Dixons Carphone warns on profit on tough UK mobile market

LONDON, Aug 24 (Reuters) - Britain's Dixons Carphone Plc downgraded expectations for full-year profit on Thursday, reflecting tougher conditions in the mobile market as customers hold on to handsets for longer and currency fluctuations made new devices more expensive.

The retailer said headline pretax profit for the year was expected to be in range of 360 million pounds to 440 million pounds ($460-562 million).

Analysts had on average forecast 495 million pounds, according to Thomson Reuters data.
