The number of folk that have this phone, need that flash is too much a niche product. Look at camera owners and how many use a remote flash. You are talking about a very small percentage.
I strongly suggest you sell your idea and take your money off to your next bigger idea.
Hi, guys. This post isn't an advertisement or spam. I really want to hear some feedback about our invention. It's a first LED Flash for smartphones and tablets. Portable, powerful, easy-to-use flash which can be controlled from any mobile device using 3.5 mm audio jack.
What do you think about such device? Do you really need a powerful flash for your camera phone? How much will you pay for external flash?
We are planning to launch our device at kickstarter soon and its really important to hear your feedback!
Hope thread's moderator will allow to post a few photos of device and test pictures
