[SGT7+CM10+Cherry Picks,By meghd00t] Battery Drain - Barnes & Noble Nook Tablet

flashed the new update 24/9 and having horrible battery drain. The problem is the tablet is not going into 'deep sleep'. Has anyone else experienced this??

I'm not positive which one of these is what makes it actually deep sleep, but I've done the following:
Disable syncing
Enable the HOTPLUG governor
Power off device, then power on (Power off, not reboot!)
Now, deep sleep is working for me mostly. Sometimes it seems that some process will still get hung up and prevent deep sleeping so it's likely there are other issues going on.

i think he means apps that sync data. like your google account, dropbox, facebook, etc...
basically apps that use the internet to update stuff.

I use this ROM 27/09 two days and I'm very happy with this. The first time when I used, the ROM battery rain fast, it does not come to deep sleep, and I heard that change the governor to hot plug is the way that tablet can, but change the governor make more frequently the tablet get SOD. So that I installed set cpu, I set the profile screen off min 300, max 800 the governor hot plug, the main profile I set min 300, max 1200 governor onderman. I still have not any SODs up to now, very happy with this.

I've been getting one or two SODs a day using hot plug so I am going to try set cpu and see how it works. Thanks.
Edit: Using SetCPU per your recommendation, in the last 48 hours I've had a single SOD, so it seems like you're definitely onto something here. Thanks again.

no more battery drain on build 12/10
Hi, I tried with build 12/10 and no more battery drain.
The only thing that I don't know how to work is the OTA Updater, it showed the new update, but everytime NT restart it will fail, and back to previous, like nothing happened.

I started with 10/12 build (12/10 for those who use dd/mm) and battery drain seemed to be about what it was when I had the Nook simply rooted. It my be a lil higher, but I used it a lot for games and web surfing. Just updated to 10/25, will see how the battery drain goes, if it's similar, different, what not.

I just used the OTA Updater, and the only odd thing I had to do manually was during the reboot, I had to set the loader to boot to Recovery EMMC, after that it updated automatically and upgrading without issue. Also, prior to the 10/25 update, OTA Updater was saying the 10/12 version was also the update, therefore you were trying to load the same version.

Well, after some time I've already noticed significant battery drain that wasn't present in 10/12, especially when putting it to sleep.

No issues waking up, just a lot of battery drain while sleeping. That's been the only issue. Though I haven't had any SD card issues like i did with 12/10.

Too funny! I have just the opposite. Zero drain while sleeping and SD remounting when it wakes up.

Update: Booted into recovery (CWM 6.0.1.4). Cleared cache partition and dalvik cache, then reflashed 25/10 and gapps. Battery drain during sleep seems to have gone away. 0% drain while asleep for 90 minutes. Yesterday it drained 13% in same amount of time. Will continue to observe.
10/31 Update: After charging to full then unplugging and letting it sit all day in sleep mode, it nearly fully discharged (down to 11%). So I guess I'll try to roll it back to 12/10 and see if things improve.
10/31 Update 2: Rolled back to 12/10, fully charged, then left alone in sleep mode for 5 hours resulting in only a 2% power loss, far more acceptable. Guess I'll just stick with 12/10 for now.

Well, Due to constant issues with SD not remounting, I decided to move on to CM10.1. Well, that and it's got some new bells and whistles, even though it's still WiP.

The SD unmounting is a known bug with an easy work-around -- and I think it may be related to the kernel, so changing to CM10.1 may not fix that for you... As long as you turn off WiFi before your tablet sleeps (easily done with AutomateIt) you should not see any problems. I've been running the 28/11 version of the ROM for nearly 3 weeks now with no SOD or random reboot problem... Deep sleep is working fine as well without any tweaking. This is far and away the most stable ROM I've used for the NT.
With that said, I'm probably going to test drive one of the 4.2 ROMs this week as well. Hopefully demetris will update this ROM to 4.2 eventually.

[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.

Cm7 - horribly battery - i don't think its cm7

i'VE BEEN RUNNING CM7 for a month (about)
I update to the latest version and right now im on the KANGED version thats not OFFICIAL release but it is made by the dev.
Anyways...
Every day i wake up in the morning, from 100% my battery goes to about 90- 85% from using it then i go to school, phone in my pocket for about 7-8 hours.
It usually goes to 70% or 75% when i check soon as school is over.... but today.. it was at 32%!!?
My battery has been draining FAST this past week. IDK what's causing it, but i think its a app, but watchdog lite doesn't show anything at all.
Any tips at all guys?
- PLEASE DO NOT REPLY TELLING ME TO PUT IT ON AIRPLANE MODE WHILE IN MY POCKET- I GET TEXTS FROM MY BROTHER/MOM TELLING ME IF I HAVE TO WALK OR IF THEIR GOING TO PICK ME UP AND OTHER IMPORTANT INFO LIKE THAT-
Please help me out here.
I love CM7, and it's NEVER been this bad, but if it is because of CM7 then i have no choice but to go back to 2.2.1
EXTRA INFO:
I don't have a data plan so... my phone can't communicate with other servers and crap.
I keep wifi off, bluetooth off GPS off.
Maybe i'll have auto brightness on but thats it.

try recalibrating the batter by using either root explorer or the terminal to delete /data/system/battstats.bin as sometimes CWM on cm7 for galaxy s doesn't delete it.

try not using the battery claibrator app, and removing it from your phone and manually deleting the batterystats.bin file from /data/system and see if that helps your phone at all.
I also suggest getting CPUSpy from the market, and track what states your phone is in and for how long it is in certain states. if it's not going into the sleep state, then something is keeping the cpu active (possibly a governor setting).

That aint normal my friend, you should jump into another modem, regardless of what you're on. Maybe that helps and by all means, what kernel are you on?

The stock one should be battery efficient but I honestly haven't really tried it out. Give r12 or r25 a shot from here. They've been great in every aspect to me. Just make sure you're not on kang 7.1 when flashing, it doesn't support that.
As for modems I'd suggest either KB5 or KB1. If you're on either one switch to the other, may help.
don't run phone on "performance" -- it's silly to run the cpu at top speed when the phone is just sitting doing nothing. Run it at "on demand" or "conservative" especially if it is OCed. Also set screen timeout at a minute or less. If you got the phone used, it's possible the battery is old. If you reboot it a lot and install roms and stuff you'll run the battery down fast.
Well..
Yesterday I did a cleaning of apps i never use and some i installed recently.
I guess that did the trick? I have no more problems came back from school and my battery's at 76%
@Abu, thanks for the tips. i don't want to get a different kernel and modem.. im on kanged 7.1 lol.

don't use setcpu if you don't have to. the built int scaler for the kernel is actually much better than letting setcpu run in the background polling the cpu and system for changes.
if you're running a custom kernel, get voltage control, and with it you can UV, OC, under clock, and change scheduler.
And in Settings -> CM Settings -> Performance -> CPU Settings, you can control min frequency, max frequency, and governors.

[Q] "Suspend" + "Events/0" Processes Draining Battery?

Hi guys,
So for the past week or so, I've been noticing really bad battery drain on my GS2, and I think I have finally pinpointed the problem.
"BetterBatteryStats" has told me that there are 2 specific wakelocks running in the background, which prevent the phone from going to 'deep-sleep'. These are the "suspend" and "events/0" processes. They are on for hours, preventing the phone from going into a proper 'deep-sleep', and keeping it awake.
My question is, how would I stop these processes from running? I know for a fact that it is not such a common 'bug', because tons of people are getting >18 hours on their GS2 with moderate/heavy use, while I'm only getting about 10 with light/moderate usage.
So in short, why are the "suspend" and "events/0" processes running while the phone is supposed to be in sleep mode, and how do I stop them from running and draining battery?
Thanks everyone!
Well I don't have that problem so can't say. You should ask it on the BBS dedicated thread,

This is the famous "Android OS" bug, which happens only on SGS2. Search the forum and you'll see quite a few threads about it. There is no solution, but keeping wifi off when not in use or setting is to sleep when screen is off helps quite a bit.

well for me, installing the siyah 1.8 kernel has sorted it and my battery life is pretty damn good now.
Others will tell you its not fixed and the extra battery life im getting is a placebo. But all i know is i used to get 3 hours screen on time and lose 15-20% battery overnight. Now i lose 2% overnight and get 5-6 hours screen on time. If thats placebo then so be it.

hmm, ok, I will look into kernels, I am using an AT&T SGS2 so its a little different kernel wise. I have yet to find anything in my specific forums though.. just switched from an eperimental kernel to a stable, so maybe this will help
I think I just read somewhere in the Galaxy S2 forum that AOS isn't exactly solved on the .14 kernel (which siyah 1.8 is based on)..... it just merely not include suspend and events/0 into the Android OS count for the battery.....
Anyone can shed some light on this?

is siyah 1.8 better for battery life compared to siyah 2.1 or the newer one?
I tried 2.1, but I still have high android OS.
Using bbs, I see that suspend and events/0 is still around 1 to 3 minutes each day.
I have turned off:
Accounts and sync > background data & auto-sync,
Privacy > back up my data,
Location and sec > use wireless networks.
Any other advice?

Use a 2.3.4/2.3.5 based ROM such as CheckROM HD or Hyperdroid-Androidmeda with Darknight-Siyah Kernel.
I get 3 days of use if i keep data off . With Data on and normal usage i get on average 0.7-1% drop per hour compared to 3-4% of 2.3.3 ROM.I think it's a combination of kernel and ROM that solves the problem.
Earlier CPU Spy used to show lots of time spent at 800Mhz which is what android OS bug does. Now i see it spending 1-2% time in 800Mhz and most of time in deep sleep.
thanks for the reply.
now I am using CRv3.1.1 with speedmod 18test3.
but it seems that from day to day, events/0 & suspend are getting bigger and bigger.
do you know why?
I upgraded to KI3 a long time ago, and froze the hubs + wifi sharing / wifi sharing manager (i never even used the hubs anyways), and what do you know; my battery can now easily last me a LONG time, after 16 hours it still always has AT LEAST 40% remaining, and that is with a few hours screen-on time, data sometimes on, wifi usually always on! I'm extremely happy now!
So in short, for those of you with bad battery life, the least you could do is upgrade to XXKI3 or XXKI4 (they're pretty much the same thing) firmware/kernel. Even completely stock without root/frozen apps is A LOT better than any other 2.3.4 / 2.3.3 ROMs.
CRv3.1.1 is already based on xxkj3, and I have already frozen most of samsung bloatware.
However, I have just found out that kernel is an important factor in high suspends and events/0.
Now I use the previous version: speedmod 17 test 1, and suspends & events/0 decrease a lot.

Houston we have a problem ICS reboot fix killed my battery overnight while sleeping

Yes my Prime went from 40% battery life to totally dead when I woke up this morning....... I knew when they finally found a fix for the lockup issue they would screw everyone else over somehow this is last straw I am returning this once and for all.
EDIT: This appears to have been a one time thing I have tested the battery with sleep since this happened this morning and everything appears to be just fine..... also my antutu benchmark scores even went up a little
EDIT: Well nevermind my battery life sucks drains 40% in 2 hours at 25% brightness just browsing the web my Wi-Fi also randomly now disconnects and I have to click in to network settings and all of a sudden it will reconnect. I want 1.11 back or my money back for the Prime.

o which source are you referring to. A thread here on the forum?
um you shouldn't b jumping to conclusions, in my experience it is not unusual to have crap battery life after a firmware upgrade, aspecially if you have a lot of apps, it has to rebuild caches and all that, so usualy sorts it self out after a couple of days.
The other thing is we can't see what apps could be causing battery drain as Asus hasn't enabled it yet.

Jumping to conclusions? I have never woke up in the morning to turn my Prime on and find it was turned off because the battery had died I think that's as conclusive as can be.

That's not necessarily true, sometimes a broken app, incompatible app, or apps that crashed can keep the processor running. When I first got my galaxy sII the battery drains like crazy. But after a factory reset it was 100 times better. I wouldn't jump straight to conclusion with a one time thing. After all, pics, quad core are still new.

BUT if only 1 thing changed, the OTA update, you can rule that logic out. If he got the OTA update AND changed a bunch of stuff that is possible. As I read it, only change is OTA update and thus, you can start to narrow down the cause.

The system update is not draining the battery life at all, if anything the way the system ha been adjusted to utilize the cores, it should save some battery life. battery drain is caused by an app running in the background, tat is probably not closing properly. Check to see if anything is running in the background, or maybe an app that you recently installed is not working properly. My battery can go a day without needed to be recharged, and this is with heavy gaming/app usage, as well as other prime owners whom have updated. Please try to root out another cause of the problem before just assuming its due to the update.

Yes it did, and mine and hundreds of other owners have not had any battery issue, so I don't see it causing battery issues for some and not others. Have you recently installed any new apps/games? Did you try a fresh reboot? I'm not calling you a liar, I'm just saying check for other possible causes. The speed of the cores have been adjusted somewhat with the new update to help save battery life. Use the link provided a few posts above to see whats running and using the most battery on your device..I bet that's what is killing yuor battery
Well if this is true mine should be off when I get home since i haven't used it since last night. We'll see.
Oddly enough, I had a battery issue yesterday as well - but I have not received OTA .13, my Prime is on 11.1
I left my tablet in my work bag most of the day, in sleep mode. Around 4 PM I go to use it, and it is AMAZINGLY warm/hot, and the battery is dead. I cannot remember what I was using the night before, but something made the processor churn all day, and eventually kill the battery.
I think I did leave it on Performance mode - but can't for the life of me think what could have caused this to happen.
I know - not very helpful as I am not on .13 - but just pointing out yours could have been a fluke.
Charged when I got home last night - and all seems fine today.......

Exactly, this just means that your Prime was *working* constantly, which means that there was an app/game that was running constantly without your knowledge. try a fresh reboot and see if that helps, also, try to find the culprit which is causing your prime to stay active.

You wouldn't be the first one to complain about the sleep mode battery drain on 11.1. I am also quite sure that the .13 version is heavily based on that 11.1 beta.

Holy hell Batman at the Battery Drain!

Is anyone else getting Android OS around 50-60% battery use?
I have tried every ROM included going back to stock. I have ran the phone with nothing but Stock and no apps installed for a day and still get the same drain so I can only assume its a kernel issue.
I am not familiar with LG products in the slightest, but I had a yellow screen of death the other day...something I have never seen in my years with samsung android products. Anyone have any idea what this is maybe it is pointing to a hardware issue?
LG made a great phone, but I don't think I will keep it much longer. Locked boot loaders, no sources, and history of terrible updates have me regretting purchasing this phone. I tried my hand at building a working jb release when I first got the phone and it is going to take a skill set I do not have and I hate waiting on a company to do what they've never done in the past..

Easy, brother. I have only had one of my apps/utilities run higher than AndroidOS ever on this phone; however, that said, I think there is a problem with the way it's being calculated. I'm getting really good battery life with good sleep and still AndroidOS shows the highest by far. I know that's abnormal for it to be so high and still get good battery life, but it is what it is.
Edit: you've installed the fast dormancy toggle, right? As for the yellow screen, I've seen it once in my two months with the phone, just rebooted and carried on. Forgot what they said it was...but it is here in this forum somewhere.

I was just about to post something similar. Andriod OS being high kind of makes sense if nothing else is using the battery, although you would expect that number to fall significantly with increased screen on time and heavy app usage, which it doesn't ever seem to.
I've been having horrible battery drain lately. I'm currently traveling for business, and just use my OG for web surfing and stuff when I'm in my hotel. I leave the phone in airplane mode, with WiFi on. About two weeks ago, when I was on The Base 0.4 in that same configuration, my battery would drain maybe 1% an hour while I was sleeping.
Recently I've been on The Base 0.7.3, and my battery drains over 5% an hour while I'm sleeping. This means no screen on, no apps running, and even turning WiFi off! How does it use that much battery when it's not doing anything? Now, I'm not entirely sure what kernel I'm running. The first time I installed The Base 0.7.3 I used sk8's kernel. After getting poor battery life, I reflashed 0.7 and 0.7.3, this time choosing the freegee kernel. I'm not actually sure if the kernel changed though.
Anyway, I think I'll post again tomorrow with some screenshots from Better Battery Stats+ and CPU Spy.
I'm wondering if this recent botched update had the battery fixes we need. Hopefully they'll re-release it soon.

When I would get bad drain, which has happened several times, I could narrow it down to a couple things in order to solve the problem.
In my case it would always happen after installing Google+. Uninstall and reboot would usually fix the issue. If I got drain on a fresh install without g+ installed, I found that if I installed the 2.2 kernel separately as a stand alone zip, that would fix it. Don't know why but it may work for you too.
I don't have screen shots, but today I recharged at 38% after 3:10 of phone use and 1:55 screen on time and about 15 hours off charger. That's with Wi-Fi on the whole time and Bluetooth for about 9 hours. I have my work exchange account on active sync with push notifications. Facebook and Twitterer to 4 hour intervals. I'm underclocked to 1350 and using powersave gov with deadline.

Believe you are correct. There were issues on the Samsung Infuse and even the international SGS3 for a while... it was referred to as 'memory leak.' Has been worked out by devs on XDA. You can put memory leak in the XDA search above... it's above my pay grade.
Edit: It's great to see another RD here... hope you will reconsider keeping the phone and stay !!

Thanks for pointing me in the right direction. I have Google+ uninstalled, but part of me thinks Google Now may be partially the culprit (although why that would be the case with all radios off, I don't know).
I'll try a fresh install of the 2.2 kernel and see if that helps. Thanks.
I can't speak for anyone else but FDT did wonders for my battery life. I was only able to go about 12 hours prior to disabling FD.

I would be less inclined to believe it is a faulty measure if we had a different ROM not built off stock (AOKP/CM10) that could produce different values. However, I seriously doubt anything built into either of the two custom ROM's is geared toward normalizing that reading. That's why they are both the same as the stock AndroidOS percentages. Jivy is probably right that it's a kernel issue. With the size battery we have, imagine the potential if it is a true reading (androidOS out-of-control) and we can get it under control down the road. We're talking double the current best battery life you've ever had on this phone at the very least.

Get BetterBatteryStats, select Since unplugged and Alarms to see what is waking the device (making it not go into a deep sleep). eBay was a big culprit for me.
The wakelock that keeps the phone awake during background data transfer (screen off) lasts 6 seconds (I am guessing it does it in multiples of 6s) regardless of how long the sync takes. Everytime email, facebook, gmail, drive, picasa, twitter, g+, google maps, ebay, calendar, contacts.. whatever wakes the phone to check something, it will be a minimum of 6 seconds.. This adds up over the course of the day and it is counted in the Android OS. Shut down syncs you don't absolutely want/need and this number will go down. All phones with the Snapdragon S4 Pro has it, especially the Nexus4. It seems they've done some kernel work to fix/reduce it but I havent really looked into it since I don't have that phone. I've seen complaints in the Droid DNA forum as well.
