Existing devices upgraded to Oreo, and new products launched with older SoCs, were exempt from this rule. The lack of after-sale support from manufacturers and carriers has been widely criticized by consumer groups and the technology media. Some commentators have noted that the industry has a financial incentive not to upgrade their devices, as the lack of updates for existing devices fuels the purchase of newer ones, an attitude described as “insulting”.

However, root access can be obtained by exploiting security flaws in Android, which is used frequently by the open-source community to enhance the capabilities of their devices, but also by malicious parties to install viruses and malware. Google engineer Patrick Brady once stated in the company’s developer conference that “Android is not Linux”, with Computerworld adding that “Let me make it simple for you, without Linux, there is no Android”. Ars Technica wrote that “Although Android is built on top of the Linux kernel, the platform has very little in common with the conventional desktop Linux stack”. An “All Apps” screen lists all installed applications, with the ability for users to drag an app from the list onto the home screen. Android devices boot to the home screen, the primary navigation and information “hub” on Android devices, analogous to the desktop found on personal computers. Android homescreens are typically made up of app icons and widgets; app icons launch the associated app, whereas widgets display live, auto-updating content, such as a weather forecast, the user’s email inbox, or a news ticker directly on the homescreen. A homescreen may be made up of several pages, between which the user can swipe back and forth.

A hacker could easily use the “Android system permissions” to fetch the account credentials in order to do so. Twitter confirmed that updating the app will restrict such practices. The vulnerability came by exploiting a bug in multitasking system and enabling malicious app to overlay legitimate apps with fake login screens that the users did not aware when handing security credentials. The users can also be tricked into granting additional permissions to the malicious apps, which later enable the apps to perform various nefarious activities, including interception of texts or calls and bank robbery.

The main hardware platform for Android is ARM (the ARMv7 and ARMv8-A architectures), with x86 and x86-64 architectures also officially supported in later versions of Android. The unofficial Android-x86 project provided support for x86 architectures ahead of the official support. Since 2012, Android devices with Intel processors began to appear, including phones and tablets. While gaining support for 64-bit platforms, Android was first made to run on 64-bit x86 and then on ARM64. Since Android 5.0 “Lollipop”, 64-bit variants of all platforms are supported in addition to the 32-bit variants. An unofficial experimental port of the operating system to the RISC-V architecture was released in 2021. Examples of these third-party stores have included the Amazon Appstore, GetJar, and SlideMe.
