I was using Samsung grand quattro for 1 year. But it started getting hanged n low in space as its internal was onli 8 gb. Then I was looking for a new phone . I like lenovo a6000 but that time Lenovo a6000 plus just got released. I liked the features Lenovo was giving compared to Samsung. It had 2 gb ram, 16 gb internal storage, 5 inch screen and Dolby sounds which Samsung doesn't provide u in any phones. Personally till now my phone never hanged . sometimes ran out of space but its good Lenovo gives u an option to transfer you're apps to SD card . the only thing I didn't like about Lenovo is that they haven't given update for marshmallow for Lenovo a6000 plus. It still has android 5.0.1 . other than than Lenovo provides u phones value for money.I love it. If u want a phone which is best n cheap. I recommend go for it. Lenovo is branded phone.
