Samsung Galaxy S5
Samsung tweaked rather than overhauled its flagship smartphone. The S5 is dust-and-water-resistant, has a faster 2.5-GHz quad-core processor, still with 2GB RAM, and Android 4.4. The 5.1-inch screen has the same 1920 by 1080 pixel resolution as the S3; storage options are 16G or 32GB, along with a microSD slot. New: a fingerprint scanner, and a main camera with higher specs, like 16 instead of 13 megapixels. Networking: category 4 LTE and 802.11ac with MIMO. It has something called “download booster,” which allegedly boosts data speeds by “bonding Wi-Fi and LTE,” according to Samsung. Battery life: up to 10 hours on LTE. Available: April 11.
