I received today my new A119. It has the hot pixels issue, bright pixels when it is dark. According to what I read, wasn't it supposed to be fixed in production units?

Anyway, I tried to do that calibration thing in engineering mode, but the explanation of how to enter this mode didn't work. When I created that file the only difference was that the camera didn't automatically start to record, but there wasn't any additional options in the menu. Did I miss anything?

I received the camera with firmware version 160829 installed. How can I fix it?
 
EDIT: NVM I was wrong

Ok I was wrong. I checked again, there was just a different menu in that version, there is still a simpler version in newer firmwares. I still can't get into that mode.

That is really weird. It reacts to that file but doesn't enter engineering mode...

EDIT: The problem seems to be more serious when recording in 1080p60 than 1440p30, but maybe because the down scaling on my 1080p monitor.

2nd EDIT: After deeper inspection it seems that I was correct, the only firmware that had this menu is 160418.V1, but I still can't get into that menu for some reason...

I did downgrade, but don't working engmode. The developer is not responding.
 
We will check the old firmware which support engmode.
 
Still not able to enter the menu (I am 100% sure that I created the file as required). Is anyone able to enter this menu with a new camera?
 
I also discovered tonight that I have hot pixels in all recording modes except 1440P. Have 7 pixels that at night look like stars in the sky. I probably never would have noticed except that I was comparing if any difference in night time recording between 1440P and 1080P. Thread is located here:

Not a big deal but if there is a way to correct it I would like to know.

I tried and could not enter Engineering mode. I tried with firmware versions 08/29, 06/07 and 03/05. 🙁

Ok, I give up. I was able to enter the menu but I wasn't able to fix the hot pixels. I will just stick to 1440p30 for now (I wanted to use 1080p60)
I only have one hot pixel in 1440p30 (at least when I watching it on 1080p screen)

So here is how I entered the menu. after leaving the camera off for a day and turning it on it suddenly did enter that menu (with the 01/03 firmware). But anyway it was very not consistent.

So because it is so hard to enter that menu (at least for me) I modified those firmwares in such a way that the menu will be opened when pressing the emergency button on the main screen (after you exit the choosing language menu) if engmode file exists on the sd.
Here are the modified firmwares (I think that you should use the newer, 18/04, because it has little bit different menu).
Just a word of warning. Even if those firmwares are bad it shouldn't brick your camera because it is unbrickable as long as you don't mess with the loader, so even if a firmware upgrade fails you will still be able to upgrade firmware. but still,
USE AT YOUR OWN RISK.
18/04
01/03

Anyway, the menu doesn't behave as described in the instructions. I was only able to do DP Bright and not DP Dark (it always fail, no matter what I do).
But just a warning, if you do a bad calibration, the issue may get worst, but calibrating again correctly should fix it.
At one point I thought that I got rid of the hot pixels, but than I upgraded back to the newest firmware and they were back again, at the same spots...

If someone was able to fix it, please share exactly what you did.
