Wake up delay - Xiaomi Mi A2 Lite Questions & Answers

Hey guys,
got my Mi A2 Lite just a few days ago, I really like it for now. But one thing bothers me a little bit: After waking it up - doesn't matter whether through fingerprint or power button - it takes like one second until the screen turns on. Is that normal?
I'm only used to my Redmi 4X (lastly running LOS 16) and it felt like it was much faster there, even though it is quite a bit older.
My device is quite vanilla (only magisk with adaway and some normal apps), but I think it felt the same right after setting it up clean.
Would be nice if you could share your experiences.

Thats weird... Mine doesnt do that its almost instant when i wake the phone through fingerprint or power button doesnt matter... You should probably get that checked

I really think that is true,mine do the same thing when be in sleep for a time
I compared the speed of screen on with power button with my very old Xperia Z and the sony was faster by all means

Same thing here, after updating to android 9 pie the screen comes on after maybe 3-4 seconds! But this happens only sometimes.... Today. I even missed a wake up alarm. It seems like the phone goes into a "too deep sleep" mode and can't be waken up. Will go back to Android 8.1...

be careful about downgrade - people have problems with sim cards after downgrade back to oreo.

I have the same problem

Yea, i have the same problem, really annoying. Maybe it has something to do with simcard or something idk.

I had the same problem too. I use my phone with 2 simcards and 1 sd card. After I remove the sd and disable sim 2 , the wake up delay disappeared.

Fingerprint scanner randomly not working

I'm just trying to narrow down why randomly the fingerprint scanner does not wake the phone. It might happen once a day or not for a couple of days, but it seems to always come back. Not a huge deal since the power button will always work, but it is disconcerting when it happens. I'm not using any power widget or lock program although I do use Nova Launcher Pro. Does this happen to anyone else and if so have you narrowed it down?
Mine always wakes my phone, although every now and then it doesn't recognize my print. However, I believe it's because of how my finger lays on the sensor so I think it's user error in my case.
I've registered 4 prints, 2 from each index finger and all in different positions on the sensor to get the least reading errors.
Are you saying that you get no vibration as in it doesn't even register at times therefore you HAVE to use the power button to wake it?
I use nova pro too.

Yes exactly, no vibration. I've had it where it vibrates and doesn't unlock because my fingers are slightly wet or something. This is like it doesn't even know my finger is on the sensor. Power button unlocks and then it works again. Last time I said ok I'm not unlocking with the power button I'm gonna get this to work. Nope, had to power button it on after a minute or so of trying. As I said, it's not that big a deal and only happens once in a while. Glad it's not Nova though. Kernel dev said it's not the kernel , I'm using Elemental X. I might try going back to the stock kernel just to test it out. Problem is that I can't reproduce it.

I get this occasionally when charging but that occurred on stock everything, can't say I've noticed it in any other capacity. Are you using smart lock or an app to lock your screen?
Edit: I should read your post before replying, disregard my app question. Still asking about smart lock though.

And I meant to include the "big" question in my original reply. Big being "what mods are you using"
Best way to trial and error issues as you well know? I'd test it on all stock (for a day or 2) and see what that gets you then you can narrow down to if it's the kernel or not. I'm not a kernel dev, but an educated guess would point to that imo

Smart lock, yes. Well smart unlock isn't it? I have a couple of BT unlock devices, Mi Band and car BT radio but that's it.

No mods.. well let me rephrase that. I have a bunch of programs running naturally, but the only "mod" I have is Cataclysm and systemless root along with Elemental X kernel. Cataclysm is considered a mod these days as it's just an overlay on stock 6.01. I know I'd have to go full stock to test for a few days but I'm so so trying to avoid that as I'm sure you know. Thanks for all the input guys, I know this can't just be me right? Hey wait a sec.. I do have a BT smart band unlock running. I'm going to take that off and see if that makes a difference. Maybe that is interfering with the fingerprint requirement.
Edit..nope not it. Gonna run stock kernel next.
The exact same thing is happening to me. Same symptoms but I am on fully stock. I'm also using nova pro. Been searching around for an answer but haven't found anything.

Too many people on Nova Pro for it to be an undocumented issue. I know it's been said that it is not the kernel, however, yesterday morning I flashed this one http://forum.xda-developers.com/nexus-5x/orig-development/jolla-kernelbullhead-t3271530 and I've not had the issue since. I usually have it at least once / day and none so far. That doesn't mean it's not going to happen in 5 minutes though. I went with stock kernel values if you're rooted and feel like giving it a try.
I was having this issue randomly when running custom hotplugging. Currently no issues with default cpu hotplug settings and ElementalX.
For me I have a case on my 5x. There are two cutouts - one for fingerprint sensor and one for camera. They're both about the same size. Every once in awhile I find myself reaching for the camera instead of the fingerprint sensor. When I first got the phone I thought my fingerprint wasn't working at times. Turns out I was just putting my finger on the camera instead of the fingerprint sensor. Any chance this is what's going on?

Don't make me question my own sanity! hehe. I did the same thing at the outset but quickly realized my error. This is not what happens here, however. I even put it back in my pocket once to make sure it wasn't some aberration. It just wouldn't recognize there was even a finger there. Almost thought the phone had shut down but power button got it working again. Haven't had the issue in well over a day now with this kernel but I'm not sure that's what it is.

This has happened to me twice. Both times while charging. Has not happened any other time. (stock everything/not rooted)

Happened to me not charging, rooted with custom kernel. So it's across the board hit or miss. I have a feeling it will be fixed in an update or OTA. Not a deal breaker just odd is all. Oh well, if we didn't have a power button it would be major.
After 3 years of usage my Nexus 5X fingerprint scanner stopped working at all and i can't do anything about it apparently. The issues started when i sent the phone to LG to fix the bootloop

LeEco Le Pro 3-- red screen occur when pressing the power button to turn off.

Hello everyone, I got LeEco Le Pro 3 two weeks ago. For the past two weeks of testing, I notice that the screen quickly turns red when pressing the power button to turn the screen off. Is any of you facing this problem? It happens randomly, not every time. I have attached the video in slow motion capture in the 7z zip file. So you can see, what I am talking about. Let me know if any of you see it.
In mine sometimes it blink red. Power sleeping your phone rapidly. May red screen is reaction for force kill app?

I did not power sleep my phone rapidly. The red screen still persist. I don't know if force kill app cause it. I submit the feedback through the leeco experience center about this issue. This is what I got from them:
"Le Engineer
Hello,
I just get some information for this issue, in low battery level the red screen issue will happen sometimes. We also find the same thing on other brand device.
However R&D team are working on it. Hope it will be fixed in next generation product.
Sorry for inconvenience. Thank you for choosing the LeEco."
So I don't know if my phone is defective or not. It's hard to tell. Base on this message, look like there is no fix for this.
I saw this movie. My phone behave as same as your <sometimes>. May it's EUI problem? Somebody on other ROM like MIUI or CM13 can say something?

Mine occur sometime, too. Here is what I analyze:
1. On the home screen; when pressing power button to turn off, red screen occur sometime.
2. Any app that has white background like the waze app I use in the video, red screen occur every time I turn off the screen while leaving the app running. That goes for other app like chrome, whatsapp, google map, gmail, etc. Same result.
3. On the back button, when I press hold, the screen turns off. No red issue. This was on the home screen and this rarely happen. But for apps that is open, same issue.
That is what I like to know if it is hardware defect or software EUI problem. It looks like software issues. It would be great if someone would test it with different roms such as CM13 or MIUI.

It could be a software issue since I don't have that on CM.

I never seen with MIUI 8, can anyone give me a sequence to try ?
Tried some times, shut down it's too rapid to see with MIUI.

If you have another phone with slow motion support just like I did, you can try that.
Other thing I want to mention, I would like to know that if the red screen does not happen to people who have CM or MIUI on lepro 3, can any of you go back to EUI and try to do the same steps? If you can. This would more confirm that the software is the issue and not the hardware defect.
Any update?
Hi folks! I've been searching for this rare issue since I got my LM2 last week. I have the very same issue and I notice the same @crazy1990 mentioned here. Besides, I notice this red light is more noticeable when the brightness is higher.
IMO, I don't feel it's a matter of bad hardware (I hope so), as there are no clues of any other issues at all. I'm also using stock (23s) and I suspect it's some poorly designed fade for the ROM.
Any updates from anyone?
Yes. Red screen blink is noticeable when the brightness is high. As of June, I still have this issue since November on this stock rom 21s. So far, there was no screen degradation or any kind of lcd problem. Lcd works perfect since day one. A while back, I installed lineageOS and I still experience red screen when the rom froze and reboot. At this point, I still don't know if it is the software or hardware. I hope someone can help us out.

No, but I already tried omnirom and purity rom. No red screen issue. I also tried tars 21s and turbo base rom, the issue is there.

Great to know it doesn't happen on Omni/Purity. My biggest concern was an increasing degradation and/or flickering issues arising when changing to a stock ROM.
Thanks for your information.

Display wakeup issues after screen replacement

Hey guys,
About 1 month ago the screen of my OP3 broke and I bought a replacement on eBay.
After the replacement I encountered problems, which only occured from time to time. Sometimes when waking up my device the screen stayed black.(Like on every 20th attempt it happened once). After pressing the power button some more times, the device finally unlocked. I am 100% sure that the device always unlocked on uneven attempts which means that the device at least woke up software-side.
I was totally sure that my replacement screen was kinda flawed and it is a not fixable hardware problem.
Then one week ago I switched from official LOS15.1 to the unofficial LOS16 rom and encountered big differences. The problem got noticebly worse. Waking up the device was a pain in the a**, it never worked on the first attempt on this rom. It's not unusual that it takes between 11 and up to 60 tries to wake up the device which makes it nearly impossible to use the phone. As before, the screen at least turns on software-side after every attempt. I can see this because the hardware buttons always light up.
Now after one week I switched back to official LOS15.1 and voilà, out of 20 attempts, the device instantly unlocked 19 times.
I know it is hard to understand and even to analyze such kind of problems, but there must be some solid solution for my problem.
Atm my clue is that original screens always offer more functions (e.g. gestures) than replacement lcd screens. Those functions are always connected to the software(rom). Is it possible that there is any other function (e.g. anything related to tap2wake or deepsleep) which is able to prevent my screen from turning on?
To deliver some more infos:
- I used standard system settings on both roms to test this out.
- "prevent" accitential wake up is turned off
- tried to disable gestures
- I tested my proximity sensor via an app, it seems to work flawless
- waking up screen in twrp is also very difficult and needs around 15-20 tries. Does anyone see any pattern?

You most likely got a bad part. OEM like One plus and xioami are known for using something called product binning. Which means their parts have a higher failure rate then other oems. They also dont make extra parts really so what you got was most likely just a generic screen like you can buy at any shop in China.
Nothing you can really do about it except try a different screen but to be honest I would get a different device and this time dont skip on the price. You get what you pay for and when a good device is cheap there is always a reason. (why do you think most of the owners and mods of XDA run Iphones as their daily drivers and leave android for a hobby)

Hey there again. I know my answer is kinda late but I wanted to share my experience. So I tried like 10 different custom ROMs with different Android version. The problem got even worse sometimes.
Anyway a few days ago I installed stock OOS and the problem is fixed now. I could not believe at first, but after excessive testing I am 100% sure now.
Anyone can tell why? Is the stock display driver proprietary?
TBH I always used to use custom ROMs (mostly CyanogenMod and now Lineage. Now on stock rom O feel like everything is better than ever before. Battery life, performance. Some features even offer more customization than custom ROMs.
I always thought the opposite is the case since custom roms advertise things like this. I will definitely stick with stock rom for now!

Thanks for the confirmation. The cheaper screens seem to have an issue which is not faced by the costlier ones. I have found while roaming the threads that sometimes flashing OOS helps. May be a driver issue.
My understanding from what I've read, third party displays needed kernel support.
I paid OP to replace mine - no problems.
Hi!
I'm having a similar issue with my Oneplus 5. Had my screen replaced (new one: OEM) and now it doesn't wake up most of the time either using power button or double tap or fingerprint scanner. I tried everything that I read on forums but nothing worked. Now I seem to have found a solution that I haven't read anywhere yet: I turned off night mode and now it's working as it should. Actually, whenever I want to use any screen adjustment feature like night mode, reading mode etc the screen doesn't wake up. But if I keep the default settings, there is no problem. The issue is definitely the new screen because before that I used night mode all the time (I mean after dark). Now I'm still thinking if I should return the phone to the repair shop and ask for another screen (they offer one year warranty after the repair) or just deal with it... I mean these OEM screen are cheap for a reason (as someone had written here before) and there is no guarantee that the next one will be good, and I don't feel like waiting weeks again for an uncertain outcome, also I can live without said features (gonna miss night mode tho'). Any suggestion? Should I give it a try? Maybe the repair shop made a mistake during assembly? Anyway, I hope this comment will be helpful for those lurking for a solution for a similar problem.

Did you try OOS?
OEM screen is not cheap (atleast compared to what is offerred online).
May be you are better off with what you have since you have found a work around. Who knows what you will get next time?
Yea I have same problem it works totally fine on oos but on custom roms it is ****ed up

Thank you also for confirming that on OOS there is no issue. Looks like the cheaper of the online replacements have this issue while the costlier ones don't.
Funniest thing is I have a slim ROM backup on 7.1. and that works fine so like what the f--- any ideas people?

Hey guys,
About 1 month ago the screen of my OP3 broke and I bought a replacement on eBay.
After the replacement I encountered problems, which only occured from time to time. Sometimes when waking up my device the screen stayed black.(Like on every 20th attempt it happened once). After pressing the power button some more times, the device finally unlocked. I am 100% sure that the device always unlocked on uneven attempts which means that the device at least woke up software-side.
I was totally sure that my replacement screen was kinda flawed and it is a not fixable hardware problem.
Then one week ago I switched from official LOS15.1 to the unofficial LOS16 rom and encountered big differences. The problem got noticebly worse. Waking up the device was a pain in the a**, it never worked on the first attempt on this rom. It's not unusual that it takes between 11 and up to 60 tries to wake up the device which makes it nearly impossible to use the phone. As before, the screen at least turns on software-side after every attempt. I can see this because the hardware buttons always light up.
Now after one week I switched back to official LOS15.1 and voilà, out of 20 attempts, the device instantly unlocked 19 times.
I know it is hard to understand and even to analyze such kind of problems, but there must be some solid solution for my problem.
Atm my clue is that original screens always offer more functions (e.g. gestures) than replacement lcd screens. Those functions are always connected to the software(rom). Is it possible that there is any other function (e.g. anything related to tap2wake or deepsleep) which is able to prevent my screen from turning on?
To deliver some more infos:
- I used standard system settings on both roms to test this out.
- "prevent" accitential wake up is turned off
- tried to disable gestures
- I tested my proximity sensor via an app, it seems to work flawless
- waking up screen in twrp is also very difficult and needs around 15-20 tries. Does anyone see any pattern?

Yes, I have the same issue and I wanted to revert back to Stock OOS, but I just tried Caesium latest kernel, and the display wakeup issue seems to have gone. I'm using Havoc OS 2.3 based on Android Pie.
Guys the latest mad kernal reborn it wakes up all the time
At least for my screen
It used to be worse on all the other kernals
Finally found a solution
I had same problem on custom roms after replacement of display of my oneplus3...i was on oos 5.0.8 i had no issues in that but am a custom rom user and now the solution is flash any rom clean flash not dirty flash and flash gapps then flash any module if you want like magisk and then reboot setup the device and after first boot flash mcd custom kernel and yippeee enjoy... Present am on havoc os with no issues... Try and let me know...

Lots of different small issues

Hi all
I have been using this phone for a month, and I have experienced a lot of different small issues, I hope someone may have solution to them.
Phone:
Mi A2 Lite, rooted (Magisk) Android one pie, January update. Has a screen protector.
Apps:
Here are some apps that I think may cause the issue that I mention below, these apps are Nova and datally. Really can't think of a third one, I don't use any cleaning app or battery performance app.
Issue:
1. Typing experience is horrible. Using stock google input, the keyboard is not very sensitive and accurate. The letter just can't be recognized even though I am sure I have pressed the key and pressed the right key. So my typing is really slow, the key doesn't display immediately (it does seem to have a delay), and for some reason I always type wrong and missing some letters, so gotta use backspace a lot.
2. It always wakes up randomly in my pocket, so I may take the phone out with torch on and airplane mode on without my awareness.
3. When I am on a call, I can accidentally press some random on screen keys.
4. The background apps AWALYS get killed, even though I have turned the battery optimization off globally, and the individual apps that I never want to be killed.
5. Messaging service apps have huge delay when delivering the notification. It may only show when I open the app. Used PNF app but couldn't fix the problem.
Does anyone have the same issue and know the fix?
I hope it is only the software problem (Pie system) and maybe I can fix it by flashing a better rom, but I don't seem to find a stable official custom ROM for Mi A2 Lite (even lineage OS is unofficial)
Many thanks

Do you have all these problems? or just one or two? After seeing my configuration/apps that I installed, do you think is it app related or system related?

all these problems without wakes up in pocket. killing the background application is the biggest problem for me (I use a lot of smart home app- eWelink,Room Heat,Magic Home) and it's horrible. ewelink starts 5sec after kill, Room Heat - frequent crash like a white screen...
the next problem is huge delay when delivering the notification....
I am on Stock Android One-February update,I'm allowed only cam2api...

You have battery optimization off? any battery improvement app? I think all these is because the 'intelligence' in Android is playing up, it doesn't understand exactly how we use the app. However, even have it turned off, the problem exists....

Don't understand why there is such different, did you have battery optimisation off and all time since the first day you use the device?

Yes, all off - battery adaptation and manually set no optimization on my app...

Question Inconsistent double tap to wake

Dt2w works fine for the first few minutes after locking phone but after that, it requires 7-8 taps to wake up. Anyone else experiencing this? Im using xiaomi.eu 12.5 stable.

I'm on the weekly and I also have this issue. Not 7-8, but I have to tap twice. Like 2 taps then 2 taps again. Happens sometimes.
all good on ArrowOS, DT2W and sleep working great... i know it's possibly not what ur looking for... but it's a seriously good rom.

Yes, this happens also for me
I'd assume this would also be an issue on the Global rom?
If so, we can bring it to Poco's attention via Poco community forum.
Otherwise, we'd have to bring it to Xiaomi's attention on the Mi community forum.
I noticed this too but for me it’s the very slight movement between taps where it presumes a gesture is upcoming. It also seems a little worse with a slippery tempered glass protector.
If I make a conscious effort not to move position between taps it works for me every time. Maybe they can adjust swipe detection sensitivity?

this any good? or there's others if you search playstore....
this one maybe
(as a possible temporary solution, i mean)
EDIT: sorry, i read ur post as a touch sensitivity issue. have re-read, don't think those apps are of much use
Interestingly, don't have problems with double tap to wake, it works always, only with tapping for always on display to quick check time or notifications. Works 1 in 10 times. It's funny, tap, nothing, double tap ok.

same issue
Same issue, probably the biggest annoyance for me since I'm almost unable to use 10 second AOD tapping to conserve standby power.
Any power management active?... destroyer of worlds.
Try clearing system cache, and a hard reboot.
Try altering AOD settings or clearing apk data.
Maybe a firmware glitch... they happen.

Already done this to fix my drain problem one day one of receiving the device.
I know Android is just like any other OS installed on a computer sometimes needs clearing of cache, a shutdown of the OS or a manual reboot.
In fact I've done it many times just to make sure MIUI is not glitching on me.

You be amazed how many have no clue or just don't think using of it.
It may be a settings glitch or again some sort of power management running amuck in the background. Play with it...
I posted the issue on Mi Community and Poco Community forum.
Not many people seem to use the double tab to wake feature with AOD set to 10 seconds.
I tried searching on Xiaomi and Poco both forums with keyword double tap and not a single thread for the Poco F3/Redmi K40.

I think youre right bro. If i time my taps perfectly and dont move position between taps, it works most of the time. Same goes for the AOD. Single tap works but it takes almost 2 seconds for the AOD to pop up which is pretty slow imo.
I think figured it out, 3 fast taps without moving my finger always works with AOD now.
Whatever, I'll just leave the posts on the Mi and Poco forum...hopefully they can replicate the issue and improve single/double/triple tap detection with future updates.

Bro did you try single tapping and waiting for ~2 seconds?
Everything magically works now, after I let the battery deplete to 0% (MIUI auto shutdown) for a second time and then charge to 100% (for initial battery calibration).
Of course I won't be letting the battery deplete past 20% anymore after this, and I'll only be charging up to 90% when I have the phone rooted.
I'm pretty sure there some other minor issues with MIUI I haven't encountered yet, but for now it's pretty enjoyable to use.

One question, double tap to wake drains battery on Amoled screens? read somewhere that it was a function for LCD displays

Might depend on the device. Doesn't use much at all on my Samsung Note 10+.
With AOD touch to view active and phone/text running I use less than .5% @HR.
Never tried deactivating Double Tap on though... it's too useful.
More than likely it's not the culprit. Cloud apps and trashware like WhatsApp, FB, Google system apks are prime suspects.
Easy enough to test...
