Hi there,
I have brand new Xperia Mini - ST15i. I have same issue like many users with it and that is flickering screen. However my flickering is still slighty visible when having 100% of brightness, with lower brightness it gets worse.
I wonder whether is this bug present in all Xperia Minis or only in some models because I can still return it to supplier.
Thanks in advance.
On your position I would return it to the shop,and try to get enother device.I dont have this model but no mather you paid money for brand new phone witch should work properly.
you can fix it via hw_config file. here it is (needs Root)

Hello, im about to get xperia mini pro , but want some users/owners opinions about the phone ,manly cause my last phone was a SEw380(headaches) ,this gonna be my first smartphone and im trying to avoid headaches , so i want a good choise .So here a few questions :
1) Reading this website i found that some(?) devices have cicada(electrostatic) noises . In other website i read that the new devices have new hardware and there was an upgrade to the software's phone, so the issue was solved? this noise could harm the phone?
2)Also read about the light sensor that some times go crazy , and the screen starts flickering .
3)The keys in the bottom of the phone , right and left(i think back and the other dont know) some times go crazy (?) .
Also i really appreciate if u could share ur opinions about the phone , adv and disadv and if have other problems . Thanks.

1.) new builds dont have this problem
2.) only n bad ligntning conditions when you put finger over sensor
3.) that issue was in xperia mini, not mini pro
> technically, no. noise is from hardware (to be precise, mic in keyboard) and the noise only appear if you're recording in an empty room or silent places
in crowd / festival / party / whatever the noise won't come
> sorry, didn't happen on my XMP
> in theory, no. but in practice I find it rather amusing too since my some part of my hand accidentally hit the sensor key if I don't use keyboard mode on landscape view :v

ps: sorry for my bad english
1. The electrostatic noise is there.. At least for me, the early adopter, not sure of new hardware revision sony might introduce w/o us knowing. But its really a faint clicks, only heard in very silent video which i doubt why you would want to rec a silent empty scene :-D.
2. The flicker issue that some might encounter maybe due to the sensor getting confused whether the scene is dark or bright. So it keeps flickering. Personally i never had experience with this issue.
3. The capacitive keys are fine, unless you're holding it in landscape mode without opening the keyboard, maybe your palm accidentally touch it.
4. PROS: A very nice piece of hardware. Great performance. Benchmark even surpass galaxy s on stock fw. Overclockable to 2GHz. Small screen? Not a problem, because you type with the hardware keyboard so all of the screen estate goes toward serving you visually unlike most touch screen phone the "onscreen" keyboard fils 3 quarter of the screen. So you see less of the text you're typing.
Cons: battery life is sometime frustrating, juice defender seems to make it better but it renders my whatsapp unusable because juice defender turn off the wifi/3g connection when screen is off. Wifi range is weak compared to my ipod touch. Maybe its an issue with all android phone because i've seen galaxy s suffers the same problem.

Good evening
Im having two problems with my Sony Xperia P.
The 1st one is that when i turn on the light on the Max on my phone: the colour change..the YELLOW colour becomes greenish and every image which has a yellow colour changes into a greenish and the images becomes very ugly, and i can't use full light cuz it just becomes ugly,,once i change the light to automatic or low light , then everything returns to normal
The 2nd problem is that when i trun on my internet using the sim card ( not wireless ) the signal disappears and i have to restart my phone several times and try to call any number in order to get my phone signal back !
i'm using the stock Rom ( 2.3.7 -- 6.0.B.3.184) I haven't unlocked my phone and i just bought it a week ago !
please Help me..if this is happening with all the P devises then i'll be ok with it..if not, then i'll go back to the dealership and fix it
thanx for ur time and concern
take care
The display issue is due to that high brightness. Our device supports very high brightness so 50 % is more than enough. You can try autobrightness in power saving mode. Though I hope that it is solved in the coming ICS update.
About network issues I think you should repair once using PC companion. This firmware build has got no such issues.
For several days, my Z2 display random flickering spikes.
Is a Z2 D6503, locked bootloader, stock DRM key, rooted and Z3 firmware 23.0.1.A.5.77 for Z2.
Earlier I tried to increase the brightness of the screen, editing /system/etc/pre_hw_config.sh with these values:
"fi dev =/sys/class/leds echo 4200 > $dev/lcd-backlight/max_brithness echo 4200 > $dev/WLED:backlight/max_brithness fi " (the maximum being 4095 stock).
I did not obtained a higher brightness, but lower brightness, set automatic at maximum 255.
I tried and “echo 265 > $dev/rgb/max_brithness” , same resultat.
I put back stock pre_hw_config.sh and everything returned to normal brightness.
But, for several days, my Z2 display random flickering spikes; coincidence?
I tried repair with Sony Pc Companion, install stock 23.0.1.A.0.167 rom, but no results; display random flickering spikes.
Help little, chek Disable HW overlays under Developer options, but still random flickering spikes.
Actualy i am on D6503_23.0.1.A.0.167_Customized UK (unbranded), rooted, locked bootloader.
Everything works fine, except random flickering spikes.
Something help?
Fix?
….Or broken screen hardware?
Hv u try flashtool? I mean a clean fresh install ftf.

Yes, i flash with flash tool D6503_17.1.A.2.55_Unbranded.ftf (4.4.2), not solved.
Update with Sony Pc Companion to latest D6503_23.0.1.A.0.167, not solved.
Repair with Sony Pc Companion (reinstal D6503_23.0.1.A.0.167) not solved.
Restore DRM key, not solved.
I think the GPU is slightly disoriented, overlay problem.
By the way, in landscape mode, almost no problems; some games, applications have problems in landscape mode; in portrait mode all have problems.
In fact, I think the problem came when i updated multimedia application Album, Movies Walkman ...
I upload a video for vizual description.
https://www.youtube.com/watch?v=LZ8QPulQk18&feature=youtu.be
Can anyone tell me how completely disable the video GPU?
Thanks for help, problem solved.
Sony design problem.
The phone had little humidity inside.
Probably when we opened door to charge usb phone, or copy music phone, humid air penetrated inside.
Where Sony comes out humidity from the phone, if it is sealed?
To many people complain that they get water in your phone.
Even you can not completely seal usb connectors, microSD, and SIM, like headphones connector?
Halal waterproof phones! ... Maybe phones full of water!
My problem was solved by exposing the phone with the covers open and microSD card and SIM taken out at a heat source for 3-4 hours.
I like going and exposed to sunlight with the covers open.
I recommend that all phone owners xperia z .. to do this.
PS: I apologize because I thought the problem was from Sony updates (We are all know that the updates are not always hidden partitions of phones).
Have a nice day.
So last year i was using xperia neo v(MT11i) before it fell on the ground and turned off. When i tried to open it the phone was responsive (i could hear the sound while turning on) but the screen remained black. While charging it was still working and the led was on but still screen was black. I dissambled the phone and the lcd display was not broken at all.
I saw online that a new one costs only 10€ so i would like to know whether buying a new one would fic the problem or not. The reason is that lately i want to get started with rooting my devices but i dont want to make a firts try on my new gal s3 neo.
Thanks in advancr
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!
