Well, I don't seem to have an answer why this was happening, but I got some advice about how to finally fix it.
From Ryan Lestage on Google+:
Clear data for the following apps:
Google Services Framework
Restart your phone.
Fire up the Play Store app.
Wait for the device to show again on the web Play Store. It will appear ...
Although difficult to generalize, in a pretty good number of cases, using a lock screen PIN/password is not going to be sufficient to prevent someone from wiping your phone and/or flashing it with a new ROM. It may be an effective enough deterrent to prevent them from accessing your personal data, but there are a few considerations that go along with that, ...
In the end I was able to solve the problem by clicking the "Emergency Call" button.
That enforced the keyboard to come up and after closing the Emergency Call screen there was a window to enter Google Device Manager password.
Clearing cache of apps is one of the to-do things if your app is laggy, unresponsive or misbehaving.
It's absolutely safe, unlike clearing data of apps which makes you lose all the app data, accounts, settings etc.
For 1,4 a definite yes. For 2, 3 it is no. Re: safety being app dependent, it is possible that the cache is used for storing data and in the ...
The answer is almost certainly yes.
Someone could probably get past it in one way or another. (They could probably just use odin on a samsung device for example. Though I have never done something like that myself.) If you have sensitive data on there then a remote wipe might be the best thing.
Did you report it stolen with your carrier?
They could ...
The Android Device Manager app doesn't control whether your device is tracked by ADM. It simply allows you to see and manage your other Android devices.
You need to go to the Google Settings app, choose "Android Device Manager", and un-check "Remotely locate this device".
When locking a device using Android Device Manager it replaces the previous "Screen lock" with a password. Once you have entered the password you can follow these steps to remove/replace the screen lock:
Go to Settings > Security > Screen lock
Enter the password you entered via Android Device Manager
Choose your new screen lock method (Pattern, Slide, PIN ...
The Android Device Manager application has access to many device permissions. Some of those allow it enable GPS capabilities in order to find out the device's current location. Once you enable it on your phone, you can log into ADM's web site, and provided your device currently has Internet connectivity, you can send a request to your phone to retrieve this ...
I tested this on a Nexus 5 (v5.0.1) running UK English. I locked the device with Device Manager then, without unlocking it, I used Device Manager to lock it a second time. I then used the second password to unlock the device. So, you should be able to change the lock password using Device Manager - it seems that only the last lock password is required to ...
If you have the Android Device manager app installed then this can also make the force stop/uninstall updates buttons be disabled.
If you uninstall the Android Device manager app and disable "Android Device Manager" as a device administrator then those options should be enabled.
Actually, it is very straightforward.
Remove the work Google account from your phone and then add it to Gmail app as an IMAP account instead of a fully functional Google account.
If it is added as an IMAP account, it doesn't get linked to ADM or any other Google app, for that matter.
From How to add Gmail account without adding Google account on Android - ...
I spent three hours on the phone with Google yesterday for the same issue. They said there is no way to reset the password. They said I have to delete and add the user back, losing all data, pictures, game progress, etc. There is also no way to prevent a child from setting a password. Clearly the people at Google have not thought this through. It is ...
Right. This is possible, which is great. Log into the Android device manage for a second time, before connecting the lost device: set a password, click on the "wipe device" option, but then press cancel instead of choosing to wipe it. the earlier request is then cancelled and your recovered tablet can safely connect to the net. The new password will appear, ...
It's not hardware or even firmware.
It's part-and-parcel of Google Play Services, which is what Google is using to try to free Android users from the tyranny of OEMs and mobile carriers which do not provide timely OS updates (if at all).
It's not quite an app, although it installs like one. It's a framework upon which other apps and services can be built.
No, as the device will require the new password before it will successfully log in to the Play Store app to download any apps.
Again, No as it will not send any data to Google because you've changed your password.
I'm not aware of any way to find out this information. Unfortunately by changing your password and ending sessions there is no way to communicate ...
To disable application notifications for versions prior to 5.1:
In the device section of the settings menu, choose "apps" from the list.
Choose "all" from the menu to show a list of all installed applications.
Locate the application, in your case Android Device Manager, it may be labelled "Device Manager".
Highlight the application, then ...
How could a locked phone with a recent Android OS be unlocked, taken out of airplane mode, and home screen accessed?
It wasn't. The person simply pulled out the sim card from your device, added into some other device and installed WhatsApp on it. WhatsApp doesn't have any login authentication, it will simply let anyone use it as long as they have access to ...
Why not for sake of it, activate 2-step authentication on your Google account?
And just use the random generated password instead, be sure you have enabled Google to SMS you for any login attempts on your Google account, and keep your real password hidden. That is what I use here, where-ever I log in, I get an SMS direct to me, asking to enter the ...
It is now the morning after the evening I wrote this question. My Lock and Erase settings are now automagically present in Android Device Manager.
I have not changed any settings or powered off the phone, it was just 'sleeping' last night.
So it looks like the Google servers needed some time to enable the settings.
Remove "locked by android device manager" without factory reset.
Here are the steps:
Ask the owner in order to get the passcode or password
(Once you have the passcode or password) Go to settings > Lock screen
Enter passcode or password
Select none or whatever you choose to use
In order to see it, swipe down from the area at the top (Notification panel)
The title is a bit confused. @bmdixon's answer works for the situation that you want to delete the password in the case you knew the password. However, in most of the cases we want to remove the password we just forgotten. My answer is based on this.
For Android 4.4 and below, you can sign in Google account to reset the password.
For Android 5.0 and above, ...
It would depend on the phone, but as firesoul453 said in his answer, almost certainly yes.
Locking the phone is intended to protect the data - In other words: the thief cannot get your data off of the phone. Due to the nature of the android system though, it's usually very easy to wipe out the data on the phone. Usually this can be done via recovery, or ...
Ok, just posting an answer in case someone with the same problem finds this.
I took a change and hit "clear credentials." Afterwards I was able to select NONE for screen-lock again. So far haven't noticed and side-effects to clearing credentials.
In your phone, go to the settings, then go to lock screen and security, tap on other security settings, in there you'll find Device administrators, tap on it, then you will find the option "Find My Device" you can turn it off or on.
This settings path may be OEM-specific; other devices may have slightly altered terminology, though Device Administrators is ...
It might be a bit late but I had a similar issue and found a genius idea that might help others.
If you have an OTG cable, you can plug in a mouse and use that to unlock the phone, then cancel / change it as you normally would.
Hope this helps!
in your phone, go to recovery, wipe/ clear cache then reboot the phone. wait for 5 minutes, then through this link to lock the pin with new pin https://www.google.co.in/android/devicemanager
use the newly entered pin in the above link to unlock ur device
i forgot to tell you how to clear cache.Press and hold the Volume Down button, then press and hold the ...
As you can have multiple devices associated with the same account (even if they're all of the same brand and model) and still target them separately, there must be an identifier. Logical conclusion is that identifier being the GSF1 android_id. When you register your "replacement", a new android_id will be created for your ...
