• 🔹 In the reader settings, specify the path to the folder with books manually (for example, /sdcard/Download/Books/).
• 🔹 Move books to internal memory if they are on SD card (some readers do not work with external drives).

Problem 2: The reader crashes when opening .pdf.

• 🔹 Update the application to the latest version.

• 🔹 If the PDF weighs more than 50 MB, split it into parts using PDF Splitter.

Problem 3: Synchronization with the cloud does not work.

• 🔹 Check your Internet connection and application permissions (access to accounts and storage).
• 🔹 Re-authorize in the cloud service (Dropbox, Google Drive).
• 🔹 In the reader settings, enable Auto-sync and set the interval (for example, every 6 hours).

• 📧 Email and cloud services: Download the book to Google Drive or Yandex Disk, then open it through the built-in viewer. Suitable for one-time readings.
• 🤖 Telegram bots: Bots like @manybooksbot or @booksee_bot can send books to chat in the format .epub or .fb2.
• 💻 Remote access: Set up access to your home library via Calibre-server or KooReader via a local network.

For reading comics or manga you can use specialized applications:

• 🎨 Tachiyomi (for manga, requires manual installation).
• 📖 Perfect Viewer (for .cbz/.cbr).

Important: some browser readers and Telegram bots can distribute pirated content. Before using, make sure that the source is legal to avoid copyright problems.

Reading books on a smartphone can quickly drain the battery, especially if Wi-Fi or mobile data to synchronize. To extend the operating time:

• 🔋 Turn on Airplane modeif you do not need synchronization.
• 📉 Reduce the screen brightness to 30-40% (dark theme is enough and 20%).
• ⏳ Set the automatic timer turn off the screen for 1 minute (in Android settings).
