What is this grey screen spreading onto my iPhone in Safari?

I have an iPhone 6S. Today I noticed something weird when I pull up a new Safari page. Instead of the web address screen that shows icons of my most visited web pages, it is just a white screen (with the URL box). Then, when I type in a website, light grey spreads over the screen. Otherwise safari seems to be working ok, but why is this randomly happening? Could it be a virus?

How long will 12GB of data last when ho spotting from an iPhone to a Mac?

I checked my data allowance earlier today to see how much 4G I've used so far this month (today is the 17th July) and with general usage of social media, internet browsing and a couple of YouTube videos most days totalled at a few hours per day as well as the occasional live stream here and there, I've managed to use just 1GB of my data allowance. So my question is if I were to use my phone as a hot spot for my Mac for several hours one evening, just how long would it last assuming I'm doing the same stuff I d be doing on 4G?

Added (1). Just to make it clear, my 4G allowance is unlimited but my hot spotting is limited to 12GB and I meant I was doing all those things combined for a few hours, not a few hours each.

Is there an accessory compatible with current iPhones that will receive FM Radio signals?

I have an iFM Radio Receiver made by Griffin I used to use to listen to the radio on my iPhone since I had an iPhone 4. I eventually purchased a Dock Connector to lightning adapter to continue using the device. However, recently my iPhone told me that the developer of the app (Griffin) would need to update their app to continue using it. So, I contacted Griffin support, who informed me that they had no future plans of updating their.

My question is, is there a more current product I could purchase that receives an FM Radio signal, and has a supported app?
