全球定位系统 ( GPS ) 从字面上改变了世界。能够准确地知道你在地球(Earth)表面的位置对商务和旅行产生了深远的影响。每部智能手机都内置了GPS接收器，这意味着您再也不会迷路了。
可悲的是，即使是最有用的技术也会失败，如果您是Android用户，您可能会遇到Android GPS无法正常工作的情况。如果您遇到这种情况，您可以通过以下几种常见方式与上面的卫星重新取得联系。
移动(Move)到不同(Different Spot)的地方并保持耐心(Be Patient)
当您的Android GPS无法正常工作时，问题可能根本不是您的手机！如果您没有足够多的GPS卫星的视线或遇到恶劣天气，那么获得锁定可能很难或不可能。
远离金属物体，让你头顶晴朗的天空，而不是站在高墙旁边，这些都是让你的手机更容易在世界上找到自己位置的方法。
真的是 GPS 问题吗？
一些使用GPS的应用程序还需要有效的数据连接。如果您的WiFi或移动数据连接无法正常工作，这可能是您的应用无法执行其 GPS 相关工作的原因。因此，请尝试切换到不同的WiFi网络，在WiFi和移动数据之间切换，或者只是移动到接收效果更好的地方。
如果您可以访问网站并在其他应用程序中使用数据服务，这可能不是问题。但是，将其作为罪魁祸首消除起来既快速又容易。
您是否尝试过将其关闭(Off)并再次(Again)打开？
好的，您可能已经(have )尝试过了，但是为了彻底，我们必须首先提出最快和最明显的解决方案。如果您不知道，在应用程序阴影的快速菜单中有一个GPS功能切换。(GPS)
“应用程序阴影”是您通过从屏幕顶部滑动访问的抽屉。不同的 Android(Different Android)皮肤可能看起来并不完全相同，但您仍会在此处找到某种GPS切换。
通过翻转这个虚拟开关，您还可以重置GPS硬件。通常这足以重新启动获取GPS锁定的过程。
重启和飞行模式
如果快速切换翻转似乎不起作用，那么可以尝试更多的核选项。您可以简单地打开飞行模式(Airplane Mode)，它会禁用所有无线通信。等待几秒钟，然后再次禁用它。有时，当只是切换GPS不起作用时，这会起作用。
下一步是完全重启手机。如果切换GPS、飞行模式(Airplane Mode)和重新启动不起作用，则表明问题归结为比故障更持久的问题。
尝试使用更准确的模式
现代 Android(Modern Android)手机可以通过各种方式帮助提高GPS精度。如果您的GPS需要很长时间才能锁定或性能不佳，您应该检查是否启用了这些准确度助手。
这很容易做到。只需拉下应用程序阴影并点击并按住位置快捷方式即可转到其设置。
根据您的Android版本或手机品牌，确切的名称或方法可能会有所不同，但这是在大多数情况下快速访问它的方法。或者，您可以转到Android设置页面并在那里查找位置(Location)设置。
一个在位置(Location)设置页面上，有两个兴趣点。首先(First)，检查您的手机是否设置为使用蓝牙(Bluetooth)和WiFi以提高GPS精度。如果启用，您的手机可以寻找本地WiFi热点或已知的蓝牙(Bluetooth)信标，这可以立即指示您的大致位置。
您还应该检查是否启用了Google 位置准确性(Google Location Accuracy)。
这应该有助于显着改善定位。
为手机充电或禁用省电模式(Power Saving Mode)
GPS功能非常耗电。当您的手机电量过低时，它可能会切换到特殊的省电模式。无论是作为Android一部分的标准版本，还是由您的手机制造商调整的修改版本。
因此，如果您的电池处于红色状态且省电模式已打开，禁用可能会使您的GPS功能再次正常工作。当然，尽管您的手机电池现在会更快耗尽。或者，您可以尝试简单地将手机插入，这将禁用省电模式。这就是为什么随身携带移动电源(power bank)或 USB 车载充电器是个好主意。
重新安装或更新(Or Update)您的地图(Maps)应用程序
有时问题不是手机的GPS功能，而是打算利用它的应用程序。您可以通过切换到另一个使用GPS(GPS)的不相关应用程序来确认这一点。如果该应用程序运行良好，那么我们必须将注意力转向不合作的罪犯。
基本上你可以在这里做两件事。一种是前往您的应用商店，查看您的地图应用程序是否有待更新。如果它的版本太落后，它可能无法在总部使用该服务。如果没有待处理的更新，只需卸载并重新安装该应用程序即可。
使用 GPS 诊断应用程序
(Apps)谷歌地图(Google Maps)等应用程序在您和手机中的GPS接收器硬件之间放置了一个用户友好的软件层。应该是这样，但是当应用程序停止正常工作时，它也会变得有点神秘。
幸运的是，有适用于Android手机的(Android)GPS应用程序可以向您显示GPS硬件的原始读数。这对于快速将您的精确坐标传递给某人和诊断GPS问题都很有用。
我们可以推荐的一款应用是GPS 状态和工具箱(GPS Status and Toolbox)，它可以为您提供GPS装置在屏幕上显示的所有数字。如果您有另一部装有该应用程序的手机，您可以比较读数以确保它看起来正确，如果它什么也没显示或出现错误，您可能正在查看需要致电维修店的硬件问题。
再次上路
突然在陌生的领域迷路可能有点可怕，但希望在看完这份潜在问题清单后，你很快就会到达目的地。然而，没有任何技术是完美的，所以我们仍然建议您购买一张实际的纸质地图并随身携带，以防万一您根本无法让Android GPS工作或您只是没电了。
GPS是一项令人着迷的技术，如果您有时间，请查看HDG 解释：GPS 是如何工作的？(HDG Explains : How Does GPS Work?)以便更好地了解这一切的具体细节。如果您的问题是缺乏连接而不是GPS信号锁定问题，您还应该查看适用于 Android 的 9 个最佳免费离线 GPS 应用程序(9 Best Free Offline GPS Apps For Android)。下次您超出信号范围时，它可能只会让您免于绕圈子！
Android GPS Not Working? Here’s How To Fix It
The global positioning system (GPS) has literally changed thе world. Being able to tell exactlу where you are on the surface of the Earth has had fаr-reaching effects on business and travel. The fact that every smartphone has а GPS receiver built-in means that you nеver have to be lost again.
Sadly, even the most useful technologies fail and if you’re an Android user you might encounter situations where your Android GPS is not working. If that’s happened to you, here are a few common ways you can get back in touch with the satellites above.
Move To A Different Spot & Be Patient
When your Android GPS is not working, the problem might not be your phone at all! If you don’t have line of sight with enough GPS satellites or are experiencing inclement weather, then acquiring a lock might be hard or impossible.
Moving away from metallic objects, getting clear sky above you and not standing next to high walls are all ways you can make it easier for your phone to find its place in the world.
Is It Really a GPS Problem?
Some apps that use GPS also need a working data connection. If your WiFi or mobile data connections aren’t working correctly, this might be the reason your app isn’t doing its GPS-related job. So try switching to a different WiFi network, switching between WiFi and mobile data or simply moving to a spot with better reception.
If you can access websites and use data services in other apps, this probably isn’t the problem. However, it’s quick and easy to eliminate it as a culprit.
Have You Tried Turning It Off & On Again?
OK, you probably have tried this, but for the sake of being thorough we have to suggest the quickest and most obvious solution first. In case you didn’t know, there’s a toggle for GPS functionality in the quick menu of the app shade.
The “app shade” is this drawer that you access by swiping from the top of the screen. Different Android skins might not look exactly the same, but nonetheless you’ll find some sort of GPS toggle here.
By flipping this virtual switch, you also reset the GPS hardware. Often this is enough to restart the process of acquiring a GPS lock.
Rebooting & Airplane Mode
If that quick toggle flip doesn’t seem to do the trick, there’s a somewhat more nuclear option to try. You can simply toggle on Airplane Mode, which disables all wireless communication. Wait a few seconds and then disable it again. Sometimes this will work when just toggling GPS doesn’t.
The next step would be to reboot the phone entirely. If toggling GPS, Airplane Mode and rebooting don’t work, that indicates the problem is down to something more permanent than a glitch.
Try Using Better Accuracy Modes
Modern Android phones can help boost GPS accuracy in various ways. If your GPS is taking forever to get a lock or is performing poorly, you should check whether you have these accuracy helpers enabled or not.
This is pretty easy to do. Simply pull down the app shade and tap and hold the location shortcut to go to its settings.
Depending on your Android version or handset brand, the exact name or method may vary, but this is how to access it quickly in most cases. Alternatively, you can go to the Android settings page and look for Location settings there.
One on the Location settings page, there are two stops of interest. First, check whether your phone is set to use Bluetooth and WiFi to improve GPS accuracy. If enabled, your phone can look for local WiFi hotspots or known Bluetooth beacons, which gives it an immediate indicator of your rough location.
You should also check if Google Location Accuracy is toggled on.
This should help improve positioning significantly.
Charge Your Phone Or Disable Power Saving Mode
GPS functionality is pretty power hungry. When your phone’s charge is too low it may switch into a special power saving mode. Either the standard one that’s part of Android or perhaps a more modified one tweaked by your phone maker.
So if your battery is in the red and power saving mode is on, disabling might get your GPS function working properly again. Although, of course, your phone battery will die much more quickly now. Alternatively, you can try to simply plug the phone in, which will disable power saving mode. This is why it’s a good idea to always have a power bank or a USB car charger close at hand.
Reinstall Or Update Your Maps Application
Sometimes it’s not your phone’s GPS functionality that’s the problem, but the app that’s meant to make use of it. You can confirm this by switching to another unrelated application that uses GPS. If that app works just fine, then we have to turn our attention to the uncooperative offender.
There are basically two things you can do here. One is to head over to your app store and see whether your maps application has a pending update. If it’s version gets too far behind, it might not be able to work with the service back at home base. If there are no updates pending, simply uninstalling and reinstalling the app can do the trick.
Use A GPS Diagnostic App
Apps like Google Maps put a user-friendly layer of software between you and the GPS receiver hardware in your phone. That’s as it should be, but it can also make it a little mysterious when the app stops working correctly.
Luckily there are GPS apps for Android phones that will show you the raw readings from the GPS hardware. This is both useful for quickly relaying your exact coordinates to someone and to diagnose GPS problems.
One app we can recommend is GPS Status and Toolbox, which gives you all the numbers your GPS unit spits out right there on the screen. If you have another phone with the app, you can compare the readings to make sure it looks right and if it shows nothing at all or gives an error, you might be looking at a hardware issue requiring a call to a repair shop.
On The Road Again
Suddenly losing your way in unfamiliar territory can be a little scary, but hopefully after going through this checklist of potential problems you’ll be at your destination in no time. No technology is perfect however, so we do still recommend that you buy an actual paper map and keep it with you just in case you simply can’t get Android GPS working or you simply run out of power.
GPS is a fascinating technology and if you have the time check out HDG Explains : How Does GPS Work? for a better understanding of the nuts and bolts of it all. If your problem is a lack of connectivity rather than GPS signal lock issues, you should also have a look at the 9 Best Free Offline GPS Apps For Android. It might just save you from wandering in circles the next time you’re out of signal range!
