New iPhone hacked
I've always been an Apple fan, and since iPhone 4 I have been buying apple products, including laptops, iPads, iPhones etc and have been absolutely loving them. And neither do I know that hacking is possible on those devices because IOS is known to be secure.
At the beginning of this year I have been targeted by someone on the internet. And it was from that point I learnt everything about hacking. At the beginning I did not know my phones were hacked and it looked very normal. I was browsing through Twitter/X, Instagram, discord etc on a daily basis, without noticing anything strange. It was later in the year (around May and June), whenever I make a video call with my mom, and when we mention sensitive information, my phone started flashing black screen. My phone also started to get slow/laggy at times and occasionally overheat (even when I was doing nothing on the phone). My phone's cellular signal also started getting poor. Like I can stay in the same spot (which has always been full bar signal), it will become 2 bars and then back to 5 bars (very very strange), because to my knowledge phone signal does not change very often especially if you stay in the same area same spot. It was from that point I suspected my device was comprised and my phone screen was monitored.
I am looking for resolutions or suggestions on this issue but personally I am giving it very little hope.
iPhone 12 Pro, iOS 17
