Scailex Corp, which imports Samsung products in Israel, said on Monday it had been experiencing problems with batteries of the popular Galaxy S4 cellular phone. Scailex said it was making the announcement after local media reported about malfunctioning batteries, and upon request of the Israel Securities Authority. Israels top-selling Yedioth Ahronoth newspaper reported that thousands of the batteries in Israel had a problem with swelling, and that at least 20 batteries had burst into flames. Starting in the third quarter of 2013, we began to receive indications of problems, Scailex said in a statement to the Tel Aviv Stock Exchange.
