[Galaxy Tab S2 Q&A, Help & Troubleshooting] kms108:
Should be ok, got this from QUALCOMM site.

Q2: My device doesn't have Quick Charge 2.0. Is there a way I can get it?

A: Unfortunately not. Qualcomm Quick Charge technology is designed into a product by the manufacturer. The good news: there is a wide and ever growing list of phones, tablets, mobile routers, and applications that do support Quick Charge technology. Also, since Quick Charge 2.0 is compatible and interoperable, a certified adapter can be used with a non-Quick Charge 2.0 device, though the fast charging benefits of Quick Charge 2.0 will not be available. You can download a .pdf of some supported devices.

Problem

Start an app that uses GPS (such as Maps), and then use a root file explorer to look in /data/gps/ , you will see the file gldata.sto, but you will not see lto.dat. This contains long term orbit data used to speed up a GPS fix from a cold start. If you see this file, then the fix posted here is not needed.

Cause

If you enable logging and look in the log file, you will see a line like this: LBS: Error resolving address from bcmls2.glpals.com. I have no idea why it can't resolve the DNS, but this prevents the file from being downloaded. This address is stored in the /system/etc/gps_brcm_conf.xml file. You will see the following: LbsServer="BCMLS2.glpals.com"

Fix

Simply change this to the resolved IP address and it should resolve the problem. I have attached a zip that you can install from recovery so you don't need to make the modification manually.

I have tested this on P769. Please give feedback on whether this works for you, and whether this helps for other L9 models.

After test, working fine for me on P760 with cm11.

Thanks so much

Several /r/hwatch users are reporting a red tint on the screen even when it's supposed to be off (completely black pixels). Support tickets have been open but unfortunately there's no line to actually reach Huawei for support, only 3rd party call center (Knoah).

Are any of you experiencing this? Currently it seems to affect ALL Huawei Watches. See below for details.

http://www.reddit.com/r/hwatch/comments/3mcsdf/_/
[Huawei Watch] swngdncr:
Yup, did the test with a black watch face I did on Pujie, and I could indeed see a red cast when I went in a dark room. What would be the impact of this? It doesn't seem noticable except when you put on a completely black screen. When the watch face times out.. then it is completely black....
[Huawei Watch] suzook:
THIS is the reason my urbane looks better than the huawei! I knew something wasn't right with the screen.
[Huawei Watch] wy1d:
1. Ambient mode drains more battery than it should.

2. Risk of red pixel burn-in.

3. All images and watch faces are slightly more reddish than they are supposed to be causing it to look bad.

4. Dim faces on black backgrounds will have much lower contrast than they should making it difficult to read (like Wear Charge Widget)

5. For many, the Watch is their first Huawei device and first exposure to Huawei support which so far is proving to be pretty terrible. They have a 3rd party call center in the US (Knoah in Vegas) and no way to contact a Huawei employee directly to report the issue or understand what is causing it (is it hardware or software). What/if there is a fix. They have suggested swapping out the watch but so far all watches seem to be affected.
[Huawei Watch] suzook:
I bet most don't notice it. I knew something wasn't quite right as soon as I turned it on. I might not have noticed it if I didn't have an urbane.
[Huawei Watch] wy1d:
Same. I knew something wasn't right when I turned it on. Hangout contact images looked terribly over saturated and unnatural. And even in ambient mode, I could tell blacks weren't black like an OLED should be, putting out more light in a dark room watching TV. Huawei said it was only affecting a few devices and they'd swap it out but never did. So I bought another one overnight from Amazon and same issue.

Trying to raise awareness so Huawei will take it seriously because right now I think they are shrugging it off since they are the best reviewed smart watch.
[Huawei Watch] suzook:
It might be my first and last huawei product if they don't take it seriously.
[Huawei Watch] wy1d:
I'm wondering if the Nexus 6P will have same issue...
[Huawei Watch] suzook:
Strange, I was thinking same thing. Hopefully it does, that would get huawei's attention.
[Huawei Watch] wy1d:
6P isn't shipping until 1st week of November. I definitely don't want to wait that long for a fix! If I can't get a fix within my return window, it'll probably go back to Best Buy and Amazon.
[Huawei Watch] myke66:
Didnt you already return it and move back to the Urbane?
[Huawei Watch] suzook:
Keeping it till my 30 day return window is up. Hoping the issue can fixed in the meantime.
[Huawei Watch] tsells:
No Red Tint for me in ambient mode with all black face:

Here it is with watch face:
[Huawei Watch] dunjamon:
With that blank screen do you see the tint in a dark room?
[Huawei Watch] tsells:
No. In ambient mode it is pure black in a dark room.
[Huawei Watch] suzook:
Like in a pitch black room??? Something doesnt add up. You see no slight glow at all in a pitch black room?
[Huawei Watch] tsells:
There is no red tint/glow whatsoever in a dark room!!
[Huawei Watch] suzook:
or a "glow'?
[Huawei Watch] tsells:
No tint; no glow. It's pure BLACK.
[Huawei Watch] suzook:
What sw version are you running?
[Huawei Watch] brizey:
Odd...same experience. New watch is slightly brighter with the red glow, but the battery is crazy good. I was at 78% this afternoon after about 9 hours on about the fifth day having the watch. Projected by Android Wear to two full days. Going to charge it tonight regardless, but I am tempted to see if I can really make it to Wednesday morning. Always on, no wrist to turn on, other gestures on and WiFi on. I use SWapp to make the ambient dark (usually set it to 60) and have the brightness set to 4. Completely stock. Using a customized WatchMaker face with a blacked out background in dim mode.
[Huawei Watch] bailyc:
One thing that I have noticed is , occasionally, the battery will start to plummet very rapidly on the newest watch with redder tint. Like, 20%/hr. I think (but at not sure) that this is unrelated to the screen or tint, and is a bug with the Android Wear app. Around the time of the new watch, I had updated to the latest version. I downgraded today to see if (1) the sudden drain stops and (2) I still get the same performance. I really can't see why it would be related to the tint itself in any way.
[Huawei Watch] brizey:
I've seen that, too. I also think its an AW glitch. BTW, today, 10 hours, 78%, lol. I'm tempted to see if i can get it to go 48 hours.
[Huawei Watch] Motawa88:
Wow. This **** completely deysroys the purpose of a amoled screen.
[Huawei Watch] brizey:
It still gets better battery life than all of the other watches. It is REALLY dim...way dimmer than an LCD backlight. Its so dim you either need a camera or have to wait for a minute for your eyes to adjust to be able to see it. It's basically like 010000 instead of 000000. The green and blue pixels are still off. It is either a firmware thing where it does not properly set the red subpixels to zero, or some sort of leak in the transistors powering the subpixels. I think its the former because it is so uniform.

I am not sure how the interface to these panels actually work. I assume there is some sort of scale for the intensity of each subpixel. What I wonder is how they implement brightness. If I set a pixel to say, 0A0A0A, and drop the brightness to 50%, does the GPU send 050505 or does the gpu send 0A0A0A and 0.5 for brightness and the panel scales it back? I only say this because I noticed that the app SWapp Dark seems to be able to change the brightness of the red tint. What I am wondering is if the GPU sends 000000 and say 0.5 for brightness, and somehow that ends up as something other than what we expect: 000000 no matter what the brightness is set to.

Edit: I guess the sony also gets great battery life with the transreflective screen.
[Huawei Watch] suzook:
So this has not been fixed? WTF is huawei doing??
[Huawei Watch] MechanteMiette:
Losing customers… And also potential customers.
[Huawei Watch] tafo:
I bought recently a Huawei watch( from 2 days ago)..it has a red tint unfortunately:( I'm really frustrated! The HRM and battery is good, as I read this thread that its mostly a hardware issue.. I'm thinking to return it back
[Huawei Watch] tafo:
I returned the HW and i bought another one, i still have the same issue :(, but one thing that i did is i installed the RGB color calibrator for the nexus 6 (which is AMOLED screen also) i raised the red color... It showed the same tint on HW , however, when i turned the light off completely.. i didn't see the red tint?, which is the opposite if its compared to ambient mode on the watch ( in the ambient mode, brightness is zero and still red tint is seen on the HW), so this suggests to be hardware or software issue? It seems more likely to be hardware:(
[Huawei Watch] mike49:
Just checked my Huawei:

I was already wondering about the fact, that black backgrounds are still somehow illuminated, which should not be the case with an OLED-Display.

So yes, there are occasions when red tint becomes clearly visible, but not always. For example I have black watchfaces and black levels are great without any red tint. But when switching to dim mode, there is a black screen for a short period of time which has red tint then which makes me believe this is somehow software related.

But anyways, not turning black pixels totally off is a huge fault on this watch.
[Huawei Watch] tafo:
Yea thats what ive noticed, its still illiminated instead it shouldnt, another thing i have noticed today that when u apply a totally blanck black watch (using watch maker) and u r disconnected from the phone. U see the cloud ..as there is halo black color surrounding it and its good black color, where as the rest of the watch is slighlty red tint! So far im feeling it can be solved by firmware upgrade and i hope its not denial of a harware fault?)
[Huawei Watch] Outrager:
I wonder if the red tint is caused by the sapphire glass and the way it's illuminated by the AMOLED.
[Huawei Watch] 7t3chguy:
Sure, but this issue is happening when the watch face is 100% black, so all AMOLED subpixels should be completely off, so there would be no light behind the Sapphire Glass for that to occur.
[Huawei Watch] Outrager:
I wonder if it's because of the way Huawei is utilizing the AMOLED so that it's not actually 100% black. It's just a really dark grey. Just a guess.
[Huawei Watch] jakemog:
I just got the watch, i can see a super faint glow but cmon.. how is this even bothering you guys?
[Huawei Watch] tafo:
Bro ..its not the problem by the red tint as it self.. As far as i know that This issue will be worsen and will make burned pixels afterwards!
[Huawei Watch] jakemog:
Many OLED displays dont fully turn off there pixels, just see what happened with the galaxy s4. Galaxy s 4 had an oled panel that disables all the pixels which resulted in bad ghosting effect.
[Huawei Watch] wookie_666:
I bought my HW 2 days ago. I have the red tint issue, but not that bad at all. In a very dark room, with ambient mode on, I can just notice a red ghosting effect. Definitely nothing too severe to return the watch. And nothing like the photos i have seen on this post.
[Huawei Watch] foo:
I also have the red tint behavior. At first I could not see it, because it can be hardly noticed under normal conditions, but when using a complete black watchface the red tint becomes visible in a completely dark room.

I somehow think this is intentional.

I was thinking that it could be a preventive measure to even out burn-in or aging effects. As it's in the nature of most of the watchfaces that some pixels will be active almost all the time while other pixels are only lit occasional, e.g. while using the watch.

Even with the pixel-shift in standby mode I think that some pixel areas are much more used than others. This "red glow" could be a measure to even out this effect.

I don't know, just my thought :)
[Huawei Watch] tafo:
Wow! Nice to know that...i thought the opposite is true!

---------- Post added at 12:11 PM ---------- Previous post was at 12:05 PM ----------

I think the photos that were seen on forums was shot by DSLR cameras, that can decrease the shutter speed which permits to capture more light which in turn magnifies the issue , i don't think that camera phones or automatic cameras can capture the red tint easily.

---------- Post added at 12:13 PM ---------- Previous post was at 12:11 PM ----------

As jakemog told us about the s4 OLED screen, u have a good point of view! Also to add.. Its weired that HW was made in a premium way..so why they have faulty screens( unless they have bad quality control process)
[Huawei Watch] evaworld:
almost all amoled displays can't completely turn off the black pixels, my note 4 comes close to 100% black, like 99% black, my note 2 was almost gray, so yes i know that as i am a long time samsung user. anyway it us way better than lcd. the only thing that i am afraid of is the burn in, never had it on any phone but the watch maybe a little different because it is always on. i am changing the watch face every day to try to prevent this
[Huawei Watch] improvius:
I got bad burn-in on a Samsung S3 just from using Waze. So yeah, I am also paranoid about burn-in on the Huatch and keep rotating faces. I'm always looking for faces that don't have a lot of fixed elements, especially in dim mode. So far, Pujie Black seems to be the best one for minimal burn-in risk.
[Huawei Watch] MigotR:
Yeah, im using pujie black aswell. But is it safe to use always on screen mode?

[Huawei Watch] improvius:
Try this: For ambient mode, turn off everything except hour and minute hands. Then set the ambient hands to "Minority" and adjust the length so they do not go all the way to the center. Now you have minimal watch hands in ambient that sweep around the whole face but aren't concentrated in the middle.
[Huawei Watch] MigotR:
:( but i would prefer digital clock i ambient mode, do you have some safe setup for digital clock:)? I saw burn in protection in settings

[Huawei Watch] Lostatsea23:
I really hope this is fixed... Just bought this watch today. Absolutely love it besides the slight red tint.. Just doesn't look quite right.

Watch has been out 1.5 months... If no word from hauwei in a half a month I'll be returning this for the moto...

Extended return policy ftw.
[Huawei Watch] improvius:
I emailed Pujie about their setting, and this is the response I got:

Personally, I'd still suggest using the "minority" hands in analog as opposed to a digital display if you are really worried about burn-in.
[Huawei Watch] erikiksaz:
Got my Hwatch over the weekend from Amazon and I don't notice any red tint. I'm not going out of my way to look for it, though, nor do I really care to at this point.

And I wouldn't worry about burn in. I've had 3 LCD-based android wear watches thus far, and the hwatch definitely displaces the screen by a few pixels to prevent this burn in. I have yet to see any of the other AW watches shift the screen by this much. I just recommend putting it into theater mode when charging overnight.
[Huawei Watch] dieselboy:
I've just gone into the server room, left the light off and then booted up the watch. I cannot see any red tint. When the four coloured dots are moving around the screen, the face is very black. Pictures on the watch do not look red shifted either.

There's no windows in the server room, it was pitch black. I couldn't even see my arm holding out the watch in front of me. I bought mine yesterday.
[Huawei Watch] foo:
It's very difficult to see the red tint if anything is lit on the display, even a status icon may trick your eyes. I also thought I do not have the red tint issue, but when I used a completely black watchface for testing purposes with absolutely nothing on it, I can see the red glow in a dark room.

For everyday use this is not relevant to me as it took me quite some effort to even see it. With a normal watchface I'm not able to notice it.
[Huawei Watch] dieselboy:
If I have this red tint then I'm unable to see it. From what I understand and correct me if I'm wrong, the tint is there when there is power going to the screen but the screen should be black. I thought I also read someones post that they could see the red tint when first turning the watch on, and when using the watch normally.. May be some people are affected worse than others? As far as I can tell, with my usage and even going in to a ridiculously dark room - I cannot see a red tinge.
[Huawei Watch] foo:
yes, that's correct. It's more noticeable if the display is set to full brightness and the watch is not in dimmed mode. But even then I still do need a completely black watchface to see the effect.

Difficult to say. I personally believe that just knowing the fact that there is a red tint can push the imagination a little bit. :eek:

If you want to know for sure, install watchmaker pro (great app anyways!), create a new watchface with nothing on it and send it to your watch. Try also to avoid that an icon is displayed (disconnected, priority mode, charging, etc..) and set the display brightness to 5.

Do not make this test during daytime but at night when your eyes are adjusted to the dark or even better have a look at your watch under your blanket when in bed. I promise you, you will see the red tint easily under this conditions as well.

I'm convinced about it, because I was first like you, not able to see the effect at all and were glad that my watch did not have this issue. :D I felt a little disappointed when I figured out, that it also shows red tint. :crying: But then again, I thought: Why would I even bother if I can't notice it in real life conditions and felt happy again. :)

Of course, you could also just leave it and be happy that your watch "does not have this effect". :good:

(But as you are on XDA I'd guess curiosity will get you sooner or later ;) )
[Huawei Watch] myke66:
Did anyone notice if the recent update helped their red tint at all? I can barely notice mine to begin with, but it seems like it addressed the issue on my watch. I cant reproduce it any longer. Curious to see if anyone else had any improvements.
[Huawei Watch] siv517:
I've seen a lot of comments here and on /r/huatch wrt red tint. For once I'm thankful for red/green attenuation in my retinas. XD
[Huawei Watch] dieselboy:
[MENTION=236491]foo[/MENTION] - I just remembered that my brightness is set to 1. Even still I guess I should have seen the red tint at boot up? To be honest I don't want to see it, because once it's seen it cannot be unseen :) As you say, if it cannot be seen in normal conditions then it's not really an issue per se. It's definitely an odd one, because some posts are concerned about premature failure due to power going to the red pixels.

Sometimes ignorance is bliss though. Sometimes I would prefer to be a regular person just to enjoy the watch rather than notice tiny manufacturing imperfections and for that to disappoint me and reduce the fun factor. I bet people here can relate. This sort of thing has been happening to me as a kid and it can be frustrating.

Later today if I get time, I will try and see the red tint just so I can report back but my guess is that it will be there. I will try brightness on 5 and keep reducing the brightess to 1 and see if any levels in between switch off the red tint. I've not read anyone here trying this yet, so I am now wondering if this high brightness is a software fault that causes the red pixels to be left on.

Anyone agree with my thoughts?

At work I can go and lock myself in the comms room and turn the light off. Very dark in there.
[Huawei Watch] foo:
But remember, to see the red tint increasing the brightness will only be of advantage, if you use a completely black watchface, that's important. If you have shiny elements on the watchface increasing the brightness will make it more difficult to see the effect, as the contrast gets higher and your eyes are dazzled by the bright elements making it impossible to see the fine red glow.

So I guess there is no way around it - if you want to see it for sure, you'll have to use a completely black watchface. :)

If you don't want to install watchmaker pro, you may also use google keep. You can create a note with a black image in it and open it on your watch.
[Huawei Watch] swbf2lord:
I can't see it at all on mine. I've looked with several completely black faces and I don't see any red tint.
[Huawei Watch] dieselboy:
Ok it's there on mine, but it's barely noticeable. It took a few seconds for me to relax my eyes enough to be able to see it.

How to reproduce:

1. install Google Keep

2. Download the black image: https://upload.wikimedia.org/wikipedia/commons/3/39/BLACK.PNG

3. on google keep, click "take a note..."

4. add the black image that you downloaded above

5. save the note

6. open Keep on the watch and click the note which is a black rectangle

7. go into the darkest of all unholy rooms and let your eyes get used to the dark. Look at your watch.

What I see is a burgundy glow on the face of the watch screen. Put it this way, if there was text written in this glow against a pure black background, I doubt you would be able to read the text.

The watch face kind of looks like this image (although I think this image is a piece of fabric): http://static.tumblr.com/9c978fd985...h/tumblr_static_9242s28tmyw4gkkckwgk8swog.jpg

---------- Post added at 04:53 AM ---------- Previous post was at 04:37 AM ----------

It's barely noticeable, so much that it's a non-issue really. As someone mentioned already if you even have a pure black face with anything on the face that is not black, ie a logo or watch hands, then you would not be able to see the red tint anyway because it's that faint! . I think you could argue a valid RMA if you didn't want the watch any more. You could give a reason for the return that the watch is faulty because when you're in a dark room the screen on the watch has a reddish tint and it's not supposed to do it. But it's pointless getting another Huawei as it's how they're built if you did RMA.

I know the guys in the USA have different RMA rules. Here in Australia and also in the UK we get a mandatory 12 month warranty. Basically, if my watch screws up in the 11th month after purchasing, I can take it back to the shop and get my money back. Now I'm aware of the red tint, I'll be conscious of it. If the picture starts to change over time then I'll RMA the watch. By then there will probably be something better out anyway. If anything the red tint has given me the benefit of RMAing the watch and getting an upgrade.

- we used to buy Schneider TVs from the UK equivalent of Wallmart (ASDA) back in the day. The TVs were like 30% of the price of the LG / Samsung flat screen (when LCD TVs first become popular). But cheap = poor quality and they always used to break down around the 10 month - 14 month mark. We were lucky that the 2 we bought broke down just before the 12 month period (inside warranty). I had a friend who's broke down just after the 12 month period which was unlucky.
[Huawei Watch] Scott:
I agree. YOu have to work hard to see the tint. The tint is more like a glow and is probably about .0001 Lumens.

It has no affect what so ever on my watch faces / apps. I can ONLY see it when I am trying really hard.

I think this watch is great! :good:
