我们以前都去过那里。当您删除一条短信(text message)后不久才意识到您真的需要它时，那令人痛苦的时刻。
一旦它消失了，你如何找回它？当您的Android 手机(Android phone)没有回收站(recycle bin)时，您甚至从哪里开始检查？
本指南将向您展示如何在您的Android 手机(Android phone)上恢复已删除的短信，以及如何防止它再次发生。
在 Android 手机上恢复已删除的短信(Recovering Deleted Text Messages on an Android Phone)
不过，在你开始恐慌之前，有一些方法可以让你的信息重新回到(getting your messages back)你的手机上。与在 iPhone 上恢复已删除的短信不同，在Android(Android)上恢复它们几乎是不可能的。
在许多情况下，删除已删除的消息（SMS 或 MMS）不会将其从手机系统中完全删除，至少不会立即删除。
您的手机会将其标记为非活动文件，使其不可见且可替换，以便在您删除短信(text message)后立即出现的其他新文件将覆盖或替换它。这就像在纸上写一些东西，然后将其擦除并在其位置上写一些其他东西。
这意味着一旦您发现您删除了一条短信并想要恢复它，请停止使用手机以增加恢复它的机会。否则它可能会在一段时间后被永久清除。(wiped out permanently)
如前所述，由于系统管理短信数据的方式，几乎不可能恢复从Android 设备中删除的短信。(Android device)
与您的计算机不同，您的计算机有一个垃圾桶或回收站，可以在删除之前将所有已删除的文件保存一段时间，而您的Android 设备(Android device)没有，一旦您确认操作，您也无法撤消删除以恢复已删除的文本。
是否可以恢复已删除的文本？(Is It Possible To Recover Deleted Texts?)
无法保证您会收到短信，因为数据可能已经被删除。尝试从它们被删除的位置恢复它们(restore them from the location they’ve been placed)也不是一件容易的事，因为你不会使用正常的方法来接触它们。
就像隐藏在计算机硬盘中等待检索或替换(retrieval or replacement)的已删除文件一样，您的 Android 设备也是如此；在需要空间来保存更多数据之前，将您删除的所有内容（包括短信）保留足够长的时间。
删除消息后，您的Android 设备(Android device)会将其占用的空间更改为“未使用”，并且只有在您继续使用设备时创建新数据时才会覆盖已删除的消息。
在删除的消息被覆盖之前没有特定的持续时间或时间段。(duration or period)不过，您可以做的最好的事情是立即关闭手机或平板电脑(phone or tablet)上的蜂窝数据或WiFi ，并且不要使用它来创建任何新数据。这包括拍摄新照片、创建新文件等。
您最好的选择是将您的设备置于飞行模式(put your device in Airplane mode)，并快速找到一个短信恢复应用程序，该应用程序可以帮助您在 Android 上恢复已删除的消息，以免它们被覆盖。
在 Android 上恢复已删除的短信(Recover Deleted Text Messages on Android)
您立即意识到您已删除重要文本，请将您的设备置于飞行模式(Airplane mode)。确保您没有录制音频(t record audio)、使用相机或尝试创建任何可能覆盖您的短信的新数据。
询问发件人/收件人
这是您发现删除重要短信(text message)后可以立即使用的第一种低成本方法。如果此人的手机上仍有该消息，请索取屏幕截图或让他们将其转发给您。如果没有，请尝试其他可能的解决方案。
使用短信恢复应用
这不是一个万无一失的方法，因为它可能对许多人不起作用。有许多网站为Android设备提供(Android)恢复软件(recovery software)，但它们有很大的缺点。其中一些恢复应用程序(recovery apps)要求您为要恢复的文本付费，即使它们提供免费试用。假设应用程序的开发人员值得信赖并且应用程序确实可以运行，您最终可能会为恢复短信而付出更高的代价。(text message)
同样，SMS 恢复(SMS recovery)应用程序可能需要对您的设备进行root 访问。(root access)这是一个危险的过程，因为它可以访问您设备上的任何文件。默认情况下，包含您的文本的文件夹对您隐藏在Android上受保护的(Android)系统文件夹(system folder)中。这意味着即使您安装了普通的文件浏览器应用程序(file browser app)，您也无法在没有 root 的情况下浏览到该文件夹。
如果不植根您的设备，文本恢复应用程序(recovery apps)可能无法运行。相反，如果您授予此类应用对设备的root 访问权限(root access)，您最终可能会出现空白屏幕，或者您的手机可能会显示安全警告(security warning)。
此外，您可能会发现要求您使用USB 大容量存储协议(USB Mass Storage protocol)进行恢复的软件，该协议不可用。
擦除和恢复您的手机
仅当您在删除短信之前已完全备份您的Android 设备时，这才有效。(Android device)如果您没有备份您的文本，您可以通过转到您的Google Drive 帐户(Google Drive account)开始备份，选择Settings > Google Backup，然后在新菜单中选择SMS 消息。(SMS messages)
如果您的设备上已经安装了Google Drive，它可能已经在备份您的文本。但是，您必须立即恢复已删除的文本，因为Google Drive每 12 到 24 小时更新一次备份。
使用Google Drive恢复已删除短信的挑战在于它是一个存档，因此它会一次将全文历史记录(text history)更新为以前的设置。无法仅恢复单个文本。
保护您的文本(Protect Your Texts)
无论您是否备份了数据，借助数据恢复软件(recovery software)，恢复已删除的消息并不难。我们希望您现在知道万一您误删文本或手机损坏了该怎么办。
上面的提示应该很好地覆盖了你，但接下来，请确保你截取屏幕截图，将备份保存在云端或你的Google Drive 帐户(Google Drive account)中，以便在这些时刻保留你的消息。
How To Recover Deleted Text Messages On Android
We’ve аll been thеre before. The gut-wrenching moment when you delete a text messаge only to realize shortly аfter that you really needed it.
Once it’s gone, how do you get it back? Where do you even begin checking when your Android phone doesn’t have a recycle bin?
This guide will show you how to recover deleted text messages on your Android phone, and what to do to keep it from happening again.
Recovering Deleted Text Messages on an Android Phone
Before you start panicking though, there are ways of getting your messages back on your phone. Unlike recovering deleted text messages on an iPhone, it may be nearly impossible to recover them on Android.
In many cases, trashing a deleted message – SMS or MMS – doesn’t completely remove it from your phone’s system, at least not immediately.
Your phone will mark it as an inactive file, making it invisible and replaceable, such that other new files that come right after you delete the text message will overwrite or replace it. It’s like writing something on paper, then erasing it and writing something else in its place.
What this means is that once you discover you deleted a text message and want it back, stop using your phone to increase your chances of recovering it. Otherwise it’ll probably be wiped out permanently after some time.
As mentioned though, it’s nearly impossible to recover text messages you deleted from your Android device owing to how the system manages texting data.
Unlike your computer, which has a trash can or recycle bin that holds all deleted files for some time before deleting them, your Android device doesn’t have one, neither can you undo the deletion to restore deleted texts once you confirm the action.
Is It Possible To Recover Deleted Texts?
There’s no guarantee that you’ll get your text messages back, because the data may already be erased. It’s also no easy feat trying to restore them from the location they’ve been placed in for deletion, because you won’t be using normal means to reach them.
Like deleted files hidden in a computer’s hard drive waiting for retrieval or replacement, your Android device does the same; keeping everything you delete including text messages around long enough, before the space is needed to save more data.
Once you delete the message, your Android device changes the space it occupied as “unused” and only overwrites the deleted messages when you create new data as you continue using your device.
There’s no specific duration or period of time it takes before the deleted messages are overwritten. The best you can do though is immediately turn off cellular data or WiFi on your phone or tablet and don’t use it to create any new data. This includes taking new photos, creating new files, and so on.
Your best bet is to put your device in Airplane mode, and quickly find an SMS recovery app that can help you recover the deleted messages on your Android before they’re overwritten.
Recover Deleted Text Messages on Android
Immediately you realise you’ve deleted an important text, put your device in Airplane mode. Make sure you don’t record audio, use the camera, or try to create any new data that may overwrite your text messages.
Ask the Sender/Recipient
This is the first low-cost method you can use immediately you realize you deleted an important text message. If the person still has the message on his or her phone, request for a screenshot or ask them to forward it to you. If not, then try the other possible solutions.
Use an SMS Recovery App
This isn’t a foolproof method as it may not work for many people. There are a variety of sites offering recovery software for Android devices, but they have major drawbacks. Some of these recovery apps require you to pay for your texts to be recovered even if they offer a free trial. You may end up paying a higher price just to recover a text message, assuming the app’s developer is trustworthy and the app actually works.
Similarly, an SMS recovery app may require root access to your devices. This is a risky process as it gives access to any file on your device. By default the folder containing your texts is hidden from you in a protected system folder on Android. This means you can’t browse to that folder without rooting, even if you install a normal file browser app.
Without rooting your device, text recovery apps may not work. Instead, you may end up with a blank screen or your phone may display a security warning if you give such apps root access to your device.
Further, you may find software that asks you to use the USB Mass Storage protocol for recovery, which is unavailable.
Wipe and Restore Your Phone
This will only work if you have completely backed up your Android device before deleting the text messages. If you hadn’t backed up your texts, you can start doing so by going to your Google Drive account, select Settings > Google Backup and then select SMS messages in the new menu.
If you already had Google Drive on your device, it’s probably already been backing up your texts. However, you have to restore the deleted text immediately as Google Drive updates its backup every 12 to 24 hours.
The challenge with using Google Drive to restore your deleted text messages is that it’s an archive, so it’ll update the full text history to the previous setting all at once. There’s no way of restoring an individual text only.
Protect Your Texts
Whether you backed up your data or not, it’s not that difficult to recover deleted messages thanks to data recovery software. We hope you now know what to do in the event that you delete a text by mistake or the phone is damaged.
The above tips should cover you pretty well though, but going forward, make sure you take screenshots, keep backups in the cloud or on your Google Drive account to preserve your messages for such moments.
