I think I finally fixed screen flickering! - Nexus 7 General

I usually use my n7 in my room which is at least 4 walls away from the router and at night time the screen flickers like crazy to the point of being unusable. I tried setting up a new router one room away and flashed the latest AOKP build 3 and went to settings and selected the two options to reduce flickering and I've been using it for two days no in the same exact conditions and it has yet to flicker!
Just wanted to share

Want to buy the SP but ...

My contract is due for renewal and so far I have narrowed it down to the xperia SP , HTC One mini and S4 mini. I was almost about to order the SP but found that some people are having problems with the touchscreen not responding, and wifi quality.
Is the touchscreen issue resolved or is it a lottery if you get a good phone or bad? The sp has all the features I want but its reliability seems questionable.
I hope someone can help.
I have not encounterd the touchscreen issue but i do have wifi problems. Ibelieve that these are software issues and Sony is planning to roll out 4.3 in december...

latest firmware has fixed wifi prob IMO
Wifi quality is just horrible. Im on the newest firmware, but sony didnt fix anything.
I think, theyre not able to fix that, maybe because it could be a hardware issue.
I hope not, but we will see, when Android 4.3 comes out.
I also tried different fixes for rooted sp's, but nothin worked for me.
Im just 3 meters away from the router, but the signal is damn low.
I've had my Xperia SP for about 9 days (bought it on 2013-10-05). My experience:
Touch:
No problem at all with touch. Smooth as butter. Tested *without* a screen protector.
Wi-Fi
Wi-Fi is a mixed thing...
On my dining room, it's weaker than my previous phone.
But in the bedroom, it's stronger than my previous phone.
I found that laying the phone flat on the dining table resulted in severely weakened signal; propping the phone up with, say, a cigarette pack, improves the signal considerably. This leads me to believe that the 'problem' is with the Wi-Fi antennae orientation. In the bedroom, the signal quality is great because the phone's upright relative to the ground (and therefore is roughly parallel with the Wi-Fi Router's antennae).
I haven't had a problem since I turned off 'keep wifi on during sleep' and 'location based wifi'. My issues were with authenitication, never range (which has always been excellent).
I'm think stamina mode conflicts with keep wifi on during sleep. Also, I've got an old router at home, maybe modern routers cope better with suspended wifi connections?

U are wrong. I tried the wifi range with 2 different routers. 1 at my Home, a modern one and one at my parents house, an old one.
Results were the same.
I also disabled stamina mode, but it didnt increase the wifi range/quality.

Just my experiences - most people have complained about range, but it has never been a problem for me, the range is as good, if not better than my other WiFi devices. However sometimes my phone would not connect citing 'authentication problems' many times in a row.
Princeton University is of the opinion that many android builds before 4.2 have a flaw related to 'keep wifi on during sleep' - in essence the phone holds on to the IP address leased to it for too long.
Even though I had partially resolved the connection issues with the well known tweak of the wifi parameters I still had the occasional authentication error and it sometimes took ages to get past the requesting IP address stage of connecting to a router. I haven't had these issues since turning off 'keep wifi on during sleep'. Purely anecdotal evidence and if your issue is range related not applicable.
I decided to get this phone after getting an offer I could not refuse from Tmobile retentions. I will receive the phone tomorrow and will report back once I've tested it out.
An Update:
Phone is very nice looking and fits well in the hand. Slightly smaller than Galaxy S3/S4. It's about the same width as an iphone 4S but longer. A perfect balance between the big 5" phones and the smaller 4" mini versions.
So far the touchscreen worries I had haven't materilised. I think they must have sorted that problem a while back. The wi-fi works fine but signal quality looks weak. The signal shows 2 bars(out of 3) even in the same room as the router and about 1 bar in another room furthest away.
The battery life is pretty amazing for me coming from an Xperia play. I charged it via USB connected to a pc for 7 hours so it had a full charge at 4.00pm Thursday last week. I have not connected it to a charger since then and right now (Monday, 12.47pm) it is showing 36% remaining. Thats nearly 4 days without charging and its still got probably another day to go.
At one point I checked the level before going to sleep and it was showing 92% and when I woke about 6 hours later it was still showing 92%..I reset the phone because I thought the battery meter had crashed..lol. (Note: stamina mode was ON to get this result)
I only used it for 3-5 calls per day and about 20 mins of browsing over the 4 days. Not a lot of usage but that's normal for me so am really happy.
Overall an excellent phone with a superb light bar
not great
iam using xperia sp since last month. the touch screen works great, but i want to mention that sometimes its not working smooth. i have to touch double time or have to touch some hardly. another important issue in my sp is its get overheating while playing games.
normally its not heating while browsing orusing any other application .its get heating only when playing games like deer hunter, temple run, etc. other thinks or ok.
so decide yourself.
I'm planning to buy this too, just wanted to ask, does flashing a custom Rom fix the touchscreen/WiFi issues if there are any?
for wifi issue, there's a fix posted in this forum, involving replacing the wifi config file with the config file of Xperia L, but it needs root access.
however i didn't have this issue, visually the wifi bar displays weak connection, but i don't experience dropped connections any worse than other phones.

it's supposed to heat up whilst playing games, every phone you can get does, cause it uses the GPU more and the CPU stays at higher frequencies more often. That is normal
I checked temps on mine and it doesn't get any higher than about 45 degrees C.
I recommend you root your phone and swithch to Interactive kernel
regards
my sp is good enough...
i use sp for 1 month,never crash with bugs u tell,i think sp is a nice choice for u

Screen much brighter on one side

So. Recently got my second transformer. After a few hours use it switched off and refused to turn on at full brightness - in the dark i could just just see icons on the homescreen. After a while it seemed to tun on again. Crazy. So i updated to and used latest 4.4.2 stock for a day, the screen was working perfectly at all brightness levels, uniform, no light bleed. Then i flashed a few of the available CM based roms. This morning, a few days in, i notice that the backlight is much much stronger on the right.
At low brightness it was completely ridiculous. Its like one of the rows of leds wasnt on at all. So i reflashed a backup i had from install day and now everything is just fine - uniform brightness, working perfectly. It seems to be a driver bug. But how did it survive me going from kernel to kernel?
So now im wondering if its a hardware issue... any thoughts?
Ive now noticed this happening on a number of occasions to different rows of the backlight - sometimes at bootom, sometimes at bottom and right. Anyone else seeing something like this?
Sounds like hardware to me...

I flashed the latest cm and this seems to have stopped happening so looks like driver issues. However, the screen continues turn off sometimes, and when it does it needs two presses of the power button to turn back on. Its a crazy thing asus - i had the last infinity too, sold it after a few months because it just wasnt as good as my nexus 10. And now this... pretty amusing.
Dunno why i keep buying asus. Must be my good experience with their motherboards or something... usually they also have excellent support and firmware updates.

Screen flicker poll G Watch R.

Hi,
I've started this poll for ALL owners of the LG G Watch R.
The question is: does your G Watch R flicker after charging it to full 100% when you take it off the charger?
After selecting yes or no on this poll, can you check your build number on your watch and post it here?
If you post the info, please also note if your watch does flicker or not to keep the results clean.
something like this:
Does flicker:
Software version: 5.0.1
Build number: LWX48P
Serial starting with: 412KPGS0139XXX
or
Does not flicker:
Software version: 5.0.1
Build number: LWX48P
Serial starting with: 412KPGS0139XXX
What I'm trying to figure out by starting this poll, is if it's hardware related or not.
To check your build:
Go to "Settings" on your watch.
Then press "About".
in the about section you will find the following info:
Software version: 5.0.1 (This will change after a new update.)
Build number: LWX48P
Serial starting with: 412KPGS0139XXX (Just replace last 3 digits with XXX, we don't need to know your exact serial number.)
Above info is from my own LG G Watch R.
Thanks for participating
Treborov.
Results so far:
All watches posted so far have Build number: LWX48P. I wonder if there are other build numbers out there? If anyone has a different build number please post it here
Serial ranges: 410KP series, 411KP series and 412KP series.
Everyone so far is running software version 5.0.1 (Which is the latest update.)
Remarks by users about what might cause the flickering effect:
Screen brightness settings: 1x
(Google calendar event) notifications: 1x (Could be any notification because I had the same problem with multiple notifications that all tried to pup up at once)
Watchmaker app: 2x (installed on 2 watches that have the flickering effect.)
Hardware related:
Loose display ribbons: 1x
I have had the snow-crash in one and the flickering in my second watch, now on my third. that one seems all right at the moment. what makes me suspect hardware in stead of software is that the LG G, does not show this problem. and both are technically quite close related.
If my watch shows the flickering again, i will partake in your experiment, as i am quite curious as to what is causing this. I also noticed the much brighter flickering as brightness was down to 1.
As i read the posts concerning this problem, i also noticed that the part that flickers is not always the same, on my watch it was the lower half blinking, others have mentioned the upper half.
It still reminds me of what a led does when power goes below a certain threshold.
Good luck in your project!

Thanks for leaving a comment, I did read all your comments in the other post about you sending your watch back to LG.
So you're on your third LG G Watch R now right? Not exchanged it for an LG G Watch?
If you got another Watch R. would you mind posting the build number?
Let's just hope your 3rd watch doesn't go all "disco" on you like the other two
Disco time haha. Half of the screen flickers, same as the OP explained. Really annoying, happened 2x already within 3 weeks of owning the watch

I had a Pebble before i had an LG G, my wife now has that one, i decided to stay with the LG G R, because the recessed screen helps in preventing random contact with my sleeve (thus interrupting the music playing on my headset), and i like its looks a lot more then the LG G, the screen above the bezel like the 360 has, is why i did not got that one (besides the poor hardware and battery) until someone writes an app that kills the touchscreen until the crown is pushed once or say 2 times, all other options are just to annoying
Hmmm.. 2 days straight of flickering every morning when I tried to check the watch right after I wake up.
I noticed that after I restart the device, a Google calendar event notification will pop up. Then the flickering will stop
Looks like a Calendar Event notification bug in Android wear, could someone confirm this?
Update : It flickers again, no calendar event notification. Maybe this is a hardware problem

O.K. Update on my watch.
I did a factory reset yesterday on my LG G Watch R.
I haven't touched the watch as in, changing face plate installing software etc.
This morning when I took it off the charger it didn't start flickering like it did the last two days. (So it was working as it should.)
Things I had installed on my watch when it was flickering: (before factory reset)
Multi Calculator
Instaweather app.
Intellicom Watch faces app.
Luxury watch faces app.
WatchMaker free app.
Facer app.
After factory reset, the only thing that automatically popped up on my watch when I checked watch faces, was the Facer app. The rest of the apps wern't showing on my watch anymore.
However, I didn't uninstall those on my phone.
I uninstalled the Facer app on my phone.
After checking the Watch Face options this morning, all the installed programs are back on my watch.
It seems they all got synced again between my phone and my watch.
Maybe I checked to soon yesterday after the reset and these programs weren't synced yet.
I'll take a closer look after next factory reset.
Thanks everyone who has participated so far in this thread :good:
@unclebor
In your app list, we only have 1 common app installed.
I also installed watchmaker, and as far as I remember the flickering started after i installed that! I will uninstall watchmaker and delete the data folder because I already tried uninstalling it but the data folder was not deleted.
Hopefully this is the culprit, if not maybe this is a hardware issue.

The flicker is most likely due to a loose display ribbon connector and stops after a while because the watch warms up, the connector expands and makes better contact, but it will remain intermittent since it's not pressed all the way in. You need to open the watch and press in all the connectors (there are 4) and the flicker will likely stop.
For the record, I'm on 5.0.1, LWX48P, 411KPSL0096XXX, no flicker.
Mine does the same with LWX48P. It happends since i started using it with always On screen. Can we return it and exchange to a new one? I like pebbles warranty since they have issues about flickering screens too. Returned and sent me a new one.
Since update 5.0.1 the display flickers sometimes after fully charged. Power off and power on the watch helps for me (no reboot!)
Software version: 5.0.1
Build number: LWX48P
Serial starting with: 410KPNY0036XXX

Update on my watch day 2 after factory reset.
I took it off the charging cradle this morning and again, no flickering.
It seems the factory reset helped so far. (Crosses fingers.)
my current settings are:
Adjust Brightness = 4 (stock after reset)
Always-on screen = off
Face plate = suit
Installed apps:
Intellicom watchfaces (did not select any face plates after reset)
Luxery watchfaces (did not select any face plates after reset)
Watchmaker (did not select any face plates after reset)
InstaWeather (did not use this after reset)
I'm going to change one setting today, and that's the Adjust Brightness = 4 to Adjust Brightness = 1 and see what it will do tomorrow when I take if off the charger.
If indeed it flickers again tomorrow (which I surely hope it won't), I'll change the setting back to 4 and recharge it to 100% and check again.
After tomorrow (if the brightness setting isn't the issue), I'll put the brightness level back to 4 and select a 3rd party watch face.
Yes, this is going to be a slow testing process, because I want to check only after a whole night of charging to not manipulate the charging time.
When I can trigger the flickering process by changing some setting, I'll just recharge it on the fly. Check if I can make it "un-flicker" by undoing the last change I made on the watch.
if that doesn't help, uninstall the program that made it flicker in the first place and check after that. (if it's a 3rd party app and not a Google Wear 5.0.1 setting)
If that doesn't help, factory reset, one more night charging on default settings, if that doesn't make the watch flicker, re-install the program that caused it to flicker and retest the last procedure that triggered the "disco" effect.
Makes sense? LOL for me it does
I wish I had like 10 of these watches, would make the testing process go much faster.
Thanks again for everyone participating in this poll and posting serials and such :good:
It flickers again this morning without the watchmaker app. So that's not the culprit, really annoying, i will return this for warranty.

Why don't you guys return the watch? Sod the testing the watch was not designed to flicker! When I get mine on Xmas day, if it flickers.. Back it goes

There's a reply on the other thread, he returned it ang LG fixed it. But flickering still persist. So looks like LG doesn't really know how to fix this. But I sent mine for warranty.

Here are my 2 cents about the flickering on the watch:
Quick summary,
Got the watch (day 1), it was fully charged 100% when I turned it on, paired it and played with the stock settings and options.
Didn't flicker the first morning after full charge (day 2).
I played with it a lot, installed apps, changed face plates, (Also tried out some MOMO 360 face plates through the 3rd party app to see what they looked like on this G Watch R, didn't like them, chose another one), played with the weather app..etc.
Flickered after full charge! (day 3).
Played with it a bit, didn't really pay attention to the flickering because it was working normally after a reboot, just thought it was annoying. However put it in the back of my head for the next morning to check.
Flickered after full charge! (day 4).
Thought it was pretty annoying and checked the web for possible solutions and if other people had the same problem with this "disco effect".
After reading the threads here, I decided to do some testing myself.
I did reset my watch to factory settings.
Didn't flicker after full charge (day 5).
Didn't flicker after full charge (day 6).
Changed display settings to brightness level 1 (was on 4).
If the watch was broken, hardware related, the flickering effect would be there all the time right? (Broken = broken, no matter what the settings).
If it was a loose wire, it wouldn't only flicker after charging. (Unless the watch heats up to a certain level on the charger which would cause a bad connection in the watch itself which makes it flicker only after recharge.)
Therefore I think it's either software related OR the combination between the brightness/always-on settings and hardware.
There might be something in one of the installed (3rd party?) apps OR in the brightness/Always-on settings that triggers the "disco" on your watch.
Maybe if the brightness level is put below stock settings, there is a condenser that regulates the screen brightness? (Going to put this to the test.)
IF tomorrow morning my watch flickers, I know it's the hardware that can't cope with the low brightness setting. If not, I'm going to change the brightness back up to 4 and install a 3rd party watch face.
I still think, because Dersie changed his brightness settings through another app, it is software related.
if it was hardware related, it would always flicker after recharge, no matter which app you use to dim the screen. (condenser/hardware goes all stressed when it has to power up the screen in dimmed mode).
It's like searching for a needle in the haystack, but hey.... I like finding needles in haystacks.
It gotten worse! After charging I decided to turn it off, I slept, when I woke up I turned it on, then seconds later flickering happends. Restarted it, but still the same. I turned it off for a couple of times. Until I decided to just leave it on until flickering dissapears. Did factory reset but still the same. Sick and tired of this, $300 watch and its defective I dont wanna deal with this everyday, Im gonna return it to newegg since they have 30 day return/replacement warranty. But my watch has a lil dent on the bezel already. I hope they still accept it.

Mine started flicking after 4 weeks, batt at 42% 2 day after charged, on a table since 1H, so no movement to move hardware screen connector, no after full charge. No issue the last 2 days after using brigntness setup with SWApp....
condenser problem is maybe a way for the problem. It happen only from screen OFF to ON for me, never when screen is already ON for awhile. So only after condenser can be not charged.
Time to let you guys know about what's going on with my watch.
Didn't have much time to post anything the last couple of days :/
All I can say is, so far so good.
The last 3 days it didn't flicker at all.
I am running a 3rd party watch face now, brightness settings set to 1. No flickering after full recharge.
I don't know what caused it in the first place.
Maybe it was a MOTO 360 face watch I tried on my watch to see what it looked like, I don't know.
I will do some more testing after these busy days at the end of the year.
I will post again in this thread when the flickering returns or when I find out how to trigger it.
If I can find out anything else about the "disco effect" on the G Watch R series on other sites, I'll post a link here.
I'm sure this isn't over yet, I guess I am just lucky at the moment that it doesn't flicker.
However, knowing hardware /software it will probably come back since I already experienced the affect on this watch.

S5 mini spikes on screen

Hi,
Ever since I got my G800Y a couple of days ago, I have been unlocking my phone to see these blue spikes on the side of the screen. This doesn't happen all the time but it happens ~ once every 10 unlocks. I have flashed cyanogen mod onto it, although it still showed up out of the box. I spent so little time with it stock that I only saw it twice and thought it was an anomaly.
I have my phones about and a photo of the artifact here: imgur(dot)com/a/GwzWL (sorry for the whole dot thing, but I can't post links)
It seems to happen most frequently when the battery is 100% (I have re calibrated my battery) and during night time.
It doesn't show up in screenshots
It seemingly happens randomly as I have not found out a way to reproduce these spikes consistently
Changing brightness doesn't work
Does anyone else know what they are/have the same experience?
I really want to stem away from a refund considering how much work I have already spent on the phone.
Thanks,
Luke
Wow. What OS do you use?

Weird screen brightness? flickering on a game at a specific part

Hello, I got this phone around two weeks ago and I've noticed on these past few days on a game (Azur Lane) in the part of the Backyard that depending on how I move the camera the screen will get darker and when I move it away the brightness goes back to normal. It happens with high brightness, low brightness, adaptive brightness off and on. It only happens on this game and on another one which is the same issue on also a specific place / part of the game. Outside of these two games it doesn't happen, or atleast I haven't noticed it.
Here's a video regarding the issue: Since i'm not able to post it because I need 10 messages to do so here's the ID of the youtube video: pnAIrOZnIrQ
Thanks!

I have the same issue, most of the times it happens when I'm watching something on YouTube. I think it's some kind of automatic contrast setting. I've seen the same thing happen on some TVs and PC monitors and it happens when there's a lot of dark things on-screen.
I also have same issue on Liquid Remix. No good response from telegram group community.
