Android Beta for Pixel offers you a simple way to try pre-release versions of Android, and test drive our new features. The feedback you provide will help us identify and fix issues, and make the platform even better. Enrolled devices will automatically receive updates for the latest beta version of Android. Learn more about eligible devices.
You will not be able to unenroll and revert back to a stable public version of Android without first wiping all locally saved data on your device. You may also encounter issues restoring a backup. We recommend reviewing the latest release notes for Pixel phones before enrolling in Android Beta.
Your device eligibility and current build determine which program options are available for enrollment. Devices on a public stable build will see multiple program options to select from when more than one beta program is available.
Important: If, after opting out, you only see one program option to enroll in, you will need to first apply the stable public version (will require a data wipe) in order to see multiple enrollment options. This only applies when more than one beta program is available.
View devices to find the device you want to switch and click Opt out. Your device will receive an update within 24 hours that will wipe all user data and install the latest stable public version of Android. Once you install the public update, your device is ready to enroll in another beta program.
Important: Your device may get automatically removed from the beta program it is enrolled in and either get moved to the public release track or to another beta program track for the following reasons:
Like the names of most other Greek letters, the name of beta was adopted from the acrophonic name of the corresponding letter in Phoenician, which was the common Semitic word *bayt ('house', compare Arabic: بيت bayt and Hebrew: בית byit). In Greek, the name was βῆτα bta, pronounced [bɛ̂ːta] in Ancient Greek. It is spelled βήτα in modern monotonic orthography and pronounced [ˈvita].
Beta should not be confused with standard deviation (or the semi-variance, which considers only negative returns): the preferred measure of the "riskiness" (historical volatility of returns) of a financial asset or a portfolio in isolation.
Beta can be calculated as the covariance of a financial asset (or portfolio) with its benchmark index, divided by the variance of the benchmark index. Since the industry of finance gravitates towards return generating activities, typically the historical returns (percentage changes) are used in the calculations Beta values (among others).There are numerous other methods a financial analyst can employ to derive Beta values if historical prices are not available.Beta values change over time (company restructuring; industry sentiment; endo/exogenous factors). Beta values also vary, conditional on the time period used in calculating a Beta value. Beta values can be negative, which infers the existence of financial assets which historically, tended to move in opposite directions to one another by some unit value. It would seem these are the optimal "hedges" to offset market-draw-downs, during periods of market-stress and poor liquidity Beta values can vary dramatically, and previously low or even negative correlations converge to "1".
Beta male, or simply beta, is a slang term for men derived from the designation for beta animals in ethology, along with its counterpart, alpha male.[4][5] The term has been used as a pejorative self-identifier among members of manosphere communities, particularly incels, who do not believe they are assertive or traditionally masculine, and feel overlooked by women.[6][7] It is also used to negatively describe other men who are not assertive, particularly in heterosexual relationships.
In some high-quality typesetting, especially in the French tradition, a typographic variant of the lowercase letter without a descender is used within a word for ancient Greek: βίβλος is printed βίϐλος.[8]
"Beta" can be used to refer to several consumer and professional videotape formats developed by Japan's Sony Corporation. Although similarly named, they are very different in function and obsolescence.

For beta to provide useful insight, the market used as a benchmark should be related to the stock. For example, a bond ETF's beta with the S&P 500 as the benchmark would not be helpful to an investor because bonds and stocks are too dissimilar.
While beta can offer useful information when evaluating a stock, it does have some limitations. Beta can determine a security's short-term risk and analyze volatility. However, beta is calculated using historical data points and is less meaningful for investors looking to predict a stock's future movements for long-term investments. A stock's volatility can change significantly over time, depending on a company's growth stage and other factors.
Beta can provide some risk information, but it is not an effective measure of risk. Beta only looks at a stock's past performance relative to the S&P 500 and does not predict future moves. It also does not consider the fundamentals of a company or its earnings and growth potential.
A Beta of 1.0 for a stock means it has been as volatile as the broader market. If the index moves up or down 1%, so too would the stock, on average. Betas larger than 1.0 indicate greater volatility - so if the beta were 1.5 and the index moved up or down 1%, the stock would have moved 1.5%, on average. Betas less than 1.0 indicate less volatility: if the stock had a beta of 0.5, it would have risen or fallen just half a percent as the index moved 1%.
The software release life cycle is the process of developing, testing, and distributing a software product (e.g., an operating system). It typically consists of several stages, such as pre-alpha, alpha, beta, and release candidate, before the final version, or "gold", is released to the public.
Pre-alpha refers to the early stages of development, when the software is still being designed and built. Alpha testing is the first phase of formal testing, during which the software is tested internally using white-box techniques. Beta testing is the next phase, in which the software is tested by a larger group of users, typically outside of the organization that developed it. The beta phase is focused on reducing impacts on users and may include usability testing.
Some software, particularly in the internet and technology industries, is released in a perpetual beta state, meaning that it is continuously being updated and improved, and is never considered to be a fully completed product. This approach allows for a more agile development process and enables the software to be released and used by users earlier in the development cycle.
Pre-alpha refers to all activities performed during the software project before formal testing. These activities can include requirements analysis, software design, software development, and unit testing. In typical open source development, there are several types of pre-alpha versions. Milestone versions include specific sets of functions and are released as soon as the feature is complete.[citation needed]
The alpha phase of the release life cycle is the first phase of software testing (alpha is the first letter of the Greek alphabet, used as the number 1). In this phase, developers generally test the software using white-box techniques. Additional validation is then performed using black-box or gray-box techniques, by another testing team. Moving to black-box testing inside the organization is known as alpha release.[1][2]
Alpha software is not thoroughly tested by the developer before it is released to customers. Alpha software may contain serious errors, and any resulting instability could cause crashes or data loss.[3] Alpha software may not contain all of the features that are planned for the final version.[4] In general, external availability of alpha software is uncommon for proprietary software, while open source software often has publicly available alpha versions. The alpha phase usually ends with a feature freeze, indicating that no more features will be added to the software. At this time, the software is said to be feature-complete. A beta test is carried out following acceptance testing at the supplier's site (the alpha test) and immediately before the general release of the software as a product.[5]
A feature-complete (FC) version of a piece of software has all of its planned or primary features implemented but is not yet final due to bugs, performance or stability issues.[6] This occurs at the end of alpha testing in development.
Beta, named after the second letter of the Greek alphabet, is the software development phase following alpha. A beta phase generally begins when the software is feature-complete but likely to contain several known or unknown bugs.[7] Software in the beta phase will generally have many more bugs in it than completed software and speed or performance issues, and may still cause crashes or data loss. The focus of beta testing is reducing impacts on users, often incorporating usability testing. The process of delivering a beta version to the users is called beta release and is typically the first time that the software is available outside of the organization that developed it. Software beta releases can be either open or closed, depending on whether they are openly available or only available to a limited audience. Beta version software is often useful for demonstrations and previews within an organization and to prospective customers. Some developers refer to this stage as a preview, preview release, prototype, technical preview or technology preview (TP),[8] or early access.
