Random Reboots

OK I'm tired of seeing people complain about random reboots even though its been discussed multiple times. So here's a true story to help you all out.
I was on octane 3.0 problem free when I decided to go to Valhalla black final. I had reboots and force close issues. I went back to octane 3.0 and started having annoying force close issues. Now I know its time to start fresh from stock since I haven't cleaned the gremlins out of my phone in so long.
So I download kies mini for the drivers (since I got a new laptop in December) and pop in a DVD that had a backup of all necessary files (odin, kc1 and whatever was in fbs original gb starter guide, I want to say kg4). I load the kc1 files in Odin and Odin freezes at checking connection.
I unplug my phone, pull the battery, reinsert the battery and put it back into download mode (which is now a pic of a phone with a cord running to a computer), I then restart Odin with the kc1 files and everything goes through fine. I then do the kg4 files, once that's done I reboot into cwm and flash bhundvens latest kernel with the newer version of cwm.
Once that's done I flash Valhalla black final fixed followed by Valhalla booster. Now I've been running flawlessly for over 24 hours so its about time to UV/OC. Once I UV/OC, if I start having issues I'll know I need to change my UV/OC values, since I wasn't having problems with stock voltage.
Alternatively you can use bhundvens heimdall package that already includes his latest kernel. I just stuck with the files I already had saved cause my home internet sucks.

Thanks... I'm planning to do pretty much the same this afternoon. I had the reboots, but they stopped for a few days when I reflashed rc1.1 kernel... started happening again yesterday, so I flashed 2d, but still getting reboots.
Figured it was time to start back from ground zero.

I only had reboots when attempting to access the messenger toggle at the lock screen, Drive smart, and battery history in spare parts.

1) mess. toggle= you have to set that via settings> tweaks (or edt tweaks)> lock screen settings> choose custom app
2) drive smart= labeled "bloat" & removed
3) spare parts= I don't believe there's gb support... Though you can access via settings> about phone> battery use
Hope this is helpful

Very helpful I appreciated it. =D, I just changed the lock screen and wasn't going to use those, they bare no real importance and the ROM functions amazingly.

Wow i had same problem with odin at setup connection but i did not.try.odin again yet as my.phone is already at stock and im about to cancel the contract.and get another phone as its not been 30 days yet. I am thinking of trying odin again.

To add to what QUIETLYloud wrote - Spare Parts is GB supported according to the app description in the market, but it also tells you not all phones store battery history and if your phone does not store it you will FC if you select that option within the app.
Add: I decided to uninstall Spare Parts that came with the ROM and download Spare Parts from the market. No more FC on battery history.

Is it a completely different version or just newer?
Installed this and still force close on battery history selection. Im batting 0-4 tonight. /sigh

yes the messageing icon will fc and cause a reboot if you do not assign a button to it... I should add that to the op its inteintally left un assigned so you can assign whatever you want to it though tweaks...
Spare parts battery status will fc it was the only version i had at the time but the newer one should be ok if you wipe the data from it then force close uninstall and download form market ... If not wait tell they add better support.

There are a couple Spare Parts in the market. The one I used was Spare Parts+ (no ads) by DroidGram. It worked for me.

The weird thing is using a widget for the battery shows the history just fine. Spare parts is a weird animal.

So, I flashed Bryan's d2 version of the kernel yesterday and am now going on 33 hours without a reboot.
I'll leave it on the charger for the night and see what uptime is in the morning, if no reboots over night then I'll flash back to 1.1 and see what happens.
speaking of charging.. I am at 73% battery life at 9 hours on battery, so bat life is looking good

I think it is newer. But if you are using the one from the market, make sure you removed the one that came with the ROM.

I'm on Bryans 1.1 which has yet to give me any problems.
I've been playing with UV settings (always OC'ed @ 1.2) trying to find the right settings for my phone. I think I'm finally making progress, I had been getting a reboot within 8 hours, on my current settings I've just hit 12.
Once I hit 24 hours up time I'll adjust again and see how it goes.

I have the random reboots to and i used the back to stock one click, but I still get the random reboots. However, it only happens when I restore my apps thru TB. Is it possible one of my apps has some sort of "virus" causing it to do that?

Actually TB causing problems is an issue that has been discussed. Personally it hasn't given me any issues, but I've read after flashing a new ROM you should only restore user apps. So don't restore app data or system apps.
Its worth a try anyway. Otherwise one app causing your problem is a possibility, but depending on how many apps you have it could take a while to restore one by one til finding the problem one.

I am having some random hangups followed by reboot when I'm using stock browser. I'm on rooted but stock GB KJ6 with stock kernel. I never had such behavior when using other apps. and it does not matter if OC or not.
Well, I'll try another browser for a while and will report back.

[Q] Exhausted all options

Hello,
I have been struggling with this issue forever. I am using my Google nav app and all of a sudden it freezes barely updating with CPU @100%. I have tried different options using 3g instead of 4g, not using bluetooth, not starting nav when CPU is busy nothing has worked. All of a sudden either at the start or during a navigation session the CPU will go up to 100% and the app will stop updating and if I am driving I left without directions until I reboot. Huge headache. I used different system monitors like 'WatchDog Lite' and 'System Tuner' and those apps say that the most CPU consuming process during that time period is 'Android System Process'. I have no clue as to what 'Android System Process' is doing during that period of time except it is taking a large amount of CPU.
Only option left is to overclock, upgrade to a faster CPU from Verizon or go to Apple IPhone

That's strange, I used the navigation all the time without a problem, besides slow locks. Have you tried clearing the app data, sounds like its the app itself misbehaving.

I haven't had an issue like that and its definitely abnormal. Have you tried installing a ROM like Tweaked or a kernel like PBJ?
Sent from my SCH-I510 using xda premium

I had the same problem before I rooted and installed my first ROM. No problems since then. Recommend you root, install Tweeked or Eclipse and PBJ, also don't undervolt too much. You're headache should stop. I haven't had that happen to me in long long time. I'm a truckdriver and use the maps quite often.
Sent from my SCH-I510 using XDA

I had the same problem star up all of a sudden a month or two ago. Google maps would just close by itself, and nav would freeze while driving. While messing around one day, I ended up having to wipe my phone and ODIN stock, re root, and put Tweaked 2.1 ROM on it again, and restore all my backed up apps. To my pleasant surprise Google maps and nav are working flawlessly now.
Sent from my SCH-I510 using XDA

I have been partially able to fix the problem. One I downloaded Copilot Live as a navigation app which uses offline maps instead of downloading maps on the fly like google nav. However, still my phone used to lag close to 20-30 seconds when I would go to my home screen and similarly when I went to my application lists. I was using Seepu so I could see that my CPU was at 100% all the time. This led me to believe that there might be an issue with my SDCard and hence I downloaded sdbooster https://play.google.com/store/apps/details?id=de.mehrmann.sdbooster&hl=en .
I saw an amazing performance improvement after I set the cache size to 8192 mb and the lags all but disappeared. However, still when I am on my home screen it sometimes lags 5 seconds which is still infuriating. What the heck is it doing, is it reading apps from the disk?

Jelly Bean Issues

Hello!
After updating from ICS to JB 2 months ago I constantly facing with different problems with. I was enjoying ICS and expected best experience from JB.
First of all I missed all of my media files from SD. I searched xda for answer and discovered same issues. All answers was, like, "delete .nomedia and/or wipe your device". I didn't have ANY .nomedia file on my SD. So, I forced to wipe all of my data, app settings, etc. and recover it again. F*ck, why I must format my phone to make it work properly? Sometimes I have known bug with stock launcher when it doesn't show any icons or render one icon to whole screen. Sometimes my device freezes and I only can reset it by ejecting battery. Very poor battery life. Several days ago my battery suddenly dropped to 0% from 60%! Look at pic in attachment.
But main problem with JB is performance. With ICS I hadn't any lags in simple games such as Cut the Rope, but in JB I often facing small freezes and lags that highly annoying. Sometimes one game running OK, but next time it very sluggish. I can't understand why. I constantly have ram issues. In ICS I saw stock launcher crash very rarely. But in JB after every Internet surfing or gaming I must wait to stock launcher load. More frequent is widget issues. When I press Home button I see that stock calendar widget blinking. That seems like it loading or reloading.
So, the main question is: what can I do with this? Is there any custom rom that hasn't this issues? Can I cut some JB features to increase it performance? Is there anyone that have same problems?

I'd already solve this problem with wiping, but I didn't touch any of my media files. I don't think this was caused by corrupted file.

Wipe is necessary when you flash a brand new rom. I've experienced the same issue upgrading to jb from ics, solved by doing a full wipe!

Of course I did this.
Also, sometimes I stuck with (bug?) android.server process consuming all CPU. Only phone restart helps.

I don't have a lot of complaints, and haven't had the same performance issues, though I don't do a lot of gaming. That's what the Nexus 7 is for.
The media scanner in Android sucks in my opinion, so if your files aren't showing up you may want to try running something like SDRescan. My music files (in Music directory on SD card) will show up as soon as I re-open Play Music.
You could try turning off Google Now if you haven't already. I did that and the battery seems to be a little better.

OP, I used to have the same problem and I could never find the .nomedia file. I had to delete ROM manager and its folder. After a full wipe and many tries, I got it to work. As for the launcher crashes, you might want to download an alternative from the play store. One that keeps it "in memory", that way it hardly crashes. I have Nova launcher and it happens frequently to where I switched to Apex haha.
This helped me and hoping it helps you. Good luck!

[Q] Apps launching slow

I am on CleanRom 3.0 right now, fresh install. Now, for the problem. Today while sitting in class I took my phone out to see it was booted into safe mode. So I rebooted it back, and noticed a lot of my downloaded apps were launching 10-25 seconds after I clicked to open them. So, I rebooted again. That didn't work. I cleared cache and dalvik cache. That didn't work. So, I dirty flashed CleanRom 3.0, which still didn't work. After driving and listening to spotify in my car, the apps launched completely fine, and still are. Does anyone know why this is happening? By the way, this happened on my rooted stock rom, that's why I switched roms. I don't know if this could cause any issues, but I do use Directory Bind.

Have you checked if power saver is on?
Another possibility could be a lot of applications running the background and just slowing your phone down.
Check your task manager by holding the home button for about 2-3 seconds.

Yea, power saving is off. And there isn't any apps running in the background when it's ran slow. Most stock apps will launch fast (settings, phone, clock), but downloaded ones won't (I funny, handcent sms). I seriously can't figure out what the issue is. I've even tried messing around with set cpu, but that didn't help.

Poor Performance ,Even on CM11

Ever since I got the TF300T, I felt it was a little sluggish at times. I assumed it was because of all the bloatware and/or the Asus ROM.
I've dealt with it ever since I got it, which is pretty much the day it came out, and I'm tired of that.
I really hoped Jelly Bean or KitKat would help so I unlocked the bootloader, flashed TWRP and flashed a CM11 nightly. (From the 18th I think.)
Its been running for a few hours now, and I feel like its just as slow as before.
I'm aware I could buy a newer device (like a Nexus 7 or 10) but that's not an option right now.
I'm also aware that I could try another ROM like OMNI or Cromi but
(a) I choose CM because I've used their ROMs in the past and I trust them, and
(b) I'm not really in excited about trying 2, 3 or 5 different ROMs
Is this the sort of performance I should expect from this device?
Is this as good as it gets?
Sent from my TF300T using xda app-developers app

You should see a significant performance improvement from stock to CM11. For example starting or switching applications is much faster.
Can you describe in more detail, what you are doing, and where you consider it to be slow?
Sent from my TF300T using Tapatalk

Did you wipe /data, /system, /cache, & dalvik cache before you flashed CM11?

what he said
like ebildude said make sure to do proper wipes before installing rom. i've personally only used cromix and it works great, even though it's stock based - theres lots of tweaks. also look into getting a fast microsd and take a look at rom2sd ,data2sd and cache2sd tweaks in the cromi thread-may boost performance a little. hope you get it working to your satisfaction, this is really a good little machine when it works right, can even dual boot linux, look at the xubuntu thread.

Try installing a kernel, like GEASS or GRIM. Then use overclock and a new scheduler.

I flashed it yesterday afternoon around 3pm and didn't do much with it other than

I haven't loaded it down with apps, yet.
In general, moving about the device seems choppy (not smooth) and its not responsive whether I'm

When turning on the screen it takes 5-7 seconds before the screen actually turns on.
Launching applications or games aren't any faster and there's some stuttering when watching media. (Like HBOGO)

I really like this device for a variety of reasons, and I'd love to dual boot Linux! (I'm a huge FreeBSD and Gentoo fan!) Despite how sluggish its been, I've gotten a lot of work done on this device. Well via things like Citrix and LogMeIn. When traveling we use it to watch TV and do things that would otherwise be too difficult to do on a phone.
I have a 32GB Class 10 microsd in the tablet and 16GB Class 10 SD card in the battery/keyboard portion.

Something just occurred to me: Could it be that the system is scanning the SD cards? One is mostly empty (twrp backup, files for flashing) but the other is packed with data. (Maps for OsmAnd, TitaniumBackup backups, music, photos and other stuff etc.)

The TWRP Factory reset wipes data, cache and dalvik not including internal storage.
The advanced wipe let's you choose the option to wipe everything, but I only did cache and dalvik.
Also after flashing a ROM TWRP has a convenient 'Wipe Cache/Dalvik' button on the screen, which I did.
So to be sure, I just did a factory reset again , followed by an advanced wipe wiping everything except my memory cards (Data, dalvik, system, cache). I reflashed CM11, wiped cache and dalvik then flashed the gapps.
That sufficient?

Opening recent apps can sometimes take 2-3 seconds, especially if there are a lot of recent apps and it has not been used in a while. But usually it is less than 1 sec. Everything else you list should be very snappy, less than 1 sec, usually far less.
When turning on the screen it takes 5-7 seconds before the screen actually turns on.

That is indeed possible; maybe it is waiting for the device to settle, especially during the long screen-on time.
Any improvement, if you remove the sdcards?

Ok its been about a few hours since I wiped + reflashed and I have a bittersweet update.
The Good:
I'm noticing an immediate improvement this time around!
+ The CPU is now at a more reasonable 0.1x-0.2x versus a constant 3.xx - 5.xx!
+ When waking up from sleep (pressing the power button) the screen is on almost immediately versus 5-7 seconds.
+ Opening the app drawer, moving between screens is not only faster (more responsive) but its not as choppy. (maybe completely lagless)
+ In general its noticeably faster.
+ I installed Netflix, HBO GO etc and playback is smooth.
The Bad:
- There's still the occasional slowness in general, although not as frequent, but its especially slow when downloading & installing apps. (like it hangs)
- It was running nicely *until* I added a second user. Immediately after creating the account, there was a significant decrase in performance. I noticed this in the stock Asus ROM even after wiping and not installing anything. Not sure if this is an Android thing or unique to this device. (Also, it just rebooted right in the middle of creating the account; fluke I suppose as it didn't happen a second time.)
- CPU is now hanging around 0.3x - 0.5x after adding the new user. I assume its caused by whatever background processes associated with the new account but the 'presence' of the new account is being felt.
While I'm not excited about the cons, its considerably better than what it used to be.
I'll test without the microSD & SD card tomorrow and let the system 'rest' and 'settle' for tonight.
Your input has been invaluable and I'll keep pressing on!

Most ROMs lag when updating from the store etc. Just turn off auto updating and do them manually and don't use the tab for 5 mins whilst it is updating.
As for multi user - it's bawked - never seen it work well on any device. I'd forget it for now as the performance hit is not worth it.
