Exactly a week ago Apple released iOS 10.3 for the iPhone, iPad, and iPod touch. Today it has released the first patch in the form of the 10.3.1 update.
This is primarily a security fix related to the Wi-FI, where an attacker within range may be able to execute arbitrary code on the Wi-Fi chip. The issue has now been fixed.
Another fix in this update is with regards to the older 32-bit devices that are still compatible with iOS 10, namely the iPhone 5, iPhone 5c and the iPad 4th generation. These were unable to download the 10.3 update over the air when it released last week and you would have to use iTunes. With 10.3.1 these devices can now download the update over the air again.
This Update has not fixed the battery drain issue on the iphone 5s. Anyone know when Apple intends fixing this issue?
Myself update the 10.3.1 but I facing mobile heating always and also battery drain fastly
That's a great joke!
