Safari Keeps Crashing in iPhone 4s on iOS 9.2.1 !!

And what about clearing all Safari data?

 

You can try playing with some other Safari settings (including any iCloud one possibly) to see if that might change anything. Alternatively, assuming restarting the phone has already been attempted, perhaps resetting some settings (like network settings), if not all settings might be worth a try.

 

Same thing happened on mine after the update, here is what fixed it: settings>safari>advanced>website data then tap remove all. Hopefully this helps
