I need some help from S4 users.

My old Samsung Galaxy S+ have this feature where my iPhone 5 and previous Sony Xperia Mini Pro don't have, which is the photo taken by the phone have the date and time as the filename:



As you can see from the example above the date and time is the default filename set by my Samsung's phone, a feature that I depended heavily on my work.


Does the S4 photo's filename is like this too? I plan to upgrade the phone but it must have this simple feature.

Hi, can anyone tell me about the recommended charging practice for this phone?
I'm gonna get this phone today as company phone.

I know for my iPhone they recommend to fully discharge and recharge once a month, my Galaxy S+ need to recalibrate the battery counter chip every year like that. Just want to know about this S4.
