due to largely commented problem of many chinese smartphone fake dual lens cameras, i would like to obtain a clarifying technical explanation from UMIDIGI, how actually we can know if this dual lens camera has really any fonction? as per testing videos available on youtube, the bokeh-effect is a software effect, i.e. focus is centered and all around is blurred. a real dual lens camera allows the user to freely chose which area on the picture he wants to have in focus and the background blurring level also can be adjusted directly on the screen before shooting the picture.

can somebody from UMIDIGI explain and/or confirm that this is/will be possible on UMIDIGI S2 PRO camera ??

well, thisone goes to the administrators (e.g. http://community.umidigi.com/space-uid-242063.html) of the forum, hopefully they will pay attention and transmit to the UMIDIGI developers.
there are at least 2 major companies which supply the necessary knowhow and corresponding applications for dual lens camera cellphones:
- corephotonics
- arcsoft

coresoftonic on its website has an excellent demonstration how a real bokeh/portrait picture looks like, here it is:
http://corephotonics.com/products/digital-bokeh/
specially when you click on "far focus" it shows clearly the girl's face and body neat, but the foreground (her hand) and the background get gradually blurred,
exactly like on a portrait picture taken with a telelens on a SLR-camera!

arcsoft has also the necessary knowhow but they do not show samples on their website, only general information and for more details you can contact them:
http://www.arcsoft.com/product/d ... on-smart-phone.html

so, as UMIDIGI says they use one lens 13MP and the secondary lens 5MP both together would clearly allow to take real portrait/bokeh pictures, the 13MP camera
takes the main shot and in focus, while the 5MP takes a slightly different angle view based on which a "depht of field" calculation can be made by the software
and then produce the portrait/bokeh picture with less or more blurring of fore- and background.
that's the way how it should be done.

so please ADMINISTRATORS: CONTACT THE PHONE'S DEVELOPERS AND TELL THEM THAT THE STOCK CAMERA APP SHOULD BE IMPROVED WITH A CORRECT
BOKEH TECHNOLOGY.

if that will not happen it would mean that the 5MP lens is fake and has absolutely no function. so IF IT IS FUNCTIONAL, there is absolutely no reason not to include
a corresponding software update!

thanks for your attention administrators. i look very much forward to your feedback and hopefully a quick update in this sense of the camera software.

This is the best explanation ive seen yet,if Umi is telling the truth and the second camera is functional they can update it. Administrators just answer certain posts, Ill not be surprise if they dont  Post time 2018-1-22 05:18

On the video "Umidigi S2 Pro disassembly after soaking in water", at 1:04, we can see the connection ...

Hi
Second camera is focusing background (depth of field) also increasing light coming to sensor. This feature is fixed that why is no adjustment and never will be because hardware can't support this. Bokeh effect is working correctly at bright condition and up to 2 metres from object.

In every dual camera bokeh effect is done by system.
Only Umidigi Z Pro got two cameras on back of phone which both could be used to take real pictures. One camera was used to taking coloured pictures and second for black & white pictures.
In other Umidigi devices with dual camera on back of phone one is used to take real pictures and second is also real camera unit but is not used for taking pictures,  only to support first camera with higher amount of light coming to sensor especially in darker conditions and to focus background only in certain conditions.
This setup is increasing pictures quality taken at darker conditions.

Of course you can take picture in bokeh effect focused on any object you want only you need point on screen place where you want focus and adjust bokeh effect

but this is from Umidigi Z dual lens camera .... what I want to know is : has UMIDIGI S2 Pro the same feature, i.e. you chose freely where the focus point is and background blur amount? like on model Z ??

Hi
Yes I can fully confirm that camera app is exactly the same with same options and same bokeh effect.

hi
I have a Umi Crystal and I can not get good pictures with it.
I tested several applications, since the original delivered only 9mpix (for a dual sensor 13 + 5B & W mpix) it is ... light.
Is there an update planned to improve this tool?
My Umi Super took a lot more beautiful.
If there is a solution, it will be welcome
Thank you in advance.

Another thing, an update to Android 8 is planned, because of forul talks about an existing version for the Crystal?

ok thanks for confirmation.
BUT: after having had a closer look to your image showing the bokeh effect configuration on the model Z, i found it strange that the area where the focus points is kind of exactly the same round shape where image appears neat and in focus but then all around is blurred, which looks about same as the fake bokeh effect on other cameras except that it is not centered but freely placed within the image. can you actually show some sample pictures taken with that Z model or even better: with the S2 Pro ? would very much appreciate.

please check the configuration of your picture size: the 13 mp are for standard picture size 4:3, while the 16:9 ratio (larger surface) results in 9 mp !

Both phones contain same design camera app but of course with different features and different options etc.
