By Harro Ten Wolde and Klaus Lauer BERLIN (Reuters) – Samsung Electronics Co Ltd, the worlds biggest mobile phone maker, unveiled new versions of its Galaxy Note smartphone on Wednesday after previous design miscues cost it customers in the large-screen phone market it pioneered. The new Galaxy Note 4 features a crisper, 5.7-inch display in a metal frame, reflecting Samsungs latest design strategy to keep pace with rivals including Apple Inc, which is expected to launch its first large-screen phones next week. The Note 4 is key to a recovery by Samsung Electronics, which faced initial derision at the idea of callers holding elephantine screens up to their ears. Mobile phone analysts said that, while packed full of hundreds of features and many of the latest hardware specs, there is little in the Note 4 to excite new users.
