Nobody will get any information about you or the time you were near them. The app uses this one-time key to alert anonymously other app users that they were exposed. You can choose to upload the random codes your phone sends you. App users can also enter details to help narrow down when they were likely most infectious.

Those details tell the phone which random codes to upload. If the user chooses not to provide details, the app uploads the random codes from the last 14 days.

Rooting an Android phone lets the owner add, edit or delete system files, which in turn lets them perform various tweaks and use apps that require root access. Advantages of rooting include the possibility for complete control over the look and feel of the device. As a superuser has access to the device's system files, all aspects of the operating system can be customized with the only real limitation being the level of coding expertise. Rooting allows the user to obtain privileged access to a phone. It does not allow a user to install a new OS custom firmware or custom ROM or recovery image, and it doesn't allow a phone that locked to a certain carrier to be used on another one.

Related operations allow these. Bootloader unlocking is sometimes a first step used to root the device; however, it is not the same as rooting the device. Nonetheless, people still perform this operation, as unlocking the bootloader allows users to install custom ROMs.

The first step to do this is to generally to set up OEM unlocking, [19] and then to follow manufacturer specific instructions.

SIM unlocking allows a phone that is locked to a certain carrier to be used on a different carrier. The instructions vary per device and carrier, but this might be done by first requesting the carrier to unlock the phone or purchasing an unlock code online. Some rooting methods involve the use of a command prompt and a development interface called the Android Debug Bridge also known as ADB , while other methods may use existing vulnerabilities in devices.

Due to similarly modeled devices often have a multitude of changes; rooting methods for one device when used for a different variant can result in bricking the device. Systemless root uses various techniques to gain root access without modifying the system partition of a device. Some root applications may include a "hiding" function, which makes attempts to mask the effects and results of rooting, often by whitelisting certain applications for the root or blocking access to affected files.

However, hardware-backed SafetyNet versions may be triggered by systemless rooting, as well as in unrooted devices shipped without Google Mobile Services GMS. The distinction between "soft rooting" through a security vulnerability and "hard-rooting" by flashing a su binary executable varies from exploit to exploit, and manufacturer to manufacturer.

Soft-rooting requires that a device be vulnerable to privilege escalation , or replacing executable binaries. Hard-rooting is supported by the manufacturer, and it generally only exposed for devices the manufacturer allows. The process of rooting varies widely by device but usually includes exploiting one or more security bugs in the firmware of i.

Then a modified firmware update that typically includes the utilities needed to run apps as root can be installed. For example, the su binary such as an open-source one paired with the Superuser [28] or SuperSU application [29] can be copied to a location in the current process' PATH e.

A third-party supervisor application, like Superuser or SuperSU, can then regulate and log elevated permission requests from other applications. Many guides, tutorials, and automatic processes exist for popular Android devices facilitating a fast and easy rooting process. The process of rooting a device may be simple or complex, and it even may depend upon serendipity. For example, shortly after the release of the HTC Dream HTC G1 , it was discovered that anything typed using the keyboard was being interpreted as a command in a privileged root shell.

Although Google quickly released a patch to fix this, a signed image of the old firmware leaked, which gave users the ability to downgrade and use the original exploit to gain root access. Some manufacturers, including LG, HTC, and Motorola, provide official support for unlocking the bootloader, allowing for rooting without exploiting a vulnerability.

The Google Nexus line of devices can have their bootloader unlocked by simply connecting the device to a computer while in bootloader mode and running the Fastboot protocol with the command fastboot OEM unlock. In the past, many manufacturers have tried to make non-rootable phones with more elaborate protections like the Droid X , but exploits are usually still found eventually.

There may be no root exploit available for new, or outdated phones. Until , tablet and smartphone manufacturers, as well as mobile carriers, were mainly unsupportive of third-party firmware development. Manufacturers had expressed concern about improper functioning of devices running unofficial software [34] and related support costs. Moreover, firmware such as OmniROM and CyanogenMod sometimes offer features for which carriers would otherwise charge a premium, such as tethering.

Due to that, technical obstacles such as locked bootloaders and restricted access to root permissions have commonly been introduced in many devices. The Nook Tablet 1. However, as community-developed software began to grow popular in the late to early , [37] [38] and following a statement by the Copyright Office and Librarian of Congress US allowing the use of "jailbroken" mobile devices, [39] [40] manufacturers and carriers have softened their position regarding CyanogenMod and other unofficial firmware distributions.

Some manufacturers, including HTC, [41] Samsung , [42] Motorola [43] and Sony Mobile Communications , [44] actively provide support and encourage development. In , the need to circumvent hardware restrictions to install unofficial firmware lessened as an increasing number of devices shipped with unlocked or unlockable bootloaders, similar to the Nexus series of phones.

Device manufacturer HTC has announced that it will support aftermarket software developers by making the bootloaders of all new devices unlockable. These are similar in practice to Nexus devices, but for a premium and with no contract discounts.

In , Samsung released a security service called Knox , which is a tool that prevents all modifying of system and boot files, and any attempts set an e-fuse to 0x1, permanently voiding the warranty. International treaties have influenced the development of laws affecting rooting. The American implementation is the Digital Millennium Copyright Act DMCA , which includes a process for establishing exemptions for non-copyright-infringing purposes such as rooting. The European Copyright Directive implemented the treaty in Europe, requiring member states of the European Union to implement legal protections for technological protection measures.

The Copyright Directive includes exceptions to allow breaking those measures for non-copyright-infringing purposes, such as to run alternative software, [46] but member states vary on the implementation of the directive. In , Electronic Frontiers Australia said that it is unclear whether rooting is legal in Australia, and that anti-circumvention laws may apply. In November , Canada amended its Copyright Act with new provisions prohibiting tampering with digital locks, with exceptions including software interoperability.

There had been several efforts from to to amend the Copyright Act Bill C, Bill C , and Bill C to prohibit tampering with digital locks, along with initial proposals for C that were more restrictive, [49] but those bills were set aside. In , Michael Geist , a Canadian copyright scholar, cited iPhone jailbreaking as a non-copyright-related activity that overly broad Copyright Act amendments could prohibit.

The Free Software Foundation Europe argues that it is legal to root or flash any device. The law Copyright and Related Rights Regulations makes circumventing DRM protection measures legal for the purpose of interoperability but not copyright infringement. Rooting may be a form of circumvention covered by that law, but this has not been tested in court. India's copyright law permits circumventing DRM for non-copyright-infringing purposes. New Zealand's copyright law allows the circumvention of technological protection measure TPM as long as the use is for legal, non-copyright-infringing purposes.

Rooting might be legal in Singapore if done to provide interoperability and not circumvent copyright, but that has not been tested in court. The Unlocking Consumer Choice and Wireless Competition Act guarantees that consumers can unlock or let others unlock their phones. The U. Copyright Office granted an exemption to this law "at least through ".
