[Q] eMMC Burst Mode - Galaxy S 4 Q&A, Help & Troubleshooting

Devs, can this mode kill SDCards with low class (C4 or C6)?
For S4 are recommended use C10, for burst photo and FullHD movie.
I have 3 SD 32GB C4 died.
Burst mode, in other devices send data to device (hd/ram) without wait a received data.
If device send a lot of data to SD, and don't have the capacity to write all and respond to device, this will warm and later dies.
Are possible disable the burst?

[Q] Speed of Focus with Memory Card Installed

I was wondering if anyone has done a test of a Focus with and without a memory card installed for speed. There are Youtube videos showing that the Focus will boot into games faster than the HD7. The thought seems to be that the HD7 is using SD cards and the Focus is using NAND memory.
If you install an SD card in the Focus does it slow down because it is now also using SD memory and that is now the bottleneck?
When I installed a class 6 16GB MicroSDHC, I did hard reset via the att website instructions, not the quick guide ones. It showed around 22.?GB of space. I got errors when trying to use Netflix, YouTube, and few other apps. When I powered off and back on my memory was wiped, and it showed around 15GB space. I din't have time to notice speed. As far as browsing the phone it didn't seem different with or with out memory.
If WP7 truly stripes the data between NAND and micro-SD, it should be faster with the card as long as the SD card is not twice as slow as NAND memory (assuming you use an 8GB card). Would like to hear the real life results though.

[Q] [Transcend] [MicroSDHC 16 GB] Problems running Android proper.

Hi XDA devs,
Yesterday I was happy to receive my new microsdhc card 16 gb class 6 from the Transcend brand.
I copied [JAN 26][REL]Cope's SD HD2 Gingerbread/CyanogenMod7 from my old card (Scandisk class 4 8 gb) to my new card.
Then when I started haret it took much longer to boot. Once in Android it took a long time to load my apps and widgets. I turned off the screen and tried to turn it on, but the whole thing was stuck. I had to take the battery out.
This morning I tried to boot again, and I faced a new weird thing: after a long time watching the boot animation it showed me the Welcome to your HTC HD2 setup wizard. It was like it had created a new data.img but it didn't, all my apps were still there, only my Home and settings of the phone were gone.
Then I tried to copy my old Android (2.2) to my new card. Faced the long boot time again, and it took again a long time to load my apps.
I noticed that when I only have the Android folder on my sd it boots a lot quicker, but when I'm using up more space it starts to face problems.

How can it be disabled? I'm using a card reader on USB which doesn't has a lock function.

I'm thinking of returning this new card for another card from Scandisk (32 GB class 4).
Will this card work proper?
What do you think, is there any change my new card will function as it should?
<EDIT>
I just did a fresh install and everything looked fine, fast and stable. I'm going to reinstall my apps by the use of TITANIUM backup, let's see what happens to the speed.

[EDIT 2]
When transferring all my data back and set back my apps: minor change. Anyone got a solution?

[Q] Low video camera FPS

Hi,
I was having some problems last week with an unresponsive UI and some people recommended rooting my phone and using a different ROM to solve the problem, others just said to factory reset my phone and re-format the SD card.
Well, I factory reset my phone and re-formatted the SD card and this has pretty much solved the slow UI problems (for now) and I thought that it also might fix another problem that I was having: unwatchable low camcorder FPS.
It doesn't matter what resolution I am recording in but the FPS of video is usually around 8 or 9 (according to my computer when I transfer the video file) and if you watch it there are like 2-3 second "hiccups" during the clip where the video is just frozen but the audio continues normally (this is during playback on the phone and on my PC).
I thought maybe I had a bad SD card and the re-format would fix it but it didn't. According to my SD card testing program it has a write speed of 5 MB/s which seems like it should be adequate.
Is there something I can do to fix this? Do I just have a bum phone and need to call and get a warranty replacement?
Any help would be MUCH appreciated...

Video Camera lag + freeze

I have read numerous accounts of people being disappointed with the video capability of this phone. I have experienced numerous times that while taking a video the video will temp. freeze. After some trouble shooting with different kernels, ROMS, camera apps, and everything else i have found the reason for this freezing. It seems that if you use sd card for storage by selecting choose sd card storage within the camera app the video will always have tendencies to freeze do to the write speed limitation of the sd card. I have a 32gb class 4 and the write speed is not enough for the high quality video to write without problems. If you are fortunate enough to have a class 10 this may not happen. I have also found that selecting internal memory when using ROMS such as CM7-CM9 although CM9 does not have a working video camera yet, the problem is not present. Just wanted to share for those who bash the Atrix but won't go to another phone and stop *****ing.

How long until this kills my SD card? (Running OS off SD, tons of read/write cycles)

Considering LineageOS is running off the SD card and performing tons of read/write operations all the time, how long is my SD card going to realistically last? I've killed quite a few by hitting their read/write cycle limit. Just wondering if this is a three months of use before your SD card is dead type situation.
i use 64GB mSD for CCTV video recording. It runs 24/7. Its dead after ~3 years. I think LOS will have way less writes than that CCTV.
