IT Home News January 23 Tencent Wechat team pushed iOS 7.0.3 to iPhone and iPad users yesterday, fixing some known problems and showing changes in the small program interface on the home page. In addition, IT Home noticed that compatibility of Weixin iOS version requires iOS 9.0 or higher. The lowest supported models have been upgraded to the iPhone 5s, the iPhone 6, the iPhone 6Plus and so on. They no longer support the iPhone 4s, the iPhone 5, and the iPhone 5c.
After the release of iOS 11 in September 2017, Apple officially abandoned 32-bit applications. After updating, 32-bit applications will not be able to start. When it tries to open, iOS 11 will pop up a pop-up box, indicating that App needs to be upgraded to be able to use. Nowadays, many applications begin to upgrade system restrictions and no longer support 32-bit processor versions.
Apples iPhone 5s, launched in September 2013, features the first new 64-bit A7 processor to support upgrades to the latest iOS 12 system.
