Hi Tanaka,
Welcome to iFixit. We do indeed have some very smart people here on this site, including Alisha (@flannelist), who is the author of our Kernel Panics wiki page.
[[iPhone Kernel Panics|iPhone Kernel Panics - iFixit]]
On that page there is a section titled ANS2 Recoverable Panic that describes exactly what's going on with your phone. Here's the relevant section.
[quote|format=featured]=== ***ANS2 Recoverable Panic*** ===
ANS2 (Apple NAND Storage version 2) is Apple’s controller for, you guessed it, storage. NAND is a type of flash memory commonly used in modern smartphones and computers with soldered on storage.
* If you get this panic, chances are the chip which houses all the data on your phone is malfunctioning or communication lines to the NAND are not functioning properly.
* Replacing the NAND requires microsoldering skills and the use of a programmer to write unique data from the old NAND chip to the new one.[/quote]
Unfortunately, fixing this issue requires skills and equipment far greater than most of us have. In other words, it may be fixable, but would require the services of an expert repair shop who can do board level repairs.
I don't suppose your phone is still under warranty is it? If not you may want to consider whether it is going to be worth the cost of repair versus simply replacing the phone, I'm sorry to say.
