If you want to ensure that no one can recover the data in the future with a data recovery program, you can take additional precautions.

Install CClener on your computer, if not already existing. The free version is enough.

Connect your phone to your computer.

Open the CCleaner program. Go the “Drive Wiper” tag. Select the drive. Make sure that you are selecting the correct drive, that is the SD Card not the internal phone memory! Now choose the type of wipe you require. My suggested option is “Free Space Only”. Then choose the type of security you require. Simple Overwrite is ok for most situations. CCleaner will overwrite the free area. Wait to finish it. After finishing disconnect your phone from computer. Now you are safe to sell your phone.
