in iOS 9, the system font had changed from Helvetica to San Francisco. I love the change! However, it doesn't change it in pages in Safari. Is there a way to change it to San Francisco? Thanks!

You can't change fonts without jailbreaking. If your device is jailbroken, you can copy your preferred SFUI font family from /System/Library/Fonts/CoreUI/ over the top of each Helvetica font in /System/Library/Fonts/Core/.

  • @awe I would not recommend it to everyone. It's not ‘hard’ but you do need some knowledge of the workings of iOS. Risks can be mitigated if you have a backup and are willing to update iOS. If you really want to try and you acknowledge the risks, you are welcome to ask a completely separate question regarding the specific version of iOS you are trying to jailbreak and the device model on which you are attempting it.
