Today Iam share my personal experiance about Iphone 4s. I was bought this phone in 2016.
After using one month this mobile is suddenly hang and after few minute this mobile is restart automatically.
And if we use this mobile 2 hars continuously then this mobile is more heated automatically.
Some application are working ios 10 and upper level version. But this mobile is not update after ios 9.3.5 version This is verry big issue in this mobile. And this mobile is not support 4G network.
