I had the same issue with my Kindle last month, and it drove me nuts until I figured it out. The problem might not be with the settings themselves but with the book format. Some older or PDF-converted books don’t support font customization because they’re fixed-layout files.
Another possibility is a glitch in the update. Kindles sometimes need a hard reset after software changes. Hold the power button for 40 seconds until it restarts. If that doesn’t work, try deregistering and reregistering your device. It sounds extreme, but it often fixes stubborn settings issues. Also, double-check that you’re not in 'Publisher Fonts' mode—that locks the size. Go to 'Aa' > 'Font' and toggle it off.

I ran into this issue last week after updating my Kindle, and it was frustrating. The text size wouldn’t adjust no matter how many times I tapped the font settings. I realized the problem was tied to the book format. Some older PDFs or sideloaded files don’t support dynamic font changes. Converting the file to EPUB or AZW3 using Calibre fixed it for me. Another thing to check is whether the publisher locked the formatting—some DRM-protected books restrict customization. If it’s a Kindle Store purchase, try deleting and redownloading the book. Sometimes the update glitches the file.
Restarting the device also helps. Hold the power button for 40 seconds until it reboots. If none of this works, resetting font settings to default might clear the bug. Go to 'Display Settings' and tap 'Reset.'

I’ve had my Kindle for years, and the font size issue is something I’ve wrestled with too. Sometimes, it feels like the settings just don’t stick, no matter how many times you adjust them. One thing I’ve noticed is that certain books, especially older ones or PDFs, don’t support dynamic font resizing as smoothly as newer EPUBs. If you’re dealing with a PDF, the font might be locked because the file is essentially an image.
Another culprit could be the Kindle’s software. I’ve had instances where a minor glitch prevents the font size from changing until I restart the device. Also, check if you’re accidentally pinching the screen, which can trigger zoom instead of font adjustment. If all else fails, a factory reset might be the nuclear option, but backup your books first!

I ran into this issue last week after updating my Kindle, and it was super frustrating. The font just wouldn’t switch no matter what I tried. Turns out, the update sometimes resets custom settings or glitches during installation. I fixed it by restarting my Kindle—holding the power button for 40 seconds until it rebooted. After that, the font options worked again. If that doesn’t help, check if the book format supports font changes. Some older PDFs or sideloaded files might not have the feature. Also, make sure your Kindle’s software is fully up to date. Sometimes a follow-up patch fixes这些小bugs.

As an avid Kindle user who loves customizing my reading experience, I've spent a lot of time figuring out the best ways to adjust font size quickly. There isn't a single 'shortcut' button, but the fastest method is tapping the top of the screen to bring up the toolbar, then selecting the 'Aa' menu. From there, you can increase or decrease font size with the '+' and '-' buttons.
Another trick I use is holding two fingers on the screen and pinching outward to zoom in or inward to zoom out, which changes the font size dynamically. This gesture works in most books and is faster than navigating menus. For those who read in bright or dark environments, adjusting font size can make a huge difference in comfort, so I recommend experimenting with these methods to find what works best for you.

I’ve had my Kindle for years, and I’ve run into this issue a few times. The font size adjustment might not work if your device is frozen or needs a restart. Try holding the power button for about 40 seconds until it reboots. Sometimes, the problem is caused by a corrupted book file. If it’s happening with a specific book, delete it and redownload it from your library.
Another possibility is that the book’s formatting doesn’t allow font changes. Some PDFs or older eBooks have fixed formatting. Convert the file to a Kindle-friendly format like AZW3 or MOBI using Calibre. Also, check if your Kindle’s software is up to date. Go to Settings > Device Options > Advanced Options > Update Your Kindle. If none of these work, a factory reset might be necessary, but back up your data first.

Changing the font size in the Kindle app is super straightforward and something I do all the time to make reading more comfortable. When you're reading a book, just tap anywhere on the screen to bring up the menu. At the top, you'll see an 'Aa' icon—that's your gateway to customization. Tap on it, and a menu will pop up with options like 'Font Size,' 'Font Style,' and more. To adjust the size, simply slide the bar under 'Font Size' to the left for smaller text or to the right for larger text. It’s instant, so you can see the changes right away. I love how easy it is to tweak it based on my mood or lighting conditions. If I’m reading in dim light, I’ll bump up the size, but if I’m in a bright room, I might go smaller to fit more text on the screen. It’s a small feature, but it makes a huge difference in my reading experience.

I've encountered this issue multiple times, and it can be incredibly frustrating. The Kindle font size not staying saved usually happens due to a few common reasons. First, if your device isn't syncing properly with your Amazon account, settings like font size might reset. Make sure your Kindle is connected to Wi-Fi and try manually syncing it.
Another possible culprit is the book format itself. Some older or non-Amazon eBooks might not support persistent font settings. If you sideloaded the book, converting it to a Kindle-friendly format like MOBI or AZW3 using Calibre could help. Also, check if you have the 'Publisher Font' option enabled in the Aa menu, as this can override your custom settings.
Lastly, a software glitch might be causing the problem. Restarting your Kindle or even performing a hard reset (holding the power button for 40 seconds) often resolves these minor bugs. If none of these work, contacting Amazon support might be your best bet, as they can check for deeper issues with your device or account settings.
