[Huawei Watch] BadContext:
I would say the wireless charging is the only thing the 360v2 really has over the W1.

From my original research, Moto360 Gen2 vs. Huawei W1:

360X330 "flat tire" LCD (BACKLIT LCD!!!) display (yuck) vs. 400 X 400 OLED

Corning Gorilla Glass 3 (can scratch) vs. Sapphire Crystal (really, really hard to scratch)

No internal speaker (deal breaker for me) vs. a very nice internal speaker.

Doesn't look nearly as good (in my opinion) vs. arguably the best looking Android Wear watch.

The combination of these items meant that the Moto 360 wasn't even in the running when it came time for me to make my decision. The line of smartwatches from LG were the only competition. If Samsung had gone with Android Wear instead of Tizen then they would have also been in the running.
[Huawei Watch] Furqan Ullah:
Very useful information. Thanks. But what about the miss of ambient light sensor? Do you feel that W1 is still pretty good without it? You think it's not an issue to control the screen illumination throughout the day by manually?
[Huawei Watch] BadContext:
Well, Motorola mainly included the ambient light sensor to make up for the fact that they went with an old-school backlit LCD. In order to keep the contrast ratio (and thus black levels) decent, the light sensor is used to dynamically reduce the backlight in an attempt to keep nice black levels in all lighting conditions. If it didn't, all black backgrounds would look dark grey in low-light situations. Most modern LCD TV's have an ambient light sensor for this purpose. This dynamic dimming of the backlight does also has the effect of reducing battery drain, which is nice.

If memory serves, the "flat tire" in the display is there because they had to find a place to install the ambient light sensor. I believe that's the reason most if not all other current-gen watches went without one as there's nowhere to put it without affecting the appearance of the watch.

Would an ambient light sensor help conserve battery life? Yes it would, a little bit. Would I be willing to give up part of my display for one? Nope. I have found that the watch lasts me all day and since I charge it every night, it's not that much of an issue.
[Huawei Watch] Furqan Ullah:
Thanks alot [emoji4]
[Huawei Watch] BadContext:
You're welcome!
[Huawei Watch] C3C076:
I agree with everything already mentioned by [MENTION=7415528]BadContext[/MENTION]

Regarding brightness, I have brightness of my watch set at level 3 out of 6 all the time and I never change it manually.

When I need more brightness e.g. in direct sunlight I simply press button trice which maxes out brightness for couple of seconds.
[Huawei Watch] 1112ee:
Does anyone have this problem on dev preview 3?

What about a custom rom/kernel?
[Huawei Watch] Furqan Ullah:
Working fine on Custom Rom. I m using CM 13 and having no issue on it.
[Huawei Watch] OnnoJ:
[MENTION=6954052]Furqan Ullah[/MENTION]: Just comment on flat tire and ambient light sensor: (at least) Gear S2 has well functioning light sensor without flat tire or other compromise.
[Huawei Watch] Furqan Ullah:
No flat tire and no ambient light sensor. I don't feel any need of ambient light sensor as the custom level 3 is the best level in every conditions.
[Huawei Watch] albenex:
own a Huawei watch 1 since a week and just in darker spots I notice red tint instead of pure black. in the past I had a LG urbane which definitely had better contrast but I had to return it as retention and burn in appeared. so I prefer Huawei one :D on "normal" daily use you won't notice that tint and as someone else said Huawei is aware of this as not claiming to have infinite contrast.
[Huawei Watch] d0e01:
I got mine on 10-24 . I have the same problem
[Huawei Watch] suzook:
Sorry, screen before that one. Build #?
[Huawei Watch] tsells:
Build # LCA49B
[Huawei Watch] suzook:
Strange. So far your the ONLY one with a perfectly black screen.
[Huawei Watch] tsells:
I don't know what to say, but there must be others. It really is BLACK with no red glow/tint at all.
[Huawei Watch] dunjamon:
People have said that when they use a full black screen in a dark room they can see the red tint. Yours looks to be OK.
[Huawei Watch] suzook:
I do see a red push in the pic with the watch face on though.
[Huawei Watch] wy1d:
Try a pitch black room (like a closet) with an SLR long exposure. I see it with my naked eye but it's impossible to capture on a cell phone camera.
[Huawei Watch] wy1d:
That is a lit room. Most cameras don't have dynamic range enough to pick it up in a lit room (especially cell phone cameras). Looks like too much light for even eye to see. Try a closet or pantry.
[Huawei Watch] suzook:
I guarantee it has the red tint.
[Huawei Watch] swngdncr:
My suggestion would be to put a negative review on Amazon pointing out the problem. The sales volume from there is got to be pretty significant, if they see the product rating start to go down because of negative reviews, they may be more responsive. I did have a Huawei representative respond to my negative review on Amazon, so we know they are watching it.
[Huawei Watch] Skin1980:
I made some tests today with suzook watch. Now think that isn't kernel related. I say this because I tried to start the boot animation with the screen in ambient mode, the red tint were not there.
[Huawei Watch] Skin1980:
Can you post using ADB the output of this command:

dmesg | grep panel
[Huawei Watch] wy1d:
Really? I definitely see a red tint during the boot animation (if I boot in a dark room with my eyes adjusted to dark light). I bought a 2nd watch on Amazon and when I turned it on for the first time in my pantry, I saw the red tint. So far I haven't seen anyone post an image with a SLR long exposure in a dark room that did NOT have the tint.

But I have two watches WITH the tint so I doubt I'll be any help with looking at kernel, panel, etc.
[Huawei Watch] tsells:
I have no idea how to do that. Sorry.
[Huawei Watch] brizey:
No output. Any other terms to look for?

BTW, here is how to use ADB over bluetooth.

And to shell into the watch instead of phone:

adb -s localhost:4444 shell

It's working, in that I can find other stuff like lines with the word "errror".

I grepped "video" and got some warnings for drivers.
[Huawei Watch] Skin1980:
Can you try directly after the boot?
[Huawei Watch] Skin1980:
Pls look at the post above. We need it and do that directly after the boot. Thanks
[Huawei Watch] brizey:
Going to bed now (hey! I'm old, lol). Will check tomorrow.
[Huawei Watch] Skin1980:
Ok thanks.

If you can try to reboot bootloader and che k if the red tint is there. Suzook told me that isnt present but some proof more would be appreciated.
[Huawei Watch] wy1d:

[Huawei Watch] brizey:
+1 on no red tint on bootloader screen. It's a little hard to tell with all of the white text, but I let my eyes adjust a few minutes and I could not see the red tint.

So the good news is that it is likely not a hardware issue (unless suzook and my eyeballs are messed up, lol).
[Huawei Watch] Skin1980:
Thanks. What about fastboot?

Adb reboot bootloader

The red tint is there too?
[Huawei Watch] brizey:
$35 on alibaba!
[Huawei Watch] wy1d:
Yes - here is the album (I sent in PMs):

http://imgur.com/a/kucSt

It's harder to tell with the bright white text that isn't being dimmed by the system but it is still there. Pics are compared to my Note 4 in DL mode.
[Huawei Watch] wy1d:
What is? The display? Link?
[Huawei Watch] brizey:
Just google the brand and model from the dmesg posted above.
[Huawei Watch] wy1d:
Yep. Found it. Hmmm...
[Huawei Watch] brizey:
Anyone know how to reboot to bootloader without using adb?
[Huawei Watch] Skin1980:
Give me 30 mina and i will try a kernel with less bright fastboot display
[Huawei Watch] notsointeresting:
Just got my watch. Same exact issue. I really hope this is software related. This is eerily starting to remind me of the HTC One M7 purple tint issue where it took HTC over a year to acknowledge it was even a problem.

http://imgur.com/7gsvOPk

Taken using a note 5 with a 10 second exposure. Kind of shaky but it shows the red.
[Huawei Watch] Skin1980:
Found a way to control rgb channel. It works at least on my urbane and probably also on the huawei. I'll keep you updated
[Huawei Watch] ajamudc:
I am not having this issue. My screen looks perfectly black. No tint issues.
[Huawei Watch] Skin1980:
Can you try the adb command posted on the page before this pls? Would be very helpful.
[Huawei Watch] dunjamon:
Sounds interesting...looking forward to seeing the results.
[Huawei Watch] wy1d:
Can you post a long exposure shot with an SLR on pitch black using the Watchmaker black watch face in ambient mode?

So far everyone who said they didn't see it did in fact have it, just found their eyes were less sensitive than others.
[Huawei Watch] Skin1980:
That's what I think too. But since 2 model of display are present in the source, I want be sure, that's why I need the adb thing.
[Huawei Watch] wy1d:
Ooooooh. I have two watches. Tomorrow when I'm back, I'll check to see if my second watch also has the AUO screen. They both have red tint issue.
[Huawei Watch] wy1d:
Does the source tell you what the other model number is for the other screen? I may ask Huawei to send me a watch with the other screen to compare with the screen I have.
[Huawei Watch] Skin1980:
sure:

edo rm67160 hvga video mode dsi panel

BTW i tryed a lot of things with suzook, also i set the red to 0, the glowing is there.

I dont know whats happen on the display but without a device to test with i will stop here.

Later or tomorrow i will post the kernel with root init.d and busybox so you can experiment all you want.

Have a nice day
[Huawei Watch] wy1d:
I was afraid of that. Thanks for all your help. I would love to know if it's affecting both displays. Right now I'm thinking it's hardware related so I'd be surprised if both are doing it. Would be nice to get a long exposure picture and dmesg from someone with the edo RM67160.
[Huawei Watch] swngdncr:
I could do the long exposure, but you guys lost me on the "edo RM67160" and related tech talk... -cjr-
[Huawei Watch] swngdncr:
Here is a pic of mine, created a black watch face with pujie, but you can still sed I think it is the date, and the bright spot in bottom corner is the tick of the second handle. I didn't bother getting rid of those as you can see the red tint just fine.
[Huawei Watch] suzook:
EVERYONE should be sending these defective watches back. We need to send huawei a message. DONT accept a defective device.
[Huawei Watch] swngdncr:
A bit of a cross post here, but for those now on the Huawei site. I did another exchange on my watch today when the HRM completely froze. Was hoping that 3rd time would be a charm. No such luck, but,

this watch does not have the red tint like the other one

. I've checked a couple of times using the identical watch face I made up and used on the last one. Yup, no red tint discernible.
[Huawei Watch] Skin1980:
Could you check the display model?
[Huawei Watch] swngdncr:
How do I do that? (I'm not a real geek, just a wannabe..:) -cjr-
[Huawei Watch] Skin1980:
You can find the how to on the page before this.

Adb shell

dmesg | grep panel

This must be done after the boot
[Huawei Watch] iggdawg:
So at this point does this look like something that can be fixed in software or is it straight up bad hardware?
[Huawei Watch] suzook:
I would say 99% sure its hardware. If this is true about the Non faulty screen, this would be Great news.
[Huawei Watch] wy1d:
Would love if you can post a long exposure with a black watch face and check the panel type by connecting with adb and running dmesg like skin1980 mentions.
[Huawei Watch] wy1d:
Checked a second watch I got from Amazon. It also has the red tint and is also AUO RM69080:

<6>[ 1.096918] mdss_dsi_panel_init: Panel Name = auo rm69080 hvga video mode dsi panel

Really want to see if users reporting no issues have the other panel.
[Huawei Watch] suzook:
Im still not sure there really are any that dont have the issue.
[Huawei Watch] wy1d:
Agreed. Still curious about this second panel though. Would love for someone with one to post it up!
[Huawei Watch] iggdawg:
That's really a pity. The tint thing is one of the few things driving me away from this device and towards a Gen2 360. I'd be fine living with it for a while if it was something software could fix, but I dont want to be stuck with something perma-broken =(
[Huawei Watch] suzook:
Why not a lg urbane? Its a great watch with great screen
[Huawei Watch] swngdncr:
Can't get the debugging to work. I got it set on the phone fine, and enabled on the watch. But, It says "host: disconnected" and "target: connected". Also, I haven't a clue where/how to run the adb commands as instructed below. It assumes I know how to run an adb command. Do I run adb devices on my computer? I'm on a Mac, so how do I do this? From Terminal?

---------------------------------------------------

Your wearable should show up as localhost:4444 when running adb devices. To run any adb command, use this format:

adb -s localhost:4444 <command>

If there are no other devices connected over TCP/IP (namely emulators), you can shorten the command to:

adb -e <command>

For example:

adb -e logcat

adb -e shell

adb -e bugreport
[Huawei Watch] wy1d:
You can do it via Bluetooth with your phone connected via USB. You'll need to start with "Minimal ADB" and install that package. I'm not sure if it works on Mac but if not you'll probably need to download the Google Android SDK.

Once you get adb installed and the drivers for your phone and phone being recognized with "adb devices", you'll need to follow the Bluetooth instructions to map your watch port on your pc and then connect, then shell into it. So after those 3 commands you'll be at the watch she'll and can run the dmesg command. I'm not at my PC at the moment or I'd copy paste them all here for you. I'll see if I can do that tomorrow.

Have you been able to take a long exposure shot? Do you have an SLR?
[Huawei Watch] swngdncr:
Oh yeah, I've got the camera gear, but with a fast lens, it doesn't need to be that long. ;) I won't be able to work on this again for a while. We are in the middle of home improvement project and other stuff tomorrow, so not sure if I can get to it tomorrow night. Maybe someone familiar with Mac can help with the Adb tutorial. I can try in Parallels later if it is too much of a hassle on the mac -cjr-
[Huawei Watch] iggdawg:
I mean, I'm guessing at the end of the day if it is bad hardware and cant be fixed in software they'll let us RMA it. Considering overlooking this issue and getting an hwatch anyways. Am I being naive or is this a reasonable expectation?
[Huawei Watch] suzook:
What if they claim there is no issue, like lg did with the oversharpening issue on there lcd's??? Why buy a defective product? Makes no sense, but hey, its your money.
[Huawei Watch] iggdawg:
That's totally fair. I do appreciate the counterpoint. I'm on the fence, and thinking in a vacuum is no good :).
[Huawei Watch] wy1d:
This is what I've been told by Support. Personally I want to get some understanding of the scope before I'm outside of the return policy. It's an expensive watch and I want to make sure they agree it's a hardware issue and honor the RMA.
[Huawei Watch] wy1d:
Agreed. On my F1.7 M4/3 I only need half a second or so exposure to really capture it. What camera / settings did you use in your picture?

I have a MacBook but I've never used it for adb - have always used windows so parallels would be the easiest due to the walk through already being there. I'll look into seeing if there is adb and drivers for Mac though.
[Huawei Watch] swngdncr:
Sony a7ii f1.4 1/3 sec
[Huawei Watch] iggdawg:
This is my exact sentiment on it.
[Huawei Watch] wy1d:
Yep. That's serious business. With the full frame at that f-stop, I'm sure you'd show some red if it was there. Just for double confirmation, can you snap one at a full 1" in pitch black? You don't have to post it, just verbally report if it's still clear of red (definitely trust your word with that kit).

This is the first picture I've seen that gives me a glimmer of hope. I'll post something this afternoon regarding what to do on Mac so we can see what panel you have.
[Huawei Watch] Skin1980:
Try with this

https://code.google.com/p/adb-fastboot-install/
[Huawei Watch] wy1d:
This link actually contains an older 1.0.29 version of the adb bridge. Will need to have 1.0.31 or newer in order to support RSA handshake in 4.2.2+ Android devices.

Instead, use the zip attached.

I updated the install script so it should work great.

[MENTION=689863]swngdncr[/MENTION]

Here are full instructions to do this on Mac. It is MUCH easier than on Windows (no driver hell to deal with!). Thank you for asking me to look at this because I will never use Windows for adb again.

Install ADB on Mac

1. Download ADBforOSX.zip attached.

2. Unzip and navigate to Android/ADB-Install-Mac.sh. Right click/TwoFingerTap on ADB-Install-Mac.sh -> Open With -> Other... -> Utilities -> Terminal (you'll have to change the drop-down box to Enable: All Applications.

3. The script will request sudo access to install. Type your password and you are done. Close the terminal Window.

Enable ADB Debugging on your Watch

1. On watch, go to Settings -> About and tap on the Build Number 10 times until Developer Mode is Enabled.

2. Back out to Settings -> Developer options and enable ADB Debugging

3. Put your watch on your USB charging puck and connect it to your Mac.

Connect to the Watch from the Mac

1. Open a new terminal on Mac and type adb devices A prompt will pop up on your watch asking to allow Debugging on the computer you are connected to. Click either "Yes" or "Always allow Connections".

2. You may have to type "adb devices" again after accepting the prompt but at this point you should see your watch listed as a device:

$ adb devices
List of devices attached
MQB7N15919000393	device

3. Shell to the device by typing adb shell and you should get a shell prompt.

$ adb shell
shell@sturgeon:/ $

4. At the shell, you can type dmesg | grep Panel to get the panel output.

$ dmesg | grep Panel
<6>[ 1.100327] mdss_dsi_panel_init: Panel Name = auo rm69080 hvga video mode dsi panel

Please post your dmesg output here!
[Huawei Watch] vvveith:
I was watching Poltergeist last night ? in a pitch black room, during an interruption I glanced at the watch and sure enough could see the brownish hue on a complete black face. Upon watching closely I also noticed the watch face dim and brighten before switching to ambient. Called Google and reported observations and my concern, without hesitation they RMA me anew one to try. They said if I noticed a problem, either take refund or exchange for different brand. I'm hoping the new one is free of defects because this is the best looking watch imho.
[Huawei Watch] wy1d:
Can you adb into the watch and check the display type with the instructions in this thread? I'm trying to gather info to determine if the red tint is affecting just one of the two screens types that are possibly in this watch.
[Huawei Watch] PookiePrancer:
Mine has the red tint, so I've started posting on as many reviews as I can to raise awareness of this issue. I doubt it's isolated, and kudos to the discoverer. It's subtle, but very real.
[Huawei Watch] Techniques:
I have the red tint. rm69080 display type.
[Huawei Watch] wy1d:
Thanks. You can also contact Huawei and open a case. I have one open and have been emailing daily to get an update. Nothing yet.

Can you use the instructions in this thread to connect your watch to your computer and use dmesg to check the panel type?
[Huawei Watch] swngdncr:
Wyld, thanks for the detailed instructions. Very helpful, but not getting any love. Everything works fine, i get the list of devices, do the "adb shell" command and get the shell@sturgeon:/$ reply, but when I type in "dmesg | grep" Panel, I get nothing. ( I blanked out my name on the below copy from Terminal). Tried it a few times, same result every time. -cjr-

[Huawei Watch] Skin1980:
In Unix panel is not the same as Panel.

Please try again, after a reboot, and write panel instead of Panel ( no capital letters)

Edit: just realized that you tried that, sorry if I didn't noticed that. Try after a reboot pls, the dmesg can be overwritten if passed too much time from boot.
[Huawei Watch] wy1d:
Capital P will give the specific line we are looking for and lower case p will give the boot parameter which also contains the information. If you aren't getting any output, as Skin1980 mentions, it may have been too long since the watch booted. Try rebooting the watch then connecting with adb and running the command.
[Huawei Watch] suzook:
So the only guy with a non defective screen cant get the panel type???? LOL We are waiting on you!
[Huawei Watch] wy1d:
LOL! I'm wearing out my F5 key on this thread!
[Huawei Watch] wy1d:
Please open a case with Huawei by calling one of the global hotline numbers from this page:

http://consumer.huawei.com/en/contact-us/index.htm?tag=hotline

Last update I got from them sounds like they are denying there is an issue. I'm still waiting on the details but it looks like marketing rubbish that is denying everything and not honoring RMAs.
[Huawei Watch] Skin1980:
Pls mate, try it again!!!
[Huawei Watch] wy1d:
Oh man I'm so excited at this. Please let me know if you are able to try dmesg again after rebooting your watch to see if we can determine the panel type!

In the meantime, I'm going to keep swapping my watch hoping to get one without the defect. Should have a 3rd watch to try tomorrow!
