I can't sign into steam

Electrical parts cleaner on iphone 6S?

My iphone 6S wasn't charging because the port was full of junk so I sprayed the lightning port and 3.5mm aux port out with electrical parts cleaner, not a good idea. I did this with the phone off, dried it off and turned it on and the screen was displaying with funny coloration, see picture. I turned it off an put it in rice

So the question is: is this just moisture or did I do some real damage with the electrical parts cleaner? It evaporates almost immediately so I was thinking moisture shouldn't hang around too long? Anyone have experience with electrical part cleaner (contact cleaner) or know if the phone is savable or not? I currently have it shut off and in rice still Electrical parts cleaner on iphone 6S

Iphone iCloud troubles

Hi, I must be the most uneducated millennial with technology about. :') I was trying messing with my settings (Trying to 'fix' a different problem I had with my phone), logged out of my iCloud, restarted my phone and when I logged back in and started looking through my photos most of them had gone? I don't know how to get them back, I was thinking it was because I hadn't saved them to my iCloud, but I don't know?

Will my iPhone 6 track my steps when on a treadmill accurately?

I use my iPhone 6 to track my daily steps because it's a free feature in the health app. I want to be able to track my steps when on the treadmill, does anyone know if it accurately will count my steps? Also, with that being asked, does it track my steps accurately from my daily routine?

Video taken off of my iPhone X plays back on my MacBook choppy

I started taking some videos on my iPhone X (4k Quality) to throw onto my macbook and edit on Final Cut Pro X.

When i go to playback my video on my macbook the payback is extremly choppy.

So i have a 2011 MacBook Pro. The specs are:

MacBook Pro (15-inch, Early 2011)
Processor: 2 GHz Intel Core i7
Memory: 16 GB 1600 MHz DDR3
raphics: AMD Radeon HD 6490M 256 MB
Intel HD Graphics 3000 512 MB

I transfered the same video to a 2016 Macbook Pro, and to my surprise the playback was smooth. The Macbooks specs are:

MacBook Pro (13-Inch, 2016)
Processor: 2 GHz Intel Core i5
Memory: 8GB 1867 MHz LPDDR3
Graphics: Intel Iris Graphics 540 1536

Not sure if anyone here can help me pinpoint the problem.
