Agree for a few comments above.

 

But the bit that stands out is the

Main performance issue is that when  you unlocking the phone it is effectively unusable for upto 5 minutes

 

Is the phone being turned off alot, what if she leaves it on all the time?

 

Has background sync been turned off?

 

Suggest a quick clean up of a few apps as well, clear the cache etc.

 

 

 

Phone is never turned off and background sync is turned on. I see the same issues with my old Samsung Tablet which did suspend a lot of background syncing when the screen is off for an extended period, so we've checked all of the usual suspects with her phone.

I'll take a fresh look tonight as does not meet the required WAF.
