Hi just to say there are three issues that crop up often
a) battery charging issues with non ideal cables and chargers.
b) the quality of the images using the default camera app
and
c) Issue of audibility for the person you are calling if using hands free or WhatsApp for example. This is a recognised software issue that has occurred apparently after an update and is in the pipeline for a fix.
Glad you are happy with your decision to buy Fair
