Accidentally deleting a few important files from your Android and wondering if you can recover the lost files on your phone? We have the answer.

There is no doubt that Android smartphones have become the indispensable gadgets that are used for our life, work, communication or entertainment. Photos, videos, contacts, call history, documents, and other files produced on the Android device are extremely significant for us. Thus, it would have been inconceivable that you will go through how much pain and suffering at a point when the files lost from our phone.

Need to recover lost Android files? Here's a detailed Android data recovery guide to solving this common issue, and the rest of the article explains some of FAQs.

Before we go ahead, follow a word of warning: stop using your Android phone. Seriously! Should you continue using your device since the files were deleted (e.g.: update software, install new applications, download videos/pictures), the lost data is likely to be written over by new produced content. This will cause that the files are permanently deleted or they can only be partially recovered.

Note: The methods in this article apply to almost all Android phones: Samsung, Huawei, LG, OnePlus, Xiaomi, and more.

Where are deleted files stored on Android?

Believe it not, you can't find the deleted/lost files on your Android phone easily for the reason that smartphones don't have one special place called recycle bin to store all kinds of deleted data, including photos, videos, documents, app data, etc. But if you're lucky, you might retrieve lost files from the trash folder of some apps.

Although the files that were lost are invisible, they don't really disappear from your device - the folder they're stored in gets marked as "unknown" so that the phone won't show those data. Moreover, the phone allows new data to overwrite freely the "unknow" original database file. And so that's why you should discontinue using your Android.

Thankfully, there are some options for recovering lost files on Android phone.

Let's get started.

Option 1: Retrieve lost files from Android trash folder

Just deleting some data on the app by accident - don't be anxious. Some apps have a space called Trash that can keep the deleted files for limited time. Better yet, finding and recovering your recent lost files from trash is in fact pretty simple.

Here we take Android Samsung Galaxy phone as an example. If you delete pictures accidentally on your Samsung when you organize the photo library in the Gallery app, you can directly tap the three-dot icon at the top-right corner, click "Trash", hold the image you want to restore, and tab Restore. A few seconds later, the picture saved in the trash will be back to the library.

Bear in mind that the photo recovery method varies with particular phone model. Should you own a Huawei phone or other Android device, you can google how to recover photo on [your phone model] or go to your phone's official website to find the answer.

If what you lost are some other file types, open the corresponding app (e.g.: WhatsApp, Contacts, Messages, ES File Explorer, etc.), and check whether it provides trash folder for recently deleted data.

Option 2: Recover lost files from Android internal memory

To retrieve files from phone's internal memory, you need the Android data recovery solution for computer. Among heaps of excellent programs dedicated to file restoration, Android Data Recovery is our no.1 choice.

With darn clean interface and easy-to-understand command buttons, it is perfect for both novices and experts. It scans Android's memory quickly and lets you recover multiple files with one click, covering contacts, call logs, messages, WhatsApp, gallery, videos, as well as documents. What we like is that no matter how much data you deleted from your Android, you can select specific file types or particular items to recover, so you really don't have to waste time on full data restoration.

But do note that only after rooting your device and choosing deep scan mode the software can display complete data lost from your phone. And you must ensure the old data is not overwritten. So, repeat again: stop using your Android.
