Apple releases the fifth beta version of iOS 12.2: improve running speed
Today, Apple released the fifth beta version of iOS 12.2, just a week after last week's beta.
this new beta version, Apple said, has improved the speed of the device, and has also modified a lot of Bug. Previously upgraded to iOS 12.2 beta, AT&T users can see the new 5G E icon, replacing the standard LTE icon. Because iPhone does not support 5G, this icon puzzles consumers, but in the final analysis it is only AT&T 's 4G network.
There was also news that Apple might add dark mode to iOS 13, which is said to be similar to the current "dark mode" on macOS Mojave, turning the window interface black for users who work at night.
for iPhone (except for XR), Apple should have joined the dark mode a long time ago, because it's better for the OLED screen, which saves more power. If Apple wasn't ready at the time, maybe after macOS, they should be ready.
