To turn on Safe Mode, follow these steps:
1. Power the phone off.
2. Once the phone is off and all lights are emitting, press and hold the Power button to turn the S4 back on.
3. When the Galaxy S4 logo appears on the screen, press and hold the Volume Down button.
4. Continue to hold the Volume Down button until the phone completely boots. You will see the words "Safe Mode" appear in the lower left corner of the screen if you performed the steps properly.
While in Safe Mode, you may not be able to use certain features or applications. The device is in a "bare bones" state where just the essential software is loaded. This allows you to get into the device quickly, enable or disable whatever you need to, then restart.
To turn off Safe Mode, powering down, then back on should do the trick. Be sure to power completely down. Do not select "Restart". If you still have problems, remove the back cover and pull the battery from the device. Leave the battery out for about 60 seconds, then place the battery back in, assemble the rear cover and start the phone again.
Some Galaxy S4 models may require you to press and hold the Volume Down button during startup in the same manner as enabling it to exit Safe Mode.
That's all there is to it.

Auto Shutdown Samsung GALAXY S4


Did it start over or just died for you? I noticed that my S4 was starting over all the time although it was in my pocket and I didn't touch it. But I figured that I have some option to automatically download updates, and when it does, it restarts itself. Hope this may be a help for you?

Why does so much heat enter my 2004 audi s4 from the transmission tunnel?


Hello,

the cause is the exhaust system and the two-way catalystic converter system of your S4.

The converters become very hot if you put the hammer down (app. 500 deg. celsius on the outside) and even though there are heatshields mounted between the converters and the vehicle´s floor, you can feel the heat inside.

The transmission itself is producing high temperatures as well, so no worries, remember your S4 is sport´s car ;)
