Recently Used Apps crashing in portrait mode

Question

When I try to switch to the "Recently Used Apps" screen (by holding the home button), the process com.android.systemui crashes.



However, in Landscape mode it works as usual (and rotating the device makes it crash again).



Device: Samsung Galaxy S4 Mini
Version: 4.4.2
ROM: Stock



EDIT: The system was not modified in any way (e.g. no root access).



Where can I find logs/files that provide me with additional info i.o. to trace the problem? Or what can I do to make it stop crashing (preferably not reseting)?



EDIT: Unfortunately, the issue mysteriously disappeared today and I cannot reproduce it any more.

Answer

To check logs there are a few options, for instance:




  1. Given that you have a Samsung, try opening SysDump by going to Phone dialer -> *#9900# (no need to press Dial).
    To get the logs, you might need to root your phone. This shows methods for accessing files in data/data without rooting, and it may apply to data/log as well.


  2. Use the adb to check the output of dmesg.


  3. Use aLogcat.
    Details for checking an app adapted from here, it may require some tweaking for Recently Used Apps, if useful at all:




    1. Start your target app (e.g., "Myapp") on the device. If it crashes, repeat this step 2-3 times.

    2. Next start "aLogCat app" and wait for approximately ~1 minute.

    3. Press the "Menu" button and select "Filter".

    4. Type "Myapp" in the text field and press "OK" button.

    5. Wait for approximately ~1 minute.

    6. Press "Menu" button and select "Share".

    7. Collect the log via any sharing option you have access (e.g., email, Bluetooth).


  4. Use CatLog - Logcat Reader!. You might need root Access.
