The weather flashed back in Ios7.

Hello, it's a system problem! At present, ios7 is only unstable and has many loopholes! Imperfect! Personally suggest demotion! When it is stable, it is an upgrade.

I said it from the UI, because visual aesthetics vary from person to person. After upgrading ios 7, there are many advantages, but the disadvantages can not be ignored.

Advantages:

1. Added gesture function. You can swipe right from the left edge of the screen to return to the previous interface.

2. The control center slides upward from the bottom of the screen, adding switch functions such as wifi, music and flashlight.

3. You can use the third-party input method. (But I'm not sure if there is a nine-grid input method.)

4: You can block incoming calls and text messages. (There is no doubt that it is true)

5. Added security function and bound Apple ID. Others must enter the correct Apple ID to activate, even if the system is refreshed, it is required to enter the Apple ID.

Disadvantages: 1, multitasking management has been replaced by real background running software. At present, there are devices with small memory besides iPhone 5, so the memory is obviously insufficient. (As a result, the operation is not smooth, and sometimes the keyboard won't pop up.)

2, power consumption, there is no doubt that this is certain. Shaking the mobile phone wallpaper in the real background is enough to increase power consumption.

3. Other shortcomings will be found and supplemented later.

Suggestion: personally, it is not recommended to upgrade unless you like the new UI and need to use the security function. In fact, ios7 has strict requirements on hardware, especially memory, and 4,4 S will be a bit insufficient.

I hope it helps you! Hope to adopt! thank you
