Xperia Play Flickering

I have an Xperia Play currently on the stock ROM, fully updated.
I noticed that sometimes when playing some games, the screen seems to flicker as if it is changing the brightness settings very rapidly.
I did a Google and could only find a few other people having the same issue.
Is this just a normal thing with auto brightness? Sucks that you can't turn it off...
Cheers

I think it's normal (or a universal bug?) because mine would do the same on stock... since changing from stock it no longer did that.

Well if you're truly fully updated (Firmware version 4.0.2.A.0.42) then you can find the setting for auto-brightness right above the slider that adjusts the brightness, which is under settings>display>brightness

I flashed the fully updating ROM and it seems to be OK now. Haven't noticed it at all since... Would be nice to know if anyone else did actually notice it though.

Autobrightness bug

Hello little birdies.
I am having an issue with my auto-brightness and I would like to know if anyone else has experienced this.
Whenever my auto-brightness shines through the power of the sun (goes to 100%) it seems to get stuck at full brightness and my already not so good screen-on time takes a dip and I always notice this too late . I use the quick settings widget which is preinstalled and the A for auto-brightness is set but when I click it the screen immediately lowers the brightness, while the A for auto-brightness remains, and a vain in my forehead pops.
Furthermore after checking badass battery monitor it shows that my screen is often at 100% sun shadowing brightness. Today it was at full mutated power the whole time. Anyone got an idea as to what could cause this? Anyone?
PS. You might have noticed in the text above that I think the screen is really bright when at full power and that I can see the screen perfectly during a warm ball-soothing sunny day.

Yes, I have a bug with auto brightness too. It seems to deactivate itself. I have activated it a couple of times and everytime it deactivate itself at 100 % after some use.
I have an international HTC One X with the latest 1.29.401.11 update.

Glad to know I'm not the only one. I will soon factory reset my phone to check if it magically gets better.

I noticed this last night. My phone was blindingly bright and I didn't understand why it was set to 100%. I set it back to Auto and so far its still on Auto. i will have to keep an eye on this.
HTC really need to fire the monkeys they have working as coders. I guess if their software is not fixed up in next couple of weeks there might be a whole lot of people, me included, who will migrate to the SIII (given of course that it doesn't have a gazillion bugs as well).

I've been trying all day to recreate the problem but ist not doing it. I put my phone in the sun, I tried using the camera app, I used the video app with its 100% brightness setting, but the phone is still showing Auto brightness.
Any ideas on what triggers 100% brightness?

I have the same problem with mine. It's just randomly turns off auto brightness

I don't know either what triggers it. It seems to deactivate at either 0 % or 100 %.
I don't have many apps installed, if I just do some web surfing and put it to sleep, when I wake it up the auto brightness is deactivated, in maybe 1 of 4 times. Irritating.

For whatever reason i haven't been getting the auto brightness bug for the past three days. Not sure how it resolved itself since I didn't get any software updates.

If you watch a video you can change the brightness and will stick and not go back to your original settings.

No, that's not the trigger. I investigated that on my phone and found no link.

I take that back. You are right! It seems the brightness setting in the movie play is the culprit. Although it doesn't always do it. One more thing for the chimps at HTC to fix.

Yesterday the auto brightness bug kicked in right before my eyes. I was browsing the web in total darkness in bed, when suddenly I was blinded by 100% brightness. So it's not just the movie player brightness that causes this issue.

Just got the autbrightness bug with the camera app. Everything seems to ****ing set it off now.. :banghead:
Sent from my HTC One X using XDA

Yeah. That's because the camera jacks up brightness for outdoor visibility. They need to have an option to disable that.

I realize that, however it doesn't always do it. Also sometimes it will kick into 100% brightness without using the camera or movie player. It seems completely random to me.

mine is stuck at zero. started this morning and I did record a video actually.
auto just takes it.to zero.
but also, if i change it directly from the srttings menu, its not.effecting at all, just staying at the same previous custom level.
whrn using widget, just turns it to zero.
opened the video player, changed brightness level and its normal now. it was in the middle, the video brightness level
ok just edited this post and its malfunctioning again.. arrrgh!

Try an application that controls autobrightness, it should fix the problem. I would recommend Lux Dash.

So it is the widget, powertoggle.
Once I fix the issue by changing video brightness, it works fone, till I toggle the widget to use auto-brightness.
Several comments on PlayStore also confirms this with several phones.
Just don't use auto brightness from powertoggle. It is actually doffetent.from what OP describes, but.people may come up to this thread while searching, so I think it willbe useful to post here.

i meet this problem

Auto brightness issue
I too had the same issue, i tried to resolve the problem with htc but unfortunately they said that it is a software but and we need to wait for an update....

Jellybean Auto Brightness

So this is the issue I'm having and I want to know if its just me or what. On stock jellybean for the Sprint Gnex. When using auto brightness and going into a bright lit room the screen brightness will raise. But when you leave the room it will not lower the screen brightness. It sticks at whatever brightness level is raised too until you lock the screen and then it resets. I have verified the light sensor is reading the lux levels and such. Is this happening on other people phones as well? And if so is there any known fixes for it.

This is happening to me as well. I am running Paranoid Android 2.0 at the moment. I was in bed, completely dark room, and turned the brightness to auto. It stayed at the full brightness setting until i locked and unlocked again.

It does for me.....but takes a few seconds

Did it work properly after that or will it still not dim when leaving a bright room until you lock and unlock.
I have tried holding my finger over the sensor for like a minute and it still wouldn't lower. I'm trying to find a reasonable fix for it. I've read adjusting the levels in the framework apk will fix it but I haven't gotten that to work yet.
Crazy part is. If you use an app to make your own custom levels it starts working. Same thing with cm10 if you use the built in options to set custom levels. But for whatever reason is doesn't want to work on stock for me.

OK. So this is wild and awesome at the same time. I flashes the newest version of rujellin last night. I left auto brightness enabled over night. Woke up today and its working. How crazy is that. As soon as I disabled and enabled it to see if it took. Stopped working again. It has to be in the phone or the code one. When I say code I mean Google code.
Sent from my Galaxy Nexus using xda premium

I haven't used stock JB, but CM10's auto brightness is great, especially all the advanced settings

It seems to be slowly starting to work. Its crazy. Makes me wonder if some info is getting left behind when I do a full restore to stock. Thanks for the info. I just want to know its not just me.
Sent from my Galaxy Nexus using Tapatalk 2
Edit. I was wrong. It wasn't working that was the screen dimming before it locked. After a some reading and searching xda it seems that this is the default behavior for the auto brightness feature on android. I'm not sure if this is correct or not but the ammount of people saying that versus saying otherwise is greater so Im going to have to agree.

Screen brightness has gone down...

Everything was fine. I had the brightness set to 60%, which was reasonably bright for me. Retrieved the phone from the table to place a call and realized the screen was looking dim. I thought perhaps I'd accidentally turned on Auto Brightness, but I realized it wasn't the case. I restarted the phone, but the problem still persisted. I did a factory reset; still the same. I reflashed the firmware, but saw no resolution to the issue. Incidentally, after the flash and the subsequent setup, I tried to increase the brightness, but the phone refused to permit it, with a message about some heating issue. I was able to do so several seconds later, however, and while there have been no more "heat" warnings, the phone's brightness hasn't been the same. I seem to have lost about 20%: what I had at 60%, I have the same level of brightness now at 80%. And the maximum brightness, on the same token, isn't the same as it was earlier. I'd appreciate any suggestions. If any of you have faced a similar problem and had a found a solution to it, do let me know.

weird ... Guarantee if still possible.

That's pretty encouraging...or is it? Nevertheless, would've appreciated some solution, but it looks like I'm going to have to make that trip to the service centre.

I saw in a review before i bought mine that if it heats up the brightness of the screen is auto. lowered in order to try to keep a resonable temperture. But nothing about your simptoms. Did you try a different kernel here on the forum or to reflash the stock kernel ?

SOLVED

I've an LG Optimus G too.
It can happen two things:
First, the phone takes down the brightness when the temperature is too high, it happen automatically.
Two: Auto brightness is enabled. Then, the phone uses front camera to see how much ambient light are everytime, then it go up and down.
You're talking about the first case, so charge the battery 100% and then unplug it and let them alone for some minutes in order to leave the temperature going down. Then go to setings, screen, and disable smart screen snd auto brightness.
Try it for some time and send us your experience! =D

There is ambient light sensor near proximity sensor,camera is not used for automatic brightness.
He can disable temperature warning with Optimus G Tweaker which can be found in Play Store.
He must be rooted firs,he can do that easily with framaroot app.

Thanks a lot, everybody. Unfortunately, I've sold my OG and moved on to the Nexus 4. I appreciate your responses, nonetheless. Have a good life ahead!

:good: Thats right, in the opposite of the front camera you can find the proximity sensor and the brightness sensor, if you have eye-recognizement enabled in block screen options, then i think it uses the front camera for both things (brightness and eye-reco.).
Near the front camera it only has notification led.
I'm root, but i dont know if someone want to desable temperature warning... it can be... destructive! LoL

How Can You Disable Screen Dimming?

Is there a way to keep the screen from dimming after a period of time? I set it to never turn the screen off while charging, but it still dims while the music app is up when it's charging in the car which is annoying. I can't find the setting anywhere in LG's settings or in tweaksbox.

I tried Lux as others have suggested but it still dims in my truck. Very annoying.

My screen doesn't dim ... did you turn off Auto brightness?
What would cause it to dim by itself? I only run at 61% brightness so maybe I haven't experienced this yet

My auto brightness is off and it still dims. Lux auto is on or off and it still dims.

Yup, I always have auto brightness off. It just dims after a minute or so of no input - which happens while I'm driving. I always keep it at 100% unless I'm in the dark which may be why you haven't noticed it - the screen may dim to around 60% anyways. I find it weird that you can't adjust how long it waits to dim, or turn that feature off. I'm guessing this is part of LG trying to help with battery life.

I've only ran into that a couple times and the screen dimmed to 90-95% and I had to manually turn it back up. This is different where it goes bright again as soon as I touch the screen and the dimming is much darker than 90% - more around the 50% ballpark.

Wow, yeah that sounds extreme...
I know it's a pain, but have you considered doing a hard reset to see if it is indeed setting/software related?

If the OP was referring to the "Screen brightness lowered due to high temperature" message.
Go into the hidden menu by typing 3845#*855# (replace 855 with your devices model number, mine is a D855).
Then scroll down to Thermal Daemon Mitigation OFF and make sure it is enabled (on).
Reboot the device and you can now force maximum brightness all the time.

I actually had to get a second phone a week ago because I cracked my screen (a few hours before my protector came in the mail). At least it was early enough that I got a brand new phone through insurance instead of refurbished, but both phones do it. Could be a Sprint vs Verizon difference - Verizon likes to go crazy with phone mods lol. Though I don't normally run into it with normal usage - only when the screen is set to stay on while charging through the developer option and I'm driving with music.

Mine does that. Sprint phone, happens after a minute of no input, including when the screen is set to stay always on. However, I notice this doesn't happen when running Maps.
I've already gone through two phones, same on both.

There are certain apps - and Maps is definitely one - which will not allow the screen to dim or the device to sleep. (YouTube is another for example, also iHeartRadio, etc.) Really the best thing to do is mod using something like Tasker or Stay Alive! as I mentioned in an earlier post for specific apps. I use mine for the Music app since typically I've got mine on the car charger and dash mount and it makes no sense to go through a whole screen unlocking routine to fully operate music after a while.
