Will a new LCD Screen be enough to fix my phone?

I have an iPhone 6s. I dropped it the other night and it was still playing music just the screen went black. I turned off the phone and ordered a new Screen replacement.

Now because the phone was still working after the screen went black, does that mean when i change the screen will everything work as it did before?

How do you prevent image compression when saving pictures to iPhones?

So, I'm a digital artist and I find that the filters found on iPhones are very nice for color correction or just to make the thing look prettier, because my monitor has a problem of displaying everything too blue (so the actual image turns out to be super saturated and pink/yellow). However, so much of the image quality is lost when I save the pictures to my iPhone (I usually email the pictures to myself). This is a problem, because I love the effect the filters give me, but I can't use those final images for prints because the resolution is so small. Is there a solution around this?

My iPhone notes just VANISHED! - 1

Today, I was in the middle of a note on my iPhone. While writing it, my phone froze. This has happened before so I just let it tire itself out. I exited the app, came back, and no lie, EVERY SINGLE NOTE WAS GONE! I don't know how it happened! I keep some of my most valued pieces of writing there and I honestly couldn't live without the app… Can someone Please explain to me how it happened and what I should do?

Si tengo una cuenta diferente para el App Store en mi iPhone?

Si tengo una cuenta diferente para el App Store,

My phone is acting weird?

I have an iPhone 6s Gold, and it's been acting very strange lately. Yesterday it froze and I had to force restart it, and about 20 minutes ago I was using an app and my phone acted like it was shutting off but then it stopped and went to my lock screen; this lasted for literally only about 5 seconds. I'm very behind on my updates as I haven't updated it since iOS 10 I think (the update that completely changed the layout of the phone). How much longer does it have?

Iphones been charging for 3+ hours and still isn't turning on

My iphone 6 has been having terrible battery issues lately but sadly i can't afford to replace the battery right now so i've been dealing with it. However, my phone just died three or so hours ago and still isn't turning on! This is kinda URGENT, because it's finals week for me at school and i really need my phone tomorrow to be picked up early as i have an empty block. I'm desperate! I've tried hard reset (left home and power button down for about 1 minute and still nothing happened). The Charging icon thing is showing up but it's not turning on.
