Sales Comparison: Galaxy S4 vs. Galaxy S3

Samsung will ship their flagship device Galaxy S4 to 50 countries and later on to a total of 150 countries under 327 network carriers and according to many sources. Samsung will ship 10 million Galaxy S4 units by the end of April.

DigiTimes reported that Samsung expects to sell 30 million Galaxy S4 units in the first 3 months, 10 million units per month. The device will also go on sale for the last week on April in 50 countries and many more countries around the globe after that.

Galaxy S4 is expected to perform a lot better than its predecessor, Galaxy S3, for better design, newer model and amazing features. Samsung projects 10 million sales figure per month for the Galaxy S4 and that makes 30 million units within 3 months compared to the Galaxy S3's 6.5 million units in the second quarter of 2012. However, Galaxy S3 was launched at the start of May 2012 and comparing the two flagship devices is nearly impossible.

No matter what would outcome is, Galaxy S4 has the advantage over HTC One due to supply shortage and dormancy of Apple's iPhone.
