I have the iphone17 (standard not pro) which I purchased 2 weeks ago and have had multiple software issues, specifically in relation to downloaded apps. The issues came only a day or two after app installations of Instagram and YouTube. This is a brand new iPhone 17 not refurbished or previously owned, I opted for the transfer iCloud data while setting up my phone. While watching YouTube videos in full screen, while swiping from the bottom corner out to exit the YouTube video, on multiple occasions it caused my phone to completely shut off, turn black, and restart on its own. As for Instagram, when viewing reels, multiple reels will appear distorted either by the video being flipped upside down or showing a horizontal split screen mirroring of the video and flashing. I scrolled pas a couple reels to make sure it wasn't an effect. Notably, I know it was not a video affect that the creator themselves implemented because while scrolling to check if other videos were doing it, I reached an ad and the video right after it had the same effect but, I reversed back and scrolled back to the previous ad that was initially displaying normal and now was displaying the mirrored flashing effect. Further for Instagram, opening links from iMessage have been reading incorrectly, the first link I opened from iMessage to Instagram shows me the reel the correct reel i had been sent although, when trying to open a second real link from the same iMessage texts the link in accurately brings me back to the first video instead of the link that I pressed. Lastly, (this happened today) I noticed that in one of my apps that requires a security code it was holding down the number two on its own disabling me to correctly enter my pin. Most of these issues temporarily fix on their own when I close and reopen the application but they do arise again, especially Instagram reels. All of my apps are updated. I have automatic updates on and I did manually go into the App Store and press update on all of my apps. And yes, my iOS is up-to-date (26.3.1). I don’t know if this makes a difference, but I do not have Apple Intelligence turned on.
