      With Android versions from (reportedly) 7 onward

      If you use Play store and sign in, NEVER FORGET, if your phone crashes or some app soft bricks it,

      IF YOU ARE STILL LOGGED IN TO PLAY STORE AND DO A FACTORY RESET YOUR PHONE GOOGLE WILL TOTALLY BRICK IT.

      Maybe in some few cases a Factory approved shop will have the approved software to reflash the OS,
      on your model after you prove you own the phone.
      You will probably be quoted for a new board, or told to send the phone back to OEM in India or China.

      If you will buy a second hand Android phone ensure the seller does a factory reset in front of you

      Before you sign a contract or pay. If you do not you might purchase a nice piece of electronic junk,
      the phone will look normal until it has to be reset, if the previous owner did not log out of play
      store the reset will brick it. I love the way google protects me from damage.

        Just had to buy a new phone, too, a couple weeks ago. Didn’t buy the insurance. So… thanks for the warning.

        What do you think about this: If I had to reset it because of a crash, would it work if I entered into my google account on the computer, then logged out of google services FIRST (before resetting), that way? (I’ve been urged to do that by google in the past, for seldom-used tablets/old phones used as toys by grandkids.)

          Hallo christophe, I am not sure about using the computer to go in to google services then logout,
          I think that would probably not work as the play store, google find my phone is likely to be coupled by
          Android system Id which is regenerated at every reset or perhaps IMEI numbers.
          Googles idea is to make stolen phones useless, users phones bricked is seeming of no interest to them.
          they make more money with every phone sold.

          Maybe some further information will be on XDA developers site.

            Moddit, I assume this is common known as “Google lock” in the second-hand Android phone/tablet market. It is supposed to work like this:

            A. If a phone (or tablet, for that matter) was factory reset BEFORE the previous owner remove (a.k.a. sign out) their Google account from the phone’s setting menu.

            B. Then in its next reboot, it will ask the user to input the Google account email and password which was last (or perhaps once?) used on that phone.

            C.1 If this step passes, the phone should boot normally so that the new user would have a chance to sign in (thus binding) their new google account with this phone.

            C.2 Otherwise, the phone would stay in the Google account challenge step during boot (thus known as “Google lock”), though technically speaking, it is not bricked. You can always proceed to C.1 if you know that proper account info.

            This mechanism is designed to target the scenario C.2 which typically happens when a phone is lost or being stolen. There is no known common way to bypass it, at least not as a knowledge to the consumers. Stay away from these kind of phones if you are in the market for a used phone.

            So, Moddit, you are supposed to be presented a UI for you to sign in. Is it not the case?

            If you will buy a second hand Android phone ensure the seller does a factory reset in front of you
            Before you sign a contract or pay. If you do not you might purchase a nice piece of electronic junk,
            the phone will look normal until it has to be reset, if the previous owner did not log out of play
            store the reset will brick it.

            In second hand market, not every seller is tech-savvy to do a factory reset, but every legit seller would at least provide the phone in the condition that the screen lock is removed. So as the new owner you can:

            X1. sign-out ALL existing Google account, if any (you do not need to know its password for sign-out)
            X2. optionally perform a factory reset,
            X3. and then sign in with your Google account.

            It is supposed to work. But because your Google account’s binding to this device is NOT establish until step X3, so, if you have concern of you might lose access to this device after step X2, you can use the alternative like this:

            Y1. Sign in with your google account FIRST. Once your Google Account is successfully login on this device, you should no longer be hindered by the Google Lock issue in future.
            Y2. Remove the ex-owner’s google account (if it is still there)
            Y3. (Optionally) factory reset the device.

            The Y solution has an overlap of ownership, so you won’t expose yourself to the risk of Google Lock.

            What do you think about this: If I had to reset it because of a crash, would it work if I entered into my google account on the computer, then logged out of google services FIRST (before resetting), that way?

            Whether you are able to login with the same google account on the computer is irrelevant. Google is not locking your account, it is locking your phone.

              Hi all, in the case concerned the phone went in to boot loop after an app installed from
              from play store by the user crashed and made the phone non responsive/locked up.

              Now after reset the device is presumably assumed to be different hardware. My assumption is due
              unique android id created on android init.

              The fact that google can lock other peoples, in this case two day old phone is not widely known,
              at least to our knowledge and can go very wrong. which is why the post was made.

              This also seems to happen to phones from China which have a shop ROM. Chinese market phones generaly
              have only chinese and english as standard — and no play store which I consider a big advantage.

              Shop ROM have added other languages and Play store.

              If you are removing bloat from a phone LOG OUT OF PLAY STORE FIRST. Be careful removing some applications
              can cause boot loop and otherwise trigger google lock.

              OT. Play store is the worst tracker I have found on any phone, soft sell is device theft protection,
              it does not stop theft. It does generate an extremely high definition user profile.

              And can hurt honest buyers.
