[HELP] F4 Phantom Kernel Oddity - TouchPad General

I had a strange problem. I just happened to open preware just to poke around today a few minutes ago and saw the phantom kernel and got excited and uninstalled my other kernel and rebooted to install this one. All went well for the first install. then as i was browsing preware it refreshed and i saw there was a kernel update, so i hit update. after it rebooted, i cant seem to enable or disable wifi. if i uninstall the kernel its fine, but if i reinstall it, the same problem comes back its really weird. any ideas?

I am having the exact same issue. I took the same path as well upgrading F4. Hopefully WI comes out with another update to fix this.
A reboot allows you to re-enabled wifi, but this is a poor work around.
F15C will do until the bug is fixed.

That is why you wait until it goes out of beta.

What's the fun in that? Anywho, sucks that the kernel doesn't dig your wifi. Been running it all day at 1.8 rather stably, with battery actually doing fairly well.

I think you're on the wrong forum there dude. It says developers in the url - beta is where we live.
I hadn't noticed the WiFi oddity but tried it and sure enough. The prior F15 kernels had WiFi problems for me so I stopped using them. Seems that unixpsycho doesn't think much of people using WiFi.
Did you guys try the 1.8+ GHz speeds? My pad crashed at that speed - had to learn how to reboot using the hard buttons lol.

I have had mine lose WiFi 2x already and was unable to turn it back on w/o reboot

there'a an update 3.0.2-46. Did that helped?

My touchpad is completely stable using F4 at 1.8
Browsermark for me has resulted in scores around 38k with conservative governor, 54k with ondemand, and 74k with performance.
Battery drain seems to be only slightly worse than on F15c despite having both cores running at all times.

I tried the F4 Phantom recently and while it seemed promising at first, the second CPU always showed as N/A after I would wake it from sleep. I've tried uninstalling, going back to default settings, and reinstalling F4 and had these same results. I'm running warthog now and I don't experience the 'N/A' anymore and running stable so far.
Anyone else get the 'N/A' using the latest F4 Kernel (3.0.2-46)? Btw, I've been using it at 1.7Ghz.

I gave F4 a try. Also got wifi problem after a few hrs. Going back to warthog.

I don't have any problem with it. My WIFI works fine.

I upgraded from f15 this evening. Its noticeably faster on f4 with both cores running. Govnah suggests the battery is doing fine but I've lost about 5% in the last 30mins just browsing XDA... Doesn't sound quite right?
Wireless has been absolutely fine too.
edit: hour and a half later and govnah is showing 2nd core as N/A. Reinstalled but getting the same thing. Tablet seems just as fast though which is odd.

I have the same problem with F4 with all the profiles I saved, the second core says N/A. It did show the second core running when I installed it last night. I tried the 1.8, seems faster, but rebooted everytime when while loading sims social on facebook lol.
Edit: Weird thing, I did a device restart, and now the second core is showing. However, the device start didn't work this morning.

Same here. After about 30mins, my 2nd core shows as N/A. I do agree it does seem to keep its speed. Maybe its something with govnah?

I highly doubt it has anything to do with govnah. It is the kernel causing the issue. Have been running the earthly kernel and have had no issues at 1.7.

after latest update I have had NO problems

[Q] Why is my phone rebooting at the unlock screen?

OK, so I'm on GSB 3.4 (though this issue began with 3.3), and I'm having a problem with my phone rebooting (screen cuts off after about a second, and the phone immediately reboots to the skateboard screen) at the following times:
1. Whenever I attempt to wake the phone from sleep.
2. Whenever I hang up a phone call.
3. Whenever I get a phone call while the phone is asleep.
4. Whenever I plug the phone in to charge while the phone is asleep (be it a wall socket or PC) [see below].
These problems only occur when the phone is NOT plugged into a charging source; the problem appears to be nonexistent in this scenario. But as soon as I unplug, all 4 become auto-crash scenarios.
I tried going back to GSB 3.2, but no dice. I then resorted to the stock-ish XTRsense ROM, which fixed the issue, but going back to Froyo just was too big a downgrade for me.
Throughout this process, I full-wiped multiple times, hoping to track the issue to an app or setting, but even before restoring anything through TBU (I think I may have just let the phone go to sleep at the "Touch the Android" initial setup screen once), the problem persisted, eliminating apps, settings, or CM7 CPU modifications as possible culprits.
I've continued to play with CM7 CPU settings even up till now, but I'm not getting much of anywhere. I've now resorted to the "Caffeine" app, which just never lets the phone go to sleep, and I just turn the brightness down or activate the "Desk Clock" mode in the default Clock app to save battery.
HELP?
Have you tried Tazz's ROM or CondemnedSoul's ROM, just to see what happens with those? CS's ROM uses ADW as the default launcher (not sure about Tazz's) - perhaps it's something with LauncherPro?

Guys, just thought I throw out the idea that it might an overclocking (i.e., hardware) issue?
I see that the Conap's CFS kernel that GSB 3.4 uses is max clocked at 604 MHz, but maybe that's too high for your particular phone?
I also think that schultzmd's comment about the ondemand governor helping might point to the clock stepping to a higher speed when coming out of sleep (and being related to clock speed). Maybe try running the phone at a lower speed just to see if its better behaved might prove instructive.
Just a thought...
Cheers!

Sounds familiar: http://forum.xda-developers.com/showpost.php?p=14016867&postcount=5186
I'll try the changing the max, but I know I've tried as low as 604 max (19 min) with the problem persisting, and as high as 710 or 768 before GSB 3.3 (when the problem started) with no major issues. And I had already been using Ondemand when the problem started, having stopped using Smartass when I thought it slowing the performance down a bit. Any other governors I should try?
And does the overclocking issue not apply when a phone is charging?

Well, you are introducing some extra heat into the equation while charging, which might be enough to tip the balance against you if it is indeed an overclock issue.

You would have only seen that if you had seen the post in the GSB thread, of course.
I am still going to suggest trying Tazz or Condemned. From what the OP says, he should be able to see that it's having the same issue pretty quickly.
But, just to rule out the OC issue, you could try setting the max to stock 528 and see if it still happens.

How about on Tazz or Condemned? And, 19.2 is too slow for a minimum for this kernel. 245 should be the minimum.

I was inquiring as to why the issue DOESN'T happen when I'm charging. I'm not sure if that's what you were saying, but I have no issues while the phone is charging; it's weird, because CM7's CPU governor doesn't allow profiles for "screen-off", "charging", or anything like that. It just seems to make my problem more random and untraceable. It literally is happening on EVERY CPU setting, even 480 max (which to me, is just pointless to actually use)
I've full-wiped so many times in the last few days, I'm wary to just try a different Gingerbread ROM when GSB is (was, for me) so stable and full-featured. I'm trying my darnedest to just stick it out and charge-charge-charge to avoid the issue.
One more thing: if, right after the phone reboots itself, I unlock it before the screen goes off and manually put it to sleep and quickly wake it back up, the issue usually doesn't occur (and I can keep doing this, putting it to sleep and waking it back up again, with no issue). But if I unlock it and let it sit and reach the screen timeout itself (or never unlock it after it reboots, then let it sit for a while), the problem reoccurs.

I have used both GSB and Condemned and you will not be missing anything. I stopped using GSB because I could not get market updates to stick reliably. I do not have that issue at all with Condemned.
Right now the only issue with the latest Condemned is apparently a GPS issue, so I would go with V6 or V7 rather than V8 for now until CondemnedSoul gets an update. Or, if you don't navigate, go ahead with V8. It's just fine.
You're obviously having a stability issue with GSB now, so you have nothing to lose but about 45 minutes of time and a Nandroid Restore to go back to GSB if you don't like it.
So, I had a minor issue that was fixed by switching to a different ROM. It's worth a try.
I wish you luck finding a solution.

Nate,
Sorry about that ...I was confused from where you asked in post #8 about whether or not overclocking was in effect while charging (it can/could be, depending on the overclocking monitor/govenor I suppose) and I had lost that point from your original post.
I would say take doogald's advice and switch to at least some other ROM since that would help indicate if it is indeed a software issue or a hardware issue. Its sounding like its not clock-speed related given the things you've already tried. If you've still got issues on other ROMs, that would tend to point to some hardware issue (our Erii are getting a little long in the tooth at this point, after all).
You could even flash back to stock and see if the phone is still stable there since you can always re-root and re-restore your Nandroid backups.
Good luck...I hope you figure something out.
Problem is alive and well on Condemned GB. *sigh*
XTRsense was fine and flawless, but going back to Froyo after months on gingerbread was just too depressing for me...

I'm going to make one more suggestion - not sure if you have tried this yet, but try flashing GSB from a full wipe. When you go through the setup, DO NOT LOG IN TO YOUR GOOGLE ACCOUNT. After the launcher starts, go into the market, let it log you in to your Google account then, and then install all of your apps and change all of your settings from scratch.
When you log in with your Google account when installing a CM ROM, it tries to restore your apps and settings from your last CM ROM install. It may be that you have some weird setting or app that is causing this that you just keep reinstalling when you flash the ROM and log in with your account.
If you've already tried this, then try running xtrSENSE or xtrROM instead. They are both excellent ROMs and clearly your phone likes them better.
[edit] Oh, and try leaving your min at 245 MHz for a while. See if that helps your phone run better. It should, and it should have the exact same battery life as 19.2, as nonsensical as that sounds.
It is literally happening as soon as I boot the phone after a fresh GB install. I four-corner the Android setup screen, let the screen time out, and boom I'm screwed.

[Q] Underclocking messes up touchscreen behavior

(summarized below in tl;dr version)
Since my problem I need help with showed up after going back to stock + root, I thought I'd ask in general before filling up the ROM discussion in development about the problem that I found after updating to ICS (leaked).
Had an odd problem crop up on me with scrosler's CleanROM 2.2 SP1 running (will 'splain in a sec, and tl;dr sum-up at the end), so I relocked, flashed back to pre-OTA official firmware and then let the OTA run. All was good, and I was happy. I unlocked again, installed Amon Ra, reinstalled SU, and started putting in my happy-fun root required tools (Oh Titanium, I likes you so). Then, my problem reappeared.
So my problem is occasionally the touchscreen would act "wacky" at times. Specifically, while in my browser, sometimes when I tried to scroll while browsing, the display would act like I was using pinch-zoom. It acted like I was touching the top left corner of the display in portrait mode, and zoom-in/-out according to how I was moving my touch that I intended to scroll. Then I noticed that games which required multi-touch had significant problems reading constant touch on most of the top-half of the display (left half in landscape mode with the carrier name on the left). I like Age of Zombies, and while the game would start off running right, within 20-60 seconds, the movement virtual controller would rapidly turn on and off, leaving me able to fire but not move. Grand Theft Auto was unplayable, as every time I touched a direction key in driving mode, the system would lose track of my holding the gas.
Troubleshooting took a while, as I had installed a lot of apps, and made a few changes at once after everything appeared to run properly. Ultimately, the problem appears to be caused by underclocking, and I can't figure out how to kill that and lock myself at stock speed. Haven't tried an overclocking capable kernel to see if they run any better, and haven't tried checking voltages to see if bumping them on underclocks would fix it.
I have used Antutu CPU master, an old version of SetCPU, and System Tuner Pro (from 3c). I can set the min and max CPU to 1.52, and it seems to stay for a while, but eventually, the setting reverts to allowing underclocking and my touchscreen gets goofy.
tl;dr: My system, even after restoring to RUU/OTA, wants to underclock. When the CPU runs under stock speed, my touch-screen misbehaves, particularly in gaming, but also in browsing. Any help?
Thanks
Can almost definitely confirm it's just bad hardware at this point.
After running 2 days without problem other than the touch-screen issue noted above, the phone entered an persistent bootloop after I loaded Juice Defender today. Phone would reboot, come up to home screen, get a data connection, tell me how many new email and texts I had, then tell me an app (same every reboot) was not responding and reboot 2-3 seconds after I cleared the error. Even when I managed to get to market before a reboot and uninstall the last 2 apps I'd installed, the phone is still in a boot loop.
Appreciate all that took the time to read, and wanted to share that there's a pretty good reason no one could respond with a solution.
Well, it probably is bad hardware but two cardinal rules I have when working on any Rezound is NEVER restore with Titanium BU & don't use Juice Defender (and I have a paid version of it).
I have had both mess up certain phones & I do this stuff all day at work.
I only noticed the underclocking issue with the ICS roms. But, I believe it is due to the Kernels not supporting under/overclocking and scaling options yet.

I've had the same issue for a while now and nobody answered Me either. After a little research it seems we have bad digitizers. I say this because that was happening to me on gingerbread and I upgraded to ice in part to fix it.

Okay so I have a similar problem.
I have hephappy cm9 prefinal installed just started having problems with rom. screen was acting funny so I turned on the touch point developer tool supplied with the rom. I have found that I have multiple touch points when scrolling with one finger.
So I used a apk called touch recalibrate that I got when I was on mik's cm7.
Which I have recalibrated aprox 7 times with no improvements so I set my cpu to min 600 max 600 smartassv2 this did not help either. If anyone has the answer to this problem please let me know.

[Q] Maybe a potential fix for SOD(sleep of death)?!?!

Hi Guys,
Im no Genius when it comes to android, but I have done my fair share of programming before, but my SOD are killing me and a last resort is a warranty exchange as I cannot be without a phone.
So far I have been getting SOD about 5 times a day if not more, and I am one for tinkering with gadgets until i break or crash it, fix it and doing it all over again.
But anyway back on topic
I have noticed this in the build.prop
" persist.ril.mux.sleep=2 "
And so I wondered if this is causing my SOD, does anyone have any ideas regarding its uses?
Findings (as of 2155)
In my testing thus far I have changed it to "persist.ril.mux.sleep=1" using phone leaving it for an hour doing it over just for fun, And I have been SOD for 5 hours straight and haven't had any SOD or adverse battery drain
I mean this may not be the cause of the SOD for me, or anybody but I am up for trying just about anything
What is SOD?

Sorry, Sleep Of Death
I have SOD here too. To me it's only happens when I turned off a data connection (3G or wifi).
I use LoadMonitor app as a workaround for a while, with success.
At now I'm using Neutrino 2.5 CM7 ROM with success too. I think it's more a blur rom problem than cm7 one.
Let us know about your progress.
So if you disable load manager you would get SOD?
I am making a script to update a few things so far no SOD for me, after a few tweaks
What settings are you using on load manager ?
Any info you can give me will help in me tracking down some of the errors and temporary fixes people are using to avoid the dreaded issue
Oh, THAT's what that was!
I forgot to turn the wifi back on a few nights ago when I said "Hey, let's watch some movies on netflix with my super-duper mirroring-abled phone!" So an hour into it, LBE Privacy warns me I'm about to max out my data, and I go turn the damn wifi back on but turned OFF the 3G.
Then last night I go to wake up my phone and the screen is "black but on", & took a couple of tries to wake it. I'm on Nottachtrix.

I'm a bit confused here. I don't know what "load manager" is.
What a sad is I used LoadMonitor app (from market) as a workaround.
LoadMonitor just monitor taks that are running in your device. But it have an option that claims to prevent device deep sleep. So, when I checked this option my device don't get SOD.
It's a workaround, as I sad, and I don't know how LoadMonitor do that.
What is load manager?
Thanks

I tried some roms and the only one I hadn't random reboots was jokersax11 alpha7 (ICI), now I'm on beta 0.2.0 and had reboots.
I'm having the same problem. I've tried 3 different ROMs. I used Nottachtrix, following the directions to the letter with reboots and hard locks. Recently I flashed back to 4.5.91 (w/pudding) and I was having the same issues. I noticed that on the hard locks, my phone appeared to be warm, so I used SetCPU at 216MHz and still had hard locks and random reboots. I've not set the lowest setting at 301 and so far I haven't had any reboots, but its only been about 5 hours. But I was having them at least once every few hours.
BTW - I also noticed that I only had the freezes and hard locks when the phone was running on the battery. I rarely had problems when the phone was on the dock or USB charger, however, I did have reboots when it was on the wall charger.
Another program you can try is call 'Wake Lock' available from the marketplace. I haven't used it yet, I'm still experimenting with load monitor.
Wake lock has a few different options and has some really good review.
I confirmed that Neutrino 2.5 CM7 Rom works great without reboots.
That's a patch you need to apply to correct a battery drain problem of the original version. Notorious544d are working in a 2.6 version including that patch.
To me it's working like a charm. I'm testing for two days but, of course, everyone needs to test it in your own device.

Atrix SOD & Random reboots related to Wifi?
Does anyone know if the Atrix SOD & Random reboots are related to WiFi. I've had my wifi off all day and I've had no crashes.
I'm going to run it for a few more days without Wifi and see what happens.
I don't know about other guys, but wifi and 3G was the cause of my Atrix SOD and reboot problems.
Solved it using Neutrino Rom CM7 based.
See you!
Still working on my SOD issue, but recently, I disabled most power options, turned off wifi, rebooted and I've been running for 2 days with no crashes. After day 3, I'm going to turn wifi back on reboot and see what happens.
Update 1
After 3 days with wifi disabled, I've had no crashes, no freezes or random reboots. I'm going to enable wifi again and see what happens.
Update 2
After turning enabling my wifi and using it briefly then turning it back off, I had a random reboot later that evening.
The more I used my wifi, the more frequent my crashes became.
Interesting side note
I can enable all my radios when plugged into the desktop charger and I won't experience any crashes, however, if plugged into to the AC charger, I've had reboots and freezes.

[Q] Why does my Tab keep turning off?

Hello,
Wondering if anyone can shed some light on why my Tab keeps turning off when left for several hours? A perfect example is leaving it on in the morning with just uTorrent running and when I return in the evening its turned itself off. Has only been doing this for a few days for a few weeks, prior to that it was fine.
Here's the spec:
GT-P7500 with stock Rom
3.2
P7500XXKL4
Pershoot kernel 2.6.36.4
HTJ85B P7500DXLA2
Any ideas as to why this is happening would be really appreciated.
Thanks guys
Not really a solution to your problem, but does it also happen when there is no torrent client running in the background? I found that whichever client I use it usually freezes after some time and I have to reboot the Tab (I'm on GalaxyTask 14 now, but it was the same on v13 and CM9), so maybe this is a cause of what you're experiencing?
I take it you ruled out power saving settings or that it ran out of battery, right?
Well it never used to go off and I could leave it on all day downloading and it was fine. Last night it was left on with no torrent running and was on this morning, ran uTorrent this morning though and it was off when I got home. It never ever done this until recently however?
No settings have been changed in respect of power management so it's not that no
maybe the best and safest option is to link it to odin and flash a stock rom, without any kernels. and see if the issue remains mate.
if this post helped you in any way, please hit thanks button
There seems to be alot of issues with the stock HC ROM's would suggest you try a cooked ROM or something

So, have you tested it more? Is there a correlation between the GTab turning off and torrent running in the background? For me it also started quite recently, although I can't really say when as I usually torrent stuff on my laptop and then transfer to GTab. I was trying 2-3 torrent clients and it was all the same - the GTab was freezing after a while, in particular when I watched something.
I guess too much stress on the GPU forces the tablet to save itself and shut off. Even the smallest torrent client eat's up about 100% GPU if not set to control properly. The same applies to the tablet, it lags hard without a performance governor to set the GPU @ 100%
Well it's definitely tTorrent that's been causing it to shutdown (sorry called it uTorrent earlier in the thread).
Have run it all day and through the night with nothing running and it stays on with no issues. So, as others have mentioned the same problem with other clients does anyone know of any performance governor software that can manage the GPU and stop it getting spanked?
Would also be nice to know why this has suddenly happened, I've been thinking that this has only started to happen since an update via Kies a few weeks back.
Like it's mentioned, use pershoot's kernel, to OC it and use something like Nofrills, it's free to manage the governor and I/O

When does the reboots happen? When you do something specific, like playing heavy 3D games? Maybe overheating causes phone to restart. Have you checked temps of CPU?

totaly random
Is that the latest firmware available for your model?
I've experience random reboots as well after I flashed the pre-rooted TWRP with .167 system and kernel. I've also noticed that the phone reboots frequently when downloading apps in Google Play.
i had rr yesterday (always when phone goes to deepsleep) and solved with a factory reset, then installed one by one mods checking there are no reboots
Doing a clean install/flash, wiping dalvik cache, and bumping max cpu clock speed to 1.459 GHz and min to 400 GHz seem to fix the random reboots on my .167. I haven't had a rr for a week now.
Edit:
I was a doing a little more browsing and I think I found the solution over in the general forums. It sounds quite promising and seems like it's stood the test of time (which is 4 days that's been recorded) I'm in the middle of trying this method and I'll get back to you guys in a few days if it actually works.

Good luck

I've even had problems with random reboots on the stock 26.1.A.1.112 Commercial & Journalist version with nothing but being rooted. So i don't think it has to do with programs.
In my honest opinion the problem seems more to do with the stock roms having a problem with root on a bootloader locked m4 aqua.
The only thing that I know can almost certainly cause a reboot is updating apps on the play store. I'll usually have at least 1 reboot during that.
I've been fortunate enough this time around only receiving a reboot about once per day which is manageable for me but it's still an underlying issue.
Any new insights into this would be great. Maybe we can collaborate.
Likewise. Although i can sometimes get about 2 days without rebooting. But i do notice that the reboots are usually when updating apps,(though not always) or randomly when battery is fully or almost fully charged.
Currently on 3.111 rooted, xposed installed.

Dude, try this! I've been running from a fresh install to having over 6-7GB of apps installed and my phones been on for hours now with no reboots.

Thanks man. Bit of a hassle though. I might try it though when i have more time.

That's awesome. You won't regret it. I gave up on having root awhile ago because of the reboots and I'm so happy that this fix works. It feels so freeing!
If you need any help when you do go for it, feel free to message me.
Good luck!

How do you bump the cpu clock speed?
