How about this: also unlocking the phone with the gloves not always works, sometimes I need to press the home button 5-10 times to see passcode screen for crying out loud...Both our 32gb SEs are working perfectly on the latest IOS 11 version. As smooth as ever.
I don't know what most of the other contributors to this thread are complaining about.
Battery life is excellent with both phones having about 50% left at the end of the day but this usage is highly dependant on personal utilisation of the phone.
There must be thousands of people out there who are quite happy with their phones and don't feel the need to agonise on here about "faults" that are barely noticeable to the rest of us.
Tha range of "faults" reported after each upgrade are all depressingly similar and yet life goes on and the phones continue to provide the same service they have always done for the vast majority.
To most people their phones are not a hobby but a tool to facilitate their lives. Long may it remain so.
