It is boring to always use the auto mode in camera so let's try the manual mode and have greater quality pictures, which is better than auto mode.

What is manual mode ?
Manual mode is one of the main settings on your camera, and it lets you manually control shutter speed, white balance, manual focus, and ISO in most. These three settings work together to control the how bright or dark your photo is (known as exposure), as well as change the overall look of the image.

What is ISO ?
In photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain. Higher ISO settings are generally used in darker situations to get faster shutter speeds.

What is Shutter Speed ?
In photography, shutter speed or exposure time is the length of time when the film or digital sensor inside the camera is exposed to light, also when a camera's shutter is open when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time.

What is White balancing ?
White balancing is a process in which a camera will attempt to detect the type of white light largely visible in different environments. This is typically utilized to account for different light sources (fluorescent, incandescent, etc.), as well as different weather types and times of day (overcast, sunny, sunset, etc.). White balance generally focuses on collecting the proper temperature of white light in a scene, which ranges from cold (blue-tinted) to warm (orange or gold-tinted).

This is one setting that is often best left on automatic settings, unless the viewfinder suggests that the automatic white balance is obviously wrong. Of note, RAW images will have to be manually white balanced in post-processing, as RAW shooting will not modify the white balance in-camera.

What is Manual Focus ?
Manual focus controls are a more recent and much-appreciated addition to the control suite of manual smartphone photographers. Most camera apps features a simple and intuitive circular slider which can be used to accurately set focus manually in lieu of the jumpier and imperfect auto-focus, something which is often exaggerated when trying to take photos of close subjects. If you want to take a closer pic of something very near try macro focus.

What is Manual exposure ?
manual exposure is a small supplement to ISO and shutter speed settings, and it is one of the rarer manual settings one will find in smartphone camera applications. If a combination of shutter speed and ISO produce an unsatisfying image, manual exposure is often offered as a way of tweaking the brightness of an image in-camera. It can quite easily be replaced by simply modifying brightness after taking the photo, but it can sometimes be more efficient to get the image right the first time.

What do we have in our Lenovo P2 :
I had Camera api2 activated and snap camera hdr+ and oneplus 5 camera apps.
Shutter speed
Minimum 0.68s maximum 1/96423s
ISO
Minimum 100 Maximum 19200

Verdict approximate values
In low light condition
Higher ISO [ 500 ~ 19200 aprx] + Higher shutter speed [0.68 ~ 1/200 aprx]
In heavy light condition
Lower ISO [below 500 aprx] + Lower shutter speed [1/200s ~ 1/96423s aprx]

Camera Api2 advantages
Raw image capture support
In depth manual mode control

It's like this with all the camera apps that have avaible the raw format
At first I was thinking that the problem it's present because I usa a micro sd, but the image gets mad even without it.
I'm on the last lineage build by Higway Star

So it's a rom's related problem?
Same issue on stock s244, with every app.
Also, I've seen many others
Maybe due to changing roms in mobiles the camera driver can get into buggy, not confirmed yet.

If you want Camera with Raw capture try "snap camera HDR" with force HAL1 enabled in-app setting.

If you looking for completely manual configuration try camera api2 ON in-app setting.
