Things you can't access while in "Safe Mode" should still be there once you are out of it. Unless of course you delete them.
If it is just in "Safe Mode" with no added hardware issues, I suggest you try the info below to get out of it. However, if it is stuck due to say a damaged or stuck button, then you have to get that fixed first.
To get out of Safe Mode, please try the following.
1. Touch and Hold the "Power" key.
2. Tap "Power Off".
3. Once the phone is off, Touch and Hold the "Power" key again to restart.
The phone should now be out of "Safe Mode".
If the "Safe Mode" is still running after you restart your phone, I would then check to make sure your "Volume Down" button is not stuck. Check to see if it has anything stuck...
