About this app

Flash Alerts 2 makes your phone's flash (LED) blink for incoming calls, texts, and app notifications - so you never miss an alert in a silent meeting, a loud room, with earbuds in, or if you're deaf or hard of hearing. First released in 2013, Flash Alerts 2 is one of the original flash notification apps for Android.

FEATURES
- Incoming call flash - the flash blinks when your phone rings
- App notification flash - pick which apps (texts, messaging apps, and more) trigger a flash
- VoIP call notifications - flash for incoming voice/video calls from apps (Android 12 and above)
- App Notification Filter - choose exactly which installed apps trigger a flash
- Custom flash pattern - set the on/off length, plus a repeat count for app notifications
- Flash blink mode - Auto (recommended), Standard, or minimize status bar flicker
- Flash position - front, back, or both
- Trigger flash only when the device is locked
- Control flash by device state - ring, vibrate, or silent
- Schedule Do Not Disturb hours when flashing is paused
- Home screen widget to toggle Flash Alerts 2 on/off at a glance
- In-app language selection (20 languages) and light/dark theme

FIRST-TIME SETUP
1. Grant Notification Access - required to detect app notifications. Turn on "Flash Alerts 2" in the settings screen the app shows you.
2. Select apps in the App Notification Filter - you must pick which apps (texts, messaging apps, etc.) should trigger a flash. If no app is selected, app notifications won't flash at all.
3. Exclude from battery optimization - so flashing keeps working reliably when the screen is off.

NOT WORKING?
Most issues come down to one of the three steps above - double-check that you've selected apps in the App Notification Filter. Still stuck? Contact us at support@megawave.app with your device model and we'll help.

Thank you for trusting Flash Alerts 2 since 2013.
LED flash blinks for calls, texts & alerts - handy for deaf users & silent mode.

This app, for the most part, is pretty much useless. I've used it for the last 3 years or so without a problem. However, with the recent changes in Google's policies, the developer has had to remove certain features rendering it useless. I'm giving 5 stars because it "was" an excellent app. It doesn't seem fair to the developers who lose their revenue from future sales and to customers who purchased it with no refund offered from Google.

Hi Team, App is awesome and working fine as expected but the problem is we have to keep open the application in backend. If we will close the application and receiving any call at that time, Flash is not working. Which is a little bit hectic for the user. Please provide the solution.
