Can the data in an iphone can be erased like android mobile by going to recovery mode by pressing 2/3 buttons of mobiles . If not then what happens ?
What? If you want to know about resetting an iPhone, ask in an iPhone forum?

I don't want to reset an iPhone, I''m just asking a security case. Let's imagine our android being stolen, then the thief can certainly press the power and volume key and can easily wipe data and factory reset the mobile phone by just simply going to recovery. So it'll be impossible for us to find the phone.
But I'm asking in case of an iPhone is this same case possible? Can a thief just simply wipe the data and reset the mobile by pressing some keys and without unlocking the mobile ?
Gotcha. I haven't used an iPhone in years, so don't know.
I still think it's weird to ask an iPhone reset question in an Android forum though. You would probably get your answer in a minute if you just ask in an apple forum...

Isn't the whole point of factory reset protection on android that it renders the device useless to someone who does this? Sure, it won't stop them actually resetting it, so you won't be able to track it afterwards, but the idea is that the thieves will learn that it's a waste of time.
Apple have something to prevent you just wiping a phone and making it yours, but I can't remember the details (i.e. whether it prevents the reset or, like the Google version, prevents you from using it afterwards).

I concur with @Large Hadron
On an iPhone, someone could enter the password incorrectly several times and the device would be wiped. It would not be usable, but it would be wiped. They could also connect the iPhone to a computer / mac with itunes and flash a factory image from there. Again, the device would be useless to them, but you wouldn't be able to recover your device from the thief.
Comparing an iPhone to a Pixel 1 or 2, both device could easily have the data wiped from the device. To that effect, the data is secure on both devices, which is by far the most important part. Recovering your lost / stolen device is an entirely different conversation. The benefit of an iPhone when lost / stolen is the device is a brick without the previous user's icloud email and password. Once it boots up, it asks for this before you can setup the phone. There is no way around this (without Apple's intervention). On a Pixel 1 or 2, the device could be wiped, but I believe the thief could then use the phone as their own. There is nothing that would "brick" the phone after a full data wipe.
If you are worried about your data, either phone is good (don't unlock bootloader and don't oem unlock). If you are worried about the hardware, you are responsible for that.

An Android phone works exactly the same way. If you wipe it from recovery, FRP (factory reset protection) kicks in, Once that happens, you are required to log on to the last account that the phone was used on (just like Apple). If you don't know the previous account and or password, there's no way you can use the phone.
You can factory reset from settings without triggering FRP though. Doing so removes all accounts from the phone and anybody can then use it. It's assumed since you are in settings, you've already logged on when you last booted the phone. A thief wouldn't be able to get into settings to reset it as he or she wouldn't know the password to unlock the phone.

And if you really want to perfectly protect all your encrypted files, never open the bootloader. Because there's no way to flash something in the phone if the bootloader is closed. And there's no way to Open the bootloader without wiping all your personal data in the process.
Now if you decide to open the bootloader, files are still encrypted, so it's not a big deal.
Regarding the annulment of an Android device, when it is stealed: That happens with any modern Android phone. Basically, Google bans the phone from their cloud servers. A phone without google account is like an iPhone without Apple/iCloud accounts, almost useless.
P.S.: an open bootloader in Android is like a Jailbreak in iOS, but totally OFFICIAL and supported by Google/Android. You don't lose any functionality like with Jailbreak (if that thing still exist today...).
From my point of view, Google should ask PIN before accessing Fastboot mode and Recovery mode. but this is just to prevent a bad joke from a friend or something like that. (Not when your phone is lost forever, you just want to ban that device from Google servers so can't be used again).

Are you sure about that? I believe that factory reset still triggers FRP thus the black market trade in bypassing that check on lost and stolen devices.
I googled this and from what i read, so long as i log out of all services and set my lock screen to none, I then make sure that strong encryption is enabled then do a reset and this way it secure wipes?
Is this correct or am i best doing something else?

As I know, the best way to securly wipe s10+ to sell is using Samsung data eraser software. Such software can help us wipe all personal info on your S10+ phone without recovery. Then you can sell it without data leaked. Hope this will be your help.
The main way that data is stolen from wiped phones is because people fail to actually wipe them - as long as Strong Encryption on your S10 overwrites your entire storage then your data (Probably) no longer exists on that phone. Unless they can find the encryption key, but that would (should) be wiped on factory reset.
When you delete data, it isn't actually deleted, it's memory region is just marked as free real estate for new data to be written. Once it's replaced it's gone, otherwise its recoverable. Encryption should do the trick, as the data in memory marked as open will be scrambled without the key.
If you're feeling particularly paranoid however, you can also load dummy data onto your phone for an extra layer of protection, there are several tools for doing this, some of which are on the play store, before wiping it a second time.
Good luck with the sale!
(EDIT: Nazhais suggestion popped up as I was writing, but yes, data erasing software is probably the way to go.)
Just found that my new Samsung S20 FE running Android 11 turned on FBE encryption by default and there is no way to disable it (unless factory reset + wipe all data + root). Once the device is physically damaged, there is no way to recover the data. I think it should offer some methods to non-root phone owner to backup the master key or create recovery key but google doesn't give any solution. I don't plan to root it since I use Samsung pay, rooting it will trip KNOX and disable Samsung pay permanently (Damn you!). May I know if it is possible?
You may argue that we should do backup but mobile data is not free, wifi is not available everywhere and you backup is never in real-time. You will always lose some data even you do daily backup. Comparatively I also use BitLocker on Windows (I know it is FDE that work different from FBE), I have created a recovery USB drive and store it in a safe. I wonder if similar can be done on my phone so I still get chance to do chip-off data recovery even it is physically damaged.
I have a similar question, but as far as I can tell; we're S out of L
Hi guys.
Helping a friend out here and since i've not been using a Samsung since my Note 4 era, i've kinda lost my knowledge regarding Samsung programs.
So she has forgot the PIN lock and the phone are now locked (well it still aks for the Pin lock). The last resort is to just wipe the damn phone, but as we all know, not everyone use the cloud so all the pictures are stored at the internal memory.
Any ideas if this is possible without USB debug beeing enabled?
If she can access using her Samsung or Google account maybe... not sure.
I never set passwords for device or bios access because you are the most likely to get locked out. Maybe through no fault of your own like if the password goes corrupted. It happens.
She will lose all data if she can't gain password access because the device's data is encrypted.
In the future she needs to redundantly backup critical data to at least two hdds that are physically and electronically isolated from each other and the PC. Some lessons you learn the hard way... been there, done that
Hello,
I wanted to know if there is any way to recover old data from a wiped phone (pictures, notes, Whatsapp data). My phone had a max incorrect attempt limit which would wipe the phone data if reached. I tried to use my backup that I had but Google is requiring my old PIN code for my lock screen. I can't remember the PIN, as far as Whatsapp is concerned, apparently the backup did not save to Google drive ( I think it may have been set to save locally). Any help would be appreciated!

I am trying to help where I just googled for what the answer might be and there seems to be a bunch of ways to recover deleted data (although I'm sure the level of success depends on how well it was deleted and wiped clean and overwritten multiple times with all zeroes, etc.).
Here are some of those hits which "might" help (you'll have to test them).
