I'm facing an issue with screen wake up with my kenzo in Nougat 7.1.x roms. The screen takes more than a second to wake up, and the issue occurs both while using the fingerprint scanner as well as using the power button to wake. On succesful scan/power button press, the button backlights come on immediately, but the screen comes on only after a second, and sometimes even more.
This issue was also present till MIUI 8.0.6.0, but was resolved in the MIUI 8.1.1.0 update. I also tried Xiaomi EU rom and it did not exhibit the issue at all.
I know a mere one second delay is not something to rant about, but still it gives the perception of a cheap underpowered phone, despite having one of the most powerful SOCs around. The fingerprint scanner is really quick and this issue doesn't do justice to it.
What can I do to speed up the screen wake up in custom ROMs?
P.S: I use Radon kernel in all the custom ROMs that I flash. Anything to do with that? And, please DON'T suggest me to go and stick with MIUI!!
Regarding Radon. Which version did you use? I think it was 3.7 were they changed something that slowed down the wake up. It should be fixed now in 3.8
If you're using 3.8, let the developer know they may be able to sort it out.

I've been using Radon right from version 3.7.4, and am now on 3.8. I have tried wakeup boost as well, and noticed no real difference.

Wake up boost doesn't do anything for me either. Have you adjusted any other settings, like minimum frequency? It could be that too. I'd reflash the kernel, set balanced profile and don't touch anything in KA (maybe disable it to prevent changes) and see how that goes.

I do the same as well. I flash Radon with balanced profile and don't touch anything in it except the sound settings.
Post something in the kernels thread here at XDA, see what they have to say. It could be something they can fix.

Is it really related to the kernel? Or does it have anything to do with the ROM?

The reason I think it could be the kernel because of earlier changes/reverts they did that slowed down the wake up. It could be entirely the ROM's fault. Does it happen with the stock kernel?

Need to check. I've never used stock kernel of any custom ROM.

Yes. I don't need dt2w at all. I've even turned off Ambient Display.
Cant solve this issue .... Present in 7.1.1 , checked in resurrection remix 5.8.1 ( on many Nightlies) and AOSP Extended 3.1 . Issue present on both stock and Radon kernel.

I use wolf rom v3.8 and auto brightness function don't work. I checked other roms and it was the same. How can I turn it on?
u cant turn it on i think u need to try with power widget ..that has the auto brightness option ..works for me though, should for u too !!
Thank me if it worked !!
I used a lot of different power widgets and they show auto brightness icon, but nothing changes. Android Assistant widget has list of sensors available in phone and under Light Sensor I have: not support? wtf?
with power widget

Lesmian, why don't you try ewjet rom? So far is the best rom out there.. smoother and faster and works flawlessly, including auto brightness feature.
Is auto brightness not working at all or you just cant find the option for it? Mine works fine but no option to enable or disable.
Im on zmod cm7

autobrightness always was VERY subtle on my x10i, it even works "better" on my ZTE Blade, so you may just not see it, the only time i really noticed it was when i was reading on the train and drove through a tunnel.

Hmm. Maybe its true that just not see it. But I did a couple of tests. I lower my brightness and then I put phone under lamp. Nothing changes. Then I increased brightness and cover sensor with my finger, still nothing changes. ;/
Did you read the FAQ section? LOL

If you mean wolf rom FAQ section I read it. And it says that auto brightness works with power control widget. I used it and it doesn't work with my phone. Btw I don't know why you LOL? I did something wrong?
Auto Brightness
I may be able to add some insight into our auto brightness problem. I know it was disabled in 2.1 apparently. First question does anyone know if it was enabled in 2.3.3?
I am currently running a generic X10i with Virgin WB 4.0.4 ROM and DooM Kernel v04b. I use Juice Ultimate Beta v3.6.6. There is a brightness control in JD and I have noticed that on my phone it says brightness sensor unavailable.
The other thought I have is that maybe it is available in x10a's and not x10i's. This may explain the wide variations in people who have it working and people who don't. I have also tried the second step (e.g. larger cirle icon) of the brightness widget in WB's rom which is mentioned in the ROM thread that didn't enable auto brightness. My phone came with 2.1 installed and I have never had auto brightness. This may also be another reason.
I might try and flash 1.6 if I can find it and see what happens. Can anyone think of a reason why I shouldn't try this. I assume I would need to flash a 1.6 basband first.
Any more thoughts would be appreciated.
Hello XDA,
I've come across a really annoying issue for me.
I've downloaded android revolution 40.0 and was advised to run boeffla kernel with it as the stock kernel drained the battery too much.
I installed boeffla kernel and it was working fine, all the tweaks worked!
Now there's only 1 issue that needs to be fixed with this kernel/rom. The home button is very unresponsive when the phone is in sleep/standby mode. Things I've tried:
Using different governors
flashing boeffla kernel obviously
changing CPU speeds
Different options within the boeffla app.
Does anyone have any idea why the button reacts so slow as it does? Is it rom related or kernel related?
Any advice on a possible fix would be very welcome.
Don't be shy :silly:

Define ur term 'slow' how slow is it. 5 seconds?
So after i recieve a call, upon ending it, the back led remains on(sometimes flashing - like when u are recieveing a call)
If i do a reboot, the led turns off. When the phone boots, the led stays off also, only after a call, the led stays on.
I`m using some xposed framework modules like :
DS battery saver
G2 Skin tweaks
SB Icon Hider
stock ROM with dorimanx kernel.
Any ideas what could it be?
Using tricker mod? I think you can change the values with most kernel tuners to remain on and flash for various reasons.
Cheers, J.

what do you mean by tricker mod exactly?
Its a kernel settings modifier. That question kinda confirms an answer. Perhaps something in the aftermarket kernel your running.

I tried searching for anything related to the lock button led in this tweaks windows of the kernel.. but i can;'t find anything related..
I also disabled all xposed modules, but the issue persists. Upon recieving call * doesn't matter if answering or not* the led keeps flashing untill i reboot the phone.
Try going back to stock kernel and see if issue goes away?
Cheers, J.
well this is odd.. even with the stock kernel 3.4.0, the issue is present. hm..
I also flashed the 380 dpi from here but i doubt is has anything related..
Try a clean install and see what happens.
Cheers, J.
I actually installed the G3 ROM from optimus, and the issue was solved. I always wanted to try a G3 rom so i jsut did that.
Strange issue tho.. as changing back to stock kernel and disabling xposed the issue was still present.
Thanks for the help and ideas.
I am miui 8.1.4.0 mm and i am losing almost a 8-10 percent of battery during sleep and screen on time is like 5 to 6 hrs!!!
Previously i got around 8 to 9 hrs of screen on time and also i am using radon kernel in this setup please suggest me a solution!!!!!
I facing this issue for 2weeks ago. Still cant solve this bug even I tried clean flash rom and tried install BetterBattery Monitor to know which app drain my battery while sleep ?
Install BetterBatteryStats. Probably kernel wakelocks? Have you seen something strange?
Do you know which fingerprint sensor is in your phone?

Ok so found the culprit it was d2tw and after disabling it my phone did not lose a single percent of battery during slepp!
I am having the FPC sensor rn3

he flashed radon kernel and had double tap to wake (d2tw) turned on. doing this means battery consumptions because touch screen is always on but display not. when you use stock MIUI and no radon kernel you have no d2tw

Download kernel auduiter from the play store and then grant root permissions go to screen and then disable all the option s there this should fix the issue

Ok got it . Thanks or the info.
Hi everyone, I'm looking for a rom with at least these 3 functions combined: the double tap on the screen off to wake the device, screenshot with 3 fingers, and the traffic indicator . I tried several roms, like RR, Viper, pure Nexus, but none has the 3 functions. If anyone could tell me if that exists ...
Thx very much ?
you can get double tap to wake by tweaking kernel.
Three finger screenshot is already present in these roms.
Traffic indicator is also there.

RR + Radon kernel works best.
Well, I'll try one of those
thx guys
RR and kernel Radon and Kernel Adiutor works fine
