Is it easy to upgrade iPhone 6 to ios10.3.3?

After the update, I didn’t feel any obvious lag or fever. It's just a little bit uncomfortable to use.

The biggest feeling after the update is that

1. The color scheme is not good-looking and the lock screen sound has changed. Maybe you can get used to it.

2. Messaging and iMessage have more ways to play, but they are definitely not as fun as WeChat.

3. You can delete some of the apps that come with it, such as watches that you don’t need. But deleting it doesn’t leave much room.

4. Alarm clock and health, these two have some changes.

5. To unlock, you must press the home button instead of swiping the screen.

6. I heard that Siri is smarter than before and can link to third-party applications. I don’t know how to use it. The map is slightly better than before.

In iOS 10.3, Apple fixed a major security vulnerability in Safari, which allows hackers to display pop-ups in an infinite loop in Safari, eventually leading users to a fake law enforcement agency website and alerting users If there is an illegal act, you must pay a fine before you can continue to use all Safari functions normally. It is mainly targeted at users who view pornographic content, download pirated songs, etc. on the Internet. During this period, the attacker will also display threatening information and coerce users to pay. This vulnerability has been fixed in iOS 10.3.

The official version of iOS 10.3 takes up less memory, adds the new Apple file system APFS, optimizes flash/SSD storage, better encrypts the device, and frees up at least 2GB for the system. After the update, Xiu Mei’s iPhone actually has more than 2G of space. This function can be said to be a big surprise for 16G users. After all, at least a few less apps can be uninstalled.

The official version of Siri in iOS 10.3 has become smarter and more relevant to life. Siri can cooperate with payment applications to pay and check bill status. It can also cooperate with ride-hailing applications such as Didi to reserve a vehicle, and can cooperate with car horn applications to check the fuel level and car lock status, and can turn on the lights and honk the horn. Moreover, users can call "Hey Siri" to quickly bring up the Siri function when the phone's screen is on. However, the recognition rate of the "Hey Siri" wake-up function when the iPhone's screen is on and unlocked is obviously higher than when the phone's screen is on and unlocked.
