iOS 7.1 update bring carrier unstable "Searching..."
Hi,
After upgrade iPhone 5 to iOS 7.1 my carrier signal becomes unstable after every 30 sec it starts to searching it. Battery also affected as I am not able to use it for more than 6 hours. Before it was fine on 7.0.4 but later without upgrade my signal becomes unstable yes without upgrade my signal becomes unstable. then I thought to upgrade it so it will resolves the issue, but who knows the situation got worsed. My battery drains from 100% to 10% in 6 hours (maximum). My carrier signal is fluctuating in one minute it changes it three states
1. Searching
2. No service
3. Vodafone IN ( means it got signal full 5 star )
4. but soon after 10 sec again gone
Please do a fix for this as I am not able to use my phone it is lying in my drawer.
iPhone 5, iOS 7.1
