Can't delete photos from iPhone?

I just upgraded from a 5 to a 6s, and synced all my data to my macbook and then to my new phone. There was a duplicate of nearly every photo.

Iphone 6, apps taking FOREVER to download?

My Wi-Fi is fine, but for some reason downloading apps takes forever! This hadn't happened before to me. Downloading a simple game like agar.io would usually take less than a minute, but now it's taking over 20! This is happening on both Wi-Fi and LTE, and I can't seem to fix it. I've tried restarting my phone and resetting the network settings, but it didn't do anything.

Overly bright LCD screen on iPhone 5?

Why is my LCD screen so bright? I can see it very clearly-- except for the edges, it slowly goes into overdrive until it becomes way too bright & makes the screen look fadey and too white. This phone has been around for a while and was a hand-me-down from my mom-- is it time to replace the screen?

Added (1). There was not water damage except for a bit of rain on it, which I immediately wiped off as best I could.

Bad quality when uploading to Instagram?

I have a iPhone 6 Plus, prior to uploading to Instagram the quality is great but when I upload it, it just gets really bad. Today I decided maybe if I change the settings on my camera to record at 60 FPS it'd be a lot better quality on Instagram, well I was so wrong, it literally got worse when I uploaded it. Is there a way to fix this because it's the most annoying thing in the world. I have great Wi-Fi and my cellular data is LTE with Verizon so it's pretty good as well.

Why can't i remove these songs from my iphone?

I purchased then a long time ago but i really hate seeing them on my iphone now because they waste space. I can't remove them and i've tried turning off icloud, i've deleted them off my itunes library, off my playlists and the only place i can see them is when i plug in my phone to the computer and click on "my iphone". Each time my phone syncs, they get put on my phone again after i've deleted them physically off my phone, does anyone know how to stop these specific songs from getting put onto my phone every time without deleting all my other purchases too?

How to get the restrictions passcode off of my iPhone 4?

My dad set a password for my iphone a few years ago for the restrictions, and I have since gotten a new phone, but I don't really want to get rid of the phone and want to use it for personal use. I have an IPhone 4 with 7.1.2, and just want to unlock all of the restrictions. He used his apple ID, so I can't turn off Find My IPhone to restore a Really old backup without the restrictions.

Added (1). He doesn't want to give it to me, so he says, meaning he forgot and doesn't care.

Is an Iphone really bad to record your singing?

Is an Iphone really bad to record your singing? - 1

Added (1). I've heard from other people that they sound bad on it. Well I know they don't have surround sound or have a program like Audicity in it.

But when I recorded mine I sounded fine and even had a person listen to it, response was Positive. Is it surprising for a person with 2 1/2 Years of singing to master singing on a Simple device. I'm a Tenor btw with a Bass/Baritone talking voice.
I just wanted to know if Iphones have bad microphones.
