I am getting an impression that my eyes are getting tired very much by using S4 (I do a lot of flash cards studying foreign languages).

Is it my imagination or somebody else is having similar experience? Are there any configuration options that might be used to make it easier on eyes?

I never had such problems with my old Droid Incredible but maybe I am just getting older.

Try these apps:

Twilight

EasyEyez

Lux Auto Brightness

I think you could also do it with Tasker.

And there is one for your computer called f.lux.

Hi,

I've moved this thread into the Q&A, Help & Troubleshooting forum as all questions should be asked here. The development forum is only for development.

You can find a list of a lot of ROMs here but the thread hasn't been fully updated. For any ROMs which aren't in that thread you'll need to have a look through the development forum and see which ones are suited to you :)

Has anyone tried the 2gb SD cards from A-data or the ones from Expansys? I would like to know if they're compatible with the qtek 9090.

They're supposed to be high-speed but I guess that won't make much difference if the device doesn't support this. Doesn't matter, I just want to know if it'll work or not.

Also, does anyone have any experience with the reliability of these cards? They don't explode after two and a half read/write operations or anything?

[MDA III, XDA III, PDA2k, 9090 Accessories] fraser:
In theory you should be able to use any size of card. The card itself handes the physical addressing, so things like the 137 GB limits of IDE should be a thing of the past. If the device has an issue with it, it's because the device is buggy.

[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] thinking21:
Hi,

Long story short. I had TWRP 2.5.0.2 with my SGH-I377 (Galaxy S4 AT&T). I used it to flash this GE ROM by Maddog (http://xdaforums.com/showthread.php?t=2340783)

After flashing, the ROM works just fine without issue. The Model Number in the about phone section however showed to be GT-I9505G, but I didn't mind too much since it works flawlessly in everyway. When I tried to update TWRP to 2.6.3.0, GooManager downloaded the wrong img due to this (it was my fault for not looking at the version before clicking yes). But now after reboot, i can't get into TWRP recovery anymore, it keeps saying "System software not authorized by ATT has been found on your phone". I was able to bypass by going to download mode and cancel to boot back into my old GE ROM. But now I can't seem to find away to get the correct TWRP version back on the phone.

I can download the correct img from this site, put it on my internal/ext SD, but I can't find a way to install it from within GooManager or from a File Manager.

http://techerrata.com/browse/twrp2/jflteatt

I need some assistance with instructions on how to install TWRP manually from an img file. Or from a tar file using ODIN if anyone has the link to necessary files and instructions on how to do it. At this point, it doesn't even have to be 2.6.3.0, I'll be just happy to get 2.5.2.0 back.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] Agent:
You won't be able to install it with Goo Manager. Head over the the TWRP website and find your phone that way, and grab the flashing zip file and just flash it in recovery. I had the same issue a few weeks ago.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] thinking21:
After some more digging, I was able to find a solution.

For anyone who runs into this problem...I was able to use Quick Flasher from this thread http://xdaforums.com/showthread.php?t=1694617 , then choose the flash a new recovery using the correct TWRP img

Everything is good now, I am able to get into TWRP recovery 2.6.3.0

http://www.teamw.in/project/twrp2/182

That's straight from the horses mouth there. I didn't read much into it, but it looks like they have a odin flashable version. Also make sure that the newest version of TWRP doesn't conflict with the ROM your using. I have read quite a few where the latest version causes issues.

Good morning, lovely HTC ONE owners!

Yesterday, I manually deleted a folder from my HTC ONE containing an important file. I have tried finding a software or app to restore that folder, but it seems that none of them can detect the symlinked pseudo SD card of the HTC ONE.

Is there any chance to get back my data? In the future, I will use the app 'Dumpster', which only throws files into a special trash bin where files can be restored if necessary...

[One (M7) Q&A, Help & Troubleshooting] SecUpwN:
Thanks for helping, guys. The HTC ONE doesn't have an SD card, thus only offering 32 GB of internal memory. I guess that part has no filesystem, correct me if I'm wrong.

Darn. Maybe it's gods will. For other peeps reading this: Install DUMPSTER to avoid deletion without being able to recover files.

Even worse.... I deleted storage/emulated/0 folder on my htc one

Ok. So check this ish..... I was tryna free up room on my htc one, so i went into file manager, was lookin for unnecessary stuff to delete, and thats when i notice.. Inside the emulated folder are 2 folders, one named "0" and one named "legacy" so after going back and forth one to the other... I realized that the same exact files and folders as the other, so my retarded asss deleted one thinking it was a whole duplicated folder. Ok, yeah, i messed that one up bad. How could i be so stupid? So i looked up some claims of some solutions, downloaded the pc software they swore would recover everything. Nada... Zip. Zero... What can i do? The htc one is no removable sd card or battery and my phone is not rooted.... Please get back at me on this...

[One (M7) Q&A, Help & Troubleshooting] SecUpwN:
Sorry pal, no chance to recover anything. If you continued to use your phone after erasing all of that, it has been overwritten multiple times already. To make sure such thing does not happen again, install ES File Explorer and enable the RECYCLE BIN in the options - thus, you can recover deleted files easily. And for cleaning your device, always use SD Maid.

Hello everyone!

I am looking to get a new battery pack for a trip across the county. I have gone through the reviews and have settled on two devices. The Anker Astro3 2nd Gen or the Anker Astro E5. I need help from the community to make a decision. Does anyone have both for a good side by side comparison? I know the E5 has more capacity but the Astro3 has higher efficiency, and they are the same price. I plan to use it for multiple devices. Any help or opinions will be greatly appreciated.

Hi,

I have been looking for weeks and weeks for a solution on how to have my 4.3 SlimBean Galaxy I9100G work with the dual sim adapter I bought from MagicSim.

I cannot use that adapter simply because STK is not taken into account in most of the custom 4.3 Roms I have flashed, in the hope I could use the STK functions in one of them.

For those who wonder why STK is important to African and Asian markets, and even to some European markets, I would point to this brilliant blog, titled "Android's Achille's Heel: The Sim Toolkit": http://j.mp/19GUNii.

The author says:

I have sent tens and tens of emails to Rom cookers, to teams such as Slimroms... in vain.

It is really frustrating not to be able to use such a wonderful thing as a dual sim adapter because your rom does not support stk.

The solution would be to downgrade to a stock Rom for my I9100G phone... It's not really a solution.

The solution should really come from developers, who should have in mind the needs of users from around the world...

I hope this post will help advance the cause of STK among Rom developers...

So i have been looking for custom roms on many different websites, but there isn't one that i would say "this is the one" rom.

I have been think for what kind of rom i want for my GT-I9500, and here are some ideas that i came up with.

1) I have the google nexus 4 as well and the screen color on it looks amazing. Every time i switch on the phone, it just makes me want to look at the phone long. So maybe a rom that can make the screen color on the s4 better looking. (i don't know how to describe it)

2) I kinda like some of the samsung features like the multi window, quick glance, air browse, air move, air call accept, the palm motions, s beam.

3) On my nexus 4 i flashed the PAC-man rom, and i like it too.

4) I saw that some people can finish entering their pin and unlock the screen like the iphone without clicking ok/enter.

So maybe some developers can combine all these features and make a new rom, so for the people who doesn't want to get ride of all the samsung features and have many good features from the other roms.

If there is some kind of rom is like that already, can someone tell me the link? Thank you ~:D

I think many of us here on XDA feel that combing AOSP with Samsung features would make a very cool ROM, however most of those features are Samsung proprietary features, so unfortunately it won't happen :(

Good idea but sadly there will always be a line between AOSP and Touchwiz.

However DSA came very close with his BlackBox ROM, it's Touchwiz but has a AOSP look and a few cool features.
