Download and install the app from our official website.
After installation completed, open the app and grant all the required permissions (some permissions are automatically granted in lower android versions). You can go to homepage after all the requirements are satisfied.
On the homepage, there are two buttons. Setup contact and Get information.
Setup contact: This is where you will save and delete your trusted contacts. The only contacts saved here can help you locate your device.
You will be prompted to authenticate with whatever you've set to secure your device. Enter your credientials or biometric (if supported) and proceed.
You must enter the contact's name and phone number and click on SAVE button to save it. You can only save maximum 5 contacts.
You can also choose the contacts directly from your contacts list. For this, the app must have "Read contacts" permission. If you have allowed when opening app for first time then you are good to go. Otherwise you can enable it manually by going to App info > Permissions > Read Contacts > Allow
You can delete the contacts by long pressing and click on DELETE button. The contacts will be deleted without confirmation. You can also delete multiple contacts by simply long pressing each contacts you want to delete and click on DELETE button.
Get information: This is where the magic happens. You will control the other devive (may be lost device) from here. As you can see there are three buttons whose job is written in itself.
You must enter the phone number of the device to which you want to perform one of the three actions.
RING: When you click on RING button after entering the phone number, you will see a prompt with some information. When you click on SEND button from the dialog, a message with command "fmdoff ring" will be sent to the number. "fmdoff" means Find My Device -Offline and ring means obviously to ring. The initial word "fmdoff" is used to identify our message from rest of the message. The message with this prefix will only be checked and other messages are ignored. For this command to work, the other device must have this app installed with all the required permissions GRANTED. This command will play a device's default ringtone on the other device at maximum volume even if phone is in Silent or DND (Do not Distrub) mode. The ring on the other phone can be stopped by clicking on this app's notification or directly opening the app. ONLY USE THIS COMMAND IF YOU ARE CLOSE TO OTHER DEVICE.
LOCK: When you click on LOCK button after entering the phone number, a message with "fmdoff lock" will be sent to the number. Activation of Device admin was asked only for this command to work. It basically locks the device (if any screen lock methods like PIN, password or pattern was used) if the device is unlocked.
INFO: When you click on INFO button after entering the phone number, a message with "fmdoff info" will be sent to the number. After this message is recognized by app on the other device, the app checks whether the number is available in "Trusted contacts" (this is done for both RING and LOCK commands too). Message is ignored if none of the trusted contacts matched the senders number. If number is matched, the app on the other device will collect the following information:
Device's current location with HIGH ACCURACY
Battery percentage
Whether device is connected to any network or not
Device model name
The exact time at which the information was collected
After the information is collected, the url will be created with the information and sent back to the sender.
The sender can then view the information in app itself if app is open and in "Get information" page. If not, you can go to massage box and click on the link which has "fmdoff"space"link" pattern.
REMEMBER: The other device should have atleast enough balance to send back the information.
Message log: This is where all the activities you performed is displayed.
If you lost your device, first get the device with number that you have set in your trusted contacts. Only these devices can help you to locate your device. After you got the device you can open the Find My Device -Offline app from that phone. Then click on "Get information" button to navigate to the page where you can send the commands. If you believe your phone is nearby, you can just ring the phone by clicking on RING and then SEND button if phone is in Silent or DND mode. Otherwise there is no need to spend, instead try to call your phone. You may also consider Locking your phone if you believe it is unlocked somehow. And the process of Locking is same as ring. To get some more device information like location, battery level, you can request information by clicking on INFO button. At this point, you may or may not receive your device information. Below are the situations for both.
the lost device is switched OFF. As modern smartphones allow to Switch off only when unlocked, this might not be the problem until the device is in the hands of some tech nerd or battery drains out.
the account balance in the lost device is not enough to send back the information. In this situation you can transfer some amount to the lost device's number.
the lost device is out of carrier's network reach.
all the required permissions are not granted to the app in lost device.
the sender (who is trying to request information) is not saved in "Trusted contacts" list.
the lost device is ON.
the account balance of lost device is enough to send back the information.
the lost device is in carrier's network reach.
all the required permissions are granted to the app in lost device.
the sender (who is trying to request information) is saved in "Trusted contacts" list.
You can perform all the above actions even if the sender's device does not have this app installed. Here's how:
Open messagebox and send the following commands to perform the resepctive actions.
type fmdoff ring and send to ring device
type fmdoff lock and send to lock device
type fmdoff info and send to request information
After requesting information you will receive message in app's "Message log" if app is open and in Get information section, otherwise you can see it in messagebox. If the received message begin with "fmdoff" prefix followed by link that looks like https://fmdoffweb.pages.dev/info/?... (be careful on link), then you can click on that link to see the information. If the link cannot be clicked, copy the link and paste it in browser.
There you will see the device location with some additional information.
Click on "Me" button and allow the location permissions to see your location. After your location is successfully received by browser, you will see the path to your lost device with distance.
Click on "Device" button to locate device on the map.
Click on "Path" button to reveal full path on the map.
You can also check the "Follow" to follow respective items on the map by simply clicking one of the buttons.
