I wanted to take photo from rear camera but couldn't. But front camera is working properly

When I try to take photo the phone is lagging. The rear part od phone is heating.the "photo" that I try to take is shown as with an error mark in "albums"

You may need to perform a software repair using PC Companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 60% battery.

Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).

Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).

Before repairing the phone, what if you boot on safe mode and check if you get the same issue
