Apple's iPhone 4 has come under the spotlight with a number of left-handers unhappy with the design of the handset as it forces them to use their wrong hand to operate the device if they do not want to block the reception antenna.
Some people were unable to call or surf the internet on the Apple iPhone 4, which had hit shops in 2010, as holding the device in the left hand could in some cases cover the phone's antenna, thereby cutting off reception.
Agnes Maria Forsthofer, a member of an association for left-handed people in Germany, pointed out that 'there are essentially no devices fitted for left-handers.'
According to News24, Barbara Sattler, who heads an information centre for left-handers in Germany, pointed out that the 'number pad for example is difficult to use with your left hand'.
"There are only a few keyboards where the number pad is on the left side," Sattler said.
Sattler suggested that left-handers should rather get a separate number pad with a USB connection, like those available for laptops.
