Why do I need to hard reset Android?
Restoring your phone to factory settings should only done if necessary. Transferring files and downloading and installing apps again can be time-consuming, but there are times when a hard reset is the only way to solve a problem.
If your phone is running slowly, erasing your data could free up a lot of space and speed up response times. You should first try deleting apps and files individually to see if this solves the problem.
If a recent update is causing problems, restoring to default settings could undo this. However, some updates may be necessary for apps to run correctly.
If you are selling your phone or giving it to someone else, a factory reset will erase your personal data and sign out from your accounts. This helps to keep your identity and data secure. Double check that all personal data has been removed before you part with the phone.
Does factory reset remove viruses?
If you have infected files on your OPPO phone, a hard reset of your device should erase these.
However, if you've backed up your data before resetting, you should check whether the virus is present in your backups. Use a virus scanner to check your storage drive and remove any possible infections.
You should also run a virus check after you reset your phone to make sure and check your antivirus settings to prevent further infections.
How often should I factory reset Android?
You don't have to factory reset your phone unless it's developed a problem, but there can be benefits to doing a hard reset occasionally, especially if you download a lot of apps and files.
If you think your phone is too full, and you've saved what you really need, starting with a clean slate every 3 to 4 months could speed things up and improve your user experience. Just keep in mind that reinstalling apps and transferring files back from storage could take a while.

Recover deleted files on Android after factory reset
If you didn't have the chance to backup Android before you performed a factory reset, there's still a chance you could recover your lost data.
To do this, your phone must be rooted and you will need a third-party app designed to recover files and data. These should only be downloaded from trusted sources such as the Google Play Store.
First, check your reset phone to see if the data is still there. There's a chance you didn't choose to wipe all data when you reset Android to factory settings.
If you can't find what you're looking for, you can try the following:
1. Download a data recovery app and follow its instructions.
2. The app will test that your phone is rooted properly.
3. If it is, you can select the type of data you want to recover, or select all options. There may also be an option to permanently delete data, so be careful not to select this.
4. Your data should then be restored.
