If you are experiencing the following, you are not alone.

• When you open an app, it take a long time to load up.
• some apps shows white screen or other color when you try to open it.
  
• The touchscreen responds slow to touch
• occasional freezing.
• if you type in pass code, it hesitate for few moments before it opens up

I have experienced all these. I will have to tell you that, I have few personal emails connected to my iphone.
