Well, its after a thorough(rather long) research, I have finalized on this mobile.
My criteria: 2 GB RAM(to accommodate decent apps as well as good response), good battery, sleek in design and handling as well as top notch Music.
I have figured out below devices for my parameters:
2 GB RAM: Lenovo A6000 Plus / Yu Yuphoria
Good battery: Yu phoria
Sleek design: Lenovo A6000 plus
Good music: Lenovo A6000 Plus
while the other factors on Lenovo was promising, its UI( I really dont like Vibe UI and its bloatware) and apprehensions on heating issues, I wished Redmi 1s could have 2 GB ram(I own a Redmi 1s as well:). Well, gods have answered me:)
Redmi 2 Prime turned out be a perfect answer for all of my above parameters.
After 3 days of usage, below are my observations:
Display - 10/10
Touch response - 10/10
UI - 9/10
Music - 10/10
Camera - 7/10
Speed - 9/10
Loud speakers - 9/10
Wifi signal strength - 6/10
Battery back up - 9/10
Performance - 9/10
Though most of it is highly appreciable, one downpoint I see is weak wifi signal. Keeping both Redmi 1s and Redmi 2 prime side by side, I could see 1 bar less on Redmi 2 prime. otherwise, no qualms. Hope any software upgrade would resovle this weak wifi issue
