I’m one of the many people who experienced a problem with my Android device missing from Device Manager. I had two devices listed, but for some reason, one of them was stubborn. Here is the path I took to troubleshoot this issue.
After reading various reports of this issue, each of these steps were claimed by at least one person to have fixed this problem.
1. Check Device Manager Setting
The setting can be enabled or disabled under “Settings” > “Lock screen and security” > “Other security settings” > “Phone administrators” > “Android Device Manager“.
2. Battery and SIM Pull
I powered off my device and pulled the battery and pulled the SIM card out. I then plopped the battery back into the device and turned it on without a SIM card. Let it sit for two minutes without a SIM card. I then powered off the device and inserted the SIM card again.
3. Reset Google Play Settings
- Go under “Settings” > “Applications” > “Application manager” > “All” > “Google Play Store“.
- Tap the “Force stop” button.
- Select “Storage” > “Clear data“.
- Back out back to the “Application info” screen, then tap “More” at the upper-right corner.
- Select “Uninstall updates“.
4. Remove Google Account
- Open “Settings” > “Accounts” > “Google” > “More” > “Remove account“.
If you don’t have the option to remove your Google account from your Android device, it may not let you without having a second account added to the phone first. Add a “dummy” account to your Android, then remove and re-add your main account.
Option 4 was the process that worked for me. I’m not 100% sure though. Perhaps option 3 just took some time to work? Anyway, I am now free of my Android device missing from Device Manager problem. It works and I hope these steps work for you too.
If you have a different solution that worked for you, please share it in the Comments section.
