Hi everyone,

 

Random question I know, but - is a 'Factory reset' the same as a system uninstall/reinstall? 

 

If not, how would you go about absolutely wiping a mobile phone clean so that no files from the previous set-up were left? As in, nothing - no history, no pictures, cookies, nothing?

 

Thanks - much appreciated!

A factory reset is basically resetting your phone to how you bought it, as in never been used or touched

I am slightly concerned as I heard that Android phones' Factory Reset option doesn't actually fully delete data.

 

http://www.techtimes.com/articles/55837/20150527/androids-factory-reset-does-not-wipe-your-data-heres-the-solution.htm

 

Is there a way to work around this?

I want to 100% delete any file, history, or any trace of my personal information on there.

 

Thanks for the help!

Bit overkill IMO, why would you need to do that, but then again none of my business

<snip> how would you go about absolutely wiping a mobile phone clean so that no files from the previous set-up were left? As in, nothing - no history, no pictures, cookies, nothing?
<snip>


see here:What to do before giving away or selling your Android phone or tablet

The key take away from the link is this:
 

Once you're absolutely, positively, 100% sure you have everything you need backed up, you can wipe your device squeaky clean. There are a couple ways to do this. You can boot into recovery and use the factory reset/wipe data command, or go the more user-friendly route and go to Settings > Backup & reset > Factory data reset (if you don't have menu options exactly like this, you should have something very similar). This will erase everything on your device. If you're presented with checkboxes asking if you want to wipe external or internal storage, be sure to check these too.

When the device restarts, it should boot into some kind of welcome screen -- just like when it was booted up out of the box. After the reset, you can reboot to check and make sure everything is gone, if you so choose. If you're leaving an SD card in the device for the next owner, be sure to delete all its contents too. A factory reset does not always wipe removable SD cards.

I see - thanks.

 

You said " There are a couple ways to do this. You can boot into recovery and use the factory reset/wipe data command, or go the more user-friendly route and go to Settings > Backup & reset > Factory data reset " - are these both exactly the same option, except one is more user-friendly? If not, how do I boot into recovery mode?

 

Thanks!

Booting into recovery mode generally involves your hardware keys. It would likely depend on the make and model of the device. Google "boot into recovery mode for 'insert make and model of device'". That should return results of how to boot to recovery mode for your particular device.

OK, thanks.

 

Two questions:

 

1) Is booting/recovery mode more effective than the user-friendly option? 

 

2)... My main concern here is that I think I might have got a virus on the phone. I'm 99% sure I haven't, but since I hardly use the damn thing I was wondering about the factory reset so that on the off chance I do have one, I could protect my personal info by...well, destroying any files with them on (I have back ups). 

 

So - if I do a factory reset, would that definitely kill the virus IF it is on there?

Since I've never had the opportunity to ever reset a device in the 6+ years of Android use. I don't have a verified opinion of what the best reset option is.

Maybe someone else with real world experience will be able to chime in here.

Likewise, I'd appreciate any input from someone who has experience of these things.

 

Thanks...!
