[Samsung Galaxy Nexus] teddy333:
My Verizon Galaxy Nexus was rebooting twice a day on its own and it was frustrating the hell out of me. I originally thought it had something to do with streaming especially since I noticed that it would happen most often when streaming via Google Play. Long story short is that I found the culprit to be the "Beautiful Widgets" app. It was especially apparent when I noticed that my phone would reboot when the app would update. It has now been two weeks since I uninstalled the app and I have not had a single reboot.

I hope this helps someone that may be having a reboot issue.
[Samsung Galaxy Nexus] thesoldier:
Did you have a lockscreen widget for beautiful widgets as well? That would be your problem.
[Samsung Galaxy Nexus] teddy333:
No, I did not have a lockscreen widget.
[Samsung Galaxy Nexus] thesoldier:
Hmm, the same thing was happening to me on my gnex until I removed the lockscreen widget...then it was fine.
[Samsung Galaxy Nexus] curley1441:
util I saw this thread i had reset my phone twice took the widget off no problems now thanks
[Samsung Galaxy Nexus] jocloud31:
I've been experiencing the same issue, but I do NOT have "Beautiful Widgets" or any similar homescreen/lockscreen modification app. If anyone has any information regarding what causes the problem, I'd greatly appreciate it. I also notice that it happens when streaming via Google Play Music, but it also happens other places, and sometimes when sitting idle with no user input or running apps (typically there are apps in the background history, though).

What is odd about these reboots is that it isn't a full reboot. Instead of shutting down and rebooting from the "Google" screen, it goes straight to the second part of the boot screen with the multi-colored X.

If this would be better suited for it's own thread, I'll happily move this. Thanks!
[Samsung Galaxy Nexus] Cilraaz:
If I'm not incorrect, that's a graphic engine restart, rather than a full reboot. It's the phone equivalent of your PC's graphic drivers crashing and recovering. Usually a logcat or last_kmsg will show what caused the restart.
[Samsung Galaxy Nexus] jocloud31:
I appreciate the information. If it is a graphic engine restart, should it be affecting the network as well? Both wifi and cell connections take a very long time to reconnect after these reboots, if they reconnect at all.
[Samsung Galaxy Nexus] Winesnob:
I've heard this also, but whenever this happens on mine a reboot is logged in the reboot logger app, and everything behaves as if a full reboot occurred - radios reconnect, Google wallet restarts, media scanner starts draining my battery, etc.
[Asus Transformer TF700] jake21:
So everyone (including me) has noticed that the transformer slows down when doing i/o. I originally thought this was a hardware issue (slow memory? slow bus?) but from various threads it sounds like third party os fix the issue. So I have two questions:

Can someone explain what the asus kernel does wrong (or how third party kernels) fix the issue ?

Why asus cannot copy the fixes from third party kernels into their kernel (I presume this is a kernel issue and not support software around the kernel but maybe that presumption is incorrect; maybe it is a driver issue or maybe there really is a hardware issue?)
[Asus Transformer TF700] _that:
Random write of small blocks to the internal eMMC is slow. Flash memory has huge erase blocks (typically a couple of megabytes) and large write blocks. Writing 4KB is a relatively slow process.

They can't fix it, they can only work around the issue by tweaking the kernel's caching parameters. Or, in the extreme case, disabling the fsync system call. Usually, an application calls fsync to ensure data has been written to the disk, so that even in case of a following crash or unexpected power loss the data on the medium is consistent. And normally fsync waits until the write command has completed. If you disable fsync, the app no longer has to wait, therefore no more lag. The data still resides in the RAM and is eventually written to the card by the background cache flush thread.

Downside of disabling fsync: If the tablet crashes in the wrong moment, you may in the worst case lose all your data, run into a bootloop, etc.
[Asus Transformer TF700] gordo2000:
If this is true, how come with original release ICS 4.0.3 everything runs smooth and fast. I installed latest Jelly Bean 4.1 and slow real bad, i downgraded back to ICS 4.03 and it is fast again. Is it a driver issue. It can't be hardware.

Thanks
[Asus Transformer TF700] jake21:
Ok I can understand the issue with fsync and small writes but then all tablets would have this issue (unless the infinity used particularly poor chioce of hardware). Also does this indicate if writes were disabled in (for example) browsers then they would be silky smooth ?

-

It would be nice if the tablet could mark certain directories as critical and flush those faster than other directories (perhaps abusing the meaning of the sticky bit on the directory). Certain non critical data can avoid having immediate flush (though if andriod apps are calling fsync explicitly there might be some stickyness in changing the behavior of the api). Anyways is my understanding correct that you are indicating that Asus used a particularly poor choice of eMMC or tweaked the kernel to flush more frequently ?
[Asus Transformer TF700] _that:
I didn't see a big performance difference between ICS and JB, even though JB should be even faster after all the "Project Butter" work. What is slow for you on JB?

---------- Post added at 07:35 PM ---------- Previous post was at 07:30 PM ----------

Many people said the TF700's eMMC is slower than good microSD cards, and that can be reproduced with benchmarks.

To check how the browser performs if it doesn't have to write to the eMMC, install Browser2RAM, which moves the browser cache to a ramdisk. In my experience, there is still lag on some pages - so not all slowdowns seem to be I/O-related. It would be interesting to find out the real cause of this.

There may be another I/O situation except random writes: large writes which block small reads from another process. HPI should help here, but I think the 3.1 kernel doesn't support it yet.
[Asus Transformer TF700] johnlgalt:
Agreed. However, even with Browser2Ram, I'm betting that there is still some i/o with the emmc that cannot be hijacked by broser2ram, and therein lies the problem. If nothing else, using RAM like that may force the tablet (b/c of screwy coding) to start paging data to...yup, you guessed it, emmc ... a lot sooner than it actually needs to.

Has anyone tried B2R along with dev settings to kill apps ASAP that are not in use? Perhaps this could lengthen the time before paging starts to occur?
[Asus Transformer TF700] gordo2000:
Overall, everything runs smooth on ICS 4.0.3. Browser, opening app, games, there is no hick ups when watching movies, that happen alot on JB 4.1.1. The whole OS is smoth redrawing. On JB, there is always a wait few seconds to open application folders or closing it. I did reformat to default but no help.
[Asus Transformer TF700] _that:
Not all I/O automatically leads to problems. The latest version of Browser2RAM only redirects the browser cache, it does not affect browser settings, bookmarks, etc. - which is usually a good thing.

No. Paging does not occur *to* the eMMC (no swap space is configured on the TF700), but only *from* the eMMC, to fetch pages of executable files. While it is true that the ramdisk for the cache uses some memory, it would only make a difference if you have lots of background apps competing for RAM.

A first step to see how much I/O happens is to watch the output of "iostat".
[Asus Transformer TF700] johnlgalt:
Thanks for the heads up. So, why does it still cause pauses and the like then?
[Asus Transformer TF700] _that:
Good question. It's time to find out. :)

Arm yourself with multiple adb shells and watch the output of iostat, top, free, or whatever else you can think of that displays interesting metrics. Then do something that causes lag and see if you notice a specific pattern.

(I am currently away from my main PC, and the SSD in my laptop decided yesterday it no longer wants to read ntkrnlpa.exe - so no adb for me right now)
[Asus Transformer TF700] johnlgalt:
I'll need a bit more specifics - I know adb well enough and can shell, but these other ... executables you're mentioning are new to me.

I'm on vacation in Hawaii, and have a Windows 7 based laptop that I can use, so I can do this no problem - but not today. About to go see some sights before going on a Lava Boat tour at 4 PM local, which means I'll be bushed when I get back - plus I'm fighting a nasty ear infection that aches something awful.

AFAIK, though, I have no real plans for tomorrow or Friday, so I can take some time and investigate.

Also, FWIW: I'm rooted but have not (yet) unlocked my bootloader - mainly b/c I purchased the 64 GB version of the tablet and it is a C50, so I'm hoping something 'breaks' enough for me to get a replacement (c70? C90 even? :))- and hoping even more that it is running something under ICS .30 so I can nvflash a backup and not have to worry about goofing things up when I *do* unlock the bootloader.
[Asus Transformer TF700] jake21:
iostat and top are standard unix utilities. They would only be useful if run on the phone so I must presume andriod has versions. A bit of 'googling' and htere appears to be a developer's kit that includes stuff like iostat. If hte switches are the norm then something like "iostat -x 2" will produce nice output of performance of each 'disk'. top is a tool that shows cpu usage.

-

I've not done any developing for andriod (maybe I should bite hte bullet?) so have never tried to use adb or similar but i've done a bit of system development on linux (though I very rarely muck with the kernel; i prefer to work one layer above the kernel).
[Asus Transformer TF700] _that:
If you haven't done it yet, install BusyBox on your TF700. Then just open one or more command windows on your PC, run adb shell in each, and run "iostat 1" in one window, "top" in another, and maybe also adb logcat in yet another window.

That gives you up-to-date statistics about I/O and processes which currently use CPU time. Then try to use your tablet normally, and when it lags, watch the output on your PC if you see a big number of writes or a process eating CPU.

But don't forget to enjoy your vacation. :)
[Asus Transformer TF700] johnlgalt:
Awesome. Busybox already installed here, so this should be easy enough.

And I never forget to enjoy ... anything. lol

Hey all,

I was in the market for a new MicroSD card and I had a question about hardware. The market for these cards seems pretty wide, with multiple class cards as well as different standards, such as UHS 1 or 2, and so on. My real question is how do I find what my phone can handle as far as the UHS standards specify or what I can expect in terms of speed difference--and how to improve it.

And I have an Evo 4g, obviously, lol.
[EVO 4G Q&A, Help & Troubleshooting] Diablo67:
I'm using sandisk 32GB class 10,that seems to be fairly fast and with no lags,you might get lagging issues with Ultra High Speed sd cards,if the phone cant handle it.
[EVO 4G Q&A, Help & Troubleshooting] CNexus:
I have the same as Diablo, my write speeds are about 11.7 Mb/s and read speeds are about 14.7 Mb/s

I would say its a good card too, but it also depends on how extensively you use it, if you don't use it often then getting a lower class and/or size won't make much of a difference

[EVO 4G Q&A, Help & Troubleshooting] brianvillage:
I run a 32gig SanDisk class 4 I love it never had a problem. I burned up a class 2 32 gig in a week of use. On another note, I have heard that class 4 matches the phones performance levels. Like even though it isn't the highest class you can get, it's the best you can get because it matches up with the phone the best. But I have also heard class 6 is great for it too.

I am getting this phone in the next day or two and I have a few quick questions...

Has anyone started compiling CM10? If so what issues are you running into...

I haven't looked at the nexus 4 components to see what differs, but aside from modem is everything else identical?

I see some dev work in progress so hopefully I can get a few more custom rom options out there. I have only ever worked with Samsung devices but shouldn't be too different.
[AT&T LG Optimus G] Shelnutt2:
To some things up, the only major issue is the kernel. We needed to backport the gpu drivers, which we pulled from d2, since they already backported from 3.4 to 3.0. It's just a matter of getting it to boot now, we've made minor progress, but the holidays are slowing things down. Once we get the gpu drivers straightened out everything else will fall in place.

Hello,

I used rom toolbox to lower LCD density from 240 to 190, as a result I got much more usable space on phone because all the icons are smaller and much more content can fit on screen while everything is still readable.

There can be some bugs that have to be fixed by custom launchers so heres my setup:

-Official ICS V30a rooted rom

-apex launcher

-grid size set to one higher than stock

-rom toolbox pro (free version works as well)

-(UPDATE 1) widgetlocker for lockscreen

Only bug that apears with this setup is on a lockscreen, transparen gradiant is small, visible and ugly but Im gonna fix that with custom lockscreen and update you on that.

Have you ever tried this? Whats your experience?

Heres how to do this:

ROOT REQUIERED!

Get rom toolbox, go to performance, click build.prop, click file icon upper left in top action bar and you will see LCD density. Set it to 190, reboot. Then play arround with launcher to make it look good.

UPDATE 1: I used widgetlocker to configure lockscreen and that completes the setup.

Hi all,

I've been looking for software to stream live video from my WM6 device. I'd like to use my old Samsung i600 as a IP camera, if possible.

Who knows of any software to stream video from the i600 which can be viewed in a browser?

I think I used Qik some years ago, but I'm not able to find the right WM version of the QIK software.

I found TinyCam two post below, but it doesn't work well on " no touch screen" i600

Thanks in advance.

[Samsung Galaxy Nexus] Notn4:
So I got 4.1 running on my Gnex (EaglesBlood) and it has been working just fine as long as I remember. Now all of the sudden I'm not able to call my girlfriend anymore, she can call me and I can text her. We also tried switching phones and with my sim card in her phone I was able to call her and with her sim card in my Gnex she was able to call me.

So it doesn't look like its the sim cards or my carriers fault, but it still doesn't make any sense why my gnex refuses to dial just one number, all other work fine, it's just that one number that I cant call, it just starts to beep rapidly.

So far I tried the following:

Calling the same number from another phone with my sim [WORKS]

Deleting all contact info to that number [DIDN'T HELP]

Downloaded another dialer from play store [DIDN'T HELP]

Removed battery and restarted phone [DIDN'T HELP]

Clearing app data for Phone.apk [DIDN'T HELP]

I don't want to reflash the ROM since it's so outdated and I'm just waiting for a more stable release of PA, but there has to be something that can be done, it's just stupid that there is that one number that I can't call and it happens to be the most used one too :(

[Verizon Samsung Galaxy Note II] imablackhat:
also forgot to mention stock unrooted locked, etc, just high ram hog. sometimes randomly when i end all tasks i can get it to go down to like 600-800mb usage. but lately no matter how many times you end it, its at like 1gb, and it sucks because phones 1.75gb ram, and when i open a few things it starts to get really slow because theres not much free to play with.
[Verizon Samsung Galaxy Note II] droidstyle:
what does it matter? you have 1.75gb available and your using 1.11 so it leave you with 640mb free... No matter if there is 1gb free or 640mb you wont be able to tell the difference performance wise since you have more than enough ram to cover it. If you want about bunch of extra ram just laying around not being used then try a aosp rom, but you will lose all the fancy touchwiz features.
