A hacked Iphone 6?
I have an iphone 6, running on the latest OS system. Recently ive been having suspicions that it is hacked, because my windows computer was hacked last month. The hacker even attempted to get remote access, and accessed my email ids. Ive since changed my email id's, bought a new laptop. Didnt notice any unusual activity after that. BUT, recently i started wondering if the hacker has gotten access to my iphone. For your info,my phone is not jailbroken. I didn't really notice any apps i didnt open being opened, no usual signs of weird messages being sent. I reset my phone just in case 2 weeks ago, and did it again yesterday. Full factory reset.
Last night i was trying to turn off background app refresh for instagram, and it kept turning on by itself, immediately. Like i would turn it off, if i went back to settings, clicked on instagram again, 1 second later. It would be on. This happened about 10-12 times until it finallystopped, and remained turned off after that.
Is this a bug anyone else is facing? Has anyone else on this forum had experience with a hacked iphone? Can an iphone 6 be hacked?
I would really appreciate some answers that explains my problem, not just say that an iphone cannot be hacked.
iPhone 6, iOS 8.3
