iPhone 5s bootloop
What is causing my phone to bootloop ? Every since I updated from iOS 10 to iOS 11 my phone randomly shuts down and tries to reboot, sometimes as many as 20 times. Never had this issue until I updated to iOS 11.2. Chatted with Apple support and tried every trick they recommended but nothing works. I hear Apple is intentionally screwing with software on older phones so everyone will buy new models. IS THIS TRUE? Someone please help!!
iPhone 5s, iOS 11.2.6
