Screen becoming washed out while watching video or on power save - Transformer TF300T Q&A, Help & Troubleshooting

This has been discussed in a few places, but I'm wondering if anyone has a fix. This thread http://forum.xda-developers.com/showthread.php?t=1644348 discusses the software side, but veers off talking about inherent display (hardware) issues. The issue I'm talking about is almost definitely software.
Putting the TF300T into Power Save mode shows this most reliably. The entire screen takes a few seconds to fade to a low-contrast, de-saturated version of itself. Another way to reproduce this effect is to be in Balanced or High Performance mode and to simply watch any full-screen video, like those from m.youtube.com. I believe the Flash Player is exempt from this issue, since it doesn't engage the h.264 hardware decoding, but that's speculation on my part.
My question is this: is there any way to disable this feature? I get why they did this, but the benefit isn't worth the poor quality video. There's a modified buid.prop people seem to be using. http://forum.xda-developers.com/showthread.php?t=1641219 Will that help my situation at all?
Thanks in advance for any help you can offer.

Responding to my own thread here.
This issue was fixed in the release of the official Jelly Bean firmware.
To disable this "feature" on the official Jelly Bean firmware, go to Settings -> Asus customized setting -> under Power Management uncheck Enable smart backlight adjuster (Auto-adjust the screen backlight based on display content to save power consumption).

[Q] Hack SCH-i760 Camera's "Continuous" mode to take more shots?

I have an i760 smartphone with a cracked screen that I want to turn into a sort time-lapse camera. The idea is to get it all set up using EveryWAN, start snapping shots and just let it run until I stop it or it runs out of battery. The result should be a continuous record of whatever event I leave it running at. It would be a cool way to record parties and events like that without having to run around with a camera in your hand all night.
I searched for a program/hack to do this and came up with a few things that will be similar (tinycam on this board) but I would like to try the continuous shot thing anyway as it has its own cool factor.
What do you guys think? Is this something that can be altered within the system files or is it set in stone with the OS? Looking forward to your thoughts!
No one has any ideas? I would think this would be a fairly simple mod though I'm not sure how this stuff works.
Bump Bump Bump It up!!!
So I've done some playing around and here's what I've come up with...
If TinyCam or VIO for windows mobile had better/ongoing support and were modified to use higher camera resolutions and effects, etc. I would use one of those in an instant. The problem is they're both limited to picture resolutions of under 200x200 and have no support for low light shots.
I played with the registry keys on the i760 but can't get any changes to take effect or remain changed.
HKEY_CURRENT_USER>Software>Samsung>Camera
I set,
PictureShotMode = 2 (multishot/continuous)
MultiCount = x (Works for 3,6,9 but nothing above the defaults)
This makes the camera start up in multishot mode but inputing values higher than 9 resets the shot count to the default 6 in the camera settings menu. So something is obviously handling this in a different way. Can camera.exe check these settings as it is launched and revert anything back to default that is out of its set range?
Anyone have any ideas on where I can go from here?

The thread of Known Issues

This forum seems to be really negative. And it scares people away. I don't want to start a thread that says "OMG, I love this phone so much" because nobody wants to read that and, well I don't love a phone that much. So I figure why not have a thread that has all the known issues? So people can have a better idea of what to expect.
Well, to start off, I want to say there is no perfect phone in this market. Every phone has issues. Anyway, you will use it for only 18 months and then throw it away. So don't act like you are making a life decision.
1. hardware related
(1) Random shut down.
Possibility: 1/5. Reported by some users. I personally never have this issue.
Solution: exchange for a new one.
(2) Poor battery life.
Possibility: 5/5. Don't have high hopes on battery because it is a huge smart phone. But don't freak out if it only lasts for 5 hours in the first day. It will get better (much better) after several cycles.
Solution: There are tricks all over the internet.
(3) Soft key backlighting isn’t tied to screen timeout
Possibility: 5/5. Soft key backlight time is about 2s. It can't be changed, no matter what the screen timeout is.
Solution: none.
2. software related
(1) Performance Lag.
Possibility: 4/5. As powerful as this phone is, you will feel sluggish once in a while. For example, transition delay, touch response delay. Most annoying: phone freezes when installing apps from the market.
Solution: by using Launch Pro or ADW, you can have a better and smoother experience. But the phone still freezes when installing apps. All you can do is to wait for the installation to finish. Things might get better after the 2.2 update. But there is no official date for Froyo in the US market yet, so I can't say that's a solution.
(2) GPS
Possibility: 4.5/5. Seems like lot of users have this problem. Few users claim theirs are fine.
Solution: None. Samsung promises a fix by the end of Sept.
(3) Sideload apps
Possibility: 5/5. You can't install out-of-market apps.
Solution: You can root. If you don't want to ruin your warranty (I don't), you can use Sideload Wonder Machine. I used it for Genie Widget and Angry Bird. Both worked fine.
(4) Calendar
Possibility: 5/5. When adding an event, the default calendar is the locally "My calendar". And it won't get synced to your online calendar. You have to manually change it to your gmail calendar EVERY TIME.
Solution: none.
(5) Browser brightness setting
Possibility: 5/5. There is a separate brightness setting for browser. It could be annoying when the screen has different level of brightness.
Solution: none.
(6) Music player
Possibility: 4/5. Stock music player doesn't recognize playlist. You might be frustrated to find an alternative one. you may have to pay for a music player.
Solution: I want to say none. You can always find one in the market. But it was not a pleasant experience for me.
(7) status bar trick
Possibility: 2.5/5. You can slide on your status bar to change the brightness. It could be a welcome trick or annoying feature. Screen brightness is so important to your precious battery life, sometimes you don't want to accidentally slide on your status bar.
Solution: none. You can love it or hate it.
I just want to list all the issues that you'll have. Potential buyers can make their own judgement. Please reply if you can think of any other problems. But please don't say things like "you can always root" or "flash your rom", or "there is an fix coming soon".
[update] A lot of the items I listed were not defective issues. But they could be complaints. They could be something you don't like and you can't find a way to change. And i don't care if it's from AT&T or from Samsung or from Google. As long as it might be a problem, I am listing it here.
Calendar:
Does not recognize phone numbers or URLs in any part of calendar event (no click to call or launch web page)
Contacts:
Looking up GAL contact (global address list) only available from compose email screen, and only returns email, not phone number.
Email:
No control over which folders sync (Exchange); No select all option; other minor issues

Agreed. Most new phones especially complicated ones have issues. But it would be nice for it to work as advertised.
We don't really know yet if some of these are software or hardware. The GPS issue for one looks like software but may turn out to be hardware. Too soon to tell. Let's hope they have a real fix for it because even though it is not critical, it is a useful multi-purpose tool that many of us rely on daily. I expect it to work. I am patiently waiting for the promised fix but if it doesn't prove reliable, I have to find a different phone.
Random shut downs. I returned one Captivate because of this. Again, hard to tell if its hardware or software but I am assuming hardware and returned mine.
Poor battery life. Not as much an issue as it is a relative expectation. Seems a lot of the faster Android devices and even the IP4 run out of juice pretty quickly. My BB 9700 will last twice as long but maybe that's because the screen is half the size, half the resolution and half the brightness.
Also, a handful of Captivates have a problem getting into recovery/download via the three button method. Only a handful as of now.
As for the software issues... well, let's hope we get plenty of good ROMs from Samsung and plenty of modded ROMs from the smart folks around here!

ok well I want to address these one at a time
1) random shutdowns - true, seems very hit or miss on who it affects and how often.
2) poor battery life - I have to strongly disagree with this. almost everyone seems capable of eeking at least a day out of their battery even with heavy usage. if you aren't getting at least a day, either the battery or unit is defective in some astounding way or you're using GPS while streaming videos for 7 hours a day.
3) soft key timeout - this isn't an "issue." if the iPhone 4's antenna thing is a "total non-issue," so is this. it may not be the most sensible decision to have them on different timers (it would be preferred that we could manually set this), but this isn't an "issue," this is just personal preference. I personally don't mind it at all since I rarely press them when I'm using my screen, and if you truly use this phone, it isn't hard to remember where they are
1) performance lag - true, but I'm kind of willing to believe a lot of this will be fixed when froyo is released. to me, it's pretty obvious samsung is working on this since the JH2/JH3 builds are way faster than JF6 without any modifications.
2) GPS - definitely an issue I can agree with. Samsung should have been on this faster (even the Fascinate users are claiming issues already). they should have rolled out of a fix by now considering how many phones they have out there in the world.
3) sideloading apps - seriously? this isn't Samsung, this is AT&T. If you've got an android phone on AT&T, this is what you're going to have to live with without personal modification. don't like it? stop being on AT&T
4) Calendar - can't comment, don't use
5) Browser Brightness - again, a non-issue. you can use the slider bar to change it on the fly (which is a massive improvement over other android phones IMO) or set it to whatever you'd like
6) Music Player - can't comment, replaced with stock 2.1-update1 music player for personal preference
7) status bar trick - I don't see how this is even considered an issue. if you're manually setting your brightness, does it make more sense to do this or go into settings, sounds and display, brightness, and adjusting it there to change it right back moments later? no. I personally think this was a brilliant move on samsung's part. I keep my screen on the lowest brightness almost always, and then I realize I need to turn it up because the sun is too bright, so I can just fix it instantly by pulling it down, turning it up, and then turn it down when I'm done. if you're doing automatic brightness, this "trick" doesn't even work
edit: I'm just saying that if you're going to bash the phone for these issues, let's agree what is actually an issue and what is just user-preference related

I agree - separate bugs that affect 90% of the phones from other variables.
My phone has never rebooted or shutdown on its own, and it is not something 90% of the people are complaining about - unlike GPS.
Battery life is subjective and based on usage. Compared to my iPhone it is about the same. BB - definitely better, but as mentioned the screen is smaller, and BB controls the sync settings - so not a fair compare.
Music player has a workaround for playlists - move music to phone, go to recently added playlist, select all, create new playlist. Not ideal, but a different way to do things. There are free music players too.
Some things - like the soft key lights - are sort of a gray area - is this a feature implementation or a bug? Probably a feature issue. It is easy for one person's feature request to be another person's bug report.

What I am trying to do, is to list the issues (or complaints if you will) that have been posted. The issues I listed might not necessarily be defective of the phone. They were the things that may raise your eyebrow. I tried my best to be objective.
In terms of user-preference, I won't post it if it is really user-preference. The issues I listed, e.g., status-bar trick, brightness setting, they are NOT configurable. If you like them, great. But if not, sorry there is NO way to change them. That's why I list them as issues. I want to list all the potential issues/complaints so that potential buyers have a better idea what to expect.

OK, i got you. But some of these issue/complaints are from a vocal minority and I would say they unfairly describe the captivate - especially things like battery life and random shutdowns. Battery life depends on what you do and where you are located. Reboots are probably a hardware issue involving a small group.
IMHO if you are going to mention hardware issues that affect an uncounted minority, then you have to add all the weird stuff people have returned phones for - speaker not working, screen pixel out, volume switch, etc.

Well, if there was a loooong thread about screen pixel or speaker, I would have listed them already. Unfortunately, I only see several threads about random shutdown. I did list it as low possibility though, meaning it only happens for a very small percentage of users.
Would there be any merit to posting some of the individual issues as their own thread with a yes/no poll, so that we can see relative numbers about how many people are being affected by a particular problem. Granted, it wouldn't be "scientific data" as the typical poster to those threads would probably be users looking for the info or having the problem, but still...
FWIW, I have a Captivate that is going back today due to the randon shut down problem. Funny enough, the GPS works perfectly.

[Q] issues in video recording and display

Hi..
When i'm recording the video i see these black horizontal lines moving upwards which is really annoying. I've been facing this problem from my first video recorded. And the other issue with display is when i open options menu on any white/light colored background(specially during browsing) i notice the screen flickers.This problem disappear on high or very very low brightness.I'm using the device for two months now.Anybody else facing or faced such problems.What is the solution to this?
Me too :-(
Any solution?
Sent from my GT-I9103 using XDA App
Well what i have discovered with the video recording issue seems to be with the fluorescent lighting. I've tested it very well and turning on the tube light (fluorescent lamp) causes the dark rolling lines in video. Now I want to know if this occurs only in few mobiles with any particular bug? Can you guys check this and confirm? Also is this a hardware or software related bug?
And i still don't have any clue about the display flickering on touching the menu and back options area of the screen.
Any help would be of great use to solve this issue.
Regards

Are you using the stock ROM. Did you ever try other ROM's and test if this was a software bug of stock ROM?
To solve screen flickering problem you can go to Settings -> Display, and uncheck "Auto adjust screen power" option. I guess this option works like "dynamic contrast" option in PC monitors, by lowering screen brightness in some scenes. This may save some battery life, but the side effect is screen flickering during some animations, etc.
And I think that issue with fluorescent light occurs on a lot of digital cameras.

Thanks a ton dude.. Disabling that feature feature really did a trick for LCD flicker. Yeah i've seen that black rolling lines in a few other camera videos but when i record videos, they appear so dark and distracting.. Its all the black lines rolling upwards and I have to delete that annoying video immediately. Also I read it has to do with the frequency of lamps in asia etc etc.. Can a few of you guys check this issue and clarify.

Screen Standby (HDMI out + Black Screen FTW!)

As I'm sure many of you know, HDMI mirroring on the Infinity works well, but having two screens on while watching a video or playing a game is distracting.
Screen Standby is a new root app that disables the backlight on your tablet or phone while still allowing touchscreen functionality to remain active. That means while your tablet may look off when outputting to HDMI, you can still use it to pause, change apps, and do whatever you want while saving battery life at the same time. To turn your display back on simply shake the device. Unfortunately the proximity sensor function isn't working at the moment, at least on CM10.
I'm surprised it's taken this long for an app such as this to come along, but I can confirm it works on our infinity and on CM10 as well.
You can find it for free at the play store here: https://play.google.com/store/apps/details?id=com.nkahoang.screenstandby
and the XDA thread here: http://forum.xda-developers.com/showthread.php?t=1934495
And I would suggest you turn on two-stage screen off as that allows you to switch to whatever app you want to run before you go dark. Hope this helps!
Interesting... I've been wanting something similar to this. Think I'll be trying it out once I get my cable.

Input lag and possible fix (works for me).

I don't know if anybody else here has suffered this, but I've read several times when googling, that many XZP devices came with input lag out of the box. My device has always suffered with this, and flashing custom ROMs didn't seem to make a difference.
Input lag means that sometimes, keystrokes/touches are completely missed and sometimes scrolling misses too.
I unlocked my bootloader really early on, so I never wanted to send it back as I'm sure this voids my warranty.
I tested for a faulty digitizer using various screen input test apps from playstore, and they usually don't show any areas of the screen as faulty. This has always made me believe that it was most probably a software issue.
Today I discovered that yes indeed, my issue is definitely a software issue.
THE FIX:
Changing the screen resolution to 4k (3840x2160), and DPI to 821.
I've tried this before but never noted the difference in touch input. Perhaps because I wasn't looking for it.
Today I tried it again and much to my surprise, this time I noticed a HUGE improvement to input sensitivity and for now has 100% alleviated the problem. Typing, tapping and scrolling works perfect now.
This is most likely caused by the screen having to rescale pixels from 1080p to 2160p, making extra work for the CPU, but I'm no expert so I might be wrong. But it works for me.
I'll also note that I'm using Turbo ROM p75B now, and the input delay was still there until changing the resolution.
I'd like it if somebody who has suffered the same issue could provide feedback, I really hope this helps you too, as this was the only real issue that have me buyers regret, and it now works wonderfully.
Cheers.
Edit: I do believe this topic might be better recognised in the guides and discussions category. If so, could a mod please move it there.
Luckily I haven't had this input lag issue. However, I do get input lag if I have stamina mode turned on, and set to battery time preferred.
Just so you know, you do know that you're only emulating 4k, right? The only way to set the display to 4k is on AOSP.
@iKlutz I can't seem to find the resolution settings lol
Yes I understand that it's only "emulating" 4k and that it's not native 4k. It also uses more battery, which would suggest higher CPU usage, which in part contradicts my theory about rescaling causing input lag.
Perhaps it is something to do with the "touch map" (I can't think of the term), the software/grid that maps out the touchable area to the digitizer, having to resize from 1080p to 2160p, making the grid inaccurate? But it wouldn't make sense as to why it only affects some devices.
Also, I do not have stamina mode enabled as it's almost pointless in today's phones. I believe limiting processing speed only makes process queus take longer to finish, which means that CPU takes longer to idle. It only saves a negligible amount of battery unless your phone screen is off for 80% of the day. Almost as pointless as closing applications and cleaning RAM, as your phone will just use more battery rebuilding caches and restarting processes.
In any case this has completely alleviated the issue for me, so I hope someone on Google ends up here and this may be a solution for them too.

There are some threads here that explain various methods to change the VM resolution and scaling. If you're unfamiliar with ADB, I suggest you read very carefully and take precautions, as setting the resolution wrong could make it really difficult to reverse the procedure and we currently don't have a way to make TWRP backups.
i noticed this too.. but i enabled glove mode and things sorted by it self..
this kinda works, it happens very much less frequently but it does still happen
