Protect your privacy

Nothing OS introduces Private Space, designed to provide users with a secure environment to store and manage sensitive apps, files and photos. It acts like a digital safe, effectively protecting user privacy.

Features:
1. Additional authentication: to access Private Space, you'll need to go through additional authentication, such as a password, code or pattern, to ensure security.
2. Hidden apps: your apps in your private space don't appear in your regular app list, recent apps or notifications, making it impossible for others to view sensitive information even if they have access to your phone.
3. Separate Google account: you can create a dedicated Google account for your Private Space, providing further privacy protection and preventing private data from leaking into the main space.
You can open the private space from here: Launcher > App drawer > Private Space. Swipe right in the app drawer to enter (some languages may require a left swipe).

Note: Performing a factory reset will clear all applications, contacts, text messages and other data in your phone, which can't be restored after the operation. Please be sure to back up important data and migrate chat history from third-party applications such as WhatsApp in advance. The path is as follows: Settings > System > Reset options > Erase all data (factory reset) To keep your personal information safe, you will need to verify your lock screen / Google account password if your phone has a lock screen password or is logged in with a Google account. Ensure you have good internet connection to verify the account password and then follow the on-screen prompts.

Press the power button and volume+ button simultaneously, and a pop-up menu will be displayed. Then select Power to turn off the phone. Alternatively, swipe down from the top of the screen to access quick settings. Swipe down again to access the control centre and power button.

1. To set up screen-casting, swipe down twice from the top of the screen to access the expanded quick settings. Tap the edit (pencil) icon and drag the Screen cast tile up from the hidden tiles.
2. To start screen-casting (mirroring), swipe down to open the quick settings and locate the newly added Screen cast tile. Tap it once and select the target device to cast to. Ensure that both devices are connected to the same local network.

There are two ways to do this: 1) Swipe up from the homescreen, tap on Contacts, select the relevant contact, then tap the 3 vertical dots icon > Block numbers > Block. 2) Tap on the Dialer app and go to Contacts, select the contact, then tap the 3 vertical dots > Block numbers > Block.
