Does airplane mode on iPhone 4 messes up your App Store connection?

I can't think of anything else to have messed my App Store on my phone… Every time I try to install something on my phone from the store it said " can't connect to iTunes " or something like that… I don't know why it's not working 'cause my Wi-Fi is working perfectly fine

Just turn it off and back on, never heard of that happening…

  • Why does my iPhone act weird when I turn airplane mode off? I use airplane mode all the time (To kill dangerous radiation), but when I'm home alone and my parents need to reach me, I shut it off. My phone sometimes starts acting weird when I do that. It's an iPhone 6s, and about 1 year old. Is it the airplane mode, or is it the sudden radiation messing with the technology? (Parts of my body sometimes start randomly hurting too - Adds to the fact that radiation in our daily life is not good at all.
