We keep a running note of where flashlight testers give up. It is almost never on the main button. The main button is large, it is in the middle, and it does what a torch is supposed to do. The giving-up happens when the task is “make it blink” or “stop it from blinking.”
In five of the last six flashlight studies in Petaling Jaya, the strobe control lived behind a gear mark, then a row labelled More, then a toggle whose name was SOS, Strobe, or Flash. Testers who had never opened that path treated the main button as the entire product. They long-pressed it. They swiped it. They looked on the lock screen. They did not open the gear.
When we asked, after the session, whether they had noticed the gear, most said yes. They had seen it. They had decided it was for brightness of the bulb or for an advertisement they did not want. A gear, in a utility that looks like a single switch, reads as maintenance, not as a second mode.
The testers who did reach the strobe often could not turn it off without killing the app. The toggle to start the blink was not the same control that stopped it. One build used a confirmation on the way in and none on the way out. Another required a return to the home screen before the blink would cease.
If you publish a flashlight, sit with this for a moment: the people who want a strobe are a minority, but the people who accidentally start one are not. The reverse path needs to be as obvious as the main button, or the strobe should not be three taps away from a mark nobody trusts.
