#### How can I see how many chapters I've downloaded?
This can be done by enabling **Download badges** under **<MaterialIconicon-name="class"/> My library**.
::: guide
Enable it by going to **<MaterialIconicon-name="class"/> My library** → **<MaterialIconicon-name="filter_list"/> Filter** → **Display** section then checking the **Download badges** option in the bottom.

#### Some covers are white after restoring from backup
The URL to the cover has probably changed. To fix this, refresh the metadata of your library.
::: guide
Refresh your metadata by going to **[<MaterialIcon icon-name="settings"/> Settings](/help/guides/settings)** → **[<MaterialIcon icon-name="code"/> Advanced](/help/guides/advanced)** then pressing **[Refresh library metadata](/help/guides/advanced/#refresh-library-metadata)**.

#### How do I ignore chapters from certain scanlator groups?
Every now and then you find a manga that is translated by more than one group, because of this you get multiple releases for every chapter in the manga. To fix this the easiest way is to change sorting to **Total chapters**. You won't see any changes but, when you start reading you'll automatically skip the duplicate releases.
::: guide
Change library sorting by going to **<MaterialIconicon-name="class"/> My library** → **<MaterialIconicon-name="filter_list"/> Filter** → **Sort** section then in this case selecting **Total chapters**.

#### Why do I see `attempt to invoke virtual method 'com.hippo.unifile...`?
This error can be caused by a variety of reasons, all to do with storage.
::: guide
- Most commonly it is caused by full storage, check to see if your device or SD Card is full
- **Tachiyomi** doesn't have access to SD card enabled in permissions for the app
- If you're downloading and this error pops up, that means the app might not be able to access the folder you're trying to download to.
- This may be because the folder is corrupted or does not exist. Use a file manager to check that the folder(s) actually exist and every folder in the sequence is available and accessible.
- The drive you're writing to is corrupted. Check using a file manager to see if it is accessible.

### Reader
#### Why are some images not displayed?
Aside from network issues, it could be because the images are too big or that the decoder doesn't support that image type.
### Downloads
#### What happened to the simultaneous downloads feature?
It was removed to prevent IP bans caused by too many requests. We know that speed is being sacrificed but it's better than not being able to access a source at all.
#### Downloads are unstable
Be aware that it could be a network issue on your device or on the catalog you are trying to download from.
#### Can you make it possible to store manga on both internal storage and external SD-card?
At the moment, no. You could try using symlinks but that requires having your phone rooted.

We recommend you to read [this](/help/guides/reading-local-manga) guide on how to do so.
#### I can't find the Tachiyomi folder
If you don't see a **Tachiyomi** folder on your device, try downloading a chapter of any manga or creating a backup so that the folder can be created.
### Application Updates
#### How do I enable automatic updates?
The **Tachiyomi** app now has in-app updating for both stable and preview versions. It happens automatically in the background if you got **[Check for updates](/help/guides/about/#check-for-updates)** enabled.
::: guide
If you go to **[<MaterialIcon icon-name="settings"/> Settings](/help/guides/settings)** → **[<MaterialIcon icon-name="help"/> About](/help/guides/about)** you will find the **[Check for updates](/help/guides/about/#check-for-updates)** toggle, you can also press **[Version](/help/guides/about/#version)** to force check for updates.

### User Interface
#### Can I change the app language?
**Tachiyomi** is as of writing available in 35 different languages. By default, the app follows the language used on your device.

### Miscellaneous
#### What happened to the F-Droid version?
F-Droid is no longer an officially supported option. Both the stable and preview builds now include an auto-update mechanism.
An unofficial F-Droid repo is available at [tachi.efreakbnc.net](https://tachi.efreakbnc.net).
#### Why do I get a `App not installed` error when installing?
You may encounter this if you're installing an official build over an existing F-Droid build due to differing signatures.
Backup your data, uninstall the app, then restore the data in the fresh install.
#### iOS Version
There is currently no iOS version and there are no plans for one and since iOS and Android apps don't share code it's hard to port.
#### I lost everything, what now?
**Tachiyomi** is still in beta and some design changes or unexpected errors may lead to data loss. While we try for them not to happen, sometimes it is unavoidable. To avoid this in the future, you can use the automatic backup feature.
The most popular are **MangaDex**, **MangaSee** and **Mangakakalot**, these are large sites which host content from scanlators. Description of some popular sources are listed below:
- Fastest manga updates: **Mangadex** and scanlator sources
- Largest manga library: **Mangakakalot** (found in **Mangabox** extension)
- High quality scans and official translation: **Mangasee**
Most of the scanlator sources are part of **Multi-source** extensions, which contain multiple sources. For example, extensions like **Genkan**, **Madara**, **FoolSlide** and **ComiCake** which contain sources which host directly from the scanlators' own websites.
In some cases your phone might have some issues downloading the extensions, in those cases you can try installing them yourselves directly from the source.
To install just download the file for the extension you want and then install it, like how you installed **Tachiyomi**.
When installing your first extension and are prompted that your phone isn't allowed to install unknown apps from that source, simply follow the prompt to allow it.
If you need more help regarding this, read [this](https://www.theandroidsoul.com/how-to-allow-apps-installation-from-unknown-sources-on-android-9-pie/)
Extensions for **Tachiyomi** are technically installed the same as normal apps. Either you uninstall them through the app section on your phones settings or you go can do it in the app.
To uninstall an extension from within **Tachiyomi**, go to **<MaterialIconicon-name="extension"/> Extensions** then tap **Uninstall** on the extension you want to remove.
- **Tachiyomi** no longer have pre-installed extensions, this means that you will need to install extensions you want to use from the **<MaterialIconicon-name="extension"/> Extensions** menu.
- If you're getting the `Loader not implemented` error after clicking on a manga, you will need to reinstall the extensions you used to use. Which number in the menu corresponds to which is below.
If you've freshly reinstalled the **Tachiyomi** app, the installed extensions might not show up in **<MaterialIconicon-name="explore"/> Catalogues** until you enable them.
To fix this, go to **<MaterialIconicon-name="explore"/> Catalogues**→**[<MaterialIconicon-name="settings"/> Sources](/help/guides/catalogues/#sources)**. Now you can proceed to enabling your desired sources.
- Download the extension for that source from **<MaterialIconicon-name="extension"/> Extensions** if it exists, read [this](/help/faq/#which-sources-are-in-the-multi-source-extensions) for a list of which extensions contains what sources.
It means that the respective extension for the manga is not installed. To fix, install the extension for the manga. If it still doesn't work, uninstall then reinstall the extension again.
