1. When you refresh/upgrade the system or restore the factory settings, you will erase the data of the mobile phone, including the software.
2. Now all the software is downloaded in the app store. Generally speaking, in order to save mobile phone space, the software in the app store will be automatically deleted after downloading, but when you want to reinstall the software or collect a software to share with your friends, you can't remember where to download it or there is no download address.
At present, there are many backup software, both on PC and mobile. If you find the PC troublesome, try the backup software on the mobile. Today, I also introduced the method of backing up mobile phone software.
The mobile phone backup software used here is the famous "Cheetah Cleaning Master". I believe that many small partners have this software in their mobile phones. Cheetah cleaning master is famous for cleaning up mobile phone garbage. Efficient and fast garbage cleaning and memory acceleration are well known and popular, and the backup software function is also very useful.
first step
Open Cheetah Cleanup Master, find "Software Cleanup" in the lower right corner of Sigongge at the bottom of the homepage, and click Enter.
Second step
After entering, you can see the software installed in your lock here. You can choose different categories such as "by frequency", "by date" and "by software size" for easy searching.
Find the software you want to back up (take "microdisk" as an example), and click the box behind the software size to check it.
Third step
Click the "Backup" button on the left (white) at the bottom of the page, don't click "Uninstall", or you will understand.
After selecting backup, the software starts backup. The backup speed depends on the size of the software. Don't worry.
Fourth step
After the backup is completed, "Backup succeeded" and the saving path (/storage/sdcard0/cleanmaster _ cn/backup) will pop up.
Step five
Open the file manager in your phone. If not, you can download an ES file browser or RE file manager.
Locate the cleanmaster_cn folder (usually in the root directory of the file manager) and open it.
Step 6
Open the backup folder under the cleanmaster_cn folder, and you can see the software you backed up!
