RELATED: What Does SF Mean In Call Of Duty: Mobile
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:
Android/obb/com.activision.callofduty.shooter
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.
