[Q] Broken LCD display

Hello,
I got a problem which I believe can someone with more experience help me with. My topaz got dropped on floor from arround 1 meter height and possibly on the display side. I didn't pay attention but when I looked on it after some time, I noticed black dots over almost half of screen. I posted image to this. It has irregular shape so I believe it's some liquid thing and not necessarily hardware fault. As my warranty ended 4 days ago, I don't think about sending it for repair. I thought about disassembling it and clearing the display from this stuff, but first I'd like to hear your opinion on this. If everything goes bad I believe new displays can be bought (although they're quite costy, so I'd prefer fixing it.) The display is fully functional other than that stuff on it, also digitalizer isn't broken and I receive right input all over that place. Colors inside that shape has a very light blue color tone when displaying white.
Dunno why, image doesn't display so here are plain links:

Lenovo ZUK z1 is worth or not

Hi,
I have read the comments in amazon and also seen the reviews of Lenovo ZUK Z1 indian unit.
i found there are some issues like :-
-near the home button right side led light is not working properly.
-there are some heating issues in normal usage also.
-it hangs when we are in a call and there is only one way i.e. reboot of device.
-i also found comments saying that there is much difference between indian unit and other unit.
According to specs the hardware is realy good in this price segment but still some comments are saying its not worth to buy it.
Can anyone suggests wether i should go for Lenovo ZUK z1 (indian unit) or not.

I'm fairly happy with my ZUK Z1! I myself dide any of the issues you described, though I did have a major battery issue which I had to get fixed. Much more detail below;
The capacitive buttons' LED lights are just small white dots - they are a bit dim and hard to see outside (I believe that's just the way they are on the device). Regardless they do work fine - though I personally prefer on-screen buttons (navbar), which is an awesome option on Cyanogen which I do use (together with the physical home button). Phone does not feel hot to me (compared to other Android I tried - such as Sony Xperia Z3 Compact and LG G4 which did get confidently hotter). Calls work fine. I have no experience at all with the Indian version, I just had the International version with Cyanogen OS.
Now the problem I did have was that the battery my device came with was screwed up. The phone would turn off at random times and often display inaccurate battery percentages (e.g. fluctuating percentages, or phone displaying 1% for hours). It was really bad, a serious fault. Thankfully I was able to get it fixed for free thru warranty - since I bought it from a local store with 1 year warranty coverage (which was extremely useful for once). They replaced my battery for free and now it works great!
So that being said - there is indeed always a risk of getting a device with a hardware fault. Budget devices like this may be more prone to QA issues but remember that devices of any type or price occasionally have unit faults like that. Also keep in mind that people who have these issues are more likely to shout online than people who don't.
Overall though - I am quite happy with this device. It is fast and snappy, the battery life is indeed very good (lasts me a day and a half of fairly heavy usage) and I also like the fingerprint sensor (though I've had some mixed results with it. My tip is to make sure you initially scan your finger as best and fully as you can). I like the stock+ Android feel with Cyanogen OS (though Cyanogen are taking their sweet time with the Marshmallow update for this device! Though there are good custom ROMs for this device including CM13). I can recommend it.
If you can get it with warranty I say it's really a good choice, especially as a decent warranty can remove your worries. If I'd consider another device it would Xiamoi Redmi 3 Note Pro, which has similar specs but with a newer, better more efficient Snapdragon chip. There is also the ZUK Z2, but I think it's a shame that it has a smaller battery.

It's a decent phone but I wouldn't recommend it. A lot of people have problems with the home button (mine included) the fingerprint scanner doesn't work anymore. Cos has some nice features but the security patch is from last month and still no word on when we receive marshmallow.

My 2 cents, do yourself a favor, forget this phone unless it's free or very good bargain, it was promising at the start, end up as nightmare for most owners, just read some of the thread, every components has some issues, sound, GPS, home bottom, screen, battery, charging, COs patches, you name it.

Yeah, this phone turned out to be a huge disappointment. I faced issues with the original unit as well as the replacement unit. Eventually, I returned it and got myself a refund.
1. Back button led is dimmer than the menu button led. This is really annoying if you're used to the capacitive buttons. Even though it's a mid-range phone, this is not something that I'd expect because Rs.13,500 is still a good amount of money.
2. The phone has very obvious heating issues, especially near the top. Even when idle, temps refused to drop below 37-38 degrees. While charging, it was easily crossing the 50 degree mark. While running apps, it was crossing 60 degrees. My first unit became warm in my pocket for no reason at all.
3. The replacement unit that I received had vibration issues. The vibration kept turning off randomly. It used to turn back on after a few seconds.
4. Adaptive brightness is very slow. It takes a good 3-4 seconds for the ambient sensor to recognize the change in light intensity. I turned it off immediately.
5. Double tap to wake stops working after some time and you have to soft reboot the phone to get it to work again. However, I did not face this issue with the replacement unit.
6. The fingerprint sensor is not really as accurate and fast as the company claims it to be. The fact that you have to press the home button to wake the phone first adds to the time taken to unlock the phone. The fact that the home button isn't exactly soft does not help. More often than not, I had to keep my finger placed on the home button even after waking the device just to get it to recognize my fingerprint.
7. This one's a minor con but the ZUK printed below Lenovo on the back was slanted and not aligned perfectly below Lenovo. The print also appeared cheap and looked like it will come off pretty easily.
Considering the OPO has pretty much the same specs, I don't understand why the ZUK Z1 is plagued with so many issues. Also, in all the online reviews, the international version of the phone didn't seem to have all the above issues. Kinda makes me wonder if Lenovo has cut corners for the Indian launch of the phone, hence, the lower than the international version pricing.
Honestly, at this point, there's not much point in buying this phone. There are better and cheaper options available. Not to mention, some great phones will be coming out in the next couple of months, so it'd be better if you're willing to wait.

Mine is also showing up as a xperia z 1

very happy with this phone. after a day's work, i still have about 50% of juice. I've had xiaomi, LG, Xperia in the past. this phone just rocks.
using zuk z1

wouldnt recommend. breaking home button and missing software support and updates ... if my homebutton is broken i will swap it at amazon und buy another phone.

anybody solved the problem of failed recognition (zuk z1 = sony xperia z1). is it possible that that is the reason for google play store some apps show me that my device is not supported?

Strange screen issue

My screen has an occasional issue where a bar forms all the way across. In this bar it looks like static, mixed with glitch art. When i lock my screen it usually makes the bar vanish.
It's been about a year since it started. It was never a huge concern since I bought the device while we were still porting Android to it initially.
I assumed the gpu was just dying. Now that it's been so long, I'm thinking it may be something else.
It's happened with the past 3-4 ROMs.

Screen Problem

I've bought an Xperia Z3+ two months ago, recently, I've discovered a certain bright spot on its screen, it's particularly available in white and bright backgrounds, it's less noticeable in black backgrounds, and not at all noticeable in non-solid backgrounds.
I know that it's a hardware issue, but the warranty here is a joke, and I don't want to pay for a new screen for such a small issue.
But on the other hand, once I noticed it, it's all I could see in the mobile, and it removes the whole premium feel in it.
I've manually removed the back cover and there's no issue in the battery that would make it press towards the screen and cause such issue.
I was wondering if there's any manual fix for it? I know that it's a light diffusing layer problem, mostly caused by a certain pressure, but is there a way to make it normal again? A certain pressure in an opposite way, or heat, or suction from behind, etc.
Here's a picture that indicates the issue "It's more visible and annoying in real life"

I have the exact same problem at the very same position as you point. My country does not support officially the Z3+ and so the cost is really high. I searched enough on the internet and i think it is where the vibration is but i cannot confirm it. I also see it all the time because i simply know it is right there. At my case, there are other 2 spots but not seen so easy.
I only hope not to get bigger. I wish i knew what caused this so to be carefull (such as sun exposure or something else - although i am REALLY careful as a person with my mobile phones). I cannot help you and i got really dissapointed after my long search on the web so i will have to live with that. It is hardware problem as i really tried everything to find out that.
Hope someone has any solution. It is not only on our phone but to others too. I hope the post won't get lost after some days!

That's so weird, I thought it was caused by an anonymous fall that I wasn't aware of, the other point is barely noticeable but it's at the top left.
Also, my upper speakers started to produce mixed loud and faint sounds when i play something whike the volume is below 25%.
It's winter, and I usually text near heatrrs, which made me think that the speakers problem was caused by the heater and the screen problem was caused by a particular fall.
Since the warranty is useless I've manually disassembled the phone and there's nothing behind that spot of screen except battery, the vibrator is way below the navkeys, there's no screen on the other side of it, which actually seems to prove that our spots are similar by coincidence, because there's no pressure on the other side except for battery, and I highly doubt yours is faulty, because mine isn't.

My z3+ single sim also has the spot at the same place, but it isnt that noticable since i use auto brightness, really weird, i thought because maybe of accidental high press when the phone was in my pocket.Anyway, I'll switch to XZ premium in december, that sh*t is dope

On the top left corner i have too! So it is not a coincidence. Something is there that you couldn't see when you opened it. I only hope it doens't get worse..

I have it too not only there also in the right bottom corner and a line of 1 centimeters like 1 inch bow in the left upper corner one day was not in there and to the other plaff they appear
Sent from my E6533 using XDA-Developers Legacy app

Now that multiple people have it, I started to suspect that there's actually something.
I might open if again when I can't live with it anymore, but for now I'll try to enjoy it as it's new, and hopefully won't get worse.

I have a z3 and z4 that also have these white spots..no way to fix. look up tv lcd problems your not gonna be able to fix....it gonna keep me from buying anymore sonys till they switch to oled.

I have the same problem in the same position and it was happen after a warranty repair.... Sony didn't have noticed it....

Touch screen unresponsive at the very bottom

All of a sudden the lower part of display (about 7 mm) has become unresponsive to touch which means no more gestures (swipe up to get to home screen is not working) e struggle to use the classic navigation buttons.
Sadly I had the same issue in my mi5 but in that case phone had the issue since the unboxing.
I'm starting thinking the xiaomi touchscreen tend to be more fragile than others.
Now I'm waiting for gearbest support.
Anyone has any advice or similar experience?

Regarding Xiaomi Quality
While climbing into my truck, I dropped my Mi8 from a height of about 4 ft on accident and it landed flat on its face , on the concrete. Freaked out, I left it laying their for about a minute fearing that the screen had been smashed into a million pieces. However, I picked it up to see that it was fine, and not a single scratch. So I immediately went out and bought the Love Mei 360 case.
Anyway, regarding your touch issue, you should really provide more some information about how this issue came about, what rom were you using, did the phone get wet, etc.
Also, I had an issue with my Mi8 soon after unlocking the bootloader where the top part of the screen would not register my touches, I first tried recalibrating the screen using Miui hidden settings app, the test is called QMMI ( I think) and if I remember correctly there are several menus of testing that also calibrate the screen for me this worked and for good measure I reinstalled a Miui rom and havent had the issue since.
Try it, hopefully that is the only issue. If you are using a AOSP. It's possible that you have a driver issue. So before sending the phone off for service its worth testing.. If you are on stock and still have a locked bootloader, I would try resetting the phone before trying anything else.
Good Luck.

Some gravedigging, but the question is still on the table - have you managed to fix it?
