How could he solve the problem of reading e-books on his old phone? (Memory Card)

The solution to the problem of reading e-books on the old phone was as follows: 1. Confirm that the elderly phone supports the function of reading e-books. Some old computers may not support all e-book format and only support some specific format, so you need to confirm whether the old computer supports e-book format. 2. Clone the e-book file to the memory card of the old phone. After copying the e-book file to the memory card, the old phone could read the e-book through the memory card. 3. Set the reading mode of the old man. Some old phones might not support automatic reading mode and required manual settings. You can go to the settings-applications-e-book option and choose "open as" the e-book file in the memory card and then save the settings. 4. Use reading software. Some old computers might not support the built-in reading software and needed to use third-party reading software. You can search for and download a reading software suitable for the elderly phone in the app store and install it on the elderly phone. It was important to pay attention to the battery life and screen brightness of the old phone when reading e-books. Don't overuse or use too much brightness, and don't delete the contents of the e-book at will.
