Simply awful software. Just me?

Hi,
Coming from a Moto Z and before that a 6P.
Ok... I didn't intend to hate this phone but... Why are notifications broken? Why dont PocketCasts playback controls work?
I know this is "1 aspect" but to me notifications are vital and i simply don't understand this phone.
- i receive a notification and screen lights up (i set that per app)
- but then I unlock phone
- notifications still in notification shade. I lock device.
- they are no longer on lock screen
Why?
That's not how any other device i have owned worked?
And lock screen music playback is... A disaster?
I consider this phone basically unusable... Yet reviews never mentioned this. Am I alone?

I agree with you, mostly. I'm coming from a Nexus 6P (and many Nexi before that since the One), so I'm used to the plain Vanilla and love it. I was able to rectify some of the notification issues by enabling banner and lockscreen notifications from the Settings >> Notification & Status Bar >> Notification Management area. It doesn't fix everything, and at times (especially the beginning) it was very frustrating. I have it for 5 days now and am at a point where I think it's usable and am waiting for LineageOS to come out with a vanilla-ish version.

The battery is what drew me to the phone and it doesn't disappoint. I can get about 24 hours and that impresses me.

Thanks, have that set for important apps. Feels like a massive part of Android (notifications) are basically missing. Rest is good/ok/great but.... Just feels like madness that this is acceptable in 2017.

yup, hw software sux. end of. waiting for stock-ed customs

Just you

Yea, that's what ended up being the deal breaker for me. I absolutely loved everything else with the phone, but notifications are the baseline of what a phone should be (at least to me), and this phone failed at that miserably. Not being able to reply to a text without unlocking the phone is a no go for 2017. I also kept hearing how battery life was amazing...I never really saw that either considering the size of the battery and a 1080p screen. I've got a Moto Z Play and I can tell you that this is truly amazing battery life. I'm now sitting at 53% with 4:39 sot and been off charger since 9:45a...It's now 1a the following morning. Not putting down Mate 9, as I really did like the rest of the phone...So much so that I'm on here looking to see if they have come out with an update for the glaring problem you guys are discussing. It looks as they Huawei doesn't even acknowledge the issue, so not counting on a fix. Oh well

I'm really surprised Huawei get a free pass on this. I read about 10 reviews, saw lots of YouTube videos and I had no idea how this phone handles notifications. I simply don't believe that someone coming from "normal" Android versions wouldn't find this different enough to warrant a huge rant?
Very frustrating. I like so many aspects of this device but the basic things are terrible. Madness.

for lock screen music playback -
settings> then uptop type in notifications> notifications panal> notification managment. then find the app you want to allow on the lockscreen. hope that helps.

Spot on! I'm 700 USD in on this phone. Only thing going for it on my side is the battery (so far) and dual sim as I travel a lot.
The rest is just unacceptable... At the very best. Likely the first and the last Huawei I'll own.

It's not just software that is bad for notifications. The hardware is poor too. The LED is tiny and almost invisible. The vibration is very weak so you can't feel it in your pocket.
This is a great phone underneath, but the little things really spoil it.
Huawei had a great opportunity to take business off Samsung, but they have blown it.
This has put me off Huawei. I'll be trading in the Mate for a Note 8. Or perhaps I won't wait for that. The S8+ is looking good.

Coming from a Nexus 6, the software has it's issues, but overall I like my Mate 9 so much more. Thought I would be missing the stock Android in a daily basis, but I seem to be very happy with my new phone.

Coming from the disastrous year of Samsungs (s7 Active, s7 Edge, Note 7) Im loving the mate 9. Getting 10 hours of screen on time, notifications havent been an issue at all (Ive had to unlock the phone to reply to a text on every single phone Ive used including iPhone). I prefer the lockscreen stay clean and the led flash when I have something unread. Out of all the phones Ive used this past year, this is the only one Ive kept. Ive got a Moto Z Force sitting on my table thats for sale and once its gone all Ill have left is my iPhone 6s plus and the Mate 9.

Do you find the LED bright enough and the vibration strong enough? If so I have a different phone to yours

I have no issues with the brightness of the led at all, in fact I prefer it to the absurd brightness of the s7 series. My phone is primarily on a desk or table and I havent missied any notifications at all. Also my volume is always on so I hear my phone go off and never really pay attention to the vibration of it but I would say its right on par with my iPhone. Another thing is I use Textra and always have so Ive got the vibration set to "multiple short" and if the phone is for some reason on silent I still hear the vibration when a notification comes in. Honestly I have no complaints about anything with this phone especially now that Ive been able to change out the emojis without root (hate android emojis).

i really like the mate 9, the software could do with abit more though.
if it was pure vanilla, this phone would be the end all.

I use an app called Flash notificationn 2. basically on any missed notifications it keeps flashing the camera and lights up the screen( set every min or so). it works very well. coming from a note 4 i was also tossed. I do love this phone and at 599.00 seems a steal. does it have shortcomings , ya it does. but so does every phone. price to price with the s8+ or note 8 rumored at close to a grand makes this phone a steal. especially considering the list of shortcomings the galaxys 8 will have.

That seems like an odd issue to me. All it takes to unlock the phone is touching a sensor. Unless the complaint is about doing it while sitting flat on a surface, then I agree the sensor placement isn't optimal. But if replying to a text without unlocking the phone is important, that's easily solved with a 3rd party text app, like Textra.
I also haven't noticed the issues with notifications in my usage that others have had. But I do agree the notification LED could be brighter, and the vibration stronger.

This just doesn't work reliably. Spotify works 60% of the time maybe but PocketCasts about 5%. Totally rubbish.

Really mixed bag of opinions here.
I'm almost wondering if there are multiple software versions showing different behaviour?
The 2 notifications issues i have are :
1. Music playback controls. Dreadful. Seems like some apps whitelisted but even those don't work 100% of the time. PocketCasts (even latest version from 2 days ago) works basically never, meaning i need to unlock phone to pause. A total joke.
2. Notifications. Lock screen shows them once and once only. As soon as i unlock, all notifications are not shown again on lock screen, unlike normal Android.
For those that "don't have issue with the notifications"... Do you see what i see?

I know on the launch they talked about the light on the edge of the screen.

You're not missing something, it's supposed to come in a future update soon. I think it was mentioned in that ask me anything on oneplus.com

Think it flashes for one second. Dont have the phone but I think you can enable it in display settings somewhere

There is no option that I found to turn it on or off. It just works....When you receive at text you will receive a blue light is going to appear down the curved side of the glass. It happens really fast. They should really have an option to extend how long you will see it for.

You probably just need to have ambient display enabled for new notifications. Bit of a useless feature mind you.Needs inprovment to flash or pulse but could then become a battery drain

According to an ask me anything session in their forums they are looking into making it more customizable and are also considering adding Always On Display:
Q: Any enhancements in OOS to utilize the curved display in 7Pro?
A: Edge lighting for notification would be a handy feature and we are still considering to add more features that will utilize the curved display in future.
Q: Are the edge notification colors customizable?
A: Not as of now but its something we are considering for future updates
Q: Is there any consideration of added a Always On Display feature? I currently own the Galaxy S8 and I actually like the AoD feature.
A: It's still under consideration. We are working on improving power consumption efficiency for this feature before we implement it.

The edge lighting is pretty useless as is. It flashes for one cycle then disappears. I don't understand how OnePlus thinks this is of any use. Normal people don't stare at their phones all day hoping to catch a glimpse of a notification. I also don't want to have to pick up the phone or tap the screen to check. They opted for no LED, so make edge lighting persistent and customizable. The promise of this feature was actually one of the main reasons I upgraded from the 6T. The 7 Pro is a very impressive device but edge lighting in its current form is worthless.

I was just getting ready to post this. I used it on my 6T, S10+ (untill Holey Light came out) and now also using it on my 7 Pro.
Once set up it works great.

Still don't have the phone, but does this app cause the phone not to go to deep sleep (causing loads of wakelocks)? And does it contribute to screen on time? (meaning that the phone thinks that you're using the screen while it's only the edge lighting that is on).

Makes sense to stay until cleared (comparing with Samsung devices all the time clock on). At the end this is the same display which can handle it without too much battery drainage

Moto Active Display? (or similar?)

All the incredible steps forward in phones and ROM's, and I still can't get myself to forget how much I looooved that Moto Active Display. I miss it so much. ?
Seems like such a step backward not to have it, and Android always seems to be about having everything you can imagine.
Is there any ROM's, Modules, or Apps I can use on my 7P to get this feature back?

What features you talking about specifically

The display screen flashes when you get a message, and will continue to flash occasionally until you pick up phone.
Anytime you wave your hand over screen it wakes up for a moment.
You can push on any notification and it will give you a lot more info about that notification.
If you swipe up on a notification it will take you directly to that app.
Much more interactive.
I'll find a YouTube video...

You can skip the 1st minute...

I think back in the Android 4.3-4.4.4 days we had this features even in custom Roms. I wonder why its gone. Todays active display is nice but is much less interactive. I would also be happy if some big dev would make some code which the ROMs can implement it.

Probably because drained the battery too much. Today's AOD consume only 0.1-0.5% per hour.

This app has all that. Having it just to light up when you touch the screen shouldnt take much battery. Keeping it always on however is another story.

Yes! ☺
Yeah, it came on my 4.4.4 device.
It was when Google owned Moto, so it gave Moto better access to Android to do something special, and everyone always seemed to agree Moto did it better than Google, but it has disappeared. ?
The app discussed after your post seems it might offer some of that though. I'm gonna check it out.

I have heard this discussed, and, while I understood the concern in theory, I never understood d it in practice.
Meaning I used a phone with it for a long time (Droid Turbo) and I always felt like I had GREAT battery life. Granted it was a big battery @ the time with 3700,but I got 2 days out of the battery sometimes, and I'm not a light user.

Batteries complains are nonsense. It consumes less then a regular always on display. Its just a features which dissapeared for some reason (as others did also).

I DL'd it and have been playing.
I found the preview to see what it will look like, but waiting for a notification to come in to make sure it actually turns on is like waiting for a kettle to boil...only worse, cuz ya can't tell if the burner is on.
Looks like it's gonna do the trick though. ?

AOD, notification light? Alternatives.

Ordered my OP7P today buy I'm quite ready to cancel it. I knew that there's no led notification light but was 100% convinced that there will be some sort of alternative. From what I can read there's nothing like that? No AOD, no nothing. I mean - really? Any third party apps?
Please don't tell me that I have to DT2W every time or worse - lift my phone to check battery percentage (if on charge) or notification icons? I found similar thread on OPs community forum that was closed after 4 replies and with suggestion of.... getting a Samsung phone. Bloody joke.
So, any alternatives?

Well you have to tap it once to wake up te clock, and immediately after you picked the Phone the clock is also waking up. For me it's fine. For you maybe annoying. Some guy here made a notofication light on the screen but for now at least it's battery draining

Lift to wake is very sensitive where even slight movements will trigger ambient display.
I'm on a custom ROM though and this has AOD baked in but even if I was still on OOS, lift to wake is perfect for me.

I remember Ambient Display from Nexus phone and it was terrible. But at least I had notification light back then.

Someone did make an app for the 6t and I think it works for the 7 pro also. I think it's called notifybuddy.

NotifyBuddy is great, but don't use it if you use OK GOOGLE as they clash. Use pixel pulse instead

NotifyBuddy indeed is great, but it totally drains your battery. I am now using "Plus Beat" (find in Play Store) which uses your complete sides of the screen. Per app customizable, works great together with Renovate Ice

Just download an AOD app l on the play store or install a custom rom.
But canceling your order simply because of that is a little weird... Especially when there's loads of options available. Also, did you not look up all the details about the phone before ordering? If so, maybe next time look at ALL the info for the device you're about to buy.
Assuming something with no research, especially with new technology, will always bite you in the ass

Display Issue on two Note 20 Ultra

I bought myself a Note 20 Ultra Snapdragon Version (Hong Kong Version). After around 2 weeks right we’re the proximity sensor is, a dark discoloration started to appear. It’s not super good visible, but still it was there. I tried to overlook it but couldn’t. So i started a repair/exchange process. After a huge war to get a perfect device the shop where i bought the mobile exchanged it with a new one. But again after 1 week this weird dark spot started to appear. Sometimes the splotch is faintly visible, sometimes he is very visible. Now i have payed 1300 Dollars but can’t have a perfect display. Anyone having the same issue?

Ask yourself , what rogue apps are you heavily using that cause this issue. These things normally occur during using VoIP apps on high brightness with screen left ON for long durations. Heat , bright screen and VoIP apps that use the proximity sensor continuously degrade it.

First i use the mobile on very low brightness since i got it. Secondly i used nothing like the apps you described. So i can’t see how i caused this. And I’m not the only one. There are other cases with exactly the same issue. It’s a design flaw.

I forgot to mention that i carefully checked the battery temperature and cpu temperature all the time to avoid unnecessary strain on the display and the internals. But still after a short time on both mobiles the same issue.

Lol i own the mobile max 2 weeks. In this two weeks i watched videos. I used whatsapp for texting (maybe 2-3 phone calls). I used a video player to watch download videos, but i used nothing that would have left the display on for a long time with the proximity sensor working. I used the phone more for media, because i still own my iPhone 11 pro max for phone calls and alike. Hence i can’t explain why this is happening. I’m the first one who would say yeah i used the apps you mentioned on high brightness all the time, but that’s not the case.

Btw your sarcastic questions are unnecessary. If you think your clever and everyone else is a moron, nice for you. But the Note 20 Ultra is not my first mobile, and i know what to avoid, and what to do in most cases. But when i get the same issue two times in less than 2 weeks without doing anything maybe causing this, i think it’s ok to ask if anyone else is having the same issue.

No worries bubba. I hope you find an amicable solution soon.

Yeah every n20u has it. Some people just don't have the eyes to see it or choose not to / conditioned to ignore it.
I can see it on demand but I forgot it was even there till this thread. No way around it, it's a design flaw of this generation.
My n10+ isn't visible unless it's being used but what can we do, Nothing.

My US Note 20 Ultra has that as well. I didn't notice it for 3 months, then there it was. It is from the proximity sensor, and it's only visible in dark environments, and on days when I've had long calls. Other times, it's not visible at all and I'm guessing the sensor is under the screen and that the visible flashing causes it to slightly offset the AMOLED pixels. Every Note 20 Ultra I've seen also has image retention issue (not to the point of burn in) but high contrast images fade off the screen for about 5-10 seconds and this is only visible on gray backgrounds. Looking for a "perfect" one may be a waste of time.
