A factory reset makes your device just like it was when you first took it out of the box brand new. It is done from with in the Android OS it self via Settings/SD & phone storage/Factory data reset. Any apps you have installed, your contacts, bookmarks, any personal settings you have will be removed. If you go into Settings/Privacy and check backup settings your settings will be backed up to google. It is also a has a Automatic restore option there that will automatically restore your settings for you if you have backup settings checked.
A hard reset does the same thing a factory data reset does, but you have to use the external buttons to do it. Each device has it's on combination of buttons to preform a hard reset. Some devices have it as a option in the Hboot/Recovery screen. Some say a hard reset does a little bit more thorough or deeper cleaning, but I have found no one that can answer this for 100% positive.
you can also preform a factory reset using Clockwork Mod Recovery by choosing the factory data reset option in the main menu of Clockwork Mod Recovery.
As for it solving your issue with lagging. I can not say proof positive it will as I do not have a device like yours and do not exactly what is causing the device to lag. But a factory reset has been know to help solve a lot of issues, one is laggyness. I suggest you do it as it is no risk involved in doing it. Plus with Android it is easy to restore your device to the way you had it. The market keeps track of the apps you had and you just open the market, press yhe menu button and then my apps. this will let you get your apps back.

[Q] Fingerprint not Recognised after Restore

Hey guys, I just did a factory reset because I was told that it may help with some battery issues. I did a backup in CWM and also one through Titanium. I wanted to use Titanium to restore but it kept hanging so I did a restore through CWM instead. Everything seems fine except that it can't seem to recognise my fingerprint anymore. I can still unlock the lockscreen with my backup password. However, when I try to use the backup password to edit my fingerprint in the settings, it says that my backup password is invalid! How can that be when I JUST used it to unlock the screen? Any advice would be much appreciated.
By the way, if it's true that a factory reset might help with the battery life, would restoring from CWM make any difference or did it just return it to its previous state?
For a while ago i did restore too and fingerprint did not work. As i know the restore whipes fingerprint data. So only solution is to flash whole rom angain or do factory reset and start at the begining.
As i heard, the factory reset might help with battery life. But if you do a reset, then your fingerprint broblem is solved.

Recover pictures after factory reset

Yes I know this is a stupid thing to do but the factory reset has lost all my pictures. I have tried to go down the root of Rooting the device and then running some recovery software but not very successful hence my other thread of restoring. Is there any easier way to get the pictures restored after factory reset ?:cyclops:
The internal storage is encrypted by default anyways, there's absolutely no way to recover anything from it after a factory reset.

Factory Root Reset - Data still recoverable?

Hello,
I have around 2 years ago made a factory reset on my phone plus a root upgrade. The reset was not a typical factory reset but really a factory reset made with the root tool.
There was also a warning that all data will be erased. Now I want to know out of curiousity if there's any way to recover data of that phone via a tool or device.
I'm only curious as it might have old photos and files I have not backed up - nothing important tho.
It's a Sony Xperia Z3. Thanks
