Taiwan company ASUS last year came up with series of zenfones.
Zenfone 2 Laser ZE550KL is one among them.
its a well build device, one of the best in the budget segment.
talking about specs,
has 5.5 inch 720p display at 267 ppi covered by corning gorrilla glass 4. Though its just 720p display then also you arent going to see any pixelation. Colors are vivid accurate, (some has yellow tone, which can be resolved in temp segment), sunlight visibility is just ok.
beneath the hood:
qualcomm snapdragon 410 at 1.2 Ghz.
2gb ddr3 ram.
13mp rear camera with dual tone led flash and laser, 5mp front camera, by pixel master technology.
dual sim support.
sound is loud enough.
volume rockers are located below the primary camera.
adreno 306 gpu.
android lollipop 5.1 out of the box.
16gb internal, expandable upto 128gigs.
my thoughts: all in all a nice device, go get it.
