Does a custom rom changes brightness level? - Xiaomi Mi A1 Questions & Answers

It might seems to be a stupid question. But with the stock pie rom the brightness level is lower than it was in Oreo which makes it almost unusable in direct sunlight. Does the custom roms use a different brightness level or not?

Is there a known issue for the ambient light sensor? (autobrightness?)

My light sensor does not work so my auto brightness has been no existent. I want to know if this is a known issue with Custom roms for 4.5.9.1 and the ambient light sensor. I am currently running R9 V5. Thank you.
Dont really know. My auto brightness gets stuck on high when i go from bright place to dark sometimes. Ive been leaving it on low for now. I have a friend who is anxiously waiting to dig into the kernel when gets his laptop running. I advise to leave it on low for now and manually put on high when used in sun. Im on a custom stock rom anxiously awaiting cyan7 and hoping little quirks such as this get ironed out or fixed.
I voided my warranty.
I guess the first question is whether this happened to you on a stock rom for 2.3.4. If not, then the problem may be your build.

Stock ICS brightness query

I have a tab 10.1 3G version. and i have tried both stock iCS and CM9and CM10 wen they came out. and i have observed few things.

I have tried ganbarou which is based on CM9 and also noticed this. While the lower brightness may be saving power I didn't really like the auto brightness settings, it was too dark and unreadable in many situations(basically any situation except dark room). So, my guess is Samsung limited the brightness to a reasonable values.
That's what I don't like in most custom roms, the devs are trying to squeeze the **** out of the devices, making them achieve amazing things but also making them pretty unpleasant for general use.
I'd prefer not to stress my eyes, instead of having +30mins of battery life.
cheers
The increased brightness range is better. The lower brightness is good for night time reading.

Brightness & color on stock vs CM11

Just wondering if it is only my device or others too. On my device, I have noticed that any stock rom or rom based on the 4.2.2 stock (for example Maladus rom) has a higher maximum brightness and more accurate color in comparison to any CM11 rom or rom based off the AOSP (including AOKP).
I have flashed multiple roms and all the roms based upon AOSP have the same effect; a warmer, less accurate color and a less maximum brightness whereas the stock rom or roms based upon the stock seem to be much brighter at say 80 or 90% brightness. In my case it feels as if the contrast or gamma has been bumped to a much higher value. Has anyone else ran into this issue?

Don't know about brightness, but color accuracy seems to be the same on both AOSP and stock.
It is somewhat warm but not too much, it really annoyed me at the beginning but I learned to live with it, it is not that bad

Vibration strength?

HI all,
I tend to buy a Redmi 2, however I wonder about vibration. Someone said that the vibration is too weak, but the reports seem old a little bit (with MIUI v6, I guest).
So could I ask if the vibration problem is fixed in currently firmware (MIUI V7 or CM13)? Or is it totally hardware problem and unfixable?
Many thanks
Redmi 2 has appreciable vibration strength( I am using at 50%,on a CM based ROM )
It have 3 vibration Intensity mode .. Light , Medium and Strong ..
But I think they ought to provide somewhere mid between Light and Medium , cause Medium feels more and light feels low .. allowing us to set Custom Value will be appreciated, that reminds me you can use Kernel Adiutor to Set the Value of vibration Intensity as much as you want ...

Screen brightness battery speed modded roms for this device are worse than stock ones

Hello, if you have noticed, every rom for this device, eui or not, are a @#¥%# besides the stock one. IM thinking about what kind of *optimization is done because in every rom i chequed the screen brightness is worse than stock, due to battery savings they say... Every kind of battery optimizations, power consumption kernel tweaks roms mods... BUT IF YOU TRY 26s install playstore the rom goes 100 percet fluid and goes very very well. including the ORIGINAL screen brightness problem that the people are complaining about, and better camera, and of course BETTER BATERY TIME. including all the chinese apps without debloat,, freecing it. SO If any of us start thinking about it and if not i will say my point. The modded roms for this device are collecting data from the user and selling it over other companies etc etc.
if you.dont believe me try yourself. i will very glad to liaten to your opinion.
cheers
my point is that the stock 26s rom is far far away better than any lineage or eui rom for this phone. including battery screen time speed of the device. screen brightness etc. Some of us are.complaining about.poor battery life. LAG and poor screen brightness. SO developers start tweaking the.rom. DECREASES the maximum brightness tweaks the kernel they said... and the result as.worse. INCLUDING roms with more that 20 or 90 versions.
if you think in a mobile phone there is ALL your life. SOMEONE could gain economical benefits from this if they collect all this information for whatever his needs are.
I HAVE THE.SAME SENSATION IN MORE THAN 5 DEVICES THAT I HAVE IN.THE.LAST YEAR.
And this.could not be a coincidence.
TRY by yourself the.stock rom 26s without any cook done, and tell.me your point. goodbye
Where do you find the 26s stock? In my opinion, besides the "less" performance of every custom rom, it has some advantages, I've been using a Chinese rom distribution for almost a year ( I had a huawei phone ) and it may work better, but I love the freedom "stock" android gives you, such as customization, better notification work, etc.
Stock rom or stock mod rom are slow for app installation, also brightness may be less bright and cannot get darker at night. Nougat roms give more brighness and can get darker at night. Stock rom 26S have eyes protection mode for use phone at night under Display, where Nougat have night light feature can turn on/off for use phone at night and speed as I mentioned like install apk file Nougat is flying where Stock rom is slower but optimized rom is acceptable.
This is good Nougat rom I am using maybe yoiu can try it:

This is true and false at the same time.
The stock roms have more brightness than CM lineage ROMs. BUT the developers, all, cut out the brightness yo save battery also performance, and the result is worse.
If you try the 26s stock ROM released in April/may you Will be pleased in terms of battery life, speed, stability and brightness, camera, etc etc etc.
The brightness with the stock rom is like an Iphone

I tried Stock 5.9.26S by ALBA in Russia forum, Stock 26S v5 by C.B.G, Small Eui v16 by Aurel latest, I found no significant difference to other rom or 5.9.23S, there was Google app/Google Play crashing issue at the start of 26S. Brightness is no issue for me even 30-40% indoor is plenty bright.
In small eui v16 you can have the same brightness configuration as a stock rom, also i've notice less ram but i dont care because i dont have too much apps open at the same time. I like this rom because i can customize everything with almost 0 bugs and good performance
