How to delete all the information off your mobile phone
The courier has just placed a box of shiny, shiny, new mobile phones on your desk for the team. Handsets in any one of 6 colors each looking for someone to press their belly into life. Suddenly your mobile seems old, its let you down, it’s no longer shiny. It doesn’t match your dress or ties like the new one does and that old processor, huh so slow. So, the days go by and your old mobile sits glibly looking unloved; forlorn in the corner.What about selling it? Good Idea.
HOLD ON A MINUTE, didn’t you read an article about mobile phones and identity theft, financial fraud, data piracy! How can a mobile phone be hacked by some nimbly fingered cyber-criminal for information?
It would appear that erasing information off some devices is not as simple as it first seems. It’s quite possible to purchase data recovery software packages, that your criminally minded cyber geek can use to resurrect deleted data from your mobile phone.
How can they use the information?
So what security controls do you have in place? Are you sure that the mobile phone now on sale is information free? You need to make sure that the phone is wiped and that all your private and sensitive business information, financial stuff, emails and other correspondence is erased totally off the phone.
Wiping an iPhone
Make sure you have an up to date back-up of your mobile, your iCloud account automatically makes a back-up for you at night (unless you’ve changed the settings). Backing up your information is a good idea just in case you lose your device, you can replace it, whether it's lost or damaged. You have two methods. iCloud and iTunes.
Connect up to a Wi-Fi network. Check that you have enough backup space in your account. Go to Settings, tap on the iCloud button. Push the iCloud Backup button.
Go to your iTunes account, select your device, click Back Up-Now. (Back up Apps, if you're asked)
Now for the erasing bit
Wiping an Android device
First, off the bat, you might consider using an Android data software to permanently erase your information; iShredder 5 is a popular App.
Otherwise, follow these steps for your android mobile phone*
Step 1. Make sure you have backed up everything.
Step 2. Take out the SIM card. SIMS carry a lot of information, contacts, call logs etc.
Step 3. Take out any expandable memory SD cards etc, from inside the phone
Step 4. Now to perform a factory reset, this will delete everything that’s within the phone, that includes the memory etc, all your videos, pictures, apps, passwords included will be erased.
Go into Settings, tap the backup button and then the Factory Data Reset Button
Step 5. At this point, you might consider over-writing your mobile phone memory with junk data and then performing a second factory reset. It’s entirely up to you how many times you perform this action, two or three times may be considered enough. It just depends how far you want to bury your information.
Step 6. Now some would say this is a bridge too far, but cybercriminals know no bounds. But it’s a good idea to factory reset on your system's settings and makes sure they’re completely wiped as well.
*The exact steps may vary on the version of Android on your mobile phone, some mobiles may use different names for the buttons.
