By default a simple 'factory reset' will erase all your phone internal memory data. And it's not recoverable. But not applicable to MicroSD cards used in mobiles.can any pls tell me what is the best way to format a phone or ssd so the data cannot be recovered after selling it? does formatting multiple times help?
Thanks I was not aware about this.SSD and phone are different class of products. Why have you put them in the same statement with an "or"? It's unclear what you're expecting.
As for phones, all android phones released in the past 5 or so years are encrypted by default. Once you reset the phone, old data becomes irrecoverable, deleted or not. Note than this applies only to internal memory.
thanks for your reply. because i had no idea they are different, i thought u can use the same method.SSD and phone are different class of products. Why have you put them in the same statement with an "or"? It's unclear what you're expecting.

thanks. and can you pls tell me what software to use for ssds, preferably the one which are free.By default a simple 'factory reset' will erase all your phone internal memory data. And it's not recoverable. But not applicable to MicroSD cards used in mobiles.
For SSD you need specialized software to wipe clean the data, but relatively much easier than HDDs.
Your data is encrypted. On factory reset, the encryption key, which itself is protected by your pin or pattern, gets deleted, rendering all other data unreadable. This is effectively a permanent deletion as there is no way to read the data on the storage anymore.permanently delete all data?

Is factory reset for realme c25 (4gb/128 gb) enough to permanently delete all data?
Interesting..not have access to the tools and methods that a forensic lab would have.

I agree it is a good suggestion but technically I don't think disabling pin/lock pattern before reset affect anything on android because pin/pattern is there to protect your primary encryption key without which it is not that your phone is not encrypted but rather that its primary encryption key is visible to anyone who can then use it to decrypt that data. Once phone is reset the original primary encryption key on the phone itself is deleted so it doesn't matter whether the pin/pattern was disabled earlier or not because after the reset that key doesn't exist anymore. What you are talking about data exposed from freshly reset phone I think it is most likely due to no encryption on the phone itself as there are many custom rom install tutorials/guides online which actually disable the device encryption for ease of installing/switching custom roms & many ppl blindly follow such tutorials/guides without understanding them enough.This reminds me of something very important: do not disable the pin/pattern lock before factory reset.
Some sellers/buyers will insist on it when you go to a shop to sell it to, this will decrypt the contents of your phone and then it's a simple matter of connecting the freshly reset phone to your computer to recover private photos and videos which then end up on the internet somewhere.
DBAN is meant for hdd not ssd which works entirely different from hdd on a fundamental level.If needed you can use data remover softwares like dban to securely erasing SSD or HDD.
Sorry,my bad have used it for HDD. Should have cross checked before posting.DBAN is meant for hdd not ssd which works entirely different from hdd on a fundamental level.
