A new study out of the UK that monitored consumer sentiment on social networks when the iPhone 5 launched has found that 20 percent of posts were critical of the device. By comparison, the launch of the Galaxy S4 attracted around half as much criticism at 11 percent, reports the Daily Mail. Criticisms leveled at the iPhone 5 was targeted at the new Lightning connector, the problems with the Maps app and that the design was not different enough to the iPhone 4S that preceded it.
