CTOnews.com, Oct. 29, CTOnews.com reported earlier this month that the Pixel 7 series can only run 64-bit apps, and now Google has officially confirmed this news.

CTOnews.com learned that Google revealed some information about its Pixel 7 and Pixel 7 Pro phones in a blog post on its developer's website. According to Google, the Pixel 7 series is the first ever pure 64-bit Android phone.

Google said that in order to achieve this "feat", various changes need to be made in "the entire platform, tools, Google Play and, of course, applications".

So what good is this for users? Google points out that 64-bit applications run faster than 32-bit applications because they can use additional registers and instructions that 32-bit applications cannot use. In addition, newer CPU provides up to 25% performance improvement when running 64-bit code, and some processors even give up support for 32-bit code altogether.

In addition, it can help improve security. Larger address space makes defenses such as ASLR more effective, and free bits can be used to protect the integrity of the control flow. These countermeasures can reduce the chances of intruders taking control of the equipment.

Google also said that removing support for 32-bit code could save up to 150MB's RAM because the operating system uses that memory even when 32-bit applications are not running. These memory savings mean that memory shortages are less likely to occur, which means that background killings are less common.

For developers, developers can use better tools, such as HWASan, to detect memory errors and improve the quality of applications. For manufacturers, pure 64-bit devices halve CTS test time, making it faster and easier for suppliers to update their devices.

Google also said that pure 32-bit devices are still important for Android Go, Android TV and Android Wear, and Google Play will continue to provide 32-bit applications for pure 32-bit devices.
