It is very difficult to select a new smartphone! Some want fast performance and some want great camera, but possibly the most common concern is the battery life. If the battery life is constantly running out of juice, it doesn't matter how great it is, as it's just going to become another daily annoyance. Keeping that in mind, Symphony mobile has recently launched two smartphones Symphony R20 and Symphony R100 in the market. Both these handsets have been inaugurated by MR. Rezwanul Hoque, Senior Director of the company in a launching ceremony in a restaurant of Dhaka. Marketing Director of Edison Group, Mr. Ashraful Haque, Deputy General Manager of Marketing, Edison Group, Mr. Asaduzzaman and Senior Manager of Marketing, Edison Group, Mr. Zahidul Islam were present during the launching ceremony. Symphony R20 comes with a 4900 mAh battery and Symphony R100 comes with a 4000 mAh battery. In addition Symphony R100 comes with 13 MP & 5 MP cameras with dual flash, Fingerprint, OTG, 4G and some other stunning features. On the other hand Symphony R20 comes with 8 MP & 5 MP cameras, OTG and so on.
