Android: There are several ways to back up Android phone data.

Updating the ROM system is a great pleasure for Android mobile phone players, especially some popular mobile phones will always have folk experts to create rich third-party ROM resources for them, and get a higher system version, more functions or faster speed than the official ROM. However, system upgrades often require double erasure (clearing user data), resulting in the loss of our installed programs, game files or WeChat chat records. So, if you can back up the user data before the computer is updated, and then re-import it after the system is updated, isn't it equivalent to "resurrection in place", saving a lot of waiting time for reloading? Four data backup schemes 1. The PC client takes pea pods as an example. Turn on the USB debugging mode set by the mobile phone, and after connecting with the PC, click the "Backup Recovery" option in the list on the left side of the pea pods client, so that contacts, SMS and application data can be backed up to the PC. After the system with mobile phone is updated, use the recovery function of pea pods to import the mobile phone. 2. Mobile phone pre-installed software Many mobile phones will be pre-installed with official backup software. Take Lenovo K920 as an example, its own backup APP can complete the functions similar to pea pods client locally on the mobile phone, and save the backup data in the mobile phone. After the system is upgraded, it can be restored according to the reverse process. 3. Third-party APP If your mobile phone doesn't have backup software, you can use "titanium backup" to back up any program data after obtaining Root permission. For a game like eternity warriors, the program itself and the current archive (money, equipment, checkpoints, etc. ) games can be fully backed up, and there is no need to upgrade again after recovery. If you are worried that the mobile phone will become unstable after the system upgrade, you can consider a third-party recovery for the mobile phone (different brands and models have different ways of refreshing and recovery versions, so please search for specific tutorials yourself). In the third-party recovery, the whole system can be backed up and recovered, which is similar to the Ghost image of Windows system. I feel that the new system is not easy to use, and I can restore the image in Recovery to the state before the upgrade. It is suggested that all backup methods except PC client will save the backup data in the built-in storage space of mobile phone. In order to avoid automatically formatting the built-in storage space when upgrading the mobile phone, you must first copy the folder where the backup data is saved to the PC hard disk, just in case.
