Hello, Just following up to see if you still need any assistance?
My phone is S5 and it to appeared a few days ago. I actually went into the flashlight setting and disabled the on/off feature and it worked.
Thanks for the post. It really helped.
I've had issues even after disabling it. I've had my battery drain from 40%... 38...34...27...22...15...9...etc all within a few seconds. Several times now over the past week or two I'll get a notice that my battery is at 15% and then about 2 mins later on standby, it dies completely and shuts off. Extremely annoying and I can't seem to fix it. Finally deleted the flashlight app today after finding this thread and hopefully my battery situation improves.
