Android 智能手机(Android smartphone)上的相机闪光灯也可用作您几乎总是随身携带的手电筒。但是，为了持续打开它，您需要使用一个手电筒应用程序来告诉闪光灯保持打开状态。
虽然现在几乎所有的Android手机都有内置的软件切换功能来执行此操作，但仍有一些第三方手电筒应用程序存在。我们收集了一些最好的手电筒应用程序，它们不会要求超出应有的权限。
为什么今天有人想要手电筒应用程序(Flashlight App Today)？
如前所述，您的手机可能已经具有软件手电筒切换功能。电话制造商很快意识到这是一个有用的功能，所以他们开箱即用。那么为什么会有人想要下载另一个应用程序来实现相同的目标呢？
确实，大多数人可能不会发现专用应用程序有用，但一些手电筒应用程序确实提供了附加功能。例如，有些可能会提供频闪模式或让您调整灯光的亮度。所以在某些情况下，有正当理由想要一个！
为什么应用程序权限很重要？
最大的问题是，诸如手电筒应用程序之类的小而多的应用程序通常可以简单地成为本质上是间谍软件(spyware)或恶意软件的幌子。例如，您可能会下载一个运行良好的手电筒应用程序，但随后请求管理您的电话或查看您的联系人的权限。显然，手电筒应用程序没有实际理由需要这些功能，因此最好避免使用它们。
对于我们在这里选择的应用程序，通常有两种类型的权限是可以接受的。首先(First)，该应用程序需要访问相机(camera)的权限。其次，广告支持的应用程序可能会要求访问互联网。
在这两种情况下，我们都强烈建议您选择最新版本的Android提供的(Android)Only allow while in use选项。这样您就知道该应用程序没有使用其相机权限在后台记录您！
如果给定应用程序的任何特殊功能需要其他权限，它们也是可接受的。
这个应用程序背后的概念非常简单。打开手电筒所需要做的就是摇晃手机。这听起来可能并不重要，但即使从锁定的手机快速访问菜单，也可能需要一段时间才能找到软件切换。
使用此应用程序，您只需摇晃手机一两次，灯就会亮起。如果灯熄灭并且您只想快速拥有手电筒，则非常方便。
我们不得不将震动灵敏度调高一点，因为它需要太多震动才能激活，但是一旦为我们的手机拨入它就可以很好地工作。小心不要把它调得太大，否则当你走在街上时，你可怜的手电筒会在你的口袋里放一个狂欢！
我们被要求的唯一许可是相机访问权限，并且广告不引人注目。所以这是一个容易推荐的应用程序。
彩色手电筒(Color Flashlight)（免费带广告）
这是一个手电筒应用程序，已经存在了很长时间，下载量接近 50 万次，所以你知道他们一定做对了。
它的主要技巧是它不仅仅是使用相机的LED闪光灯来发光。您还可以控制手机屏幕并使用该应用程序将其强制设置为最大亮度。
您还可以对屏幕的颜色和强度进行细粒度控制。彩色手电筒(Color Flashlight)还提供了一些有趣的功能，例如闪烁的频闪屏幕或蜡烛燃烧的视频剪辑。
它只需要相机和互联网权限，并且在您需要特定照明条件时可以非常灵活。例如，您可以将其设置为低强度的暖色以进行阅读。
图标火炬(Icon Torch)（可选捐赠(Donation)免费）
Icon Torch正如其名称所描述的那样。当您点击手电筒应用程序图标时，什么都不会打开。只有一件事发生：LED闪光灯亮起。就是这样。
这很简单但很棒，因为这意味着您可以将应用程序图标放在最容易到达的地方，例如手机的底座上。这通常比向下滑动快速访问阴影并寻找手电筒按钮要快得多。
这个应用程序不需要任何权限，没有广告（或相关的界面）并且是完全免费的。该应用程序的付费版本为 1.49 美元，价格相同，但给了开发人员Aleksandr Balaev一个小费。在撰写本文时，只有少数人这样做，包括我们。因此，如果您喜欢这款智能且不显眼的应用程序，何不表示赞赏呢？
小手电筒(Tiny Flashlight)（带广告免费）
Nikolay Ananiev广受欢迎的(Nikolay Ananiev)Tiny Flashlight的主要价值主张曾经是其较小的安装尺寸。然而，如今手机拥有如此多的板载存储空间(onboard storage)，以至于没人真正关心。然而，已经有超过 400 万人下载了这个应用程序。为什么？这个手电筒应用程序有两个很酷的方面。
首先(First)，它是模块化的。您可以下载添加您想要的功能的插件，而不会将应用程序与您不想要的功能混为一谈。其次，它解决了手电筒应用的最大问题之一。也就是说，他们完全是耗电大户。
虽然我们不得不相信 Nikolay 的话，但Tiny Flashlight的设计目的是在一定程度上降低总功耗。在紧急情况下，这(Which)可能是真正的救星。
手电筒免费(Flashlight Free)（免费无广告）
此列表中的最后一个应用程序可能是手电筒应用程序的最完美体现，它不会要求超出应有的权限。手电筒(Flashlight)免费是一个基本的、透明的和简单易用的应用程序。开发人员希望解决过去手电筒应用程序引起的隐私问题。
他们小心地解释每个功能的确切作用，每次更新中的确切变化以及用户应该知道的任何其他内容。没什么好说的了，太好了。
现在我们看到了光！
这些出色的手电筒应用清楚地表明，在这类软件方面仍有很大的创新空间。手机制造商仍然可以让我们更快、更方便地激活内置手电筒功能。然而，大多数情况下，这些只是一组很棒的手电筒应用程序，可以点亮你的生活。
5 Best Flashlight Apps for Android That Are Safe
The camera flash on your Android smartphone is also useful as a flashlight that you almost always have with you. However, in order to turn it on continuously, you need to use a flashlight app that tells the flash to stay on.
While almost all Android phones now have a built-in software toggle to do this, there are still a few third-party flashlight apps out there. We’ve rounded up some of the best flashlight apps that don’t ask for more permissions than they should.
Why Would Anyone Want a Flashlight App Today?
As mentioned, your phone probably already has a software flashlight toggle. Phone makers quickly realized that this was a useful feature to include, so they’ve put it there right out of the box. So why would anyone want to download yet another app to achieve the same goal?
It’s true that most people probably wouldn’t find a dedicated app useful, but some flashlight apps do offer additional features. For example, some may offer strobe flashing modes or let you tweak the brightness of the light. So in some cases there are legitimate reasons to want one!
Why App Permissions Matter?
The big problem is that small and numerous apps such as flashlight apps can often simply be a front for what is essentially spyware or malware. For example, you may download a flashlight app that works just fine, but then asks for permission to manage your calls or look through your contacts. Clearly there’s no actual reason for a flashlight app to want those powers, so it’s best to avoid them.
For the apps we’ve chosen here, there are generally two types of permissions that are acceptable. First of all, the app needs permission to access the camera. Secondly, ad-supported applications may ask for internet access.
In both cases we do urge you to choose the Only allow while in use option offered by recent versions of Android. This way you know the app isn’t using its camera permissions to record you in the background!
Other permissions are also acceptable if they are needed for any special features of a given application.
The concept behind this app is very simple. All you have to do to turn on the flashlight is shake your phone. This may not sound like something important, but even with quick menu access from a locked phone it can take a while to find the software toggle.
With this application, all you have to do is shake the phone once or twice and the light will turn on. Very handy if the lights go out and you just want to quickly have a flashlight.
We had to turn the shake sensitivity up a little because it took too much shaking for it to activate, but once it was dialed in for our handset it worked very well. Just be careful not to crank it up too much, or your poor flashlight will be holding a rave in your pocket as you walk down the street!
The only permission we were asked for was camera access, and the advertising is unobtrusive. So this is an easy app to recommend.
This is a flashlight app that’s been around for a long time and has almost half a million downloads, so you know they must be doing something right.
Its main trick is that it’s not just about using your camera’s LED flash to make light. You can also take control of your phone’s screen and force it into maximum brightness with the app.
You also have fine-grained control over the color and intensity of the screen. Color Flashlight also offers a few fun features, such as a flashing strobe screen or a video clip of a candle burning.
It only needs camera and internet permissions and can be quite versatile when you need specific lighting conditions. For example, you can set it to a warm color with low intensity for reading.
Icon Torch is as its name describes. When you tap the flashlight app icon, nothing opens. Only one thing happens: the LED flash comes on. That’s it.
This is simple but brilliant, since it means you can put the app icon wherever it’s easiest to reach, such as on your phone’s dock. This is usually much faster than swiping the quick access shade down and looking for the flashlight button.
This app asks for no permissions, has no ads (or interface for that matter) and is completely free. There’s a paid version of the app for $1.49 which is the same, but gives the developer Aleksandr Balaev a tip. At the time of writing only a few people had done so, including us. So if you like this smart and unobtrusive application, why not show some appreciation?
The main value proposition of the massively popular Tiny Flashlight by Nikolay Ananiev used to be its small install size. However these days phones have so much onboard storage that no one really cares. Yet more than four million people have downloaded this app. Why? There are two cool aspects to this flashlight app.
First of all, it’s modular. You can download plugins that add functions you want without cluttering the application with ones you don’t. Secondly, it addresses one of the biggest issues with flashlight applications. That is, the fact that they’re utter battery hogs.
While we have to take Nikolay’s word for it, Tiny Flashlight has been written to cut down on the total power consumption somewhat. Which could be a literal lifesaver in emergency situations.
The last app on this list is perhaps the most perfect embodiment of a flashlight app that doesn’t ask for more permissions than it should. Flashlight free is a basic, transparent and simple app to use. The developers wanted to address the privacy concerns flashlight apps have caused in the past.
They take care to explain exactly what every feature does, what has changed exactly in each update and anything else users should know. There’s nothing more to say, it’s great.
Now We See the Light!
These excellent flashlight apps make it clear that there’s still plenty of room for innovation when it comes to this genre of software. Phone manufacturers can still make it faster and more convenient for us to activate the built-in flashlight feature. Mostly however, these are just a great set of flashlight apps to light up your life a little.
