As the OP of this topic, I feel the LED brightness is at the bottom of the list of things that need fixing. There are some pretty major functional issues that should be prioritized.

1. Top of your list - instructions are wrong or incomplete.
Has zero to do with the functionality of the camera and a new version can be posted on the Viofo website. Should be the last thing of all complaints.
2. Can't format without the app.
It's a wifi camera. Who is going to buy a wifi camera and then complain you have to use an app to format it? Again has zero to do with functionality of the camera. You can always use a computer to format it.
3. Only 2 android apps and only one works.
This is ridiculous. How many do you need? First you say you should be able to format without the app and then complain there are only 2. What company is going to come out with a product and than make 50 apps that do the same thing for it? Zero to do with functionality.
4. Beeps when not recording. This is an excellent feature. Who is going to drive around with the camera on but not recording? Zero to do with functionality.
5. Setup cannot be done without wifi app.
Again it's a wifi camera. What would you expect? Mobius isn't wifi so that's why you can load options to the card. Waste of program space and developer's time to implement this. Zero to do with functionality of the camera.
6. Red led should flash when recording and not solid.
The Viofo 119A has always had a solid red led for recording and no complaints. The led is to let you know at a glance it is recording. The flashing would be distracting just like the beeping you don't like. Zero affect on functionality.
7. Leds too dim.
If you can't see the leds you can't tell if it is recording. Doesn't matter if it flashes or solid, the leds convey important info. You don't want the beeping when not recording and with unseeable leds you would have no indication of recording, not recording, wifi, or even power. There is no screen so visible leds are a must. This is a vital functionality issue. Can't be fixed by posting on a website or with an app or firmware update. Must be done on the hardware and is the only thing on your list that can't be fixed once you have the camera.
No one complains about anything on your list but the LEDs and that can only be addressed in the hardware so should be the top priority.
