Best Buy Co Inc beat quarterly profit and sales estimates and backed its earnings outlook for the year, as strong demand for mobile phones, calling plans and tablets offset weakness in its TV business.

The retailer, seen as a bellwether in consumer electronics, said its first-quarter net profit was $136 million, or 35 cents a share, compared with $155 million, or 36 cents a share, a year earlier.

Analysts on average were expecting a profit of 33 cents a share, according to Thomson Reuters I/B/E/S.

Sales rose 1.4 percent to $10.94 billion, beating the analysts average estimate of $10.71 billion.
