My Mum has an S4 mini and a 9" tablet, but wants to go with one device, partly because the tablet broke. Her specification is:

• Must be suitable for both use as a phone and playing games like solitaire
• No slower than the S4 mini - note that she doesn't need a flagship, but does want good quality
• 5.5" screen - needs to be a practical size for a 5 foot tall woman. The Galaxy note is too large for her.
• $300 to $600. Prefer a very good phone at $600 to a good phone at $300.
• There must be a decent quality case available, as Mum tends to drop phones on a fairly regular basis.
• Update: A good camera would be useful, suitable for an overseas trip. Working overseas (Thailand / Cambodia) would be handy too.

Suggestions appreciated.  Mauricio suggested the Huawei P8, which is 5.2", so probably not quite big enough but I'll put to her as an option.
