Asus, now a days, becomes a reliable brand of smartphones. Its product ZenFone Max ZC550KL is the father of all similar brand in battery backup. it has 5000mAh battery by which you can use the device for 36-48 hours. It has 5.5 inch big display with 1920-1080 resolution for video and gaming experiences. Though it has 2Gb ram and 16 GB internal storage, it has hanging problems. I said it from my personal experiences. It has 13 mp back camera which takes crystal clear pictures and focuses well. It has wide selfie camera of 5mp. Except these it has dual sim 4G voLTE sim slot, a micr SD slot expendble to 64 gb. Its operated in new marsmellow operating system. But in the box there is no earphones in it and its battery is non-removable. But overall it has an elegant look with very smart design. The device comes with both black and white colours. No matter what phone we are talking about, there will always be something someone doesnot like.!
