IPhone 6s display not crisp?

Finally did the upgrade from iPhone 5 to iPhone 6s today. All is great except I have noticed that for some reason, the screen on my 6s seems to display pictures (like on Instagram for example) slightly more blurry and pixelated than on my iPhone 5, which is weird because you'd obviously think it'd be the other way around. Not talking about pictures taken with the camera, I'm talking about the actual display performance when I'm viewing a web page or anything with images. The text displays fine as far as I know though. Anyone know anything about the display specs of this phone and why I could be experiencing this? I definitely am noticing quite a difference between the two.

My iPhone video recordings have very low sound, can't turn it up

My iPhone 5s records videos with extremely low sound. I'm not able to turn up the volume at all, and I've tried to reset everything and it wouldn t work. On any other app that uses sound recording, like Snapchat, it's loud and works fine. I can hear music, watch movies, etc perfectly its ONLY this app. Can anyone help please?

I want to get rid of my tinnitus It is interfearing with my life making me depressed! How can I do this?

Everybody is telling me it'll go on it's own! I've have it for almost a month now and the dr said it should go away within a month and it's still there! It came from playing loud music from my Iphone speaker for only a short time and since then there has been gradual ringing that seems to be getting better but jst recuses to go completely!
Are you sure there's no cure for it? It sure is making me feel depresses and interfering with my life, it has even given me a cold as my amune system is low because of it! Everyonr seems to piss me off easily as well! They must know I'm i'm destress! Sometimes I feel it'll one day kill me as if it is dangerous! Is there anything I can do?

Instagram: sorry request has failed?

My IPhone 7 has been acting up lately, the Wi-Fi connection is weak and lots of apps are not working due to the poor connection. Yesterday I logged out of my main account on Instagram and when I tried logging back in it says "sorry, there was a problem with your request"? I've tried restarting my phone, deleting the app and contacting Instagram but all has failed. I don't know if it's either my phone or just Instagram acting up.
