Smartphone accessibility also includes screen magnification zoom controls and the ability to select colour contrast settings.
Under settings/accessibility you should be able to magnify and change colour contrasts. The best phone for an individual often comes down to personal preference so we recommend trying before buying. You should be able to try out a range of phones in your local mobile phone store.
Synaptic phones have a range of options for high contrast and magnification.
Where available use smart invert screen colours. Rather than inverting all colours including images, which can make photos look strange, smart invert only inverts text and the background colour, keeping images the correct colour. This helps to reduce glare, retaining useful image qualities.
