Also check the simple stuff that can quietly block big downloads on older Kindles: make sure you’ve got a few hundred MB free and that the date/time are correct then toggle Airplane Mode off and on to refresh tokens. Some newer series are KFX-only or include Kindle in Motion, which older e‑ink models can’t open; if so, ask Amazon to push an AZW3 version to your device or use Download & Transfer by USB for that specific Kindle. If it still hangs after that, a factory reset (after syncing and backing up notes) often clears stuck licenses.
Right, smudges on the lens drive me nuts during my outdoor photo sessions too. I found that using a rocket blower to puff away dust first is super helpful and then following up with a microfiber cloth that's slightly moistened does the trick for those stubborn spots.
Works great. Just be gentle no harsh rubbing or you'll regret it, and always store your gear in a clean bag to prevent more buildup yeah that's my quick tip from trial and error.
