Flash I used to be able to switch the flash settings on the camera, when it's on 'auto adjustment', from on to off or automatic but now its just stuck on off and it doesn't allow me to change the settings. The only choice I have is to attempt using the 'twilight portrait' but I don't get the same effect.

I don't know the Leica camera, but the auto mode means the camera does take care of everything. The only thing you can do is choose the camera, not to use the flash, so it needs to measure and use a higher ISO. But if you want to adjust the flash, see what the camera did choose for shutter speed and aperture. Then put it in manual, choose the same and use your flash to the setting you want. Then adjust your settings. Can be the speed and or aperture, but also the flash to 1/2 1/4 or moe.

Yes. You can use the flash in auto or manual mode by setting the camera to manual shutter speed within the x-sync range and then selecting the aperture prescribed by the flash guide number or the displayed automatic f-stop on the flash. The flash can provide auto exposure with the camera in manual mode, but you need to be aware of the amount of ambient light which will not cause any exposure corrections by the camera in this mode. Another alternative is to select Aperture preferred automatic on the camera and the f-stop shown for the auto flash settings. This will allow the camera to vary the shutter speed but may cause long exposures if the camera is not sensitive to real-time flash readings.

The Nikon Coolpix is a compact digital camera that is well-suited for amateur to semi-professional photographers. Occasionally, some issues with the built-in flash can occur. If the hardware is damaged, the camera must be taken in for repairs. More often, problems occur because of obstructions or issues with the camera's settings and are easily repairable. Follow the troubleshooting guide to fix the built-in flash.

Instructions:
1.Ensure the Nikon Coolpix digital camera battery is fully charged.
2.Wait several seconds before pressing the shutter-release button if the "Flash Ready" indicator light is flashing red. Press the "Flash Mode" button once or twice to change the flash settings from "Off" to "On" or "Auto" if the "Flash Ready" indicator light is off.
3.Ensure there are no obstructions, like your finger or the camera strap, that are preventing the flash from firing if an error message appears on the display screen and the flash is not firing when the flash mode is set to automatic.
4.Press the flash back into the camera after every photo to ensure the flash always fires in "Auto" mode instead of just in low illumination settings. Press the flash back into the camera to turn off the flash in "Manual" mode; otherwise the flash will continually fire.
5.Change the auto focus setting from "Infinity" to "Auto," "Macro Closeup" or "Self-Timer" by pressing the "Focus Mode" button once, twice or three times to automatically turn the flash back on.
6.Use only Nikon external flash accessories to avoid damage to the built-in flash and camera circuits.

I hope you find it very helpful. Thanks.

As long as jog dial is set to M or manual, the flash will not pop up automatically. Be reminded though because you have to set everything manually. If you want the auto settings without the flash, set the jog dial to the icon that looks like a lightning with stop/ no sign

Most cameras have a button that looks like a lightning bolt. Hit that button and it will usually switch between flash options or it will bring up a flash menu. Some camera modes will automatically set your camera to auto flash, so if the room is dark, flash is on, and room is light enough the flash shuts off. You might need to switch to a different picture mode, like P or Programmable that lets you manually set your camera options.

That is correct. Auto mode is exactly what the name says. The camera automatically decides whether to use the flash or not.

If you need to use the flash, switch to one of the non-auto exposure modes, such as P.

If you have the settings on AUTO the camera will automatically adjust to what it thinks will make the best picture.
Try and use the SCN.
You can also switch the flash on and off as you wish.

If successful please give me the feedback as a rating or recommendation. Thank You

The manual says the flash range is 1' to 1.6 feet with setting the ISO speed to auto.

It could be a communication error between the flash and the camera. Check the shoe foot for any damage or stuck pins. All of them must make proper contact with the hot shoe on the camera to get full auto/TTL, same for the shoe of the camera, bent? dirty contacts?
