Can we wipe an Android phone completely using Encryption and Factory Wipe? (Samsung Galaxy S7 to be exact)
I have a Samsung Galaxy S7. I believe cell phones use flash storage (like SSD) and its not as secure as NOn-SSD wiping. https://www.quora.com/What-kind-of-storage-do-phones-use-i-e-SSD-HDD-and-flash
For example with Computers, I know that SSD drives that are already encrypted, is relatively safe to write to them and nobody can access your encrypted data- as long as nobody knows your password and nobody has access to your computer/HD or no malware etc. But If you write to an SSD drive unecrypted, even if you wipe it and encrypted it after, its not as secure. So wiping is not as 100% effective. So I am concerned about Cell Phone "hard drive storage" being flash storage: https://www.quora.com/What-kind-of-storage-do-phones-use-i-e-SSD-HDD-and-flash
My queston is, according to this guide https://www.ubergizmo.com/how-to/wipe-android-phone-tablet/
it says you simply Encrypt your cell phone with a really good password that nobody can figure out. and then do a factory wipe and that should wipe your cell phone 100% clean, so anything on your cell phone previously is 100% wiped. Is this true/accurate?
These guides also say something similar: https://www.psafe.com/en/blog/data-actually-gone-wipe-phone-clean/ Quote from this website: "After the encrypting process is complete, you hit the “Factory Reset” button, which makes your phone 100% clean and ready to sell."
Another layer of protection. My phone also has a program called "Shreddit." that supposedly wipes your phone clean, so if we do Encryption, Factory reset + use this program with US DOD 3 pass wipe Scheme..... should all the existing data on my phone be pretty much wiped and not accessible and recoverable? http://apps.palmtronix.com/shreddit/android/
Thanks guys, Thank you in advance!
