On September 2, the Gold Label Alliance, launched by Alibaba/Baidu/Tencent and OPPO/vivo/Xiaomi, released the Notice on the Removal of Only 32bit Applications.

The domestic Android ecosystem has finally basically completed the conversion of 64 bit apps.

Official data: As of August 23, 2024, OPPO、vivo、 The full adaptation rate of Xiaomi and Lenovo software stores is more than 99.29%, and there are still 4000+key applications that affect users' daily life that have not yet been adapted to 64 bits.

Turning to pure 64 bit can improve performance, energy efficiency and security.

To switch to pure 64 bit, we need 64 bit architecture of hardware+64 bit App of software

On the hardware side, Apple suddenly released the first 64 bit architecture SoC on the mobile phone in 2013 - Apple A7 (iPhone 5S launched for the first time), which caught Qualcomm by surprise. Subsequently, the 64 bit architecture of Qualcomm made the Snapdragon 810 "glowing" released at the end of 2014 famous.

In order to accommodate the app ecosystem, Arm has been updating the hardware architecture compatible with 32-bit apps, and it will not fully turn to 64 bit until the X4/A720/A520 in 2023 (corresponding to Snapdragon 8 Gen 3 and Tianji 9300).

In terms of software, Apple stopped supporting 32-bit apps in the iOS 11 era less than five years after the release of A7 (it announced in 2017 that it would completely stop supporting 32-bit apps on January 1, 2018).

The overseas Android ecosystem has basically popularized 64 bit apps many years ago. However, the domestic Android ecosystem, including many leading manufacturers, has always been dependent on the 32-bit. The result is that from 2015 to 2024, it took 9 years for the mainstream Android ecosystem in China to get off the pure 32-bit App

PS： The last Android system that only supports 32-bit CPU is Android 4.4 in 2013;

PSS： After Android 5.0 in 2014, the Android camp is compatible with both 32-bit and 64 bit applications.

PSSS： The Snapdragon 8 Gen 3 and Tianji 9300 are both pure 64 bit architectures, but Qualcomm and MediaTek have done translation, and most 32-bit applications can be installed on the systems of Xiaomi/vivo/OPPO and other large manufacturers, while ZTE/Nubia/Red Devil/Weilai and other small manufacturers do not provide similar functions.
