Since recently updating my iPhone5 to 9.3.3 I'm finding that it's now quite laggy and when using Safari it randomly quits and takes me to the phones home screen.
Sounds like Safari might be crashing at times. Have you tried clearing all data in Safari (using the options under Settings > Safari) to see if that might help? Perhaps simply restarting the phone might help as well (if you haven't tried that). Also trying something like resetting network settings if not even all settings can sometimes help with things of this nature if nothing else is working.
I doubt it's 9.3 I'm on 9.0.2 and my Safari on both my iPad and iPhone have been lagging like crazy lately. It's so slow at times I'll be typing and it doesn't input what I'm writing until seconds later into the search bar.
