The LG V20 is just a few days to its unveiling now and with the way that the LG G5 did in the market even though they had predicted good success for it, LG is not wishing to take any chances at all and they would be making a big splash when their latest flagship launches.
Already, the Nougat 7.0 is making a ripple in the water and they would be looking to other factors such as build and design to better appeal to the general populace.
As regards the most recent leak, the LG V20 would have a better and improved method for changing the battery and every other thing that is enclosed beneath the back casing because there is the possibility of a button on the side of the smartphone.
What the button does is act like a trigger to a slide out compartment and with a single touch, the back panel would open to reveal to you what should be a removable battery, SIM card slots and micro SD card ports too.
There are images and renders that are released alongside this leak to corroborate the information but to make things clear, the above is said to be an eyewitness account and so, you should take it with a pinch of salt because this might not necessarily be on the final design.
