[TESTING]LCD panel improvements

Hey ho fellas ,
I was working on adding power management + initialisation/de-initialisation sequence for rhodium´s lcd panel. Till now rhodium´s panel was always on ( initialised ) in deep-sleep aswell those meaning that the display was never de-initialised and was consuming more battery then normal.
I would like that all of you users that are willing to help to test the kernel ( zImage+modules + latest commits included ) and give some feedback.
Test the power on/off sequence, leave it sleeping for ~30mins and unlock it,...then give me here some feedback on your lcd panel behaviour.
zImage + modules ( mediafire or attachment ):
http://www.mediafire.com/?ny18wpc3z8utxrf
Prerequisites:
- Backup your data.img if you have some valuable data on it ( anyway it should not affect it )
- Delete pm_sleep cmd from your startup.txt

What do you mean by this?

Do you mean that although the display is off, the panel is still on? Or am I getting this the wrong way? If you could explain this to me then I am willing to test

I think that even though it looks like the screen is turned off it still draws power, so this should eliminate that issue allowing better battery life

Yea the way it was explained to me (by the OP on IRC) is that you can't really tell necessairly that the panel isn't being properly de-initialized... I questioned that at first as well.
I played with the new zImage, seems pretty smooth. Had a few hiccups on wakeup, but nothing crazy. Test it out guys, let the OP know how it worked!!

Does it matter for the testing if you use pm sleep 2 or 1? Just curious. Testing now

It would better that pm_sleep has the default value.

Will give this a try as I go about my day today. I don't OC and use pm_sleep=1 yet still get terrible battery life (b/c I'm a power-user, on e-mail constantly). Any positive change will be wonderful We'll see how it goes.

My findings:
- Device does not go into standby, but I used sleep 2, maybe that is the cause.
- The Led keeps blinkin red. (never seen that before on android)
- The device reboots itself.
and a really negative effect is that I lost all my settings... My launcher pro settings, setcpu, whatsapp...

Hi,
As far as i understood there is no way to know exactly is display in standby mode or not?
I did some tests for now with light sensor ON and OFF (in WM) so here we go (PM is set to 2).
With sensor turned ON in WM:
After going standby screen gone completely off, no glow from backlight in dark environment like it was in previeous kernels and here is an answer to my guess above, screen IS truly going into standby. Also I've noticed some strange behaviour, the debugging led which was intended to go green in standby, randomly (i guess) flashes in around 2 Hz frequency with amber and then stays for 3-4 secs and cycleing like this, no green at all. Returning from standby is not OK, after pressing end button screen is not turning on as expected BUT, after touching at the place where unlock or mute sliders should be screen wakes, so i can assume that after pressing end button screen is just not turning on but touch panel does. Wake on call works as before, as like as wake from HWkeyboard slide (both with 2-3 sec delay). Shutdown actually turn the phone OFF.
It seems With sensor turned OFF in WM, phone acts same way.
I was testing with Matthew's RAR - Android v2.2 Froyo: BLAZN from Aug 30, 2010

1. Try deleting pm_sleep from your startup.txt ( then the default value will be used - i recommend that ) or put 1
2. never seen that on android
Anyway i am really sry for the inconvenience regarding launcer pro, kernel change should not affect those kind of settings :s

Yeah its a common problem for now we are investigating this.
So i have a confirmation that the screen is really powered off?
Anyway guys try putting 1 into pm_sleep or deleting it from startup.txt (i recommend the 2nd choice ).

I ran into an interesting problem however I did not see the previous post...
Several time it went into standby (I assume) and the screen was pitch black meaning the backlight was not on. To get it out of standby, I woul click the end button like normal. after a couple of hours I pulled the phone out of my holdster, and it was abnormally hot. I do not have an overclock and my pm sleep is set to 1. I did not press the screen to see if it would respond so maybe that is what was being mentioned in the last post. None of the buttons would bring it back to life and the LED was amber and solid, where typically it would flash with this new zimage and modules. I will try to get it back to that state and see if I can click the screen even though it is dark. One thing that worries me is the battery though. Could this be damaging to it? Even when I did have it overclocked it never reached that temperature.
Anything else I can do to help troubleshoot?
EDIT: Sorry, forgot to mention I am on a Sprint RHOD400

I'm on the RHOD400 model, no OC, pm_sleep=1
Couldn't really get it to be stable, had to switch back to WinMo for the day (and trust me, that's desperation ). Once restarted in my pocket without any interaction on my part. I would press the end key to turn on screen, and had it auto reboot at that point as well. Also got a "sleep of death" twice and had to restart. While in your kernel I didn't have notification LEDs as well (not even for power events), vs the guy above that had blinking red.
I'm sure you'll get it eventually, keep up the hard work!

Hi!
Any news? Are we gonna wait for new kernel with committed code or it development is stalled?

[Q] mmuzzy 4.2.1 and screen dimming

I installed mmuzzy 4.2.1 ROM on my phone and have been quite happy with it. The only problem I have is that the screen dims after about 30 seconds and I can't find a brightness setting that will allow me to disable this feature. Does anyone have a way to turn this off?

settings -> display -> sleep (not sure if that is what you want as you've probably seen it). I don't think there is a setting to stop it from dimming before turning off. Increasing the time to off keeps it from dimming as soon.

Sorry, not good enough

I want the dimming off completely.
I turned the developer options on and told to leave the screen on when charging. But it still dims. Once it dims, it's impossible to see the screen while in the car. 4.1 never dimmed. I may go back to the 4.1, since this seriously impacts my ability to use the phone in my car.

You might be able to set up a tasker profile to keep the screen on in the car. I've done that in the past for use in the car. I would guess that this feature is at the kernel level, so you could try a different kernel.

I'm just rolling back to 4.1. 4.2.1 didn't buy me anything feature-wise.

It seems someone has files a bug for this

If people could please star this issue, I would really appreicate it. I have a Nexus 10 now, and don't have an option to roll back to 4.1 and this is really annoying.

Ambient Mode?

I see a few posts here (and other places) mentioning an Ambient Mode.
I cannot find anything in the User Guide about it and I do not see any settings for it.
I am on: Android 6.0.1 - android Wear 1.4.0.2621048
(On a Zenwatch MSQWI500Q Build # MEC23S)
There is an Always on Screen, but it does not do anything.
I just noticed in the Asus Zenwatch Manager - the Face Settings - Dim Screen after - Never; does work.

It has always worked okay on mine. It does turn off after a while if you set it down or put it in to charge, but it stays on while wearing it.

When I try to update on my Zenwatch (Settings - about - system updates - it says it is up to date
My Note 4 has AndroidWear 1.5.0.2951640.gms on it
I will try searching to see any way to force this
Maybe unpair - then reset my zenwatch?
It is only a week old (for me - I bought it "refurb")

Hmm. Resetting is worth a try, since there's not really a downside. I also found this, which might help: http://forum.xda-developers.com/zen...-zenwatch-manager-facer-t3334255#post65815338

Thanks - I will give that idea a try
I have no setting anywhere for a reset <-- Ahh I just found it!
It is called Unpair with phone in settings
It says "unpair & factory reset" when I tap on Unpair

I did manage to get it to update after a good bit of tinkering (unpairing - old versions of Android Wear <-- That did not work for me)
Anyway I now have:
Android Wear 1.5.0.2884951
Build Number MWD48B
I still have no Setting about ambient mode - but at least I am updated Thank You!
It seems to be just a bit smoother now too.

I have searched all over and cannot find ANYTHING that tells how to get ambient mode "on".
I tried a few of the Watch Faces in Asus's Zenwatch app also to see if any had some settings
I wonder if it is something that Google Dropped in 6.0.1 ?

I think maybe the term "ambient mode" is specific to the Moto 360, but I think it's sometimes also used by people to refer to the dim mode of the "Screen always on" option. Will your screen still not stay on all the time with that option on?

If I just set Screen Always on - on my Zenwatch - it goes off in a few seconds (actually to the time set in the Zenwatch Manager App on my Phone)
If I set "Dim screen after" on my phone in Zenwatch Manager App to never, it seems like it will just stay on all the time (My guess is battery would not last long that way)!
I am at almost 20 minutes now and still in full color.
I just layed the Zenwatch on dy desk so I did not wake it up by moving around.
I set it to 30 secound and in apx 30 seconds it goes black/off

With screen always on, the normal behavior is that it's full-color for 8 seconds (I think), then it goes to dim mode, which is just pure black and white on most faces. Using WatchMaker, I have mine set to 10 seconds. The battery on my ZenWatch still lasts about 2 days with screen always on, though I still charge it every night anyway. Try uninstalling ZenWatch Manager. It's not really necessary. I don't have it installed.

Well I uninstalled Zenwatch Manager - installed Watchmaker - picked the first face Steel Blue - Just Digits
Set "Keep Watch Awake" to 10 seconds
And it still goes off in the 10 seconds.
I even rebooted my Phone and my Zenwatch same
What about some setting in Android Wear?
Only one I see is Always On Screen slide switch it is set to on - but setting it to off does not change the way it works

Yeah, the only thing I have is "Always-on screen," too. I have it, and "Tilt to wake screen" both set to on. I'm at a loss at this point. It seems likely it's a software problem of some kind, but I don't know where to look next.

Well thank you for trying to Help!
I appreciate it!
I just noticed something interesting:
If I set Always On Screen on my Zenwatch: When it goes to sleep (so to say): It first goes dim then it goes black and white. - But then it goes off.
If I have Always On Screen off: It just Goes DIm then off
So my take on mine is it is a glitch of a defect.
I will probably live with it as I bought it as Refurbished

Hi!
I have exactly the same problem ! But it came after updating my zenwatch to 6.0.1 (M1D63K) .
Have you found a solution?

I'm on the same boat. Always On Display is activated, tried doing it on the watch, on the Wear App and the ZenWatch manager. No luck. I've received OTA updates regularly, but none have worked.
I'm posting in the hopes of finding a solution. I've had this watch way beyond the warranty period, so there's no way I'll be able to return it to Asus.

Was a solution ever found? i am now experiencing this problem after owning the watch for 2 years. It has never happen before.

screen sleep issue

So let me know if you have the same issue... No matter how long I set my screen off time for, it always goes go sleep after 10 seconds!

Don't have that issue here. ATT version

I do not have that issue either (AT&T). Perhaps there is an email account or other "administrator" that requires a short screen timeout? I have seen that before.

The main screen. I turned moto display off and it still happens

I ever tried rebooting into safe mode and same problem.. Going to try a factory reset later

My motoz2 is doing this same thing. And it is frustrating. (Verizon). Have you figured out how to fix this?

Do you have adaptive brightness turned on?
Sent from my Moto Z (2) using Tapatalk

So I did a master reset and didn't connect my tumi battery until the play store updated the moto mod app to the newest version.. No more screen issue! I highly recommend anyone who gets this phone, update the app first before you attach any type of mod.

Redmi Note 8 Pro Screen Calibration (warm temperature)

Hi,
I received my RN8 Pro just yesterday (22nd Oct) (India).
The first thing I noticed is the screen quality.
I find the screen is calibrated a tad bit warmer than usual. Even if you go to the screen settings and tweak it to 'cool', it still remains yellowish.
I came from OnePlus5, which had an AMOLED screen (not fHD/SuperAmoled). There the screen was obviously more crisp, I don't really expect that here. However, the calibration looks bit different if I hold these 2 phones side by side.
What I want to know is, is this just my RN8 Pro, or others also feel the same?
Also, in MIUI where is the 'night light' setting, where I can either manually or automatically turn the screen hue warmer? It's one of the main features in OxygenOS. Actually, the current RN8P calibration looks like 'night light' is already set.
Issue summary:
1) Daytime screen temp looks like as if the 'night mode'/'night light' is already ON. (Note, I don't mean 'reading mode', that's different)
2) Night time screen temp gets very yellowish, almost as if the 'reading mode' is on
3) Screen calibration (warm/default/cool) doesn't change it a lot
4) Can not find the setting to turn off the 'night mode' in #1
Thanks.

In RN8P you can find Night Light in "Reading Mode" in Display option, it turns the screen hue warmer. I'm not sure about the warm color. May "Reading mode" is enabled which is causing this. Try to check that option.

I feel it's not all the time, it's mostly at night. Will compare again now. I got it yesterday afternoon.

Yes. And there is no quick way to disable the night time extra yellow tint.

You think it would be eligible for a replacement?

If you could compare it to another rn8 pro and see an obvious difference then yes you should claim for warranty.

If I find mine is an exceptional issue, I'll try to get it replaced, though I feel that may not exactly come under their replacement policy.

Try enabling and disabling it. turn off schedule option if it is enabled.
Check whether night light settings are there in developer option or not

Tried all the enable disable combinations, set as disabled right now, can say it works or not only after the sunset.

It's 10 pm for me, I hope someone else having phone confirm this too.

Looks like mine got fixed on its own. No more automated yellow tint.
Possibility#1: Xiaomi pushed some OTA
Possibility#2: I forcedly changed the 'good night read' schedule to some random time. 'ON' from 11pm to 1am, and kept the scheduler 'ON'. So, it didn't turn yellow at 6pm (the approx sunset time). Once it's past 6, I turned off everything there. It didn't turn yellow. Rebooted. Didn't turn yellow. Will observe again tomorrow.
