IPhone x or pixel 3 XL?

So i'm debating on what phone to get. What one would be ideal, what one is your favourite and why? (i love taking pics so keep that in mind)

Is there any possible way to bypass the pin and get into snapchats my eyes only?

So i few month ago i changed i changed my pin in my eyes only in snapchat but now i forget it. When i press the "forgot passcode" button it says i can reset my passcode but it will delete all the photos in my eyes only. I have so many great pictures and memories of my friends and family in there that i can't lose. I've contacted snapchat multiple times asking if there's anything they can do but they were really no help. I understand that they are really strict with the my eyes only security. Does anyone know if there's ANY POSSIBLE WAY to get into it without changing my passcode and deleting My pictures? Should i take it to some sort of phone store or something to see if there's something they can do? I'm even willing to learn how to jailbreak my iPhone if anyone knows if that works. Any help is appreciated.

How do I stop iTunes from changing the name of my downloaded files?

I don't know how many people are still using iTunes, but I have files perfectly catalogued by year/month/day, but when I copy it over to iTunes, it only has the program name without the date (the most important part in this instance). When I looked up this problem, everyone said to go to iTunes preferences, advanced settings, and uncheck the keep box. But it didn't change anything. I even quit iTunes and reset my computer, but it didn't fix it. I would rather not have to manually change the names because there are hundreds of them.

How can I clean out my charging port? (iPhone 6s)?

My iPhone 6s was having a hard time charging. I figured out it was the charging port being dirty, but I don't know how to clean it out. I've heard toothpicks work, but I can't find any. Any other way I can clean it? Toothbrush? Cotton swab?

Don't know how to get into iPhone?

My nephew reset his iPhone (i don't know why) he didn't do it correctly though. Instead of logging of his Apple ID and doing erase and reset he only rest it. Now the phone is asking for his Apple ID info to get back in which surprise surprise he doesn't know it. I have no idea why he or his parents didn't god damn save it anywhere. Being as the one who resets the Wi-Fi thus fixing it I'm considered the tech person around lol and have been asked to solve such problem. I have no idea how. Is there anyway I can reset the phone to factory mode where the Apple ID gets erased and I can then create a new one?
