faulty light sensor on zte v970 - ZTE Grand X V970

Hi,
Got my ZTE V970 from etotalk a couple of weeks ago. I like it very much, but it has 1 big problem: the light sensor. In a medium lighted room it goes on and off like crazy, switching from full brightness to zero back and forwards. I am using the original rom.
Has anyone else with the phone this problem or is mine faulty?

Mine is only a little bit nervous in medium lighted rooms - but itis not that bad. Does't go from shiny to black in my case.
I have Brunos ROM on my V970.
By the way, does anybody know if it is possible to enable haptic feedback for the 4 softbuttons (Menu, Back, Home, Search)?

'Soft Buttons Light' app from market can help
not perfect but good enough

Or you can NOT set the screens brightness to auto...

[Q] Backlit buttons not working correctly

Ok,
So my home row buttons (Menu, Home, Back, Search) do not light up as they should! if the room is dark they will not work at all! and ive never seen them work in a dark room! However every day in the late afternoon when im in my living room and the phone is charging they will just light up! (at first i though it was a refection or just ambient light in the room so i grabbed the phone and ran into my closet and WOW they light up!) so i figured it was something with my settings so i reset my phone to new and still same problem, then said WTH and rooted and updated to 2.3.4 (best thing ive done with it so far!) and have the exact same problem... So then i decided to try another charge (brand new out of the box 1 day old!) and the lights will do the same and light up when its moderately light in the room but then they wont turn off...
So a chat with samsung and they tell me that these phones dont have that feature! so off to verizon and lets test a few more devices!!! and what? at some point they lit up also in inappropriate lighting conditions, so after puzzled VZW people i consult samsung again and they tell me yet again that the featured isnt offered on this phone, so my guess is that its a software flaw?
any ideas?
anyone having lighting issues?
thanks
Wow, that's a lot of exclamation points. I don't know what you're talking about, mine work fine

Pictures
Here are 2 pictures that show what im talking about, i will try to get a few more
Odd, works fine for me. Is it possible that you have a screen protector covering your light sensor? In the day time the back lights are off, then if I cover the light sensor they come right on.

The light sensors (which controls auto brightness and the backlights on the hardkey) is broken in the kernel for Gingerbread..
If this is a huge issue for you you might want to consider going back to Froyo

But he said it happened with the new phone and the verizon display one...?

It might even be broken on the stock Froyo. All the people who said it's working fine for them right now are running custom ROMs, kernels, firmwares and all that jazz. Maybe it was fixed through one of these custom updates. I dunno.
I just got a brand new Charge (thanks to the Fascinate swap program).
The bottom buttons do not light up. This is fresh out of the box.
I also do not see any way in which they would light up - the icons appear to be painted on to the physical buttons. No underlay for LED backlight.. but I suppose there is one if custom ROMs allow for it.
Which I will know shortly

there is no screen protector or case on either of the phones, and both phones were cleaned well to make sure nothing was hindering the sensors.

The problem is not only to the one that is rooted and flashed but also happens to the 2 at verizon that i inspected (brand new out of the box) and the 2nd one that i have that is also brand new with no mods

I think that the kernel for this phone was just snatched and quickly edited (by samsung) from another product and this is one thing that they havent been able to fix and figure out, because the woman at samsung told me
(Ruby: As your phone has physical keypads, there is no light feature available for keys.
Visitor: the small row of buttons (4 to be exact) at the bottom of the phone should be back lit in low light situations, however they occasionally light up but only in moderately to brightly light rooms
Ruby: I am sorry, there is no feature available on your phone.
Visitor: im sorry but i can prove that this phone does have back lit keys
Ruby: I am sorry, your phone home key rows do not have light option)
but we all know that the button do actually have a lighting option and samsung is just trying to delete the function but isnt 100% successful..
I don't know what to say, they work properly for me. This includes when I was fully stock EE4, as well as now (deodexed, rooted ROM, PBJ kernel, voodoo enabled).
droid charge doesnt have backilights in the keys.. wth are you all talking about... no wait there they are! barely. what th! where did they go again?
Stock froyo from the factory... Daylight = button lights off; sensor covered (night) = button lights on.

Notification led FAILS

Hello everyone,
I'm thinking to buy this very good devices but I read on some italian sites that there are some batch that have notification led bugged.
I'm explain better: they told that the led is shifted from the normal position and isn't so visible as other batch.
Anyone of you have this problem?
BR
nope, mine is at the right position and works well

Thanks.
Can you do a photo so I can compare with the one that I will buy today?
Will seems strange but on internet there aren't any photo of the one s notification led.
For me hte LED, comparing to the Desire is less noticable
I don't know if this is a bug or a feature, but the led is definitely too back behind the ear-piece net.
Just got my grey one s yesterday so not sure what is normal what is not in terms of notification light.
My light is located at the second row of the speaker holes, the 5th hole from the left. it is yes quite small compared to my incredible s, and during daylight, you have to be close to the phone in order to see it.
Is it normal?
This is my same location of hte led as well

my led is in the same location and it is much less visible as compared with my 2 years old desire...
The problem is not where is the led, but the fact that notification is still buggy after update 1.78.401.2: the other morning for example I had 3 emails but there was no led blinking. Others too reported led not working or working just for the first 5 minutes...

I have the opposite problem. My LED flashes for new emails, but does not stop when I access the mail app! (Still on original 1.53 base).
Have some problem.
LED blinking for a few minuts and after don't blinking
Mine is just fine.
Mine was useless. You can't even see the led from the sides,only when u look pretty much straight at phone. Led is behind the speaker grill.

Also coming from Desire, this is a topic of concern for me as well, since I usually look at my phone from an angle when it isn't in my hand...
Same issue with the One X

good and cool idea as far as design goes, but most definitely not good for notifications
Mine is international unlocked, but with french CID. The led is too down and catches up just the first row of holes on the grill.
I must say it's completely unusable. I'm looking for a way to hardware fix it with some light conductive material.
Maybe a software patch to boost up the LED current will be also needed.
On HTC Mozart it's also under the speaker grill, but it's way to bright compared with the One S one.
mine works except I notice it only blink for like 5 minutes and turn itself off.
Mine is kinda useless, since it's almost impossible to see it unless you hold the phone in your hands...

Problem with the backlight

Hi! Two days ago, my phone dropped in water , i put them immediately in rice until today. When start it with the power button, i felt the vibration and i hear the open sound. But the screen remains black... but i discover that it was just the backlight because when i watch the screen under a lamp i can see the interface and slide between pages... but its very dark. Is it possible to change this backlight? or just wait few other days to allow time to dry fully. I welcome your suggestions! thanks

When there's water involved, IT's hard to know exactly what damaged. Could be just stain on the ribbon connectors, a burned fuse/diode/resistor (all of them micro sized) etc.. or just the LCD's backlight damaged entirely.
Keep it on rice for more time. I would make the battery to discharge to 0%, But it's also more recommended to keep the phone OFF. Only my friend LUCK knows.
To change the backlight, the whole screen needs to be changed.
Backlight died on me. Possible moisture.
First, it was on boot loop (on stock rom)
i went to restart it (holding power button and volume down)
then the screen turned bright white, restarted it and then the backlight died, dismantled the phone, now still in rice, also happened on 2nd April.
Any help is greatly appreciated.

Took it apart down to the Screen (not the screen layers), left it in rice, works like a brand new now. Cheers.
I just replace all the frame and lcd for a new on my nexus 5, but the problem was still there... no backlight, i can see a little bit the screen, but it's very dark... do you have any idea for try to repair this, because now i don't think that it's the screen but more a motherboard or power problem for the backlight :S
exactly same problem here
nexus 5 phone dropped in water.
Backlight went out permanently - rice didn´t help.
Can see the display working using a flashlight - so rest of the phone seems to be working ok.
Just pruchased a new screen, put it all in and still the same problem: display works, touch works, backlight is off.
So it seems the backlight part of the display receives no power - anybody has an idea how to fix that?
thanks
I have answer to this!
I have had this problem like 3 months now and i finally fixed it.
Basically what i did was that i bought a broken nexus 5 (only the screen glass was broken) and tried to swap every part one by one. The one that was not working was the main dock!
It is a cheap fix, like 10£ on Ebay.
I am writing this post because anyone else haven't.
I hope that someone sees this.
I now copy this message to all other threads so people can fix their nexus 5's
PS:as you can probably tell English isn't my first language.
Hello! I am having the same problem. The cell phone fell to the floor and the next day the problem began. The display is not broken.
What are you taking about when you say "main dock"? Motherboard aka mainboard?
Thanks!

[Q] Screen Was Fine, Suddenly Turned Green and Faint?

Hi,
My Nexus 5 was working fine, and hasn't been dropped/damaged, but the screen has suddenly gone green and very faint. It still works but I can't figure out what the issue is. My guess is hardware?
When I say green and faint, I don't mean just a little bit, I mean a green/yellow hue all over the screen, and faint like someone has applied super high contrast in a photo editor.
Any ideas?
Phone is stock, not rooted or modified in any way.
Thanks
Leakage?

Sorry do you mean light leakage?
The phone now has yellow borders a few mils thick on all four sides, in addition to a green hue.
Perhaps
Still under warranty?

I have the same issue as of a week ago. Except mine is pink borders and a blue tint. It was fine one night, plugged it in to charge at bed time, took it off the next morning and it was stuffed!! After a day it came right but then stuffed up again a few days after that.
I'm guessing its the display but don't know why. Looks like you can get Chinese replacement ones for about 60AU$, but the procedure looks pretty full on.
Just to update, as per poster above the phone has now returned to normal after a few days. Very strange. Factory reset, cache clear etc etc didn't work, just one day started working again.
Have the same problem
I am also having the same problem. I was charging the phone on my laptop. I took it out and suddenly the screen had a bluish - pink tinge - prominent around the corners but affecting the entire screen.
Did you find any solution?
Yep as above it just righted itself within a few days. Very strange, never seen a phone have an apparent hardware issue that's unresolved by factory reset etc then just miraculously lose the problem...but that's what happened!
It definitely has to do with the display.
i changed my original display screen as it was broken with a cheap one and since then it always gets green and pink tint while charging. After sometime it turns to the normal color.
Same problem pink/blue tint over night
I bought a used nexus5 just 2 days back but it looks stunningly scratchless so its probably refurbished I guess. Any how, I put it on charge the next night of purchase with a heavy duty charger that came with my Tablet its rating is 2Amp. In morning the phone had this blue/pink tint.
Is it a problem or will it go back as most people are saying? As long as I keep on using proper charger will it come back?
OR
Should I go back and strangle the seller...?

My phone restart at least 2-3 times per day, every day, since the day i got it.
i'ts not even the same thing i do when it restart. sometime i just open my phone and it restart.
I have spoken with my provider, and they won't do anything until they see it restart when i'm at their shop... but you know, i can't stand in their shop all day long!
i don't think it's the same problem as you, but some of P30 really have a restart issue!
Also my P30 since when I updated to EMUI .124 restart 2-3 times a day. It also sistematically freeze during Antutu stress test (maybe it help you to show to your provider).
I just send mine to be replaced, but I'm worried that also if they replace mine nothing change...
Been using almost 2 weeks on 124. So far no reboots and just ran antutu stress test successfully.
No issues in that regard to my UK purchased device. It's been solid as a rock so far with amazing battery life also.
Maybe there is a lot of p30 with this kind of issue. Let's see how will go the new p30 that huawei will send to me as a replacement.
No problems on my end, except for a blue tint on the recents window. Using a third party launcher. Removing/ disabling Huawei Launcher gives you an older (and in my opinion uglier but better) recents screen back without that issue. Everything works fine so far but they really need to tone down their bloatware. That's the main reason why i dislike Samsung and Huawei.
only one light flashes. only the right thing works for you, how is it?
Fingerprint sensor. Works slow and flashes frequently, Mine got stuck two days ago and even after couple of reboots was still not recognizing anything. Then started working again...

Let us know if it works after replace.. I'm worried that there is a sw incompatibility with something I installed and that nothing change when I will have the new p30. It can happen that one phone have issue, but I already heard 4 case with the same issue!
On Monday I went to the beach with my family, took the phone out to take some snaps of the scenery and the with 3 x zoom, lens had the sun directly on it and the screen started to flash but only when sun was directly on the lens, doesn't sound right to me so am thinking of getting it exchanged. Anyone else had this issue?
I sent my p30 to huawei assistance and they returned back my device with issue not solved. Phone still freeze sporadically.
Hello everyone, i have a strange bug om my p30, i bought my phone a week ago and i'm sure video recording was fine at the beginning, then i applied .124 update and now when i try to record videos it just stop after 1 second, no matter what resolution or format i choose, it happens with back and front camera. I already wipe cache and data of the camera app, but no luck. Videos works fine with other camera apps like open camera etc.. . I spent a week for fine tuning my new phone , so i don't want to reset all. Someone have any other suggestion? Thanks

Did the whole screen flash or just the picture preview? This doesn't sound abnormal to me. The little pixels of the little sensor fill with light super quickly, so of course pointing it directly at the sun will make them overflow with photons and just return a mostly white image

Talking to Huawei support at the moment to fix the blue tint (and maybe also WhatsApp notification/ bad video playback performance) issue. They told me they'll reach out to me today.

I have the same problem with my P30 switching back on when charging - I've only been able to overcome this by inserting the charging cable first, then powering off. Not sure about your other problem as my display brightness is always set to auto.

Seems like they fixed the flashing bug with the latest update (.153)
I'm still waiting for it (.153), but as I try to find some logic in it's behavior I guess they tried to make it kind of notification light, but it seems to be unsuccessful.
