Which Mobile Forensics Tool can completely WIPE OUT the mobile phone?

I have found the following two tools which perform the data wipeout.

try and share your experiences.

"Wiping" out a phone is the opposite of computer forensics, in my opinion, which is the science of preserving and analyzing electronic evidence.

If one needs to "wipe out" a phone, it can be as simple as performing a factory reset on an iPhone, for example.

However, smartphone data can also reside in the cloud (iCloud) and in backups on a workstation (iTunes), so in order to truly destroy all copies of data on an iPhone, one would need to perform a factory reset on the iPhone itself, use iCloud to delete all iCloud stored mobile backups, and permanently delete (meaning overwriting with zeroes) an iTunes mobile backups stored on workstations.

Android phones do not have an iCloud equivalent cloud based mobile backup service, but Android data can be backup up to Google Drive (see WhatsApp), so in addition to performing a factory reset on an Android phone, one would need to identify and permanently delete and cloud stored app specific data such as WhatsApp chats backed up to Google Drive.

@unallocatedclusters Thank you for the detailed reply. It is really helpful to understand. 

Even you try to delete all data, in phone is extremely easy. there are tools that overwrite 7 (seven) times each bit. You have to clean backups on the cloud. BUT, it is impossible to delete generated traffic in whatsapp (it is store permanent on whatsapp servers!) or similars.

So, technically, there is NO tool that could wipe 100% sure a phone in the world.

To simple to just say phone. Phone can be android, android, encrypted not encrypted, FDE, FBE, ect.  

The tools you mention is rather a scam than forensic tools

I think the question should really be .........

Will it blend?
