Hi, i received HTC TYTN from customer. On startup lcd will display, then suddenly goes black. Phone starts completely. I upgraded rom, but still the same. On boot mode lcd allso display. Only goes black on startup. Is this a
hardware or software problem?
Thanks
Try a a HR and see what happens or try to downgrade to another rom. If problem persists it may be hardware but if it is displaying on startup it sounds more likely software. If you have other software installed you may need to eliminate problem by installing one by one until you find the problem app.
Cheers...
Hi,
I dropped my Galaxy S2 Yesterday (have no idea if this relates to it) But i plugged it into the charger this morning and everything was blue & some of the screen had turned black and some icons had burnt into the screen it looked like.
After taking it with me because it was still usable, Its not completely black except for maybe the faintest part of blue.
Im running Lite'ning rom, The newest one im pretty sure.
Just wondering if this is a virus? Or the screen is dead. I just cant see how it could suddenly die when it was flat and not turned on.
Phones not under warranty by the way. So maybe you could give me some options?
Thanks heaps guys
Probably the problem is hardware related due to the fall, but you could back all your data and try to do a factory reset to see if it fixes or not. If it doesn't fix maybe you should check your screen hardware.
Thanks for the reply,
I just reflashed Litening with Odin 1.85 and still nothing, I get the vibrations, touch lights, sound ect, But only occasionally a tiny little strip of blue along the top.
How would i check my screen hardware? Because i pulled apart my galaxy s after it died and accidently cracked the screen & Glass
How would i do a factory reset by the way? Since i cant see anything
I'd imagine it's dead. I'd take it to your local store and ask for an estimate on how much it would cost to fix it. If you can't see anything, then the screen is either broken or it got disconnected (or maybe some of the ribbons did at least).
Yeah, I just dont really wanna take the phone apart unless i know its likley to fix it.
When i first got it, I noticed it had black splotches on the screen in very dim light on a white background. Nd im guessing id have to almost buy a whole front screen assembly to replace the front screen D:.
Would i be better just to sell the phone how it is? Or repair it?
So some of you with white Z5 compact phones might have had this touch sceen bug with repetitive key presses and unstable touch screen behaviour bug which was previously "fixed" by a software upgrade:
http://www.xperiablog.net/2015/10/21/white-xperia-z5-compact-touch-screen-fix-arriving-next-week/
Lo and behold. This bug is back in MM, and there is another guy in the thread which I can see also have the bug come back
It is not always there, but sometimes its just there. I dont know what triggers it. A restart seems to help until it comes back again.
For those of you not familiar with this bug, it usually shows by repetitive touches, and highly unstable touch screen.
For example when i press the key "s", it usually put in "sssssss" like i have pushed that key 5-6 times.
Also the bugs shows, when for example you are scrolling in facebook/internet, it will not let you scroll. Whenever you touch the screen, it will enter, whereever you lay your finger on screen.
Lastly it also shows by the screen becoming completely unresponsive when you press anywhere.
I have clean installed MM and restored my apps via Sony Backup/restore app.
I am so pissed how a phone color (white) can somehow decide the behavior of the phone touch screen, and I believe sony is hiding something.
In the beginning I was thinking that maybe they made different builds for the different Z5 colors, so they might not have included the "newest" touch screen drivers for at launch time for the white version.
But the same bug appearing AGAIN in MM i have a very hard time understanding that should be the case that it was a software bug. I believe there are some hardware bug, they have somehow omitted by a software circumvention, and they forgot to add it to the white version for the MM launch.
Personally I have always had a problem with the "return" key when the phone is placed. Patch or not, this button works once out of 10.
For information, I just bought this phone. I also think there is a hardware problem. This is average for a manufacturer like Sony. I thought for a moment it back in service but when I see the number of dissatisfied with the service Sony in France, I preferred to keep my phone in the hope that a solution comes a day. We have the right to expect in my opinion ...
I did clean install via flastool also and i have/had this problem. Yesterday i did software repair via pc companion and restores apps after that and so far problem has not occured.
I also made a repair with PC Companion but nothing changed.
So there are other people here with this annoying problem.
You all have a white xperia yes?
This bug is so annoying I feel sometimes like tossing the phone into a wall.
If there was an alternative to this phone in this form factor and specs, I would have bought it yesterday.
But unfortunately there isn't
It's a poor ground connection from the digitizer most likely. You can replicate this "bug" on any device with a bad USB charger. I had a charger that would cause my Nexus 7 to detect random touches.
The software fix was likely adjusting the voltage threshold for touch events to be considered actual presses. It was likely forgotten about when they updated and just needs to get readjusted again. Too bad we don't have the ability to adjust the threshold ourselves in developer options
That being said I have a white z5c and I've only had this "bug" happen once and I just chalked it up to me being plugged into the wall and didn't think much of it. I use my phone constantly too.

Interesting theory. Do you think it is likely that this issue only occurs for one phone color (WHITE), and then only for some whites.
The assembly line for the phones should more or less be the same, no mater the color.
I also have Sony Z5 compact white version which had the touch problem from start. Now after the Marshmallow update its back. As said above, it could happen while browsing (or on home screen) e.g. Entering links instead of scolling i.e. It triggers multi click. In these situations all menu keys will also be none responsive. Its starts acting normal again after a quick push of the power button, i.e. puttning the screen to sleep.
As a former developer for mobile software, both for apps and the android platform, i thinking i would agree with the above conclusion that the problem is hardware based, and not due to a difference in the delivery software version, as i was hopping. So the question is; will this always be a problem for these versions of Z5c white, i.e. they are forgotten in new builds?
Unfortunately I'm having the same problem with my white z5 compact...

it happens that for different colors are used different materials.. probably white ones have different properties..
i can confirm that using bad cable/chargers this kind of bug happens with every device, with random touches and impossible scrolling.. if you have a well-known bad adapter and you note no differences with your white z5c, that's definitively the answer..
i think sony should recall all white z5cs and replace them with newer or different release
What revision of compact Z5 are you? Personally I have a revision 3 (that is written on the box).
I also had a touch of problem before moving to the latest version of Android (6).
My girlfriend also bought white Z5 Compact and funny thing... I put the Panzer Glass on the screen and guess what? Sometimes she can't turn off the alarm clock in the morning and sometimes navigation buttons are not responding. I tried then without the screen and it works without a problem. I am not sure if this is a problem with Panzer glass or sony's bug.
I have Z5 and have no problems, but mine is black edition
Mine is z5c white version as well. The bug started again on MM
And the bug quite annoying.
I bought it on updated lollipop.
And never had this problem before.
This plus Bluetooth is really making me hold off on not moving up from .200 lol
Argh - just saw the visual representation of this bug:
http://www.xperiablog.net/2015/10/06/xperia-z5-compact-owners-reporting-touch-screen-problems/
and it sounds A LOT like the one from the OnePlus One (driver & firmware issue)
easy blame: Synaptics - fix your ****
Anyway:
try enabling the double-tap-to-wake if it's not already enabled, lock the screen - give it some time to settle (~ 30 seconds),
wake it up (double-tap) - do some stuff - disable the double-tap-to-wake and lock the screen again.
Unlock it via power button and see if that improved the "situation".
Sony recommended a few times to boot into Safe Mode,
does this Mode exist on Android Marshmallow ?
Does it make any change ?
Had this in Nougat is there a fix?
It feels like a software problem! You can try to reinstall the system!
First consider whether it is a system problem. You can refresh the system to see if it is back to normal. If it still does not, then you may need to update a new LCD screen. You can go online to find the repaired video as a reference. The witrigs repair video is doing great, you can check it out!
(UPDATE: Here is a link to a short video of my issue: https://youtu.be/YqKW3tU4Fhw)
So I cant seem to find ANY info relating to this issue aside from results for the LG G4, but the solutions for said phone are all over the place. Some are bad screen, some are related to sim tray, some are related to water damage and battery etc. So basically, about a month after buying this phone (KIW-L24 US version), the screen started to artifact and flash in and out randomly. There is nothing that seems to trigger it. I have set the phone down on a table while on the homescreen and watched the lightshow. It is basically a mixture of the problems seen in these videos (Feat. LG G4).
https://youtu.be/gAUkXLR7eQI And https://youtu.be/QstOH66pfiU.
Symptoms:
Screen will randomly start to flicker and fade in and out. I will also get crazy artifacting lines. (Think de-gaussing an old CRT monitor or simillar to what is seen in the second video)
If i see the problems happening, locking the phone and unlocking again will sometimes fix it temporarily. Other times the problem continues after i turn the screen back on.
Sometimes the screen will refuse to come back on. The backlight turns on, and the digitizer responds, but the screen is still black. Making sure the screen really is off, I can come back to the phone a few minutes later and it will turn on. Other times ill have to hard reset the phone (hold power button 10 sec) and it usually brings the screen back to life.
Background:
I bought the phone "used - Like New" from amazon. It came with all the original accessories and even still had the film protector on the back of the phone. I may have noticed these problems after I received the phone, but they really only started to show about a month after purchase.
At first I though it could be software related as I was running CM13 and something could have been corrupted, so i did not just a factory restore, but a full reflash. This didn't solve the issue. Restarting my phone and the reflash did help, but the problem returned. The inability to turn the screen on persists through a reset and I have to wait till the phone boots again to get the screen back. Sometimes takes more than one reboot. This pretty much confirms a hardware issue right? If i put the phone on a black screen, i can see three small fuzzy "dots" in a triangle shape in the top left quadrant. Could the screen have been damaged by whoever owned it before returning it? They are not dead pixels per se, but seems more like areas where the backlight is showing through ever so slightly more. Not visible unless you are on a black screen in a dark room. Ill upload a video showing some of the issues. Any help is appreciated!
im afraid you need a new display brodar...
Seems to be hardware issue. You can visit the nearest service center to get it fixed for few bucks if you don't have warranty.
Yeah that's what i figured, i just needed conformation. I was able to get amazon to take the return even though I was out of the return period. So at least ill be able to get a refund. Ill just pay the extra for a new one this time haha.
One question : Do u have over heat problem with ur phone ?? If u feel ur phone is more than work from the back dont replace . U'll damage the new screen also . Some ppl erported over heat cpu issue with honor ! ;.

Try moving to stock once , if it fixed stick to it for few days . 99% of possible cases for hardware issue .

A small yellowish colourn in my phone too. Which is in upper right cornor.
It's due to heat. The adhesive between display and touch changes somehow due to heating in that area; I had this kind of issue with some of my previous phones. It didn't affect touch or display colors, and in time, weeks to months, it cured by itself in some cases.
