Has my iPhone been hacked?
I have had my iPhone 13 mini for 1 year and 1/2, but ever since I got it I have had issues with it. From the first fortnight it began overheating for no apparent reason and I took it to 2 separate apple stores during that time, who kept it overnight but were unable to fix it. Since then the problems have only gotten weirder. One instance is when I power off my phone. When it turns back on it will go onto the lock screen, only the camera icon goes dull and when I swipe up to use my Face ID the screen immediately goes back onto the black screen with the loading circle for about 5 minutes until it goes completely black and the apple logo appears again. The only thing that fixes this is connecting it to my MacBook, but this continues to happen around every 3 months. Also now I am reaching the end of my storage limit. I am trying to delete storage, but every time I check to see how much storage I have it is nearly the same as before. I deleted over 100 photos at the same time and it added 0.1 MB of used storage! I can’t use most of my apps and it is causing me stress at the thought of losing all of my existing data on my current phone. I work on my phone. I am reluctant to transfer things to another device in case it has been hacked at some point - I know iPhones don’t get hacked, but I don’t know what else this could be. Please help!!!
