Screen flickering on lowest brightness - ZTE Axon 7 Questions & Answers

On the lowest brightness setting some parts of the screen flicker and the gamma seems easy off.
Does anyone else have this issue or is it just my unit

Edit: everything is fine when I turn the brightness up a bit and the screen is perfectly fine then.
Edit2: it feels like the a2017G isn't using the panel for the lowest brightness setting but just alters the gamma curve to make the screen look darker.

Fun fact: it's the charger that causes this for me

This happens on certain parts of the screen - when brightness is low - while charging for me too

This is happening on my unit too when charging. But only seems to happen at low brightness. Funny enough it didn't happen on my first gold unit but does on my second grey unit. Hopefully it doesn't develop into a bigger issue...

Me too. Only when charging, you'll see banding/snow.

Switching to a non quick charge charger greatly reduced the flickering ( might even prolong the battery life and it's nbd if the phone needs a few hrs to charge overnight )

I haven't noticed that on my A2017G. I'm on one of the latest batches I guess. It came pre-installed with the B02.
Give me a few steps how to reproduce that issue and I will see if it happens.
Also I'm curious does this happen with the A2017U.

I have a ZTE Axon 7 2017U and it happens to me too. On my phone the flickering happens when I'm on the lowest setting and it seems that the brightness/gamma flickering is only from the middle of the screen and below, the top part is fine. But to be it happens on the lowest setting whether it's charging or not.
It is rather annoying but same as you guys my solution is to bring the brightness up a little.
I don't know if this is due to the life of the screen fading or an incompatibility on the system that causes the flickering.

my new nexus 4 has a yellow tint

visible on grey background, so it s annoying in settings :s
Is the warranty working on that ?
Can franco kernel solve this issue ?
Mh if you have not already broken your warranty I would send it in. Faux kernel can solve this problem and I think also Franco but it's not the same. It seems that your device has a strong hardware tint so I think it'll look better if you send it in

hmm what do you mean by it's not the same ? (it's complicated for me to send it now, maybe in few month. )
i have the warranty but if i flash the phones, i can go back to stock isn't it?

To be honest I don't know about warranty maybe someone here has gained some experience with warranty?
It's not the same, in my opinion because it seems you device has some abnormal "heavy" tint so I think you can neutralise the yellow tint but I don't know to which degree you will be successful, because of the heavy tint.
I'm sorry it's hard to explain.
You can definitely make the display look more natural and better balanced but I don't know how strong the tint is, because most Nexus 4 have a way to strong blue color.
Maybe it would help if you could take a photo of the display with a nice white balance and some comparison like a white paper next to it (and a clean white color shown in the display) so that we can see more clearly how strong the tint is.
But if you cannot send it in now I think you will try it out. And I don't know if they will take the phone back after a few months because of a problem which exists since you bought the device...
But I'm really unexperienced with warranty.
Maybe someone else could leave his opinion?

in my opinion, the yellow tint is not heavy...but it gives a strange colors in parameter and on grey in general. The white is quite good i think, maybe a little bit yellow, but definitely not blue.( the screen also have average vision angle in terms of ligth (not colors)is that normal ?( it s not a very important thing)
by the way, i will try other kernel if i can't adapt to the screen.
of course i will try to make a photo, but i only have my computer for that and i don't know any software ofcapable taking photo with the webcam XD

Na it's OK if it's not too heavy you can neutralise it, but you won't find a preset for a too yellow screen so you will need to calibrate it on your own with gamma and stuff so it will take time but it's possible
I would take faux kernel he has one general app and then one separate display calibration app
Average vision angle is normal
EDIT: Franco has such an app too, Sry didn't know. Only gained experience with faux and I'm happy with it

slim bean rom can solve it too (compared to JRxxY stock), seems like including color tweaks
Did you try to fix it?
Did you manage to get rid of the tint?

yup mine had yellow tint too but prolly not as bad as yours, with color calibrations in franco kernel, its back to iphone IPS colors now!

Display of Black colours

Hi guys.
Just a Quick question:
I compared the screen colours of my Z2 with my old Samsung Galaxy S2 using the app screen test.
There I noticed, that black on the Z2 isn't really black while on my S2 black is truly black.
Is that normal?

Its normal as far as i know Samsung phones use Super Amoled screen which has darker black while Sony use IPS screen technology has less darker black ,, dont worry its totally normal
It can't really be darker than the screen itself, because black is absence of light, which means the light sources are turned off when displaying black.
The color black will be as dark as the panel.
Well the panel is definitely much more black when it is turned off.. In the end the black white contrast on my S2 is much better
When I run the screen test app, when black is being displayed, the screen isn't off though

IPS is lighting even when display black, compared to AMOLED where every pixel has its own led diode so when AMOLED display black, its pixels eventually turn off. Thats why..
Different display technology, both have their adv. and disadv.
On amoled displays black pixels turn completely off, which is why it has so good contrast.
this is completely normal, because the superamoled panel have isolated pixels. the black in amoled panels is literally black, no light emitted, only the reflections from screen. in a complete dark room, the screen blackness would be the same as the room. LCD panels cant do that, the best ones can do something like 0.08cd/m2 of black levels, this mean that the black is actually greyish, while super amoled can do 0cd/m2 meaning infinite contrast. according to reviews xperia z1 compact have a black level of 0.44cd/m2, and while the z2 has a better screen, the black levels should be around the same
thx for the explanations.
Light emitted always needs battery consumption so I would assume, the amoled screen is especially with dark colours more battery saving, then the lcd screen, right?
Yes it is

[Q] Z2 owners - how's the screen's visibility when outdoors??

I'm thinking about getting this phone but one of the major concerns I have is how visible the screen is when using the phone outdoors and the sun is out. I saw a review that said the phone was unusable outdoors because it doesn't get very bright but I want to hear from actual owners.
Phone is more than bright enough for me, problem is that its quite reflective. Im coming from one x, so only can compare to it, and its better than one x.

It's clearly not perfect in direct sunlight; you have to make an effort to read the screen.
Despite this particular situation, the screen is perfectly usable outdoor.

Yup it's the worst thing about the device it can be totally unusable in the sun I have just bagged a smartwatch 2 with a metal strap for £50 so that will be used as well as the z2

I mean, no phone is usable in direct sunlight but there are varying degrees of visibility so it has to be relative to what other phones are capable of.

Check this, seems acceptable for me no deal breaker here as some may suggest

I find the screen to be ok but I can see lots of reflective white dots when in direct sunlight, very annoying.

For using in direct sunlight, Galaxy S5 is the best ever. But that one sucks battery. Z2 somewhat not deliver more brightness in direct sunlight.
I actually liked Z2's screen better than Z1's & ZL's under direct sunlight. You can check the third post at this thread

On auto brightness, it seems fine to me. Average I suppose? I can see it just as well as my moto x and I never really had a gripe with its visibility. Only thing I noticed that could have brought this up as an issue is off angle viewing it becomes far less visible...but why would you use it off angle? I live in south Florida BTW, so there's no lack of sun.
Much better than I thought. No problems even under direct sunlight.

I come from a Szajsung Galaxy S3 and I really love the Z2 screen. Under direct sunlight only the reflections are a little bit annoying.

Pink tint in white background

Hi guys.
I'm a Note 4 user.
I love It, but using white background i find a little area in the low half screen not so white but white /pink.
Tilting the screen white is cold.
It's normally?
Erica Griffin in Note 4 Review spoke about this problem in her video.
Ps. Why "Reading Mode" is missing in Note 4?
Same here. I have seen a lot of N4 - an they all had a pinkish tint on white backgrounds. One more, one less.
Gesendet von meinem SM-T325 mit Tapatalk
So this is not a problem?
Of course this is a problem. But as I said before - this is the way nearly all the N4 screens I have seen look like. I fear you have to accept it.
Try changing screen mode
Adaptive or Cinema makes it bluer. But having half the screen colder like that isn't normal.

Uneven screen color temperature

Just got my Android Yoga Book. Fantastic piece of hardware. The best tablet I put my hands on in a while.
However, I do notice uneven color temperature on the screen: right side (where YogaBook logo is located) is slightly colder (looks more bluish), than the left side (which is hence warmer or yellowish). It's not huge, but I can definitely notice. It's most visible on the white background. I'm trying to figure out, if I can live with it...
How are your screens?
I am pretty picky, and almost on all recent devices (MSI laptop, Moto X smartphone) I had to go through a couple of RMA exchanges, until I was given a screen, that satisfied me... I saw such issues even on the most expensive iPads, but my girlfriend says I'm just crazy...
girls are always right, period....
My screen apears even in terms of color to me. However I am not too sensible - did you check with different ambient lighting?

Yeah, I can notice unevenness at any ambient conditions. I will try to exchange my tablet, as I've been trying to ignore this issue for several days, but it bugs me every time I look at the screen.
I can't see any variance in color temperature on my Yoga Book.
I have also noticed this on my Yoga Book. It is a very subtle issue and I have to focus on it to actually notice it.
Its on right side as OP said so probably a factory/construction issue.
mine is ok at the moment. Got mine from UAE.
