Hi all! I'm having some brightness issues on my Razr i and any help would be great!
I'm on stock 4.1.2 and was using Power Toggles brightness slider to change the brightness, but suddenly, with no changes on the phone, the brigthness level would change only after turning screen off/on. But the problem is not related to the app I think, because even auto brightness isn't working properly... I mean, when it has to get brighter, it works, but when it has to dim, again only if I turn off/on the screen.
Does anyone know what could be causing it?
Thanks in advance!
Sorry for the bad english.

Although you don't think the app is causing the brightness problem's I would recommend uninstalling it for troubleshooting purposes and seeing if after you have uninstalled the app and rebooted the phone if after some time the problem persists. This way we can rule out if the app is or isn't causing the problem.

Thanks for the reply. I did uninstall it and the problem remains... I installed volume slider (which has a brightness slider too) and the same happens: non "real time" brightness changing and the auto brightness still doesn't work properly... =/

That is odd, I would recommend booting into recovery and performing a factory reset and then see if that fixes your problem.

This is what I was afraid of... =/
I will just wait a little longer to see if anybody faced this issue before. I'm pretty sure a factory reset will do (since it started to act like this all of a sudden) but I want to find the cause so it won't happen again or, if it happens, I won't need to do a factory reset...
It's weird... what could make this issue appear? =/

One possible way of figuring out what is causing this issue to happen is to generate a logcat when you are adjusting the brightness settings and see if the log reports any background processes that are causing errors with the brightness control.

Thanks for helping me!
I never generated a logcat before. So I installed CatLog from Store and generated a logcat doing the following:
1) Set brightness to auto
2) Put the phone under a lamp
3) Turned of all the lights: the brightness didn't change
4) Turned off and on the screen: when the screen turned on, the brightness was already on a lower level
The logcat is pretty messed... it shouldn't be like that right? =/
Is this helpful?

From looking at the logcat there is a lot of errors and warning messages with loading certain library files and Android runtime services that relate to power and screen brightness sensing. Another peculiar thing I noticed was that NFC seemed to be generating a couple error messages as well. Overall you were definitely right about it not being a normal log in this situation, I also like your testing methodology :good:.

You could also try re-flashing the stock ROM to see if that fixes it, another suggestion that could possibly work is running a fix permissions utlity.
Reflashed stock rom and reinstalled all my apps. Everything was fine. Went to bed and woke up, the same problem with power toggles reappeared...
EDIT: found what was causing it! It is the latest version of Floating Notifications (when show on lockscreen is enabled)!
Thanks a lot shimp!

That's wicked bizarre that even after all those things the problem still persists. You could try bringing it in to Verizon to see if they can do anything otherwise a hardware issue may have arisen.

When I unlock the phone it always starts up very dim and sometimes it turns bright sometimes it doesn't. I have auto-brightness off and I have my brightness set to 100%. I have to move the slider off of 100% and back to 100% to get it that bright. It is very weird. Anybody know how to fix this?
I have the same problem.

Is it dim on the home screen or certain apps? cuz internet browser, video etc got their own brightness settings built in that you have to change from the settings within the app.

It is dim from the lock screen. Everything once I unlock it is dim. If I lock and unlock the phone like 3 times fast it is fine, but it's a pain in the ass. I'll see if I can take a video of it later when I get home.
I know you said "everything" but try to go to internet browser and disable "auto-brightness" under brightness setting.
Also upgrade your firmware to the latest one to see if that help. My Smart detect is not working and after upgraded it work every single time plus the cell stand by is much improved
I just got my phone back from service, they updated to LF5 - so far it has solved my proplems with dim
I have had 2 handsets that do this now. Its really annoying especially when you are outside.
Basically what is happening is that when your screen dims down before it goes off thats what is happening when you unlock the phone.
I can be using it for 5-10 secs before the full brightness kicks in.
It has nothing to do with power saver or internet. Just running through the home pages and apps list it is doing it.
I am on the latest firmware too.
Does anyone know whats causing it? Is it just a faulty handset (or 2)?
Mine the same. I don't think there bad devices I think its just software related tbh

Well im glad some others of you have experianced this also.
I just hope its something that will be fixed in an update.
It really p****s me off when it does it and im outdoors.
For some reason I see the brightness changes automatically in certain apps.
The auto brightness is off and set to full.
The brightness dims in the following screens:
1. Open original browser it dims , if entering web address it is back to full. Chrome does not encounter same problem
2. Original samsung mail app (not GMAIL) dims. If writing a new mail (reply/forward) it goes back up.
The brightness in the browser settings is set to full (not auto).
I tried to find an answer on the web but could not find. It drives me crazy!!!
Must say that I have the phone for 3 months and it started only a few days ago.
the only thing I can remember is that I was on WIFI and it started to update apps but how can I know what was changed and [email protected]#$ed my brightness control?
I assume that you're using a stock (or stock-based) ROM. Try to enter settings and deactivate the power saving mode if it's enabled. Then reboot - just to be sure - and look if the issue is gone.
Can't think of anything else at the moment...
Hope it helps
In stock browser disable auto brightness setting.

I can't believe I missed it. I've tried brightness in stock browser, tried battery saving from brightness menu.
I just didn't notice the toggle of battery saving in the main menu.
Thanks...
Hah, nice to hear that youe problem has been solved
Hey,
Updated from 4.2 to 4.3 hoping it was a glitch with 4.2 but my screen brightness flickers up and down what appears to be about 5 levels consistently (very fast, resembles a flickering) whenever the display is on. The brightness control also doesn't work, it has no effect on the brightness levels, you can slide it from one side to the other with no actual change.
This has an ill affect of draining the battery about 1% a minute when the display is on.
Anyone have a similar problem or know how to fix this?
I have the auto brightness unchecked and when enabled there is no change either.

When you flashed to 4.3 did you do a wipe? Have you tried a reset at any time? If you just updated without wipe it would have retained any previous settings or conflicts that may cause this.

I'll do a quick backup and then try a wipe to see if that clears it up. Thanks for the suggestion.
maybe you has to sent to service central but before just update again ,hope will fine
Did all the wipes and no go, called up Bell and have her going in for a RMA check. Can't wait to see what they say.

Are you sure you flashed the device correctly and followed the procedures in LordManhattan's guide or [NUT]/blueether's posts?
I've noticed that no matter what setting I have it on, my tablet (M5 8.4) automatically lowers the screen brightness in Chrome and YouTube, but more noticeably in Chrome.
Any way to disable this?
Have you checked the setting menus?
Using Firefox might be a solution.
Also, Youtube in FF has background playback as long as you are using a desktop user agent.

I've checked every possible setting, and read online everywhere, but to no avail. It also dims in Firefox. It dims as soon as you go into the app. After an online search, I found many Huawei owners with EMUI 8.0 having this issue. There is one solution, but it requires root and I don't want to root my device after having it for a few hours.
Funny. Would love a solution as well as this is rather annoying
Do you guys have auto brightness turned on or off?
I never really experienced this issue, but I did observe strange brightness behavior before I began to keep auto brightness permanently enabled.
Doing a quick search, I saw one person say to turn auto brightness on, I saw one person say to make sure animations aren't disabled in dev options, some say unclick 'increase readability in sunlight' in dev options. I personally wonder if the stock launcher (which I don't use) maybe is set to override the brightness level.

I somehow doubt that. I am using Nova Pro and am experiencing some weird behavior when attached to the Keyboard ... (the dimming function mentioned here is, what I believe, the erroneous function, as it works quite nice when not attached to the keyboard ...
All "your" suggestions do not work - I find this "function" somewhat annoying, even without the keyboard-thing ...

Well, I went through with it and rooted it. I tried the fix, and... it worked! After you're rooted, simply freeze the system process (I used Titanium Backup) called PowerGenius, reboot and no more forced-auto brightness dimming.

Just disable "power genius" this has worked for me. without root. No More auto dimming.
Disabling Power Genius will also get rid of issues involving bluetooth music playback, and will prevent apps like Google Maps from getting killed off semi-aggressively in the background (i.e. so when you map out driving directions you won't have to reenter the address as you get close to your destination).
Quick note: you have to reboot after disabling Power Genius. Merely disabling it won't immediately change anything.
Up until now I thought a reboot would bring the "wonderful" feature back ...
How comes that you mention a reboot is needed?
How do you disable it? I can only do a force stop
I'm not sure how to disable it without root (I imagine adb might work). With root, most use Titanium Backup to freeze it. I'm using Service Disabler to disable the associated services instead. Service Disabler is awesome if you are rooted, underrated app and great for EMUI because, for example, you can disable individual parts of the Tablet Manager app without breaking the features you want.
You might not need to reboot. When I initially froze it using Xposed Edge Pro, but didn't reboot, it didn't change anything for me. Could have been due to Xposed Edge Pro.

I can confirm following the above article will allow you to remove the power genius package from the Mediapad M5 8.4 on EUMI 9.1 without root.
Thank you sooooo much... You can't believe how annoying this was. No need to even reboot either and it doesn't return if you do.
Now I just need a way to too keep the custom 740DPI after reboot and this tablet will be perfect
I turned off adaptive brightness, but while manual brightness is set to maximum I noticed the screen also increases/decreases brightness depending on the outdoor conditions. Sometimes seems it gets even brighter that max manual setting.
Anyone else experienced this?
Hi @mejgs
I too had this annoying issue. Apparently this is caused by an app called "Device Health Services". Disabling it solved the issue for me. Do give it a try & let us know your observation
I noticed it too. Did u experience any issue when disabling it? I am rooting, thinking of uninstalling it altogether. Google has some unwanted apps bundled with Android one.

Disabled it, still the same issue. So far tried:
- Turned off adaptive brightness, rebooted
- Turned off adaptive battery, rebooted
- Disabled Device Health check, rebooted
- A combination of above
Still nothing!
It's getting beyond irritating now. Everytime I need to read any message or do anything on the phone need to manually lower the brightness and increase it again. That normalizes it for a like half a minute and then goes dim again.
Same issue with my Mi A3 and adaptive auto brightness.
I keep adaptive brightness on all time and when I unlock directly with fingerprint sensor half of the times if not more phone wakes up with high brightness...and doesn't go down...slider is on the dark side and not showing the real brightness...and to change the brightness I have to move around the slider...
It is quite annoying..I disabled device health and seems slightly better but the bug is still there...am I the only one with this problem?
I don't think its a bug but rather a way for the optical in-display fingerprint to properly recognize our fingerprints.
