I still remember the week Call of Duty Mobile arrived. It was absolutely massive. The game raced past 100 million downloads before most people could even finish their first battle royale match. It set records that still feel hard to beat. But with that huge launch came some frustrating login problems. One of the most common complaints I have seen over the years is the Call of Duty Mobile Facebook login problem. Maybe you are stuck on the authorization screen. Maybe the game signs you in but your Facebook friends list is empty. Either way, I have got you covered.
Let me be honest: this issue can show up in a few different ways. Some players cannot log in at all after tapping the Facebook button. Others log in, but the game does not show any friends. A few people even get stuck in a loop where the game sends them back to the home screen. I have tested several fixes on Android and iOS, and the solutions below usually work.
Quick Fix Table
| Problem | Likely Cause | Best First Step |
|---|---|---|
| Cannot log in with Facebook | Corrupted app cache | Clear the Facebook app cache |
| Friends list is empty | Visibility settings are wrong | Enable friends visibility in Facebook |
| Login loops or crashes | Old app version or corrupt install | Update or reinstall Call of Duty Mobile |
| One specific friend is missing | Different game version | Check if your friend uses the same version |
Fix 1: Clear the Facebook App Cache
This is the first thing I try. It sounds simple, but a corrupted cache can break the login handshake between Facebook and Call of Duty Mobile.
-
Open your device settings
-
Go to Apps or Application Manager
-
Find Facebook
-
Tap Storage
-
Clear the cache
On iPhone, you may not have a clear cache button. In that case, offload the Facebook app or delete and reinstall it. After that, open the Facebook app and sign in normally. Finally, open Call of Duty Mobile and try logging in again. This usually fixes the basic login failure.
Fix 2: Check Facebook Apps and Websites Settings
If you can log in but your friends are missing, the problem is likely inside Facebook permissions. This fix takes about two minutes.
-
Log in to your Facebook account
-
Go to Settings & Privacy
-
Open Settings
-
Navigate to Apps and Websites
-
Tap Active Apps and Websites
-
Find Call of Duty Mobile
-
Make sure the friends list option is enabled
-
Go to the visibility setting for the app
-
Change the filter to Friends
-
Save the settings
After this, restart Call of Duty Mobile. Your Facebook friends should now appear in the game. If you cannot find one particular friend, do not panic. Check whether that friend is playing the same version of Call of Duty Mobile. Different regional versions or test builds can cause this.
Fix 3: Reinstall Call of Duty Mobile
Sometimes clearing the cache is not enough. If the login loop continues, I suggest you reinstall the game. Before you do that, link your Call of Duty Mobile account to an Activision account, Apple ID, or Google account if possible. This protects your progress.
-
Back up your account with Activision, Google, or Apple
-
Delete Call of Duty Mobile
-
Restart your phone
-
Download the latest version from your official app store
-
Open the game
-
Tap the Facebook login option again
A fresh install removes damaged local data and refreshes the connection between the game and Facebook.
Extra Tips for 2026
Things have changed a bit since the early days. Facebook updated its privacy menus more than once, so the exact labels may look different on your phone. If you cannot find Apps and Websites, try searching Facebook settings for the Apps section. You can also check that Facebook itself is not down. A quick check on another device helps.
I also recommend keeping both Facebook and Call of Duty Mobile updated. Old versions may no longer support the login method properly. If you use battery saver or aggressive background restrictions, try turning them off temporarily. Some phones block Facebook background processes, which breaks the authorization step.
Final Thoughts
The Call of Duty Mobile Facebook login problem is annoying, but it is rarely permanent. Clearing the Facebook cache solves most login failures. Fixing the visibility settings brings back missing friends. A clean reinstall handles stubborn loops. The key is patience and working through the steps in order.

This discussion is informed by CNET Gaming, a tech-focused outlet that often connects game access issues with broader platform changes. When tackling a Call of Duty Mobile Facebook login problem, it helps to treat it like a cross-app authentication flow: keep both apps updated, review privacy/permissions, and troubleshoot device-level restrictions (like background activity limits) that can interrupt the authorization handshake and lead to loops, crashes, or missing social features.
