How does iphone4 recover deleted messages?

How to recover from deleting short messages by mistake? What should I do if I accidentally deleted the important short messages in my mobile phone when I was cleaning the memory of my mobile phone just now?

Step by step method

1. Just shake your iphone a few times and a window will pop up. Select "Cancel Typing" to delete everything without pressing the delete key for a long time.

2. If you want to restore the content you just deleted, shake the iphone and select "Retype", and the content you just deleted will come back; If it is just pasted, you can "undo pasting" by shaking it. This function is good! It is also very convenient to operate, but be careful not to shake the phone away!

3. When using the iphone4, be sure to back up the files in the phone regularly. Because you can't tell when something will go wrong with your mobile phone, it's a good habit to back it up regularly. System problems suddenly appear and can be recovered after handling. If you don't have good backup habits, it will be very troublesome if there is a problem. Some things need to be re-entered.

4. It's a good habit to back up mobile phone data frequently. Just like often backing up the data in the computer, this not only prevents the loss of mobile phone data. And you don't have to worry about whether the data in the mobile phone can't be recovered. It's good that iphone4 has this undo function.
