How do I turn on the flashlight on my iphone 6?

1. Launch the Settings app on your iPhone.
2. Tap on General.
3. Inside the General menu, tap on Accessibility.
4. Scroll down a ways and under the Hearing section, turn the option for LED Flash for Alerts to On.

The flashlight hack that has come to light (pun intended) recently does not include the light that comes with the Iphone.

If you must have a different flashlight than the one that comes with the phone, make sure it a small file. Large files could surely mean it's filled with spyware, tracking your location via GPS.

My advice is just use the flashlight that comes with Iphone. It does the job just fine.

no, android phones had an issue with flashlight apps but apple verifies all apps rigorously first. so no its not true and you should be safe. note that from iOS 7 and up there is a built in flash light app on iPhones

Flashlight for iPhone iPod and iPad

downloads over footage of iPhones
Here's a clip of cybersecurity expert Gary Miliefsky explaining how all of the top ten flashlight apps on the Google Play Store are malware over b-roll footage of iPhone users toggling the flashlight in Control Center. In fairness to the editor who put the package together, there probably isn't a whole lot of file footage of people opening random free flashlight apps on an Android phone.
The actual information in the clip is somewhat amusing (if you're an iPhone owner) or frightening (if you don't pay attention to the Android apps you're downloading). According to Miliefsky, a large number of flashlight apps on the Google Play Store are actually transmitting user data including address book entries and personal information to multiple endpoints in at least three different countries.
Half a billion devices have apparently downloaded the malicious software, which Miliefsky says can only be fully removed via a full factory reset. Whether these app developers are using the data for anything nefarious hasn't been determined but it's best to be on your guard when downloading apps, even from official sources like Google Play. Miliefsky's suggestion is to find a flashlight app with a very small file size since larger apps likely contain a large amount of malicious code, but for advice from a security expert that doesn't seem like a great way to be sure of an app's intentions

Holding the phone vertically, from the main screen, swipe your finger from the bottom button of the phone to the top to show the option menu. Press the icon that looks like a flashlight to toggle from on to off or off to on.

With IOS 7 it is very easy to turn the flashlight ON and OFF.
When you are in the home screen you have to swipe your screen from the bottom towards the top. A menu will appear.
By pressing the flashlight icon you can turn the flashlight ON and OFF. You'll also find shortcuts to the timer, calculator, camera, controls for music and buttons to turn several wireless connections ON and OFF.
I hope this wil solve your problem.

this might not be the problem if you have very low battery power

Swipe your finger up from the bottom and touch the flashlight icon.
