Call of Duty: Mobile’s 13th season, called Winter War, kicked off on 21st December and will run through the week. Many players are reporting black screen errors after the Season 13 update to the game. Here’s how you can fix the black screen error on both Android and iOS systems.
If players experience app crashes or freezes, or the app won't open when you try to launch it, here are some of the steps you can take to fix the issue. Make sure you check if the fix has worked before attempting the next fix to see if it has solved your black screen issue:
If players are seeing a black screen after the Activision logo, it can mean that the data file (OBB file) is missing, incomplete or corrupted. The OBB file consists of all the data from the game like maps, videos, graphics, etc. The game won’t work right without it. In order to avoid the black screen issue in the Call of Duty: Mobile, players will need to download the OBB file and transfer it to the following location:
Launch a file manager and create a folder called 'com.activision.callofduty.shooter under Android/obb'. Paste the Call of duty OBB file in the newly created folder. Alternatively, players can also uninstall the entire game and install a fresh copy of the game from TapTap. This should most likely solve your black screen problem.
Downloading the APK file will also automatically update the OBB fIles. This should fix your black screen issues.
