If anyone finds any more useful settings that can be changed or settings that work best, post them here. ;)

ABSOLUTE BEAUTY.

I knew about 90% of these on the Desktop version, don't know why it didn't click it may be the same on Tablet, BOOKMARKED for Later, THANKS!!
[Nexus 7 General] prestige777:
It's rather ironic, that this is the only real desktop browser on android, yet most of the desktop settings aren't enabled or set by default. This is only browser that I have ever used that I can use all day on flash heavy sites and never crash. I've only had one FC in the past month.
[Nexus 7 General] Wilks3y:
Yeah FF is hands down a quality browser, I'd be using it on Desktop if it wasn't so weird about my Cookies (never keeps me signed in on Forums[XDA] etc)

But I can't believe these options are just as usable on desktop, and yeah, even without these settings enabled I must say FF has never crashed on me on my tablet (even with flash heavy sites as you say).

Whereas Chrome just stutters, cries and gives up.

Boat just freaks out and FC's

Dolphin just isn't my pick.

Opera I don't like at all.

SO WEEEE Thanks for these tips my friend !
[Nexus 7 General] prestige777:
No problem, if you have any good tips or variations please feel free to post them here. ;)
[Nexus 7 General] SkyandDirt:
Thanks for the post, very interesting.

I applied your tips to firefox running on my Nexus 4, but I did not see much of an improvement. Just doing some casual/typical browsing that I would normally do it felt almost the same as before without the tweaks, although I wasn`t doing any timing with a stopwatch or anything of that matter so I can`t say for sure that there wasn`t an improvement. Maybe these tweaks would benefit lower/older end devices more than the newer high speed quadcores.
[Nexus 7 General] prestige777:
Its really noticeable when you start with a fresh install of Firefox with no data, once Firefox starts collecting data it starts really slowing down. Firefox really needs to deal with this data collection issue. For me it collects over 100mb of data in just a couple of weeks despite clearing everything from within the app. I don't think most of settings affect Firefox's performance if its not being used with a desktop user agent since that is handled completely different than if you're using the default android user agent.
[Nexus 7 General] RobPitt:
This is not true, general.useragent.enable_overrides has no effect on general.useragent.override (which is always enabled) and instead affects overriding the User Agent on a per-domain basis as described here.

You should tell people the integer is the cache size in KB. My config already had this setting and it was set to 1024. According to mozillaZine, the default is set according to RAM size but as mine defaulted to 1024, perhaps this is different for mobiles. Setting it to your apparently random value of 18432 could work, but after reading the tweaks page you referenced and mozillaZine, I opted to set it to -1 which should let Firefox decide according to how much RAM I have and if it follows the table in mozillaZine, will make a substantially bigger cache than you suggested.

Thanks for bringing my attention to these useful features.

If you lower the screen brightness all the way down and open the stock internet to Google, and tap the search bar to pop the keyboard up, you'll see a slight flicker. So far on every display s4 at the store has the same problem. Anyone have an idea if this is software or hardware related?

I've noticed flickering on super white backgrounds. It's hard to see and it's got to be the right lighting and high brightness. IMO if you need to go through a process to see a slight flicker, blobs, etc., it's not really a concern. I'm assuming it's software related.. Same with the text blur.
[T-Mobile Samsung Galaxy S 4] dannyyyyy:
Is your brightness ALL the way down to? Thats when you notice it.

I did notice some change in the brightness when the keyboard shows up. But not flickering.
[T-Mobile Samsung Galaxy S 4] dannyyyyy:
Well yeah thats what I mean't by flicker lol. I honestly think the oled screen samsung put in the s4 is a little faulty and they needed to calibrate it better before shipping.

Confirm that besides smearing I also have so called flicker on white or bright backgrounds sometimes. I think that this is the new OLED screen issue and it cannot be fixed :( :(
[T-Mobile Samsung Galaxy S 4] Towle:
I think it could even be software related. A much bigger issue I've came across on 3 different s4's is the entire bottom half off the screen having a terrible pink tint.
[T-Mobile Samsung Galaxy S 4] pezlomd:
How noticeable is the pink tint?
[T-Mobile Samsung Galaxy S 4] Towle:
It was very noticeable. Especially in apps with white backgrounds, such as the dialer.

Screen flickering issue
[T-Mobile Samsung Galaxy S 4] mordeous:
I do also have issues with screen flickering when the device is used outdoors, and exposed to daylight. The flickering appears in any application (sms / browser) when the keyboard is flipped up - It disappears again, when keyboard is dismissed.

I made a small video of it - Please notice around 00:22 how the flickering starts and stops

I have the AT&T variant. Went into the sun today for the first time since getting it and I noticed the very noticable flickering at full brightness with apps with brighter backgrounds (aka google hangouts). Pretty annoying.

Not present any other time.
[T-Mobile Samsung Galaxy S 4] :
It's a software thing guys, no worries.

Use AOKP or CM 10.1 and then try it. Doesn't happen at all.

Software update will fix it or someone will hack it up :)
[T-Mobile Samsung Galaxy S 4] Simoleon23:
I can confirm the issue (I9500). It occurs at any level of brightness but is negligible at maximum brightness and most obvious when the brightness is set to minimum. To reproduce the situation, bring up your keyboard, preferably in a white background (for instance, twitter), you'll see the screen is brightened up. Also happens and is visible on dark backgrounds, go to Message app, bring up the keyboard and you'll see the screen looks a bit washed out as opposed to when the keyboard is minimized.
[T-Mobile Samsung Galaxy S 4] -sandro-:
I noticed another thing instead, when on white backgrounds it happens that I see some kind of interference lines that move vertically (like a radio interference), I saw it twice in a one week usage and I was indoors under fluorescents lights.
[T-Mobile Samsung Galaxy S 4] Red89:
I have the same, is the gsm antenna, when you are connected with mobile data with gsm and the signal are low the screen light flicker.

I noticed this yesterday for the first time since owning the S4 since launch. It was a bright day outside, I had the brightness set to auto and there was a noticeable flicker. Haven't noticed the issue in any other scenario.
[T-Mobile Samsung Galaxy S 4] nightfox11:
don't worry guys there's a new update coming (already out in Germany) which fixes this issues and Give the user the ability to Install apps to the SD card !!!
[T-Mobile Samsung Galaxy S 4] ker0zene:
Note, the new Apps2SD function doesn't move App data, just the APK.. so while it's nice it won't be very effective for large game files, etc
[T-Mobile Samsung Galaxy S 4] PsychoDude:
I have that issue too.. It only happened to my 2nd set when i swapped it out because of pixeling leaking issues. My current set has this distracting waveline thing when calling up and hiding the keyboard. It always happens on white or light blue backgrounds which did not happen on my 1st unit.
[T-Mobile Samsung Galaxy S 4] Davies_90:
I get the same problems when using the auto brightness feature. To solve it temporarily I disable it and manualy adjust as needed. Mine is quite extreme..when it tries to adjust it does it in huge jumps. Its too coarse imho.
[T-Mobile Samsung Galaxy S 4] JUSMEJOSE:
My screen flickers a little when im watching youtube ..

>O/C GalaxyGS4<
[T-Mobile Samsung Galaxy S 4] crazy talk:
The reason for the 'screen flickering' is related to Samsung capping the display brightness depending on the APL levels of the screen.

Basically the phone changes the brightness regardless of user setting depending on what percentage of the screen is displaying white. this is more pronounced in the browsers to boost battery life numbers in reviews. and unclamped in some screen testing utilities to get the big brightness numbers to compete against LCD phones.

READ ME

Some custom roms may have turned this off. Don't know for sure though.
[T-Mobile Samsung Galaxy S 4] Donalddesu:
What reduced the flicker for me was changing the adapt screen mode. I only get it when the keyboard comes out on browser, dialer isn't so bad. Anyway guys give it a try might help reduce some of it.
[T-Mobile Samsung Galaxy S 4] :
Impossible to turn this off unless your in an aosp rom
[T-Mobile Samsung Galaxy S 4] Davies_90:
Being that I've only had my phone for less than a week it may just need to be "Ran" in. Ove flashed ARHD 3.0 and still occurrent.
[T-Mobile Samsung Galaxy S 4] Bacon Rage:
I have a similar issue but not exactly the same and I have been trawling the net to find anyone with the same issue. This was the closest thread I could find so I thought I would ask.

My phones screen will flicker randomly and it can happen at any time, even if the phone is on the home screen and out of the sun. The flickering causes whatever I am doing on the screen to be reset...so for example if i am typing a message and the screen flickers, it minimises the keyboard and often causes me to click send or completely deleting the message before it is complete. It is probably the most annoying issue I have had on any phone ever, I cannot type a whole message without the screen resetting itself. Anyone finding this same issue or am I the only one?

Thanks!
[T-Mobile Samsung Galaxy S 4] tigerfire25:
I am having this problem for quite a time now and all the latest firmwares that I have tried have this issue on my phone, I was able to find that it happens only when on mobile internet. seems to be a software bug but have to find a solution for it, what i think is that it might be a conflict of some modem versions with certain screens on some s4s. Did not had this problem at start, it started happening after I flashed some custom roms based on latest release so that makes me believe that flashing an old version rom might fix it for now.

My phone is KSA i95000 so for now I am trying different official roms released for KSA.

The latest ROM gives me the flickering issue.

The oldest I found is Build Date: 23.04.2013 -> Region: KSA (Saudi Arabia) PDA: I9500XXUAMDK, flashed it and I was unable to get mobile signals! also flashed kernel and changed modem but problem persists, Now to Next official ROM but hey I found was trying the wrong modem so now downloading the correct modem and will try this one another time.

Now downloading Build Date: 29.05.2013 -> Region: KSA (Saudi Arabia) PDA: I9500XXUBMEA

will appreciate if someone else can try some different roms from the thread link below and provide feedback

[T-Mobile Samsung Galaxy S 4] RJM7787:
Yes I had this issue and it was quite noticeable while I was out in sunlight. From what I can tell, after making 3 adjustments, the problem is gone (or at least for my eyes). The problem lies with samsung's auto adjustment settings, the adjustments take place in intervals which appears as flickering (rather than smooth transitions).

1. Disable auto-brightness

Go into settings > my device > display

2. Disable auto adjust screen tone (makes a big difference with flickering)

Go into settings > my device > display > screen mode

3. Disable Auto Display and select one of your choice, otherwise the screen continuously changes gamma/tone etc, and on white backgrounds like google it can flicker while making adjustments.

Note: the screen will end up using more battery life because of these settings.

Issue resolved for me!!!

Guys!!! Try the following post! It resolved the issue for me. I lost the flickering issue after removing the screw from the L1 area (near the vol "-" button) somehow it causes the phone to reeatically swithc to S-view mode causing the flicker. probably it is magnetized??? not sure .

Thank you so much. Talk about annoying.

One reason this forum is so great. This is the first result I checked in my googling of "s4 screen flicker". Immediate results. Love it. Thank you!

Edit: spoke too soon. Issue is still there. Less of a flicker though. It's more like the screen is changing shades. Happens most often on white backgrounds.

I have this problem. With very low brightness my screen enter in flickering.

In the phonehouse SAT they dont want to change me the screen because they dont know if the problem could be the motherboard.

Can anyone tell me wich cause this issue?

It is very annoying in night...

And I don't want to left them the phone one entire month if the problem it is the screen that could be replaced in 10 mins.

Thanks!

both are on same rom same everything almost identical except one is black and the other is white lol and the white one is giving the problems, on stock rom it was REALLYY BADD couldnt even use the phone, took it to samsung they couldnt help so i ended up rooting it flashed a custom rom and the problem dramatically reduced but is still present!

really unsure whats the cause

the problem phone is on a later firmware/baseband

but both are without the knox bootloader

really annoying problem

I have a Sprint GS4 which I bought at release a little under a year ago and just started noticing when the screen is on the charger and goes dim the screen flickers. I thought it was just me until I saw all these reports online. This phone also gets terrible notification bar burn in as I use it for GPS and music playing most of the day. I am wondering if I should have this phone replaced by Samsung while I am still under the 1 year warranty. I assume the new one they give me will develop the same issues anyway. Also, they will probably send me a refurb and my screen condition is pristine so I am worried about getting a lesser unit in return.
[T-Mobile Samsung Galaxy S 4] killerz298:
So the issue got progressively worse and I am approaching my warranty date so I contacted Samsung and they had me do a cache partition wipe. So far so good. I see the issue only so faintly and I don't think I wouldn't notice if I wasn't looking for it. I will see if the problem returns and if so, have the phone swapped out. I don't want to be stuck with a potential dud after the warranty expires.

I keep my phone in my desk dock all day and have developer options set to keep screen on when charging. After about 20 seconds of not touching the screen it gets dim (I asked Samsung and you can't disable this "feature") so for most of the day it is sitting there flickering.

galaxy s4 black edition i9500

My screen flicker only ever occurs while any kind of video plays in any app. So YouTube, video, Ted, and even the starting of Samsung group play cause crazy screen flicker in the video.

I've tried all of the following:

Switch off auto brightness

Switch off auto screen mode

Switch off smart stay and all other screen related rubbish

Switch off all Samsung features except those I can't disable

Reboot phone

Switch screen off and on again

Change power saver settings

And developer mode settings to force GPU composition.

Only rebooting phone works but only for a while. The moment i switch screen off and on again the videos start flickering again. Perhaps it starts after sleep mode?

Gives me a headache.

Update to KitKat did not fix this bug, i think the exynos is to blame. Maybe the low power A7 cores cause issues while switching.

Video is attached, plx to fix!
