USB OTG allows your phone switch from device to host mode, or vice versa. Therefore your phone is able to receive/send data if any USB device like pendrive or HDD is plugged in

Perhaps his 10k extra charging times is a misleading figure, nevertheless, his argument is correct where frequent charging of battery improve the life cycle of battery.

i see that the front facing camera is only 1.3mp which is probably not 1080/720p @ 30 fps. So does it affect much on video calling?...as in the person on the other side look at you like a robot talking to them.

1.9mp so what? The MP for front camera is only important for camwhore 
For video, they're both 720p 

i see,.

I ask because some of the reviews are like, 2 weeks earlier than the release date,

and its not possible that they bought it normally right?

thanks ya'll

they not only get the device, they get paid to review it too

Oh, so now you are comparing between reviewers and newspapers in terms of generating money? Lmao. Those are two different things. Newspaper are solely dependent on advertisements and sponsors. Online reviewers may be bias towards certain preference of brands but do you have any proof that they are being paid by the manufacturers themselves to review their products? Justify your claim. What I am trying to imply is that, not every reviewers are being paid to reviews products. You understand the meaning of, NOT EVERY?

From what I know, most of they were given the devices before the public, to provide an in-depth review of the product which allows customers to be aware of it's pro's and cons before they make up their mind as the repertoire of smartphones are pretty big. Individual blogs are another issue. Why are you comparing between a website who generates an average of 1000 views a day against one that has only 100 (popular bloggers) on average per day? A little common sense please.

some are to troubled to carry a power bank. it will cause them backpain due to excessive weight.

I warn you. Once into android, if you're more enthusiast type, there's no road for you to return to iOS. I started with Android then I find iOS so boring 
Give me iPad to play I don't know what to buy besides those games.
For those who like simple and straight approach, go for Apple. They limit how you use your phone. Android let you customize most thing to your preference.

if the wireless charging required the phone contact with the pad then i don't see it as a practical accessories, at least u still can maneuver the phone around with cable.

plastic isn't necessary a bad thing, HOX dual shot plastic molding with softer material at exterior is nice.
