Leave wifi off over night and check in the morning. It's a known issue with these magnetic cases. Google is going to have to push an update that fixes this issue. I actually received an email from the blurex case people detailing this. The bluetooth trick has worked for me very well. I have wifi turning off when the device sleeps and havent had an issue yet.

I tested with cifsmanager and it indeed was not working. It's fixed now, and I also added exFAT filesystem support.

Download:

ElementalX-flo-1.3

Changes:

-enable loadable kernel module support

-add exfat support

-fix cifs support

Tried out V1.2 tonight but noticed that using fiops I/O scheduler doesn't doesn't improve read/write speeds even when raising the buffer size to 2048. With Faux kernel, this scheduler gets over 150mb/s sequential write speeds while now I get around 20mb/s. Is that normal?

anyone on elemX1.2 and can mount an external 2.5 HD? im having trouble, i cannot mount any, even if it has external power on its own

i can easily mount any USB pen drive in NTFS or fat32, but i cannot mount a 2.5inch HD, i can mount a 3.5 external HD powered by adapter too

weird

im using USB OTG helper app to auto mount

i don't think stickmount works too good

I don't have an external HD to try, but all my USB sticks and my usb sdcard adapter mount fine. I'm using stickmount and I've tried mounting fat, exfat and ntfs drives, all working on latest version. Could be something to do with the power.

Can you attach the HD and immediately after send me the output of dmesg?

Would someone explain the "LED control"? I've never seen it before, as this is my first Qcom device. :P
[Nexus 7 (2013) Original Android Development] Ronde90:
On a rooted device led control let's you control the color, intensity, and flash duration and pattern of the led; It allows you to change the color of the led and pattern based upon whatever notification is received, meaning you can make it app specific. The nexus 7 fhd of has one color for the led so it isn't fully customizable on our device. Hope that helps a bit!
[Nexus 7 (2013) Original Android Development] natezire71:
I mean through the kernel. It has settings like "heartbeat" and stuff. How is this different from Lightflow then?
[Nexus 7 (2013) Original Android Development] Ronde90:
How are you getting to that setting? What App are you using and what rom are you on?
[Nexus 7 (2013) Original Android Development] natezire71:
Er, I'm using this kernel. TricksterMod Pro. It's on the "Specific" page. LED Control. There are settings for "lcd-backlight" and "white". No clue what they do though.
[Nexus 7 (2013) Original Android Development] Ronde90:
I've never really used trickster mod but my guess would be lcd back light controls brightness, lux, and adaptive sensitivity for screen brightness as white may control just the led. Idk. Your best bet would be to just play around and see what happens! That's what I always do. Sorry I can't be of more help!
[Nexus 7 (2013) Original Android Development] tni.andro:
I think what you are seeing is that in deep sleep mode, touches are not processed. Touching the screen will wake the CPU from deep sleep, but you loose the first tap from a double tap (a triple tap will work). If the CPU is not in deep sleep, the double tap works.

I've done some power consumption measurements. Deep sleep (display off) power consumption is 200mW (doubletap2wake off) vs. 256mW (doubletap2wake on). With the 15Wh battery, that makes 75h vs. 59h deep sleep until the battery is drained.

I asked this a day or two ago, but it probably got lost in the crowd. I'm on the latest version of ElementalX and noticed that changing the

I/O scheduler doesn't make any difference in performance. I've attached a few screenshots of AndroBench benchmarks on sio, fiops and cfq respectively.

I know that with fiops set in Faux kernel, the sequential write speed are around 150mb/s. They're nowhere near that here. Is that at all normal?
[Nexus 7 (2013) Original Android Development] tni.andro:
He has disabled fsync, so measurements on his kernel don't reflect flash write speeds at all (the written stuff is sitting in the memory cache and not on disk).
[Nexus 7 (2013) Original Android Development] bounti:
Oh I see. So there's no way to test the improvements being made?
[Nexus 7 (2013) Original Android Development] yellowdie:
I didn't have any issues from beta 0.2 through 1.1, but 1.2 and 1.3 have given me the first trouble with the occasional magnet not working crap, screen not responding, and random reboots. Nothing too consistent or crazy, just a few things here and there--definitely something I can live with. But this was the first time I was able to pull a last_kmsg (the other times it never gave me one). Shows a kernel panic so I don't know if this will help with anything or not, but here it is.

For the record: ultra bus OC, max 1.5Ghz, undervolted to 850, GPU at 400, cpu is interactive/fiops and gpu is Simple.

Don't know if I've posted this recently, but good work, flar. I've been enjoying your kernel since the N7.2 came out. :)

Edit: Oh! Last post in the triple digits! ;)

Edit2: First time it's done multiple reboots within a few hours. Here's a second kmsg if you need it. I just reflashed 1.3 and set the bus OC to elementalx (I know I could have edited the conf file, but I wanted tot reflash it anyways). So 1.3 is installed with all stock settings except thermal is set for cool.

I've been having random reboots a few times a day over the past few days as well, not sure how to post files through Tapatalk, but I also have some last_kmesg saved as well if you'd like me to email them to you.

[Nexus 7 (2013) Original Android Development] Cruiserdude:
Just got yet another reboot while the tablet was asleep, didn't notice it in time to get a last_kmesg. Anyone else having this many? Thinking about going back to 1.2 and seeing how that does, otherwise I may have to give something else a shot.

This is on a completely stock odex rom, didn't even flash it at all, this is directly from the factory image and just flashed the kernel.
[Nexus 7 (2013) Original Android Development] flar2:
About reboots:

The last_kmsg file will be there after a reboot until the next time you reboot. For example, if it randomly reboots, once it starts up again you can grab last_kmsg anytime until you reboot again.

[MENTION=4110932]yellowdie[/MENTION], Thanks for the logs, but I can't see anything in them, they seem incomplete.

If reboots happen while the device is idle, it's usually due to undervolting. Make sure you don't select the default in the installer. The default option undervolts your tablet.

Aside from that, if you have reboots, I highly suggest doing a full wipe and reinstall to rule out other things.

I don't make radical changes to the code. In other words, there is nothing in the kernel code that should be causing problems. Make sure all voltages and frequencies are stock. I haven't made any serious changes since version 1.1 when I added the Google updates.

I've never had a single reboot with my n7. If reboots were widespread, I think there would be more reports, since version 1.3 has over 2300 downloads over the weekend.
[Nexus 7 (2013) Original Android Development] yellowdie:
I agree--widespread is usually widespread. I had been UVing to around 800 for awhile with no issues, but lately I upped it to 850 (default in the installer); so I didn't think it was what my device could handle, but I'll bump it to stock voltages and see how it fares. I had heard some people mention reboots, but no logs. So I figured I'd chime some in--bummer they didn't show anything.
[Nexus 7 (2013) Original Android Development] flar2:
This is interesting, I will play with this a bit next weekend.

I'm thinking about doing this, even though my kernels can be set up completely in aroma. People ask for this all the time but I'm so busy trying to update all my kernels I never have a chance to get started. My wife keeps bugging me to do it and charge $2, because right now I spend a whole lot of time developing and don't make any money (except for a few donations, which are highly appreciated). I actually lose money with this hobby because I constantly lust after the latest and greatest devices.
[Nexus 7 (2013) Original Android Development] bounti:
Does anyine have any stability issues undervolting at 1.7ghz? I'd like to set it in the Aroma installer but would like to see if all works well with everyone else first. :P
[Nexus 7 (2013) Original Android Development] blazk:

[Nexus 7 (2013) Original Android Development] JCon0320:
I flashed this kernel on pacman rom and I'm curious as to how you guys did with it. In my experience, going above 1998mhz causes everything to fc on boot rendering the tablet unusable. I would like to know if this is something that is common for our service, a well as if this is more of a ROM issue. Thanks guys.

My setup :

1998 mhz max

825 undervolt

Gpu OC, on demand

S2w, usb fastcharge, ntfs
[Nexus 7 (2013) Original Android Development] RedDevils88:
I found out sometimes the tablet lags a while while I just turn it on. Is this kernel related? Anyone had experienced this before?
[Nexus 7 (2013) Original Android Development] z31s1g:
No. All it does is to trick the tablet into charging with the same current when connected to a USB port as it would on an AC charger (provided the USB port is capable of delivering). So with fast charge turned on, the device will at best charge as fast as connected to an AC charger, hence no damage to the battery.

---------- Post added at 11:03 AM ---------- Previous post was at 10:50 AM ----------

25% OC und UV? If the setup you posted is running stable you're lucky already, I can't push mine that far. It's got nothing to do with rom or device, you've simply reached the max OC/UV setting your processor can handle.
[Nexus 7 (2013) Original Android Development] Philaphlous:
Sorry form the dumb question again but what do I use to view my error log where I have a random reboot? Where is that file located? I feel like I have to hook my tablet up to my PC and view like a txt file that will tell me right?

Had a random reboot lastnight. Redownloaded the 1.3 kernel and reflashed it at 1.73ghz this time with nothing else different. I'll report back if I get another reboot. Stock ROM BTW.
[Nexus 7 (2013) Original Android Development] airmaxx23:
It's located in the proc folder, you want to grab the last_kmsg file.

So what kinds of temperatures are people seeing during heavy CPU usage (gaming)? I'm just curious as to how much warmer these run when compared to the original N7.

Hi. I've been using the kernel since I dot my Nexus 7 and have been loving it. I always play around with the settings and am curious to see what everyone's set up and what their experiences have been. This is mine:

Underclocked to 850

Min frequency 325

Max frequency 1425

Elementx l2 cache

Cpu gov. : intellidemand

Gpu gov. : ondemand

I/O: noop

Read ahead buffer set to 2256

I get roughly 2 days of battery life, a little less if I play real racing 3 a lot since it is graphics intensive. I find that everything is extremely fluid and never lags. I also use it for class everyday to read slides and books and aid in taking notes.

Also, I run deep sleep battery saver so that when the screen goes off it goes to deep sleep to save power. I find though that WiFi seems to run constantly so not sure if that is a 4.3 issue or a setting I have. Idk. Anyway, thanks for the great work!
[Nexus 7 (2013) Original Android Development] NekroWolfen:
The screen keeps freezing from time to time when I use this kernel on Carbon :(

Sometimes for 3 or 8 seconds, it doesn't happen with the kernel that comes with Carbon, I've been testing this for days now. All settings stock, no OC on anything no undervolting all stock, it happens with both Bulletproof and ElementalX, could be the touch2wake feature?

The last test I did was right now, after a full restoring to stock the nexus and installed the latest twrp and a clean install Carbon, still the same results. I miss the touch2wake feature :(
[Nexus 7 (2013) Original Android Development] flar2:
turn sweep2wake and doubletap2wake off and try it. If the problem goes away, then that's probably the cause. The bad news is I'm not sure if I can fix it because I don't really know why that would happen. It doesn't happen on mine.
[Nexus 7 (2013) Original Android Development] flar2:
Added some tweaks to speed up i/o.

fsync can be enabled/disabled. If you have a stable system, it is completely safe to disable fsync. If your tablet is prone to reboots or crashes, I recommend leaving fsync enabled. There is a slight risk of data loss if your tablet crashes before the filesystem is synced.

CIFS support was still broken because the the init.rc line it needed was not in the right place. I fixed this but you may need to dirty flash your ROM to get a fresh boot.img for it to work. So, if CIFS Manager doesn't mount, you need to dirty flash your ROM, then reinstall ElementalX.

I took a quick look at the OTG+charging thing, and it looks like it can be done, but it will take a bit of time. Something like that needs some thorough testing.

Download:

ElementalX-flo-1.4

Changes:

-add option to enable/disable fsync

-AIO: Don't plug the I/O queue in do_io_submit()

-add fstrim to init script

-update installer

[Nexus 7 (2013) Original Android Development] flar2:
Let's see how this works, I changed the installer to use the ramdisk from the ROM. If you're on stock, the settings won't stick because it doesn't have init.d support. This goes for any ROM you use, but I hope most of them have init.d support in their ramdisks.

I focused on performance options for this release: added overclocking up to 2214MHz, fixed automatic undervolting (be careful!), and added GPU overclock to 487MHz. This one has three "CPU optimization levels". "Stock" has stock l2 and bus bandwidth, "elementalx" overclocks l2 frequency, and "ultra" overclocks l2 frequency and bus bandwidth.

If you're one of the people who downloaded this before I posted this, re-download it.

Download:

ElementalX-flo-0.3 *BETA*

Changes:

-add CPU optimization levels

-add more overclocking options

-fix automatic undervolting

-option to overclock GPU (487MHz)

-update ARM topology

-add cpu_power driver

-use ramdisk from ROM

-update installer

-adjust doubletap2wake
