(xoom 2) XOOM 2 10.1 Freezing & Reboots – A SOLUTION! - Xoom General

I just wanted to share with you my recent issue & solution to the XOOM 2 rebooting issue.
Now to give you an overview of my situation, I purchased the XOOM 2 10.1 UK back in January 2012.
I use it almost every single day. No surprises I was getting random screen freezing followed by reboots every single day. Most days twice!
Now I was hoping that when the update happen back around 2 months ago that it would solve this issue. It never.
In fact my freezing & reboots were happening more frequent.
Basically within 5-10 mins of using the Xoom2 it would reboot.
Some days I just wished I could throw the dam thing through the wall.
I rooted using Dan’s method. The only method. & tried various ways to solve the issue.
NOTHING worked.
In fact, I was convinced that my rooting & installing things that should not be there was making the reboots worse.
So I cleaned up my Xoom 2, went into recovery, wiped cache & cleaned data & rebooted.
This still did not work.
Then I tried task managers, cache cleaners & even paid for that system panel app that logs all apps & usage.
Nothing worked; I was still getting the reboots. Everyday.
So after looking over many Xoom 2 forums & with many issues and complaints about this issue, I was close to selling & getting an iPad.
I was convinced it was hardware.
Then I tried this way:
1. I rooted.
2. I installed ADW Launcher & made default.
3. I installed SetCPU
4. I installed Titanium Backup
5. I froze the stock ‘launcher’ – (whatever you do – do not un-install any app, you CANNOT update Xoom if you do)
6. I changed CPU from ‘hotplugmoto’ to ‘performance’ 1200min 1200max
(I know you might think this uses lots of battery but I found not)
7. Set up setCPU profile for ‘screen off’ I use ‘on demand / 300 to 600’
Battery over night on this setting did not go down by 1%
8. Rebooted.
After 4 days of constant use & trying so hard to get the Xoom to freeze & reboot – I can’t.
This method works.
I have surfed using ‘Firefox’ while using ‘Currents’ while using ‘Google+’ while downloading files and steaming music via ‘Google Music’. I have open every single app & been quickly switching between them all trying to over load the system.
Nothing will freeze or reboot my XOOM 2.
What I can get from this is that the Xoom 2 works perfectly.
With the high CPU set, it is so fluid and lag free. It works almost perfectly now. It also means the hardware is absolutely fine.
Maybe with newer firmware updates in the future this will be sorted naturally.
I makes me think something with the high CPU means a bug in the processing won’t make the Xoom freeze & reboot.
Until then this method works for me and I can’t see why it won’t work for you.
If you are having this issue I hope this helps.

I messaged you on the Motorola Forums, but I think they may take it down since they don't like talks about rooting.
But thanks for posting this, I will give it a shot.
When you changed to performance 1200 min/1200 max - I'm guessing you also checked set on boot? right?

Yes i ticked set on boot. Make sure you have a screen off profile otherwise it will be running at max all the time.
Hope it works for you.

Hi,
I froze some bloat before and uninstalled flash 10.3 cause flash streaming online videos didn't work 4 me (neither 10,3 or 11,x), then installed flash 10.2 and all starts to work ok but still 2 or 3 reboots for week.
Also seems that "memory booster" app helps when some apps starts to freeze and u can finish em and free some mem.
So now i'm trying setcpu and then i will do launcher trick
Thx a lot!

Vanpeebles, Did you switch launchers because you think it will help the reboots? or because of personal preference?

List of frozen apps
List of frozen apps 2 months ago without issues:
App used: Ultimate Backup
Amazon Kindle (I dont use it)
Citrix Receiver
Drippler Motorola DROID Xyboard 8.2
Drive
Fuze Meeting
Google+
GoToMeeting
Servicios de estadisticas de dispositivo ("Device statistics Services")
Twonky
Good luck everybody!
Now i'm not expecting ICS, this is working almost perfect. Let's see setcpu improve.

It does seem that the source of the freezing/reboots is the Motorola Launcher. Since I switched to Go Launcher HD I've definitely seen less freezes.

Hi
I switched launcher on personal preference but to be fair I have had no freezes now for 5 days
So I'm not messing now if it ain't broke.
The reason is I did this is I read 1 post on another forum that someone changed launcher &, this helped him.
So wether launcher or high cpu I'm not bothered
To finally have a working tablet is such a huge relief!

Thank Vanpeebles,
I did everything you said and now hoping for the best!
Either way, I'm loving ADWLauncher Ex..... sooo fast and snappy!

Thanks my Xoom 2 is running great again!
Also add this warning. Do NOT remove the Launcher2 app if you do then your Xoom 2 will never boot again and the is no current way to fix this because of the locked bootloader.

That's my question, why do you even need to freeze the stock launcher if you've set adwlauncher as the default.. like what's the point of that step of freezing the stock launcher, it shouldn't impact performance.

No he is right, because the stock launcher takes a big bite out of your RAM around 100MB. And even if you do have another launcher running that stock launcher always seems to be in the background on my tablet.

Yeah but won't freezing the launcher (or changing its name to launcher2.apk.bak) cause problems if your tablet faces a failure and the adwlauncher crashes?
EDIT: I guess titanium backup unfreezes apps if you do a wipe so the best option is to freeze the stock launcher (NOT uninstall it and NOT rename it)

Over 1 week now and not 1 reboot.
I can't answer these questions on the launcher?
All I know is this works for me, I have had not 1 freeze or reboot, so the stock launcher can stay frozen.
(it may have absolutely nothing to do with it, but I really don't care)

Hi after several days over GO Laucher EX (or HD "Tablet version but less customizable") with Setcpu 1200 1200 performance and etc....
only 1 reboot when several web pages were opened on stock browser with flash videos etc.
I've noticed that now when apps stops to work it goes back to home instead of reboot except that time.
Almost no free ram and that's seems to be the clue..Stock launcher doesn´t free enought memory
And battery drains suddenly stopped.
Super happy man . More fluid launcher, more customizable, and also wifi starts to work better when comes back from sleeping
Thanks for not to give up!

Have to say... this solution seems to be working very well. I'm running set CPU in conjunction with auto memory manager set to "aggressive" and AdwLauncher Ex!
Using many apps that in the past would give me reboots, but now they are working flawlessly.
Thank you very much for this awesome contribution!

I'm Xoom 1 user and also having annoying reboots you described here. Most of all it happens when watching movies or iptv in player.
But isn't setting cpu frequency to 1200min will force cpu run at 1200 not less all the time? It probably may overheat the cpu and sounds dangerous.

When its in use yes, but you also set a second profile to turn down the cpu to a lower value when the screen turns off so you don't drain battery and cause overheating!
So far - I'm running this method without any problems, no noticeable battery drain or extra heat in anyway!

I'm currently running on stock kernel without ability to scale over 1000. Tried to set to performance governor only, but failed and got regular reboot during usage. Will try your method.
Seems to be it's operating system problem. Don't understand why motorola still didn't resolved it, including that fact that problem also present in first Xoom model.

Worked a bit around with your solutions and stabled on the following:
Stock launcher frozen;
SetCPU profiles:
Screen ON/unlocked: Governor OnDemand (1200-800) with Noop Scheduler
Screen OFF: Governor standard hotplug (800-300) with noop scheduler
It looks like moto_hotplug governor doesn't work quite well but I also noticed some glitches on systemui.apk. Whenever you turn your screen on and unlock doesn't show smooth you must turn off screen and try again... if you unlock with a laggy unlocker the whole system will be a mess.
With those setting I'm not having reboots, just some lags here and there; battey, however, lasts much less due to ondemand governor.

Problems with 101 after setting clockspeed at 1000 mhz

Hi. I have an archos 101 8gb, any one having problems after setting the clock speed to 1ghz?
Usualy screen freezes up and I can do anything unless i restart the device by holding the power botton 10 seconds, I notice this problem most of the time happens when using the market(gappsv2) or browsing the internet
I use setcpu 2.0.4 (ondemand) and z4 for temp root
This has never happened to me while running at 800mhz
When I updated to froyo I used the aos file and reformatted the device, I was having problem with the ota update
Any reccomendations? Thanks

How many 3rd party apps do you have installed? What all is running in the background? What Task Manager are you running? Maybe since you have temp root you should install Titanium Backup and freeze some apps and uninstall others.
The lockups happen to me far more often at 800mhz than 1ghz. It could be due to the market but I had lockups before I even installed the market and rooted so I'm not so sure they are the cause. It's almost like a process goes completely nutz while the system is in hibernation and it won't come back out.
There are tons of reports on this. Hopefully they stabilize the system with firmware updates. I don't think there is much you can do about it.
I've had issues at both 800MHz and 1GHz, but only since the firmware update.
Temps aren't rising at all running at 1GHz, so I find it highly doubtful that clock speed has any direct affect.

there's no temp sensor in it as far as i know btw
I have myspace, doodle jump, andry birds, abduction, bluetooth file transfer,autostarts(withsome apps starups disabled), fring, pandora.
I use the default archos task manager, and kill everything except the "android system"
I haven't overclocked to 1000 for a while and now the locks starting to happen at 800 mhz while playing doodle jump
So it seems its a general firmware problem, or maybe the gapps has smething to do with this, anyone without the gapps is having this problem?

I used the gAppsinstaller_v3.apk located here on my 70 and havn't had any issues

I have been on the 2.2 update for a week now, running at 1GHz, and I have not experienced a single lockup.
The only 'issue' I have is with the Slacker app losing its connection every so often. But that also happens on my Evo, so I think it is a Slacker deal and not the A101.
Which gapps version did u used?
Does any one know how to unistalled gapps v2? I heard the only way was to do a factory restet..how true is that?

While its not good that you're getting lockups at least by it still happening at 800 Archos will not have another excuse to be downclocking it to 800 instead of the original 1000. I've seen a few people post that switching launchers (to Launcher Pro or ADW.Launcher) they have stopped having freezes on their systems. Since you didn't note a different launcher in the apps listed above it may be worth a shot for you to try a different launcher (from the standard Archos one) and see if that reduces or stops your freezes.

[Q] Random lock ups freeze

I keep getting random lockups, at least more than once a day, and sometimes several reboots in a row.
It appears that i can happen almost any time, whether it be at a lock screen, while titanium is asking for root, or opening twitter or facebook, even the gmail app. It simply freezes, and requires me to long press the off button and reboot.
Unfortunately, i can't get adb via usb to work on the nook, so i can't get a reliable logcat.
Is this common? I have had two nook devices so far, tranferred the rom over through nandroid and have had lock ups on both, I am flashing regular cm7 nightlies now (emmc), but it occured using phiremod too.
Help?
I never had one, maybe I'm lucky
Have you tried fixing permissions in clockwork?
Sent from my LG Optimus V using Tapatalk
I am having the same problem. I loaded CM7 to my emmc yesterday and I have had it freeze on me a couple of times now. All have been random. I do have performance set to 1.1 and on demand gov set.
So I can just go to ROM manager to fix permissions? Hopefully that works.
EDIT**
Did not work. Was fine, then I uninstalled market updates, connected to wifi, opened the old market, searched for flash and it froze up. Any ideas?
EDIT 2**
uninstalled beautiful widgets (read that somewhere), so far no lockups (fingers crossed).
i had mine lock-up twice last night
i was in dolphinHD and i had just installed swype beta
i have only had 1 time that it has locked up before then in the last 1-2 months that i have had it.
im blaming swype, since i havent had the problem in the past
perhaps not your problem, if you dont have it installed.
I get lockups pretty regularly. It's irritating. Not sure what the cause is. I thought overclocking had something to do with it but everyone else is overclocked and this problem doesn't seem to be common.
How low do you have the voltage settings in tweaks? Having a voltage just barely too low for your CPU can cause a lot of weirdness. Also, it could be any one of the stepping voltage settings, not necessarily either the min/max frequency.
Folks, playing with the voltage settings in nook tweeks is not for the average user. These settings can really bork your nook. That's why you get a warning when you open those settings.
That being said, I have been running cm7 on eMMC for months and have never had a lockup. I am overclocked to 1200 mHz but have left the voltages alone.(cm7.1 nightly 160).
If you are running on eMMC,try fix permissions first. If that does not help, start looking at the apps you are running to determine if one of them might be the problem. Several people have reported issues running beautiful widgets. There are other apps that can cause issues. If you have good backups of all your apps, try removing apps one at a time. In the process, you might learn something about your system.
Worst case, reinstall cm7, wipe data, cache, and dalvic cache. Start over with a clean system and add your apps (apps only, not apps+data) one at a time. This will ensure that a possibly currupt data set was not causing the issue.
The key to a fast, well functioning nook is to start slowly and ensure each change works well before moving on to the next step.
While it's true I have more time than most to play (retired), my nook can run circles around most competitors but only because I took the time to set it up right the first time and I am not afraid to wipe everything and start over.

I fixed permissions some time ago, seemed to help a bit, but i still get the odd lock up or two. I am running Swype and Beautiful widgets(anyone know a good alternative?)
I had been getting irritated by these these random locks up for a while. It seems that uninstalling beautiful widgets fixed the problem for me. I thought it might be that BW was trying to access the GPS, but it still locked up after disabling geo location in BW.

In case you're still interested, BeWeather is a great substitute for BW and FlexT9 in place of Swype.
Also, I had issues with lockups no matter my overclocking and formatting the eMMC and possibly reseating the SD card fixed it.

Why does my DZ fail me when I need it the most

Now I love my DZ; it is by far the most capable phone I've ever owned, but it has this nasty habit of failing me whenever I seem to need it the most.
For example, today I was stuck behind a huge accident on the highway with an exit coming up in a few feet. I thought, "hey I'll just see if I can find a detour around it from this exit." Pulled out my phone and quickly launched google maps. right then, it completely stops responding to all touch input; the trackpad and physical buttons work fine, but nothing was registering on the touchscreen or capacitive buttons. I eventually had to pull the battery to fix the issue.
It just seems that these things tend to happen whenever i need to lookup something quickly on the phone (when im just screwing around on it, it works perfectly fine) be it completely not responding to touch input, or something weird happening like getting stuck between 2 homescreens, or the notification panel gets stuck halfway down, or massive input lag (5+ seconds) to the point of it not being usable.
And everything goes back to normal after a reset; but by then, I usually don't need to lookup whatever it was anymore.
The most frustrating part is that I can't seem to figure out whats causing it. I'm running virtuous 2.0.0 without any sense 3 additions, and I generally only have 1 or 2 tasks going on on the phone at once (usually just music player + whatever I'm doing). I originally thought it was just a performance issue, so I've increased the clock up to 1.5ghz (using daemon controller) but it hasn't has of an effect.
Any ideas on what else i can try?
Sounds like simple bad karma, I suggest donating to a charity or going to church
Other than that, I'd have no idea, sorry. Seeing as its not totally regular, there'd be no good way to easily pinpoint the issue. Maybe see if the rom produces a last_kmsg?

although people say roms are 'stable' and can recommend these ROMs as "dd" (daily drivers) you cannot say that will be completely reliable. This is because when people say a ROM is 'stable', it's only after using it for 2-3days; unfortunately, roms gather clutter and begin to slow down over time. Not a problem for many flashaholics, but a problem if you're a one-rom kinda guy (or girl). So if you're not one-night-stand rom kind of person, here are some tips:
Reset your phone regularly. Phones start acting funny when they've been on for too long
Try stock ROM with addons flashed on top of it, rather than baked in a new rom
Most reliable roms i've experienced are Stock Gingerbread or CyanogenMod. Try those
If you are flashing a new rom, use SuperWipe, this can help get rid of clutter from old roms

Hmm, so you believe that this is purely a rom issue?
I havent run a stock rom for a while, but from what i remember the experience wasnt that pleasant, there was significant lag almost everywhere in the ui. Although i will admit that was back with froyo; i havent tried a stock gb stock rom yet.
Ill probablygive cm7 a go. Ive just grown so used to some sense features that its going to be hard for me to give them up (mainly recent apps in notifications, news widget, t9 dailer+manually linking contacts, and remote ring and forward on htcsense.com)
Has anyone had similar issues running virtuous sense 2.0.0?
As far as recent apps goes, long pressing the home button is a standard feature of android that brings up the most recent. Stock is the last 8 (I think) cm7 can show 15.

Higher overclocking will make your phone LESS stable, not more. I'd stick around 1 GHz, as this is known to be very stable on most Z's, and usually does not result in any significant additional battery drain. OC may not have anything to do with your random hangs, but its probably not helping either.

I'd agree. I really wouldn't ever go over 1.2ghz for a daily driver personally.
I run my ROMs at 800mhz lol, so I don't see the advantage of a huge overclock unless you're just bragging about benchmark scores.
its funny when u wanna show off your phone and you take it out of your pocket acting all cool and stuff and when u press the power button it wont wake up or you get a blank screen
haha its just bad karma for u like nipqer said
Try the stock pre-rooted gingerbread...I just flashed t last week and it is way faster than my froyo was, and amazing battery life, for me anyways, I do have an extended life battery though lol. Anyways as far as speed it is snappy on 800 mhz

I've noticed the random hangs / glitches @ 800Mhz and 1Ghz, so I'm hesitant to say that the OC is the cause.
What do you use for stability testing? I've been running quadrant nonstop to test new OCs, but I don't think that benchmark stresses the cpu enough.
i am running Virtuous v2.0.0 w/ kernel unity v6 on it on desire z.
i've found bugs like
1/the top black bar ui, top left corner, some times i see the background wallpaper rather than the black bar. but it goes away if i pull down the notifications.
2/ the mail with microsoft exchange active sync, if i delete the mail it will automatically resync and downloads all mail including the on i deleted. but i got around that by using pop/imac instead.
all rather minor as i got ways to go around it.
i did have a similar issue where the touch screen goes unresponsive and i had to force close it, restart phone to get it back alive. but then i readjusted the clock speed and never had it happened again.
the phone is at around 825mhz with governor smart ass on wake time max, unless im watching 720p movies on the phone then i ramp it up at 1.4ghz.
sleep time on 368mhz max with governor at conservative.
i had it on like this since 11/09/11 (as i made a rom backup) and it never occured yet.

I've been playing with the wake min and wake gov settings the past few days. I have it set at 600Mhz min, performance gov; I haven't noticed much difference in the battery life, but I'll have to do more extensive testing to be sure.
Performance feels slightly better, especially after a fast wake. can anyone give a detailed explanation of the behavior of the different gov settings? I can't seem to find much info on it.

Tip: SetCPU Settings

I may be the last Streak owner on the planet to discover this, but if I'm not, I hope it helps someone else!
I have had my Streak for over a year now and have used many of the great ROMs from DJ Steve and others. I am currently on Simple Streak 1.2 with PerfUpdate. It serves my purposes well.
To the point, for the past 4-6 months my streak is hard to wake. The screen turns on but is unresponsive for about 10 seconds and then the FC window pops up with the choice to wait or FC. It happens on every app that is open when the screen turns off, most usually in ADW. I have tried several of the newer ROMs and different launchers thinking this would correct the problem, but it hasn't.
It occurred to me that the one thing in common with all of the ROMs I have tried/used were my SetCPU settings. Since I have my Streak plugged in most of the time at home or in my office, battery life isn't an issue for me. I have been running SetCPU on the PERFORMANCE setting. Several days ago, I changed it to the ON DEMAND setting and the hesitation problem vanished completely! I have tested to be certain this was the cause and I am 100% certain. If I go back to PERFORMANCE, hesitation starts immediately. ON DEMAND, zero hesitation. I have noticed no slow down in performance otherwise. The numerical values and the various profiles have not been changed except for setting to ON DEMAND.
Again, I hope this is useful to someone. Please don't flame me if this is old news. Thanks.

Yeah, I tried other governors, but I prefer Ondemand. It is the most reliable in my opinion.
ondemand is the default governer for the stock rom/kernels,
the only time it's not ondemand is if it's changed by the rom (at startup) or by the kernel itself (as a default option)
Regardless you should NEVER use performence as a normal use governer as it keeps it at max speed the whole time, even while it sleeps.
i agree, ON DEMAND is what i always used for gov
most reliable for me
but, sometime i changed it to CONSERVATIVE too...
I've all ways used the above 2 except with StreakDroid roms I would frequently use 'smartass'. Not sure how it works but I seem to remember reading that it was optimized for those roms. Seemed to work well, anyway...

G2 D800 Lagging, running absurdly slow?

Hi, so I've had my G2 D800 model for a while (about a year or two), and for the most part, it's been an excellent phone despite being 3 years old now. Never had any slowdown problems, and it's always performed well in games and in general.
But just recently, about a week ago, it just started lagging out and being very, very slow.
For example, if I'm watching a YT video through the app, if I rotate the screen, it takes maybe 5-8 seconds to actually rotate. Also, in a lot of circumstances where the keyboard has to pop up, it just freezes the app until the keyboard pops up maybe 10 seconds later.
It's also just laggier in general in most apps, scrolling through FB or Twitter freezes nearly every second when I'm scrolling. It's generally unresponsive and sometimes just freezes outright. It also acts this way on the homescreen, and in most everything else.
The most annoying part, however, is that sometimes the devices just doesn't turn on for sometimes up to 15 seconds after pushing the power button (and it usually just refuses to turn on when using my knock code).
The odd part, however, is that once it's actually in something like a game, it performs perfectly fine.
I've played a number of Cardboard games, as well as games like Nova 3, and it performs perfectly.
I've also ran multiple benchmarks (Geekbench, 3DMark, etc), and it scores around where it should.
Info about the device:
LG G2 D800
Stock Lollipop 5.0.2
Software Ver. D80030f
Kernel Ver. 3.4.0
Rooted
TWRP Recovery installed
XPosed Lollipop installed
G3 Tweaks installed, a number of tweaks applied
Everything else is stock (homescreen, etc)
What I've tried/checked:
Checked memory usage during "lag sessions", rarely dips below 300mb free
Changing minfree values through Rom Toolbox (tried every preset, as well as setting everything to the max to free as much as possible)
Rebooting (affects nothing)
Checked CPU speed with Rom Toolbox (is at max, and does achieve the max speed of 2265 MHz. Setting it to performance mode/setting the min speed to be 2265 MHz has no effect, but reduces battery time)
Changed default cache sizr (tried every preset from 128kb to 4096kb. With multiple benchmarks, the optimal value for r/w bounced between 512kb and 4096kb, currently on 4096)
Things I have not tried (that I am aware would possibly have an affect):
Changing anything in the kernel tweaks/build.prop
Completely wiping, reformatting, and reinstalling (I really would rather avoid this if possible, as it would take a while to get everything back to what it is now, and it was a pain to upgrade to Lollipop in the first place)
I am unaware of anything else I could try to fix it, which is why I'm here
So, does anyone know of any other solutions or things to try? This has made my phone very unreliable, even for phone calls and messages, which is a problem.
Thank you for your time and help!

Hi,
First thing i need you to try out is this custom kernel : http://forum.xda-developers.com/lg-g2/development/lp-5-0-2-kernel-3-4-107-dorimanx-1-0-lg-t3102512
Then install greenify, and hibernate all the unnecessary apps.
This should solve the issue.

Thanks for the quick reply!
I'll try out greenify, though there aren't many unnecessary apps running (i uninstalled all the bloatware first thing, when I rooted).
And about the custom kernel, it's something I've never tried, so I have a couple questions.
Will it wipe my device, or break TWRP, root, or Xposed? (Sorry, didn't see the answer on that forum)
Will a TWRP backup I make be able to fully restore my device to it's current condition?
Is everything that is supported on my device be supported with that kernel? (Apps, etc. Don't know a whole lot about how kernels work, so I don't know)
Thank you!

Hi,
Even you uninstalled bloatware, the apps you use daily could be running in background and taking all those rams. So whenever you play a game or dont use a certain app, just go to greenify and hibernate. Since you have xposed installed, you can do more than that such as u can stop sync , etc.
About the kernel, it has a ram management settings and cron task.
Ram management dont need to be altered. It has some preset profile so if you seek performance, just choose performance or if u need battery , select battery profile etc.
Cron task is useful because it will do alot of things automatically. For example, it will release ram at certain amount of time from the apps , it will restart google play service since that could be an issue , etc.
All you need to do is take a nandroid backup just to be safe. Then download Dorimanx Ota from playstore and it will detect ur device and show u which version of kernel is available. Then download that, go to recovery, flash it, and you will see three app installed : Synapse -- will give you all the details of ur setup including cpu speed, temp etc for monitoring purposes
Dorimanx settings - this is the main settings of the kernel. You will see a P icon on top, tap it and choose your desired profile.
Color management : It is as the title says, just leave it be.
Then use your device, check your ram and report back. Hopefully it will resolve your issue.
Wow. Dorimanx did a lot more than I was expecting.
Downloaded the app, downloaded the kernel, flashed it no problem, went through and checked out synapse.
Went into the Dorimanx settings, and set it to the "Performance" profile.
Immediate improvement.
The whole phone seems a lot more snappy, and I switched back and forth between a 1080p60 YT video, facebook, and twitter with absolutely no problem.
Free memory when idle (no apps open) stays around 1gb; it used to be about 500mb before.
Tested a few games for the heck of it, and it actually seems to have improved game performance somehow. (It seems to have overclocked my CPU to 2.5ghz, though, so that makes sense.)
Temps stayed at around 58-60c while running a few Cardboard apps, so it seems fine.
Thanks for the help iubjaved! This has fixed my issue and then some! Ah, the wonders of the Android dev community.
