How factory reset works in adroid phones?? - Android Q&A, Help & Troubleshooting

Hii all,
As most of the user are using android smartphones and now i am using moto g5 plus so i wanto know more about factory reset protection?
How it works?

Factory Reset Protection is a security method that was designed to make sure someone can't just wipe and factory reset your phone if you've lost it or it was stolen. It's a good thing — it makes a stolen phone harder to use, which makes it less appealing to thieves, and anything that can protect our data on a phone we've lost is welcome. It can become a problem if you sell, trade, or even give away a phone without factory resetting it, though. How it works explains why.
You have to be signed in with the "owner" account of the phone (the one you used to set it up) in order to factory reset it. That means if you give me your phone I can't reset it without you being signed in There are random workarounds on the Internet, but they tend to get patched almost as soon as they are discovered. You'll pretty much need to know the login details for the last account to use the phone before you can reset it and create a new owner account.
Disabling FRP (Factory Reset Protection) is simple. On most phones, it will be automatically done whenever you choose to reset the data through the phone's settings. If your phone has an extra layer of reset protection from the company who built it or has a "find my phone" app from the company who built it, you'll want to disable that manually first. :angel:

[Q] Android data security best practices?

The full phone encryption as currently implemented on Android is inconvenient because you have to enter 6+ chars every time you want to unlock your phone.
Since most of the time you want to do something unimportant, it quite kills the usability.
Knox seems to have nice approach to that by splitting the phone into personal and business part, only the later being protected.
However it's inaccessible for non-corporate customers, and still unclear how exactly it works.
So are there any other solution that allow you to protect part of your phone, like encrypt choosen folders only and password/pattern protect specific apps only, while still leave the most of the functionallity of your phone conviniently accessible?
Well, you can always go for a combo... PIN + encryption of files + password protected apps... and cerberus for anti theft (you can always remote wipe and try to recover the mobile after). Of course most security measures are "wiped" soon as the phone is wiped to install a new firmware, but while it isn't... there's a short window to recover your phone.
Seems like there isn't much security apps to more serious issues either...
The biggest issue is that PIN + encryption kills the usability since you have to enter the PIN (6+ chars) every time you want to glance at the phone.

Mobile Phone Stolen - Questions

Dear people,
my huawei mate 10 pro got stolen yesterday. Unfortunately I forgot my password for my google account, so I had to reset the password on my computer. There I could see that the mobile was last online on that day, when I was out. But since I had to reset my password with my second sim card, I wonder if I'm still able to locate it with my google account, since the passwords don't match anymore?
I had my mobile locked with a not so easy pin. I had installed Android 9 on it. How high are the chances the thief will unlock it, to get into my data? I activated remote erase, but as I said, the phone was not online anymore.
I also wonder about google's FRP. So when I have a google account on that phone, the thief won't be able to erase the data? But also, when he unlocks the pin and wants to erase the data, he won't be able to and likely sell it with the data on it?
Lot of questions. Sorry. Would be nice to hear from you!

anyone?
Hi
Your device data probably got erased by a factory reset. A thief would not waste time trying to unlock the phone if it's locked. However, if the phone had enabled usb debugging before you lost the phone, He could remove the password though a pc and have access to your data. It depends on how far you got with the phone. ( if you tampered with it or not).
If you bought a new phone and you are willing to modify it in order to ensure security, you could install a custom recovery such as TWRP and password lock it to prevent factory reset. (That's what i do at least).

How wipe phone for sale so new person does not need my pin?

I have wiped and reloaded my phone a couple times, and each time it asked for my pin when I was setting it up. Said something to the effect of "...phone has been used, Enter your pin number".
Is there a way to wipe it so that doesn't happen?

Very surprised. What PIN number are you referring to? SIM pin number is obviously asked for each time a PIN protected SIM is inserted. As far as device pin / lock pattern... are concerned, they are erased by a factory reset.
The only important thing is to delete all Google accounts form the device PRIOR to the factory reset, otherwise the last used Google account is required during the next setup.
On Huawei devices might also need to delete Huawei account from device before factory reset.
Thanks.
May be the Sim, not sure. And I had not deleted the accounts before reset All the years I've been using smart phones never heard to do that.
Thanks again. Next week I'll be doing the reset, and I'll report back confirmation of how it goes
It's called Factory Reset Protection (FRP). You can google it. Basically, if a Google account is present on a device at the moment of the factory reset then the credentials of this account will be required during the set up wizard that follows the factory reset. It's a theft protection but in your case (sale) this is not something you want.

Galaxy A50 Hard Reset Blocked

Hi, it would be good if someone can give me some advice on resetting a phone that I have, which appears to have the reset function disabled.
I have had my business phone upgraded and am left with the old device which is a Galaxy A50 which has not been asked to be returned. This phon e is newer than my personal phone and was wondering if I could use it. I have tried putting my sim in it and made a call which works fine (they are both the same phone network provider). Trouble is I can't put any new Apps on it and it's locked to the corporate settings.
I tried to carry out a hard reset but that option appears to be blocked. When the phone reboots it does not go into the android boot menu but instead goes straight to full boot with the screen lock. I plainly know the screen lock as it was my old phone.
I have also done some reading and it seems that if I was to be able to reset the phone I would need the email account to get back into it. The phone has 3 email accounts, none of which I actually need:-
- my work email account (exchange)
- my work email account (work account)
- an android email account (numerous numbers @ANDROID-for-work.gserviceaccount.com)
Before I do anything that may brick the device, I was wondering if anyone can offer any advice on how to make use of this. Seems a shame to just bin it, and I know my business won't do anything with it, it'll just get dumped. I don't need anything on the device, just want to do a total wipe and start from fresh.
Thank's in advance if anyone can help.

Fingerprint works but pattern not recognized anymore

Hello!
I'm facing a very weird issue with my HTC U11 Life.
I've been using it for years with the same pattern and fingerprint, and out of the blue, my pattern appears as wrong while I haven't changed it.
It happened for the first time after restarting my phone (I switch it off pretty often though).
The fingerprint is recognised, but the pattern isn't.
I have no other option on the screen than the emergency call (no "forgot pattern"/enter password/pin/connect to my Google account), and the "find my phone" doesn't show anything ("Can't reach device"), even if it's connected to my home regular wifi.
Not sure it's relevant, but I tried to deactivate the pattern a month ago, as I'm using that phone only at home. But it sounds like it didn't go through.
After browsing forums for hours, I tried a few steps, all unsuccessful.
Using the ADB tools, when I enter the bootloader, I run “./fastboot reboot bootloader”, after which I see the device show up in “./fastboot devices”. Then I try to run “./fastboot boot twrp.img” for the HTC U11 Life, at which point I see a “Device corrupt, cannot be trusted” message. So I seemingly can't progress without flashing my phone, which I don't want to do.
I should probably also mention that I have another phone (Google Pixel 6), and I tried to put my home as a "Trusted place" for my Google account, but it unfortunately didn't change anything.
I saw the hard reset option but I can't afford losing any data on that phone, and I believe there is a solution given the fact that I can provide the right fingerprint and any password, if they're requested.
I hope your fabulous community can be of any help.
Thank you very much!
Take it to a data recovery specialist if you really need the data. They might be able to recover it.
Either a hardware failure or possibly malware, or a Single Event Upset.
Always redundantly backup critical data. Avoid encryption if possible. Use an SD card as the data drive if you have that option.
Hey Blackhawk!
Thanks a lot for this super quick answer, I really appreciate it
I should admit I have a hard time believing a malware attack, given that I was barely using Internet on this phone. So that indeed must be a hardware failure or a Single Event Upset. Go figure!
That's a pity that there is no solution to that, especially that my fingerprint works, which is super frustrating. Anyway, too bad, I guess I'll factory reset as it's my only option.
Have a great weekend!
seems theres no way to fix this

There is. A factory reset. The data partition was somehow corrupted. If it reoccures then either the firmware has been corrupted or there's a hardware failure.
Anytime you set a password for device access, you are the one most likely to get locked out. It may be through no fault of your own however had no lock had been set you have a higher probability of retaining access.
NEVER set passwords for backup drives. Always keep backup drives isolated from everything unless in use.
