z5 brightness decrease - Xperia Z5 Q&A, Help & Troubleshooting

so i just bought a black Z5 dual and there is something about it thats bothering me
sometimes..not always when i turn the screen on,after 8 to 10 seconds later display brightness drops like 5 to 10 % and comes back to 100 right away.
the drop and coming back takes less than a second,but it is noticeable
and yes the adaptive brightness is turned off,even turned of the smart backlight control
interesting thing is ..i even noticed this happening even on the lowest brightness and it drops even lower than that!
i saw this and decided to go the shop i bought it (i live in iran) and give the phone back and take another phone instead
but the seller himself he had Z5 too after,i showed him this issue,he started to work with his phone and then...the same thing happend to him too!
this thing doesnt happen always and it does happen even the phone is cooled at like 27 c so it cant be cpu throtle
the phone is running at .185 MM At the moment and im going to do clean install of .253 in a few minutes
so please guys give me solution or give me reason to bring the phone there again and show them this and tell the seller that there is something wrong with my z5 and his z5 ,and make them change the phone for me
i have only 2 days left so please guys.

[Q] No Display

Anyway I haven't been using the fuze for like a year now so if you guys can't fix it then no problem. So, the display does not show at all. When I turn it on you feel the vibration, however the screen does not light up at all, you get no display. How it happened was that I had slept on it by accident (which makes me think it be fix unless I do something physically like take it apart), when I woke up a realized that I was laying on it I immediately got up and the display was not showing.
I've tried leaving it plugged in for 8 hours and it didn't work......that's all I tried.
Thanks for all the answers.
I sleep on mine all the time...
Have you attempted to get into bootloader; to see the multi-color screen?
no display
i think its about time you opened the device up and seen whats going on inside
if you break it, no biggie = can't fix it then no problem

[Q] touch response gone - but works when i freeze the phone to 24degC

I have a strange issue on my nexus 5. Little long post - so please read at leisure.
Got my nexus 5 in November, the october batch. No issues till now and on 4.4.2.
Little background:
I am in Bangalore, India, where the noon temp probably hits 38C (100F) in May month.
I went on bike in tuesday at noon for couple of hours with nexus 5 in my pocket. That might have heated up the screen and insides.
I have antutu widget that shows the temperature, memory and also the cleanmaster.
I came back home, didnt touch the phone for a while. Later on went out in my car by 4PM. I observed that the touch response is gone. The screen is working and displayed time accurately, the notifications are coming, even getting calls. However, i cannot take the call since i cannot slide to answer.
By evening, i went to my office and observed it worked for a bit and then stops working all of sudden.
The temp shows 32C (for the processor i think) and it jams the screen.
I went into a cold conference room and stayed there for a bit where it was 23C room. The indicator showed 28C and touch works.
If the temp shows 30 it jams again.
I went to the local LG service center(Marathalli, Bangalore, India) last night and showed it to them. It seems they don't have stock of the screen to replace and asked me to call back. Today i checked its not yet come. Tomorrow might be possibility they would get and replace the touch screen.
However, if I continue with this technique of freezing the phone to cold temp and observe it works, slides, opens all tools. Once it is little heated up, it jams.
Now i observe white horizontal patches coming across the screen . If i turn off the screen and turn it on, its gone but comes back again.
Very strange indeed for me. Any insight on what is happening? I expect the LG nexus to be tested for high outdoor temperatures like in tropical India (40C - 110F).
It might have broken something internally like a small circuit being burnt and its probably working only in low temperatures. Still it is appalling.
Any thoughts and ideas?

We can assume that the digitizer is losing connection as a wire expands and contracts. LG should replace the screen for you free of charge, unless they come to the conclusion that it was damaged by the user.

[Q] Screen goes partially blank

Hey, so I have this weird problem with my G Flex 2.
I got it around 40 days ago from U.S. Cellular.
I have run into this problem about three times now, and from what I can remember it always happens when I have music playing. I tap the screen on to the lock screen then let it go to sleep or turn it off myself. When I wake it back up the screen is all black except for a few millimeters on the top, where I can see some display.(*note, this doesn't happen every time)
I am able to scroll through the display but no pop up menus. Since the battery is sealed off in the back of the phone I can't use that fix, holding the power button only brings up the menu option to turn off the screen which doesn't do me much good since I can't use the screen.
If I wait for 5 minutes or so the phone will right itself, but I don't want this to be a persisting problem. I'm not sure if this problem is tied to the music playing, it hasn't happened when it isn't playing, but I play music on my phone quite often. (note* I am playing the music from my phone, not streaming)
If you need more info I'll do my best to provide it. This is all I can think of right now.
Honestly, I don't expect anyone to have a fix yet since the phone is fairly recent and not as popular. I tried looking under G3 forums since the UI is pretty much identical, but I didn't find anything.
Sorry, my post is a little wordy.
I'd appreciate any help anyone can provide. Thanks
Yes, this has happened to me twice recently too. Once the screen was completely black except for a bright white line at the very bottom, but the phone was still responsive behind the dead screen. The other time there was a distorted/ghosty notification bar showing at the top but nothing else (like what you reported). Then the problem would resolve completely and spontaneously after resuming from sleep a few times. I have the Korean model (F510S) which was a gift so I'm stuck with it - no returns or warranty available.
bonebeatz1234 also posted about a similar problem. Seems like a hardware fault?
The replacement phone screen was fine i had a different issue of over heating and had to return it . I opted to get another device the note 4. Didn't wanna go that route bit had no choice i loved the design and ui of the flex 2. I wished lg would of just ditched the 810
~~~
Hi, I encountered same problem here.
Is anyone able to send me a screen shot or a video of this problem.
As I need to use this to prove the situation and claim warranty from the seller, however I didn't take a photo or something when the problem happened to me.
please sent to [email protected] if you have the photo or video and many thanks~
Just had this problem also had a g flex 2 for about 21 days now and it happened to me after a restart in the car with a pinkish line at the top and the phone was completely responsive even though the screen was blank
I think it might have to do with heat cause I held it by the ac vent while I was reading this board on my nexus and when I looked back at the phone it was working perfectly
But I swear during my time with the phone it heated up way more than this time and this time the phone wasn't even hot
I reset the phone like 3 times before I held it to the vent and it didn't help at all
Using the att variant with android 5.1.1
Have the same problem every now and then, found a recommendation on another website and in the instruction manual to reset the phone by holding down the power button and volume down button for about 10 seconds or to turn it off by holding down the same buttons for 20 seconds. I find what works better though is to just leave the phone alone and it corrects itself within about 5 minutes.
Having this same problem. Happens once every couple of weeks. Any updates on this?
I think that this is a heat problem....everytime i left my phone in the sun, it show me this strange error.
I'm not convinced its a heat issue. I looked at my battery chart the last time it happened and it was barely over 90 deg. It seems it happens to me when it is charging PLUS doing something like streaming music or GPS is on. I need to start taking notes. I should have done that before.
this have happened to twice too. weird anomaly.

Having the same random issue. Today it happened and reboot would not fix (it usually does) finally after about 30 minutes the screen came back to normal. I now disabled lock screen in case I need to get data off the phone from pc ? in the case that the issue becomes permanent.

although it's an old post, but worth to mention, that It can happen to all the LG Flex 2 models.
It is caused by a heat or inaccurate voltage. let me explain how it can happen:
heat - when you put the phone on the car's cradle under the car's front windows during a sunny day - it will happen.
voltage/heat - when you charge your phone and not using your original charger (eg chinese car chargers) - it will happen.
so what to do? I've noticed that putting the device over the cat's air conditioning , can reduce this to few minutes. also, if you can, mount your cradle over one of the air condition outlets and it will freeze your phone all the time

Z3 Overheating

Hi,
I think I'm having an issue with my new Z3, it seems to overheat very easily. We have high temperatures here in Czech Republic currently, however this happens indoors also (not more than 26 °C).
Phone often gets over 60°C even if its not under heavy stress, i.e. just chatting over messenger and browsing web. When I try to start camera, it shuts itself off, beacuse the phone is too warm. I even got like 68°C when trying to take a picture!
Is this normal or should I have the phone replaced?
Thanks
I would say not normal, our temperatures in Toronto Canada range between 30/40 in summer and I've never had a over heating issue.
Have you tried factory reset?
Currently i'm in holiday and i'm always near the beach, under the sun my Z3 gets near 60-65 but when is like 8 pm and there's no sun anymore my phone is near 35
Same here.
~~~~
Jo, tady to samy, hruza. Zkus 4K video - ja muzu natacet asi tak... 20 vterin? Kdyz mam stesti. A neni moc horko....
Same here. Temperature gets to 60+ degrees while on 3G plus facebook/whatsapp. I will try resetting to stock and check if it fixes the problem.
I used to have this after upgrading to Lollipop.
Factory reset and wipe fixed all problems; overheating, battery issues, etc.
Over heating is always a problem for xperia Zx especially if you live in high temp country like mine
i have and use the original z, z1, z2, and now z3 and it all the same
even on standby the xperia will get hot if im outside under the sun
and using the camera will make it worse, the device will show over heating need to shutdown
using iphone 6 plus in the same condition is better but after dozen pic taken, it show the same error
the only cure for me is to power off the phone until the device no longer feel hot in your hand
but for now i usually use two phone if im planning to take many photo, one usually powered off and use the other one for camera, if its started to get hot then turn off phone and powered on the other phone lol
btw i heard z3+ and z4 overheat is worse so not planning to upgrade to z4, gonna wait until sony wake up and do major update to their line up
this just happened a few hours ago.
I've visited my grandma today in some places in Metro Jakarta Area, and boy Jakarta is as hot as the hell of the hell, when i go there, to her house, it actually looks green and cold, despite that afternoon it's sunny. but boy when i got out, it just burns my brain, head, and body inside and out.
So I kind of played some music in my car, but i turned off the music, and i got out of the car and go to the house, when i came in, wow, just wow, it's like i've just came in to hell, you know. Well in that time, i didn't feel that hot inside me, but my phone didn't feel the same as me...
you know, when i got out, i had my phone on aeroplane mode, and i don't do anything with my phone, after i came in, i just did light things with my z3, and after that, i played some games, and the phone started to became warm, well not that warm, but just a tad warm. and when i finished playing the game, i closed the game, and then lock my phone, and my phone seemed like it didn't like the environment and the air quality inside the house, so it became really really warm after that, i checked the temperature at cpuz and i saw the battery temperature, that is at 36 or so celsius, and i saw the thermal, most of them are like 40-50, and it is raising. and it just slowly getting hot until it is super super hot, i got panicked that i don't check the temperature and just turn off my phone to let it cool down.
Well my phone is new, and here, people are just ambitious when some person got a new phone, especially when it is a good one, like s6,z3+,iphone 6, or something else, especially z3 like mine, because sony users here are a lot but i rarely seen the users. so when i turn my phone off, my uncle was looking at my phone and started to tell me that he want to borrow it for a minute, so i gave it to him, i forgot to tell him that i turned off the phone because it experienced overheating that time, so i think he turned on the phone, i saw that fancy startup screen with that purple flow thingy, so i told him late, and asked some questions about the phone, and then i took the phone. I got panicked again because it's getting even hotter.
well that room is super super hot you know, but i'm one of the people who hate hot or warm environments, but i don't feel that hot, although it is warm, but some people thought that, that room is as hot as hell. so when i checked the phone, i saw that the startup screen is still running, it's unusual because it should display the lockscreen that time, so soon after that, the phone got lagged startup, and a few seconds later it got freezed, and then, like 5-8 seconds after that, the screen is pitch black, i thought the phone died, but it was restarting again, so i wait a couple of seconds, and it just did the same thing as before, so i'm worried, after like 5 times of doing the same thing, i asked my sister if i need a pin for force reset the phone with the button inside the microsd/sim slot. And then the screen turned off with 3 times vibrate, that was my first overheating and my first time of reseting a phone like that on my z3,
Oh yes i just remember, the phone is at 13% that time before the first turn off. And continuing on, when it already cooled down, i pressed the power button to turn on the phone, and again, that thing happened again, and it overheats again, i got really worried, so i let it cool down again, and then i tried to turn it on again, but did the same thing, so i turned off the phone again with the same method, and take my charger inside my car, and charge my phone, after that, it charges at 9% mark, i let it charge for some minutes and then, i turn on the phone again and just pray , then finally, the phone turned on without an issue, when i tested everything inside and outside it, everything seems normal.
that is creepy you all know? hahaha
btw, i'm not really in jakarta, i'm in sawangan, depok, it's like jakarta's sub city/ inside Jakarta metro area. but both are as hot as hell.
edit : oh yes, it's not just me, my mom's gnote 8, my sister's iphone 5s, and even my blackberry curve 8520 did the same. but my z3 is like, far severe one
but other than that, my phone didn't feel and seem as bad as you are, i just got like warm but not that much heat on mine when trying the same thing with the same condition as you are.

Broken screen working again on low battery

Hi guys,
Some while ago my oneplus 7pro felt from the stairs. The backside is complety broken, but the frontscreen was ok because of the screenprotector.
After a while i noticed 'a lot' of dead pixels on the lower left side of the screen. The phone was still usable so i didn't bother about it.
Suddenly during normal use, my screen started flickering and my screen went off. It seemed that the screen was devided in 2 where the notificationbar was on the same height of the broken screen pixels.
I could see some things, but with a green film. But not possible of unlocking the screen.
I tought that the screen was completly broken and i moved to a spare phone.
I still hoped that the screen would do some sort of a reset when I let the battery completely drain, charge a bit and try again.
I checked almost every day on what percentage. But when it was on 13% (or nearby that %) the screen was working again like nothing happened before. I tought it was working again and charged it.
Because it worked again on a low percentage, I tought it may be a lower refreshrate of some sort of stuff that is on during battery save mode.
I left it charging some small time, tried again and screen was broken again.
I tought it was a lucky shot, so i didn't bothered again about the phone.
Yesterday i checked my phone again out of curiosity, and guess what, it was working again.
So I'd like to know what might cause it to work again on low battery. I lowered the resolution and refresh rate already.
Anyone who got an idea?
Nothing short of taking the phone to a repair shop will restore your phone to normal.
It's just going to get worse, there's nothing you can do to stop the progression, short of a repair & even then, you're probably throwing good money after bad, considering the type of damage incurred.

Can't be sure, my guess is some voltage leakage on higher voltage and short the screen somehow. If you can try de assemble and re assemble the phone. Just my guesses.
I suppose the higher the voltage the phone is able to provide the screen the worse it's going to get. Send it to OnePlus. Don't get it done independently, they cost way more
