Hi, yesterday my Blackberry started doing something weird.
After I get an email or text, or anything, the red light on my phone starts blinking much quicker than normal, and keeps blinking even after I check the message.
I can turn it off by activating an app called front flashlight that uses that light as a flashlight, but otherwise have been unable to fix the issue.

Sounds to me like a problem app, perhaps the very one you mention. Delete that app and see what happens.

youv got an app that trigers your light and people think its a cool app so they download it if you dont like it just go to your apps and deleate that particalar app .
