Hello, I am experiencing too much lagging for the last weeks. I use iPhone 6s 64GB running iOS 9.2.1. The problems started soon, not after updating, so I don't think the update is the problem. It's so anoying and I hate it! Do you have this kind of problem? Are apple working on an update to fix finally those lags and crushes?
