Scratching head for days, may be you guys had more idea than me.
Google Now is on, Google Location Reporting off, location mode = Battery saving. I always go sleep with Wifi off and 2G radio only.

I notice Apple like sapphire glass a lot.
First it was their camera lens on the i5, followed by the fingerprint scanner on the 5S.

Maybe 'cause Apple is using it, then everyone thinks ZOMG! APPLE ISH USING IT!!! MUST BE BESTTT!!!!

I think eventually DiGi will use both band 3 & 7 too.
Speaking of DiGi's LTE, where the heck is the LTE service for mobile phone???
I've owned 3 devices with front facing camera but never used in in any application.

The odd thing is larger number of Googlers are photography nerds. I wonder why with such interest Google keep releasing Nexus devices with low performing cameras...
I don't expect Android OEM's to release a device that beat Lumia 1020. But at least make a camera that is perform consistently good.

Finally I received the rhino sp, surprisingly even do the sp abit thick it doesn't feel like i applying any sp on it 

many ppl being mislead with those camera manufacturer that playing the psychology with more megapixel mean better photos quality.

in actual, it does not mean so, unless you are a person that always want to crop the photo you take or you want to print a photo at the actual size of that large megapixel you take.

if you view a photo on a Full HD monitor which hv the maximum resolution of 1080 x 1920, a 2MP photo already more than the monitor can show at 100%.
so, even you view a 16MP photo on a Full HD monitor, you still have the same quality as viewing a 2MP photo.
As that is the max the monitor can display.
Unless you have the Ultra HD with 4K resolution of 2160 x 3840 then maybe you need at least 10MP to fully utilize the screen.

stormlcc also mentioned that the size is the main concern with more megapixel. the more megapixel you have with your camera, the bigger the file size.
the bigger the file size mean bigger storage you need and the more time you need to load the photo.

why waste storage, loading time for more megapixel photo that you mostly will only view on yr HP or even on yr TV or PC monitor that is only Full HD size?

Just try to reinterpret your words. 
Prefer sensor size over megapixel.
Lumia 1020 had significantly larger sensor than average smartphone, then DC, DSLR, full frame, medium format blah blah blah . . . .

Alright here are the partial results of my attempt at the white accent on the sgp hybrid buttons.. still have to clean it and apply on those little spots..
