reboot. If it won’t, that’s good news, otherwise, continue with the following procedures.

Clear Gallery Cache

Majority of camera-related problems in Galaxy S4 were caused by the stock gallery app. Many reported that the camera stops functioning during the preview of a photo. One expert I’ve talked with regarding the problem said that sometimes the gallery app freezes because there are a lot of pictures that the app needs to render both their thumbnails and actual sizes.

  1. From the Home screen, tap the Menu key.
  2. Tap Settings.
  3. Choose More tab.
  4. Find Application Manager.
  5. Swipe to choose All tab.
  6. Scroll to and tap Gallery.
  7. Tap Clear Cache.

Note that clearing the data would delete some of your settings and thumbnails, although new ones will be created once you open the app again. After doing this, try to launch the camera and see if the problem was fixed.

Clear Google Services Framework Cache and Data

If the problem still persists after this, it’s time to dig a little deeper into Android’s core.

  1. From the Settings menu, choose Applications Manager.
  2. Swipe left to choose All tab.
  3. Find Google Services Framework and tap on it.
  4. Touch both Clear Data and Clear Cache buttons.
  5. Reboot your phone.

This is the last procedure you should do. If the problem still persists after this, try to do a factory reset AFTER you’ve backed up your important data. If you still experience the problem after that, return the phone or ask for a replacement from your provider.
