No Name display of the caller

Have the "Simvalley Mobile comfort cellphone XL-901 with Garantruf" (ordered from Amazon, supplied by Pearl) returned because I stood out some deficiencies right away:
1. Although the caller is entered with name on one of the selection buttons, is on a call of that his name not appear on screen, but only its number.
2. The slide switch for the keyboard lock was very stiff and also turned not reliable. -

I have now found that a flip phone for the following reasons is more suitable for the elderly:
1. Finding the answer button when a call is eliminated. (It may be necessary for it to be only found and placed the glasses!)
2. When you end the call by folding the unit is reliably switched off and protected against accidental operation. The special operating an extra key lock deleted. - Better suited therefore m. E. the Powertel M7000.
