[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] {Diemex}:
How does used ram cause battery drain? It does not. What causes battery drain is when your cpu is getting used. When your apps aren't precached your cpu will have to work a bit harder every time you start an app. Also your memory monitoring app will use more cpu cycles than it will save you. What you could look out for are apps that consume lots of cpu power. Sometimes apps are badly coded and consume lots of power. Those kinds of apps will most likely show up in the battery stats in the settings menu. No external apps are needed. They usually cause more harm then good.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] blckstr:
Yes maybe you are right. I managed to improved battery life. But I can't say the same for RAM usage.

Compared to my Sony Xperia Z1, Samsung Galaxy Note 10.1 2014 responds real slow. Although it has more RAM. (2GB vs 3 GB)

I did a research about speeding up it. But couldn't come up with a sollution.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] {Diemex}:
More ram doesn't really make a device faster. Nowadays it's a lot more about the software and drivers etc.. Samsung sometimes neglects that and focuses on adding software stuff that they can advertise. I wrote a guide on speeding the device up. It assumes you have root, but you can just see how many apps you can disable in the settings. Might be enough.

After applying all the steps and keeping my device clean it's the fastest tablet I ever had in my hands.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Medy89:
More ram usage is a sign of more services running.... which means there is loads of stuff running in your background..

If I dont run a single app my ram has 1.3 Gig ram left... go to application manager and check whats running... if you see stuff you dont need freeze it with titanium backup.. or unistall if you are sure its not needed.. your system does not simply use more ram randomly...

RAM is there to be used. Free RAM is useless RAM. The more RAM it's using, the lower the battery usage because it doesn't have to go to flash memory for data.

I found the problem. It is TouchWiz.

After disabling it and installing a new launcher, Nova Prime, I have no ram and lag issues.

Yes I agree about ram thing but with a huge amount of ram usage multi-tasking is not efficent.

Been running Nova Prime with Lag for several months, still lags. Disable the card reduces the lag a bit. That though is not an option.

Hi everyone,

I'm happy with Android 4.4.2 update (4G LTE finally available for me), but this update surprises me every day. Not in the good way every-time. Now I have problem playing Real Racing 3. Front touch buttons don't hide (no problems in 4.2.2 as I remember). Any thoughts?

I have the SGH-M919

I've rooted my phone and was running a GE rom

Everything was fine for MONTHS

Got in my car and plugged my AUX cable to my phone for music and the phone froze.

Force rebooted the phone and it started boot looping.

Rebooted to recovery (TWRP) and TRIED to wipe dalvik and cache and it FAILED, said it couldn't mount dalvik

Rebooted to recovery again and wiped all partitions and this time it worked so I proceeded to re-install GE rom, still bootlooping

Came home and tried to use ODIN to flash M919UVUAMDL and it failed.

Tried ODIN to flash M919UVUEMK2, also failed (sorry don't have the error messages right now)

Rebooted phone into download mode again and phone said there was an issue and to use Kies to recover

Installed Kies and started emergency recovery and that went through fine and the phone finished and STILLLLLLL BOOT LOOPS !!!!!!!!!!!

Copied the file that Kies downloaded (M919UVUFNB4) and tried ODIN again to flash that and it flashes fine but STILLL BOOT LOOPS

Obviously my Knox warranty flag is tripped and I don't have the money for the insurance right now.... so PLEASE FOR THE LOVE OF BOB

does anyone have any other diagnostic tips or tricks

to help me figure out why the F this phone is boot looping.
[T-Mobile Samsung Galaxy S 4] avelis26:
53 views and no replies.... come on people... someone HAS to have something that might help..

Anyone know if ANY possible way to reset the knox warranty void flag ?
[T-Mobile Samsung Galaxy S 4] lalec:
Only Samsung can reset your Knox flag. You can't expect instant responses here. People read and answer the questions they know how to. Not doing a full wipe before installing a different ROM often causes soft bricks and bootloops. I would start there although that doesn't explain why you couldn't mount Dalvik. Try a different recovery. Many people have had trouble with TWRP. Philz Touch works well if you haven't already tried it.
[T-Mobile Samsung Galaxy S 4] cybervyrus8587:
I literally just had the exact same problem as you. I googled and found http://xdaforums.com/showthread.php?t=2265477, then googled some more and found my .tar file for my phone, then odined back to stock 4.2.2. It took 20 min.
[T-Mobile Samsung Galaxy S 4] avelis26:
1. Samsung WON'T reset my flag... they won't even TOUCH the phone in any way shape or form. I spent almost two hours dealing with them and being honest about the situation. And they STILL won't do anything at all. The rep I was speaking too even said the first thing they do is check that flag and if its popped, they put it back in the box and send it back with no further action. So I will not buy form Samsung ever again.

2. I'm not expecting instant responses at all and nothing I said should have been interpreted at such. I made the comment of 53 views in 4 hours and not a single reply ... I was hoping for a better ratio of responses than that.

3. Where are you getting "Not doing a full wipe before installed a different ROM..." I never said that I didn't... and if you read what I took the time to organize neatly, I specifically state that full wipe was what I tried BEFORE re-installing the SAME rom.

4. Can't try a different recovery if I can't even get the stock factory image to do an initial boot.
[T-Mobile Samsung Galaxy S 4] avelis26:
Which one did you flash ?

[T-Mobile Samsung Galaxy S 4] avelis26:
Sooooo umm what ?

Anyway... I flashed PhilZ on my phone, did full wipe, tried installing the same GE rom I was using... didn't work.

Tried installing stock rom, didn't work.

Tried flashing M919UVUFNB4 via ODIN... and it flashes fine but again, first boot wont work.
[T-Mobile Samsung Galaxy S 4] avelis26:
Ok so .... I guess installing PhilZ... then full wipe, then flashing M919UVUFNB4 TWICE back to back did the trick.... no freaking clue how but it worked :)
[T-Mobile Samsung Galaxy S 4] avelis26:
I spoke too soon. Went through first boot. Got all the way to the end setup and then it rebooted on its own ... and now its stuck in a boot loop again :(
[T-Mobile Samsung Galaxy S 4] TigerDNA:
Since your using philz, choose install new ROM, then go to advanced and wipe dalvik, THEN go to mounts and select the one close to the bottom, wipe SD/data or something..... This will wipe your internal SD, OK so then install your rom and reboot.....

I am starting to think you flashed a non GE kernel and didnt realize it You just got to give the phone some love, thats all. It knows when your upset you know.
[T-Mobile Samsung Galaxy S 4] avelis26:
lol

The weirdness continues :P

sooo it started boot looping again. Then I rebooted to recovery (which obviously after flashing NB4, its no longer PhilZ) and did factory reset. Now its working again with latest firmware.

Also I flashed the GE rom from HERE in XDA and used it for like 2 or 3 months then it suddenly stopped working so I don't think the kernal was the issue... I'm so freaking confused :P
[T-Mobile Samsung Galaxy S 4] TigerDNA:
Flash something else, GE is boring, Flash something crazy like Slim or something, that might work... Possibly it could be a bootloader issue, did you ever get on the MK2? Maybe you got one of the female phones. Sammy made some by mistake. they can be real finicky every now and then, like they work just fine most of the time, but about once a month or so they just crap out. Could be that too.
[T-Mobile Samsung Galaxy S 4] avelis26:
No never got MK2... went straight to NB4

And I LIKE GE lol...

Well whatever happened it seems stable again now currently on stock NB4

Next thing to check is if the knox warranty flag is still tripped... Do you know how to do that ?
[T-Mobile Samsung Galaxy S 4] TigerDNA:
Yea your Knox flag is tripped alright, you have zero chance if ever getting back to 0x0.... Nobody knows how to do that brother.
[T-Mobile Samsung Galaxy S 4] Corwinder:
Just put the phone in download mode. Power off then volume up, home and power. You'll see it when you get into download mode.
[T-Mobile Samsung Galaxy S 4] bobolinko:
Philz's and TWRP both had small glitches on the GS4 4.2.2 Stock Rom.

I downloaded and installed the OUDHS-Recovery-jfltetmo-1.0.3.3.tar and have it all PERFECT now! You can search using exactly that filename and download it for your use. IT IS THE flashable Recovery Version.

I can, using Rom Manager, NAME THE BACKUP before booting into recovery, and it makes the backup just as I named it!

I can also recover using Rom Manager, and visually select what backup file I want to restore to, again, before booting into recovery!

CWM type backups take longer then TWRP backups to complete, but I have not had any instance that a backup I made couldn't be restored.

I did have that problem using "TWRP" and "On Line Backup". (No longer do I trust using those)

Hope this info helps your decision!

Good Luck and Aloha!
[Huawei Ascend P6, Mate] savudragosh2:
Hello guys

It is my first post so excuse my bad english.

I want to ask you if somewone used this aplication for trim suport.

In the aplication review sead that if the phone model is not compatible can brick the phone.

So is Ascend P6 compatible with this aplication or not?

On the other hand what type o memory module is used as system memory?

Thanks in advance for the answers.
[Huawei Ascend P6, Mate] tauio111:
I think it requires some sort of kernel support for TRIM, which the huawei kernel obviously doesn't have...
[Huawei Ascend P6, Mate] savudragosh2:
Thank you for the answer.

The other important question is: ascend p6 comes with eMMC technology or flash, for the system memory?

If we have eMMC (and we should have because it wase released in the second half of 2013) the Trim suport in kernel should be a must have; i think.

Thank you in advance for your answers.
[Huawei Ascend P6, Mate] tauio111:
Samsung KMVUS000LM-B304 252 chip is used for memory I believe, but I can't find any information of it being either eMMC or flash. I attatched a picture which has the word "Flash" in it, so it may actually be a flash memory. Nonetheless TRIM support came with 4.3, P6 launched with 4.2.2, and altough we have a 4.4.2 beta, the changes in the kernel have been very minimal. Unless they build a new kernel from scratch (which I doubt highly), the TRIM support wont be there. I also believe the K3V2oem1 kernel wont be updated much, so we have to rely on the K3V2+ kernel source, with some modifications, if it gets released and updated to a newer linux kernel version.
[Huawei Ascend P6, Mate] savudragosh2:
Hello and thank you again for the answers.

For what i can see in the picture the one in the middle is the memory card. It says SAMSUNG that means that it is a quality chip because for what i now samsung fabrics he's one memory chips. I will dig more hopping to gather more informations.

The main question remains: Has anyone used the softwere LAGFIX with ascend P6 without any problems?
[Huawei Ascend P6, Mate] savudragosh2:
I found this, maybe you can make more sense of it.
[Huawei Ascend P6, Mate] savudragosh2:
i found more about the chipset:
[Huawei Ascend P6, Mate] tauio111:
This seems interesting, it could aswell be an eMMC since it has ram inside the chip.

But something is wrong with the kernel of P6. Try Androbench and try taking the Micro test in there. I got only 20mb/s!!! (G2 and other devices get well over 110mb/s, hell, even the Galaxy S2 gets more than 2x faster rates!).

Highly possible that the chip needs TRIM, but unfortunately we have no way to enable it yet.
[Huawei Ascend P6, Mate] savudragosh2:
For what i read a eMMc can be trim in 2 ways

First with a build in system suport like JB 4.3 or KK

Second with a build app like LAGFIX manually.

I want to try thos app but i can brick the phone. I am in mutch doubt.

I am confused about there policy because what are whe traing to understend is normal for a bettter performance and a musthave of a healty system beased on this type of memory for storage.

Sorry again for the gramatical mistakes.
[Huawei Ascend P6, Mate] savudragosh2:
I found a clasification table on samsung website and the chip is in thr lower class 100 suitable for poor quality smartphones with dual core.

Maybe here is the reason for the poor performance despite the quad ore and 2gb off RAM.

If you have time please do a search on samsung website for the cip. It is a pdf presentation but it is large and i cant uploded.
[Huawei Ascend P6, Mate] savudragosh2:
specifications of the KMVUS000LM memory chip.

I found some specifications (marked with red). If we have some other chip specifications like S3 or nexus 4 (phone close to performance too ourse) then we can figure out if it is poor performane chip or it is a bad made kernel.

Hope that someone can figure it out.
[Huawei Ascend P6, Mate] savudragosh2:
I runned the LAGFIX aplication afterall. Unfortunelly doesn't work on our device, because of bad kernel suport or hardwere. I runned also ANDROBENCH: and got a sequential read/write 26.9Mb/s / 6.38Mb/s. VEEEEEEEEEEEERY LOW compared with other devices.

I AM VERY DISSAPOINTED ABOUT HUAWEI. Very good specs on paper but dissaponting components/kernel support in reality.
[Huawei Ascend P6, Mate] ZuperStyler:
When HUAWEI will release the source code you will be able to try any custom kernel, I'm sure someone will make one, there are a few already, but not so good due to HUAWEI's restriction.
[Huawei Ascend P6, Mate] savudragosh2:
Thank you for the answer.

Do you think it is a kernel issue or a slow performance memory card?
[Huawei Ascend P6, Mate] ZuperStyler:
Definitely a kernel issue
[Huawei Ascend P6, Mate] tauio111:
I also think that this is a kernel issue, appearantly their kernel includes tons of useless parts and tons of parts that dont work well.

But I dont think that a new kernel would make it much faster probably like ~50mb/s
[Huawei Ascend P6, Mate] savudragosh2:
Thank you for your asnwer,

I put a question in OMNIROM treath but no one answered. The question is: Has Omnirom (because in kitkat based) the suport of TRIM?

I asked you because i saw you use omnirom.
[Huawei Ascend P6, Mate] savudragosh2:
And another qiuestion: From what i saw huawei released the kernel source for B111. If it is such a bad kernel why did no one develope it?
[Huawei Ascend P6, Mate] tauio111:
It does not as I said before. We dont have the KitKat kernel source code yet.

surdu made a green kernel. We dont have any skilled kernel devs here + driver sourcecodes are still not released and probably wont be, without driver sourcecode, kernel version can't be updated and we will have to sit on 3.0.8 till the end, sadly.

I just tried Lux and it works great! $4.00 well spent!
[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] mrpeggit:
Lux is just part of the solution for me. The app has an excellent debug feature to watch the raw sensor data. Using this feature I can see that the sensor data itself has a problem.

Steps to reproduce:

- put tablet in direct sunlight or under a bright lamp

- start the debug readout of the brightness sensor

- cover the sensor by hand (sensor is situated top-right from the G in Samsung)

- observe the reading on the screen: it is something below 10.0 for me

- move the hand away from the screen very slowly but still covering the sensor from direct light: the sensor reading increases gradually to values around 100 to 200. It is easily possible to achieve any value up to here by just varying the position of the hand.

- when the sensor readout reaches a value above 250, I can observe a jump to values above 6000. There is no way to cover the sensor carefully to reach any value in between 250 and 6000. The readout just jumps between these two extremes.

- if you decrease the intensity of the ambient light (e.g. by turning down the sun...) you can achieve values as low as 1000 or 2000. But there is always this huge step bewteen 250 and the higher value.

I oberserved exactly the same behaviour with the stock ROM and with the CM ROM from crpalmer.

If there is a way to change the sensor readout, that would be great. I cannot imagine that it is an inherent property of the physical sensor. If so it is just badly engineered :(
[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] Weo:
I'll check out the Lux app, but thought I'd pipe in with my 2 cents (although its probably worth $0.00)...

I noticed sensitivity to shadows with Samsung's auto brightness on my S3 when using an Otterbox Commuter case. If the case cast a little shadow from the lip, the screen would go very dim in bright conditions. My Tab Pro 8.4 seems to have similar sensitivity issues with shadows. I often use the tablet at my desk, with a soft white ceiling light behind me and an overhead desk lamp turned off (unless I am doing paperwork). If the tablet's light sensor catches my shadow from the ceiling light without my overhead light on, the screen goes very dim. If I reposition it with the sensor outside of my shadow, it is perfect for me. It is an annoyance though. Once my Seidio case gets here, I wonder if it will be more of an issue.

I decided to give Kit Kat another try a few days ago, but since then I have not been able to connect to LTE.

Prior to flashing I was running CM10.2 and my LTE was working fine. I initially lost LTE when I flashed PACMAN. I have also tried AOSB/ProBAM and Beanstalk. None of the Kit Kat roms gave me LTE so I gave up and restored CM10.2, but afterward I was still not getting any LTE connection.

I tried flashing the MD4 modem, but that didn't seem to fix anything. I've also heard that going back to stock could help, but I'd rather not have Knox if I don't have to use it. Which stock ROM here on XDA would be the best (Not planning on using the ROM. I just want LTE and then will flash back to Kit Kat)? Would a different modem fix my LTE issues? Is MK3 better than MD4, or are there any newer modems I should try?

Thanks for the help!
[Sprint Samsung Galaxy S III] joeyhdownsouth:
Any of the ROMS that have [TW] in the title should work. Full Knox only comes with flashing a tar file in ODIN, because your flashing every partition of the phone. Modified stock ROM zips do not have knox, unless otherwise noted. Make sure to do a prl and profile update when you flash to stock.

Flashed Wicked Sensations last night with the MK3 modem and I seemed to be getting LTE as soon as that booted. Updated my PRL and Profile, and then wiped. Installed AOSB again, and I seemed to be getting LTE until I rebooted. After the first reboot I seem to be stuck in 3G again.

I think that's the opposite of what happened to me. My status bar said I had LTE when I first booted AOSB (this was after flashing/wiping TW). After the first reboot it connected to 3G and I haven't seen the LTE signal since.
