Back in January, Samsung launched its first Tizen-powered smartphone, the Z1. Despite rumors that the Z1 encountered a cold reception during its first month of availability, Samsung managed to sell 1 million units. With that number in mind, it looks like Samsung plans to release the Z1's successor, the Z3, sometime this year.

According to SamMobile, the Z3 could be an improvement on the Z1 in just about every aspect, particularly the display. Whereas the Z1 packed a 4-inch, 480 x 800 pixel-resolution screen, the Z3 reportedly packs a 5-inch, 720 x 1,280 pixel Super AMOLED screen. Crucially, the Z3 also allegedly includes twice the amount of RAM with 1.5GB, where the Z1 only includes 768MB of RAM.

Taking a peek under the hood, the Z3 is reportedly powered by a 1.3GHz quad-core Spreadtrum SC7730S processor, which is quite an improvement from the Z1's dual-core 1.2GHz processor. Keeping the lights on is a 2,600mAh battery, which will theoretically be enough to give the phone all-day battery life with adequate screen-on times.

Around the back, there's an 8-megapixel camera with LED flash, and the front-facing snapper is a 5-megapixel camera. Unfortunately, the Z3 looks to only include 8GB of internal storage. If the Z3 is anything like the Z1, however, it will have a MicroSD card slot for expanding that small amount.

Speaking of slots, due to Samsung's focus on the Indian market when it comes to Tizen, the Z3 looks to include dual-SIM card support. It's unknown whether the Z3 itself will have 4G LTE capabilities, however, seeing as the Z1 only supported up to 3G connectivity.

Interestingly enough, the Z3 was reportedly sent to India for testing purposes and a "partnering event" recently, leading us to believe it could be announced during Samsung's Indian Tizen Developer Summit later this month. Much like the Z1, the Z3 will likely be released in India, though further international availability is up in the air.
