Tizen is an open-source, Linux-based operating system developed and distributed by Samsung. Tizen OS is Samsung’s major operating system for their smartwatch and Smart TVs, but later, it became the main operating system for their Z lineup of smartphones. Tizen powered smartphone are targeted for developing markets as an Android alternative.
On January 2015, Samsung released its first Tizen smartphone in India for Rs. 3,990. Samsung Z1 is a budget smartphone with a 4-inch 480p display, 4GB of ROM and 768MB of RAM. Of course, it’s not the kind of smartphone that the company would love to brag about but Samsung is serious of popularising the OS that on October the same year they released another Tizen smartphone, the Samsung Z3, an upgrade to Z1. Z3 features a 5-inch 720p HD display with 1GB of RAM running on 1.3GHz and 8GB of expandable storage. The 8MP rear-facing camera is also a notable upgrade from the 3.1MP camera of Z1.
Weird enough, Samsung again decided to released another Tizen-powered smartphone in August 2016 which is definitely not an upgrade to Z3, but the specs show that it is rather and upgrade to Z1. The name also suggests it. Z2 features a 4-inch 480p display with 8GB of ROM and 1GB of RAM running at 1.5GHz and the same 1500mAh of battery from Z1 compared to 2600mAh of Z3.
Later this week, Samsung refreshes their Z line up with their newest Tizen-powered smartphone, the Samsung Z4. Samsung Z4 is an entry level LTE device that features the newest Tizen 3.0. There’s no mention of the changes from the later version, but it’s quite mentioning that previous versions of Tizen had huge security problems. On April this year, Vice via their Motherboard website reported that Amihai Neiderman, an Israeli security expert, has found more than 40 zero-day vulnerabilities in Tizen’s code calling it “the worst he’d ever seen”. We should expect Samsung to fix this problem with the latest version of Tizen OS.
Samsung Z4 will have a 4.50-inch 480p display with 16GB of ROM and 1GB of RAM clocked at 1.5GHz. Unlike its predecessor, the Z3, Z4 will pack with 2500mAh of removable battery. The camera is somehow a downgrade from the 8MP rear-facing camera of Z3, that if we mention the megapixel count. Z4 will have a f/2.2 5MP rear-facing camera with dual-LED flash and 5MP camera on the front also with LED flash good for low-light selfies.
Z4 is a good alternative for people who doesn’t like the Android OS, and although we might not be expecting a higher-end Tizen running smartphone, at least now, we know that Samsung is serious with its homegrown OS and they continues to develop and improve it through the years. In fact, Samsung’s Tizen overtook Android Wear market share for Q1 of 2017 making it the second most popular smartwatch OS just behind Apple Watch.
Samsung Z4 will become available later this month, starting in India and other select markets. The device will also be showcased at the Tizen Developer Conference on May 16 in San Fransisco.
