    Hi, I am using a Samsung Note 9 since 1.5 years. Have been using different Samsung phones for past 5 years and a same google account is linked to them. This afternoon all of a sudden my phone's 4 digit pin changed automatically. I haven't forgotten it for sure as I am using the same pin for last 3 phones and I am 100% sure about the pin. Luckily I had enabled the fingerprint so I can still log in to my phone. There was no OS update either during this time so I am really worried what could be the reason. For the time being I have changed my Hotmail and Gmail passwords and blocked my all online transactions. Now I am thinking if taking a back up and then to hard reset the phone but I am really interested to know what it could be. If it is a hacking attempt/malware then master reset will erase it or not?

    Welcome to Android Central! It's more likely to be a phone glitch, not a hack. Can you use Find My Mobile to remotely change your PIN? https://findmymobile.samsung.com/.

    Hi, thanks for your reply. first of all sorry its Note 8 not Note 9. No I cant remotely change the pin as when I try to unlock the phone using https://findmymobile.samsung.com/ it tries to reach out the phone but unable to unlock stating "something went wrong". the phone location is showing correctly though

    You may want to back up all of your important data while you can, then do a factory reset and set the phone back up again.

    Thanks Diddy, I will do that now. Just wondering if there is any way to find out if there was a malware or system glitch. And just in case if it was a malware, will I be removed by a factory reset? or shall I take any additional step before installing back all the apps etc.

    I doubt it's malware, but if it were, the ability to get rid of it with a factory reset may depend on if it were installed to the system root or not. If it was, then a factory reset probably wouldn't help -- you'd have to reinstall the firmware.

    Thanks a lot for your kind help. So before factory reset I simply restarted the phone and bingo, the same pin worked. I am a bit extra cautious so still I am doing the hard reset. One more thing I have noticed from last few months is that whenever I restart my phone it takes too much time, then it hangs in the middle and then restart again. I hope it has nothing to do with it.
