Dear All, I was wandering if I am the only having the following problems after upgrade to iOS9 on iPhone 4S: - Personal hotspot not working anymore (I can see it in setting I can switch it on, but cannot connect any of my devices, and I mean: MacBook Pro 13", Lenovo X200T, LG G2 Mini, iPad Mini). I did not have any problems on iOS 8.4 - Sometimes (it happens 1-2 times per day) when I click on the phone icon it just stuck and I cannot do anything, cannot dial a number, nothing, I need to switch off/on the phone in order to be able to dial a number. I already tried to: - switch off/on the phone - reboot the phone - restore the phone Unfortunately still having the same problems. The only plus was that I have more free space on my iPhone after the restore... Thank you in advance for your reply, comment or feedback.
