The bluetooth function is very weak, its virtually impossible to hear although the person on the other end of the phone says they can hear me. also the charger cable has failed so I now have to source a new one at great expense. Such a shame as its a great phone.

I think as far as like cheap displays are concerned with brightness tweaked low for desktop use, the blackview photos look a LOT better than the Sony or LG ones. Order of magnitude better. (they resemble the EOS much more)

Maybe if you have a HDR display calibrated then it's a different story.

The reason is that if I have my windows 7 system display adjusted so that 255,255,255 RGB in notepad and web and office doesn't look like "staring into the sun" but more like "staring at paper", the "better" images from the Sony actually end up being very dark.

Obviously this is a very difficult problem, one where OS and the display and ambient light sensors need to be in perfect co-operation ... to allow for Notepad white to look more paper white, while "sky white" on a photo open in another window is adjusted in a way that relates to the ambient light and approximation of how eyes have adjusted to the notepad white.

So the function for showing the image properly contains : ambient light, light emitted from display prior to showing image, estimated user adjustment to emitted and ambient light, photo to be loaded meta data about lighting conditions, the estimated emitted energy from most intense areas in the photo to be opened.

then all that is used to adjust the photo to open in such way that that the sun in the photo doesn't cause the notepad white to go invisible - so while the notepad (or web browser) is open, the photo actually needs to be shown suitable to that context. And then when photo is opened in full screen or some high end editor, it needs to be show with "HDR-dynamic range".


Another way of course is that you have 2 photos, one "mastered" for viewing side by side with notepad or web-white (255,255,255) but in this case the white in the photo ends up too dark unless because the function MUST account for the total white energy emission based on area function.

So if the photo is of a laser beam, it can be shown with more intense color that 255,255,255 without causing eyes to re-adjust unless you look at the laser beam directly in the photo.


The problem is best illustrated by question of "how do you reproduce how camera pointed at flashlight or laser should end up looking to the viewer of the photo". In typical case it won't look anything like the real situation but with HDR and 10 bit etc you can atleast try to go for a better approximation - yet how do you handle this when viewed with side by side with regular web content or notepads etc without causing "pumping" of the notepad white. This is why the function is probably quite complicated.

Philips has an OLED display which actually emits lights from the back of the display that change based on the content. Really clever because it recognizes the significance of the ambient light and eyes adjustment in relation to the emitted output.

QuoteThe Blackview P2 is equipped with current radio technology. It has fast Wi-Fi, although the manufacturer has given no detailed information about its specifications, and it has Bluetooth 4.1. It has integrated GPS which transmits on 2G, 3G and 4G frequencies as well as on the 800, 1800 and 2600 MHz radio spectrum. The LTE is supposed to be a cat. 6 standard with a maximum download rate of 300 MBit/s and 50 Mbit/s upload speed.

The Wi-Fi has good transfer rates in comparison to its competitors. Only the Oukitel could beat it. However, the speeds correspond more to the 802.11 n standard; the throughput would have to be a lot higher for ac. We therefore assume that the device is only equipped with an 802.11 n module.

You are completely misunderstanding my paragraph.
What I'm trying to show is:
You or who ever set the unit of (MBit/s) is applying a non-international-standard unit format for bit(b) and Byte(B). Therefore, Mbps and MBps should have been used as a standardization.
Enlighten yourself here: http://home.earthlink.net/~flatlinecs/id48.html

Why would you change from Megabit per second (Mbps) to MBit/s? There is absolutely no difference. First of, Megabit per second has to be Mbps. Secondly, if you are gonna convert from Megabit to Megabyte which you did by dividing the number to 8, which is 8 bit = 1 Byte; then YOU use MBps or MByte/s.
