I own Nexus 5 after having great experience with this product, my brother bought LG Nexus 5X for Rs. 32, 000. I am sharing my experience with this device.
The things I liked:
The things I didnt like:
2 GB RAM when other new device offer 3 GB RAM.
Optical Image Stabilization is missing
No storage expansion
too expensive
pay extra to connect to your computer. USB type C is new standard for android devices.
I had good experience with nexus 5 and so my brother opt for nexus 5X. Device is overall good but as mentioned above few things are not as expected for this budget. The battery life of phone is good. Phone does not lag. This flagship has built in Marshmallow 6.0 version. No heating problem when used for hours and hours.
I would recommend this flagship if you are ok with 2 GB RAM and good budget. 2 GB RAM is perfectly ok but nowadays there are other flagship coming in the market with 3 GB RAM. I hope you get my point.
