I have an android voyager, RCT6773W22B. It's version 5.0. When I first got it, and years after that, I could download at least 5 apps downloaded at a time and have a great sum of pictures in my gallery. I would still have space after this. Over time, I would delete apps I didn't use anymore. If I wanted to download something else and there wasn't enough space, I would delete apps and/or pictures I don't need. Now, I can't download anything due to internal storage. I have no apps, 5 pictures (not taken with the camera), and I've cleared the cache on everything except Chrome. It tells me my internal storage is completely full and I can't move anything to an SD card. What do I do?

I think this is the very similar problem I was having with my old phone.
First, check your Storage in Settings for the information of what takes up your phone's space
Second, if First step doesn't help, instal 3rd-party app, like Disk Usage, and check from there

My suspicion is the .thumbnail files and the database

There are a lot of reasons that can cause this:

• leftover artifacts from uninstalled apps or updates


• download content from apps (videos/ photos from chat applications, maps for navigation, audio files for language learning apps, etc)


• currently kept open browser tabs (my chrome had at one point 50 tabs, it reserved ~1.5gb of space even if closed it but kept the tabs)

If you do a backup of your contacts and other important data, you can try to reset it to factory settings with a wipe of all sd/ internal memory.
If you have a pc to connect your phone by cable AND the knowledge, you could browse the file folders and find the culprit (I would still recommend to clean the files over the phone afterwards but its easier to find what is taking the space)
You could buy as a well a bigger sd card as a temporary solution.

The old (original) applications that came preinstalled on your phone are stored in the operating system part of the flash. As new versions of those applications appear, they are installed in the user part of the flash.

One way to recover some of the "lost" space is to bring applications to the "original" version - the one from flash. This will clear the "new" version that is installed in the "user" flash, freeing space available to you.

Of course, this does means you run older versions of those applications, which is not optimal.

This problem is most critical on 4GB storage phones (old budget smartphones). Some of them have SD card hardware support, but you can't move applications from the internal memory to the flash.

Another relatively easy way to check the storage is to connect the phone to a PC via USB cable and activate on the phone the "file access" mode - you will see "Internal Storage" and "SD Card" sub-folders (or something similar).

Also, +1 for WhatsApp storage of images/videos/...

I solved a similar problem in android 5 doing this:

1 - Settings --> apps.
2 - Go to all apps tab.
3 - Look for "Download manager" or something similar (I do not know the exact translation). It has an arrow pointing down inside a blue circle.
4 - Select it and clear cache. For me, it had more than 1GB cache when I found it.

If your problem is lots of residue files from apps that are redundant and previously uninstalled. Then I'd recommend one of those cleaning apps like clean master, ordinarily its not the sort of app I would regularly use by any means. But I managed to free up >1GB on one my tablets and the next thing I new I could install loads of apps again - to my surprise.

May be worth looking at your apps in settings as well to make sure there's no excessive disk usage from a particular app.

you can check what files or folders occupying storage from adb shell, and delete it from command line. for example du -hxcd1 /storage/emulated/0
