How to completely delete data on Android phone?

Is there any way that could completely delete data on Android phone without recovery? I tried to restore my phone to factory and data was gone, but when I try to scan my phone with a tool called Wondershare dr.fone, I was surprised that all the data scanned out, that means they're be recoverable! So, I need to permanently erase my phone data. any suggestion?

The reason is that deleted data will not gone immediately on disk unless it is overwritten by new data. To securely wipe Android device, you have to write un-structured data to the drive for at least two times.
