I think there is also another model without camera and even larger keys Perhaps a Senior's organisation in UK can recommend one?
I am hard of hearing and put my ring tone on "outdoor" so I don't miss calls. When confronted with an upgrade recently i decided not to go for the whole touch system and opted for traditional text buttons but touch screen for messages, contacts, FB, internet etc. - though I seriously underuse it.
Anger management!!! Help needed.
