[Q] how to activate guest mode?

this was a much hyped feature of sense 4.0, to allow other people to use your phone, but not access your private data.
How do you access it?

I am also looking for an answer to this, please help

in storage you can make a password for your data on your phone but which guest mode do you mean ? this is the only thing i found

Guest Mode for All Android Phones (App)
The first time a guest mode was revealed for any android device was with the launch of LG G2 series phones. This feature was advertised so well in the media. I also bought an LG G2 at that time (not for this feature alone) as it was a great phone. I realized that a little over six months had passed and I seldom used the Guest Mode feature on the phone.
The guest mode in G2 and the one in the upcoming Android L (5.0) is something that is too apparent in nature. What I mean is that any adult who is given a phone in the guest mode will easily be able to come to know that they do not have the full access to the phone. In cultures (like India), it will be considered very rude in case I lent a phone to another user in Guest Mode. Also, what do you do when you Dad asked you for your phone, you surely cannot give him in Guest Mode (this will make him more suspicious).
This was the practical challenge when I decided to make an app for myself, the app that I have been using is similar to an app locker. However, it has been added with a screen lock as well. I chose two different types of passwords (one master and another guest). The app allows me to chose all the applications that I consider private and want to be locked (such as emails, whatsapp, other chats, picture gallery etc). When I unlock my screen using the master password, the screen gets unlocked and all protected apps get unlocked as well. When I give my phone to someone else, I just give them my guest password. The screen gets unlocked normally using the guest password, however, all the protected apps continue to be locked. This helps me easily give my phone to others.
When I gave the app to my friends, the kind of response that I received was overwhelming. So launched it for public as well. You can download the app for free from Google Play. Just search for Pluggdd on Google Play, it is the only app on Pluggdd as the developer.
Looking forward to feedback from you all developers on what is missing in the app and what more features can I add.

G3 locked out help

Edit: when the device has no internet the email used to unlock the phone is useless. The phone should keep the email and pass locally. So don't forget you pin or let anyone enter the wrong thing. I had to factory reset it however it still retained root. Strange? I wasn't able to obtain any data so far. I may try to dig deeper with a recovery program but right now I no longer need use of the device (my son has a new toy, lol).
This is my phone. Before anyone says it's not trust me it is and I can prove it via old cell bills. And that Google still has it attached to the account.
I need back into it for a few very important photos relating to an accident a few months ago.
This model was on the us cellular network. It is not an active phone. (No data). Here is my problem, not being able to connect to data or wifi networks I am locked out because my son played with the 4 digit pin. The phone now asks for my email and password. Of which I know but the phone will not accept it. Thinking that I might have updated my password since I was on the G3 last I have tried all passwords that I know I have used and still nothing. This phone is also rooted. With stock jellybean.
Any help would be appreciated.

I'm trying to avoid data loss. As I need the few images off the phone. After I get them off I really don't care what happens to the device.
march 16 per google was the last active date. From then till now it's only been a paperweight because I thought google backed up my images which isn't the case.
Does google keep passwords in a viewable manner in case I forgot one I used?
Edit: google doesn't save passes for viewing unless in your browser saved password section, however I wonder how it knows of a duplicate pass when changing the current one.

Question Hacked pixel 6

Can anyone help me carrier unlock my Verizon phone? My phone has been hacked and I hope being able to flash it will help me to get rid of whatever they have done to it. Can anyone tell me why I get this message when I reset my phone? Any help would be greatly appreciated

there is no carrier unlock for VZW models. if you can boot into recovery, sideload the OTA version that was last on your device.

What did you do that resulted in the phone being hacked? With the sectors being wiped that are shown in the images, it looks like you have provided total device access to something whilst having an unlocked bootloader or something similar. If you let us know what happened, it might help us to figure out what options you may still have.
But definitely see if you can do what @uicnren mentioned first.

Im not sure who or how they wiped anything. It happened one day after connecting to my girlfriends wifi. I got ahold of Verizon and they sent me a new phone and as soon as I started it the same thing happened to it also

How do I find what OTA version was used on my phone?

Nothing hacked here... this is an error when wiping the Secure Element (the trusted secure module).
(https://android-review.linaro.org/p...cure_element/1.0/SecureElementHalCallback.cpp line #66)
Are you initiating the wipe from the recovery? If so, that's likely the reason. If there is an account attached to the device, a wipe must first be initiated from within Android (Settings)

what symptoms were you seeing that made you think you were hacked?
Those errors are normal in Recovery Mode. I see them all the time, sometimes they don't appear, usually they do.
Did you remove your google accounts from settings, do a factory reset from the reset menu and lastly in recovery mode where you posted the screenshots from.
Your Account might be hacked but the phone is unlikely hacked. You would get a message at boot telling you that the device has been modified. With a locked bootloader its extremely unlikely (unless NSO Group is targeting you).

Did you unlock the bootloader? Have custom firmware/kernel installed?
A "hacker" wins nothing by resetting/wiping your phone. They want data, and that only works if the phone can turn on and works. This looks like a wipe/factory reset gone wrong, which spells user error or software error and less likely a "hacker" attack. Most hacks you will never notice. A hacker that makes you notice that something went wrong, is either an amateur or did it on purpose. Ergo, he wants you to know that something went wrong, which usually only happens in order to extort you. If there is no extortion, then an obvious act by a hacker is highly unlikely.
We need some more information. What firmware had you installed? What happened exactly when. Did you install any new apps recently? What did you do prior to something going wrong? All the information that could help us troubleshoot your issue.
You said your phone wiped itself a day after connecting to your girlfriends wifi, and that a replacement device that you got sent by your carrier, did the same. Did you check your Google account? Do you have two factor authentication activated? It sounds like your phone got wiped over wifi, which would require access to your Google account. It's just odd that you get errors, which normally shouldn't happen if someone would use the erase a lost Android device function.
It's also possible that your backup from your GAccount is simply corrupted (many people had issues with random reboots). You should try and set up your (replacement) phone anew without any backup, maybe that can fix your issue.
Beyond that Google account thing-y, anything else is highly unlikely. Even specialized companies have serious issues getting into a modern smartphone, lest alone an Android 12 phone with a Google Server grade Titan m2 chip. The newer the firmware, the less likely the chance that someone from the outside could get in, especially with a phone like a Pixel that isn't very common. Most security firms/govermental agencies can only abuse older, known security loopholes. It's more likely that very popular phones like a Samsung or IPhone are targets from "the bad guys", since there will be bigger payoff for breaking the security of those phones, since there is a greater pool of users to target. Most hacks I've witnessed weren't random, they were targeted. Ask yourself: Am I worth the trouble of getting hacked? Do you have anything of interest on your phone that would warrant an excessive use of resources? Managing to hack a Pixel is not only unlikely in terms of the security you need to breach, but also in terms of the potential payoff in relation to the necessary knowhow and resources. It's just "not worth it".
What you should do immediately, just in case, is secure your Google account. Change your password. Maybe even change your two-factor authentication, if you have one (sms is not secure, use a token generating software/device). Change the wifi password from your girlfriend and check the list of connected devices. make a list of these connected devices + history (find that in the rooter software) and check them against the devices you know of. Also check the list of connected devices to your GAccount. Use the option to log out ALL devices from your Google account, so only your device is connected.
Do any other people have access to your phone? Do any other people know your passwords? Does your girlfriend has access? Do any other people have biometric security saved on your phone? Do you trust your girlfriend completely?
Make sure you use a special, new password for your GAccount, never reuse old ones that you have used somewhere else. Also check your emails on https://haveibeenpwned.com/
Beyond that, if you are not doing already, use a password manager.

Wait a sec. Verizon sent you a new (refurbished probably but new nonetheless) phone and when you turned it on weren't you greeted with the startup menu? Am I missing something?

This, among many other things, is one of the reasons I use GrapheneOS and NO gooble services (despite all the attention they give to sandboxed gooble services).

your google address was found on that site for another service and you used the same password for both services, correct?
despite what some believe, your google account will not get hacked unless your password is insecure (ie. leaked or insufficient with 2FA). anything less and your asking for trouble (also using GrapheneOS).

Question How much should i worry about stolen device?

First of all never have lost/stolen phone , but with the new lineageOS on my poco f3 i worried about losing my phone and leting easy access to the thiefs.someone who finds it . Is the lineageOS encryption decent enought? Dont really know how to do the basics for not leaving too easy but i want to know if the default acomplishes that without more tinkering

Can't comment on the security of lineage over other roms, I'm guessing they much of a muchness with encryption.
But, if you're that worried have you thought about an anti theft app such as Cerberus? There may well be other, cheaper options... Cerberus is 5EUR per year. Once installed its a very powerful app, or at least was when I used it years ago. You can hide the app from the app drawer and take other measures to prevent uninstall. Once it's on your phone you can remotely control your device or track it, even take pictures of the person trying to unlock your phone and forward those pics to a backup number or email. You can trigger alarms, lock the device or... Worst case scenario you can remotely wipe the device after logging into your account on cerberus website. I think even if they insert another sim the app being buried/hidden on your phone can email you the new number etc etc. There's a number of commands you can do /send.
Just to add, I'm not affiliated to the app in any way. I used to use it but like you have never lost a phone so gave up on it.
https://www.cerberusapp.com/

thanks for the info , been out from custom roms for a while and i forgot that app for complete

LineageOS uses a decent encryption as long as you choose a strong password. I would't worry as long as your not the target of a government
A decent password is very important tho!

Question I'm hacked

My girlfriend can see everything I do on my phone, even listen in to my surroundings and spy on me with my camera. I've looked at all the running processes and I can't find the malware. Any advice besides a system reset? Thanks

She's probably just has your password mate. Change it or factory reset your device. If that doesn't work find a new gf.

Believe me it's not just the password. She's installed some kind of parental Spyware like MSpy

If you're sure that's what she has done, and not just a bit paranoid, then you should be able to find it if you got into safe mode. At least I believe so.

I'm 100% convinced that's what she's done but I'm not that tech savvy when it comes to phones so I'm not sure which processes are part of the Android OS and which processes are the spy app.

Ditch gf.
Factory reset, will purge anything she loaded. The bootloader is locked so the only thing she could hack is the user data partition, a factory reset clears this.
Delete Google and Samsung accounts in settings>factory reset from settings not recovery menu>don't set up your Google account initially>change Google and Samsung account passwords on another computer (PC or Mac), write down passwords and make them complicated, setup the Google account on phone then.
It is clean. Be careful what you then load and who you give access to your phone if anyone.

I had a phone bought on eBay which I think it was cloned
It was the Xiaomi mi mix fold 2. I kept sending me messages please close the screen mirroring ect..I tried to reset it but nothing worked. Someone cracked the ROM in my opinion. eBay refunded me in full. I think you shall better buy a new phone

If you're paranoid:
reset your computer without a network connection.
reset your phone and don't connect to wifi yet.
reset your home wifi modem/router
connect your devices and use a strong password.
After this only a specialist can hack you.

No reason to replace the phone if it's a stock Samsung and it factory resets. As long as Knox isn't tripped it's still running with a stock rom and bootloader that haven't been altered and are still secure.

After reset it can't be accessed until account info is entered. My solution bypasses that entirely.
If he factory resets from recovery without first deleting Google and maybe Samsung accounts from the phone he may get locked out by FRP!
FPR is more wicked than any bad gf...
In Samsung's it's always best to factory reset from Settings rather than the boot menu. I redundantly make sure FRP won't be invoked by also deleting the accounts before the reset whenever possible*
*a boot loop or total system crash trashes this option, better hope the account password works...

They don't; most victims inadvertently install the malware themselves. Social media sites like WhatsApp, Tiktok etc are hunting grounds for hackers. Poor settings and app selection, clumsy browsing habits, side loading, unlocked bootloaders, no firewall in use, being careless what's downloaded, not keeping email in the cloud, allowing others physical access to the device, sharing drives, using unsecured wifi hotspots, not using Android 9 or higher... among others.
