[Q] Android System is draining my battery a lot since I updated my phone to Kitkat

Before the update everything was fine. Now if I turn on the screen or listen to music the phone would awake (it would show that it was asleep in jellybean). When I turn off the screen and I am not listening to music then my phone falls asleep. Android system used to be awake under 20 mins over a 15-30 hr span now it can be well over an hour in 4-9 hr span. I did a factory reset yesterday already, uninstalled all of my apps and reinstalled them when I seen that the problem still exist. I googled the problem, but can't find a solution. Is anyone else getting a Android System battery drain like me.

Yes, I am having the same problem. I was told to do a factory reset but I cant even back up my phone with kies because it the MTP driver keeps failing to install and Kies says I have to use Kies 3 even though the Samsung Site says 3 is for the Galaxy Note..
Did you sideload your update or was it OTA?

It was a OTA. I did a factory reset already, but that didn't fix the problem unfortunately.

yeah I side loaded the update and I am on 100% stock no rooting or anything. My phone gets really hot all of a sudden and the battery starts dropping like crazy. I have none of the apps running so I don't know what the problem is..

that is odd. I was reading the forums on the sprint galaxy note 3 update, and people have posted pix of their battery stats. Their stats looks similar to mine. The people there was saying that maybe the problem would fix itself over a week. Im hopping it do, because I am really loving kitkat...minus this issue of course.

oh wow. You definitely have an app that is not liking kitkat. Your phone does not fall asleep when you turn your screen off. Im really trying to figure out why your phone is doing that. Im going to assume that "lookout" and "Malwarebytes Anti-Malware" are the problem. My opinion is that you don't need those as much as you think you do. they are most likely the cause of your drainage. My phone falls asleep as soon as i turn off the screen. Now i have 90% battery life with almost an hr of SOT left, and thats on 4g LTE the entire time.

Heres my stats new stats

I had alot of problems when on wifi, don't use it anymore and sticking with 4g. I'm at 30% left with just over 4 hours screen on. I'm guessing it's something either Google or Samsung have syncing more often on wifi, on wifi I'd be dead at 3 or 4 hours screen on time

Thats interesting. I haven't used my phone on wifi yet, because its a little inconsistent right now. If your phone is acting up while connected to wifi then it got to be something on samsung's end. You can end up with just over 5 and a half hrs of SOT if you stick to 4g and don't want any problems. I would keep testing how things go on both wifi and 4g over the next couple of days if i were you to see if the problems continues though. What problems are you getting while connected to wifi?

Another one of the major problems I am having is that sometimes my apps don't work. When i clicked on the camera it did not show up the app opens but the camera does not turn on. This leads to a major lag and when I try to press the home button it does not work. Then my phone's screen just shuts off and I cant turn it back on via the home button or the power button.
This also leads to the phone getting hot and losing the battery very quickly..
oh and btw the S5 does not seem to impressive to me..

I had the same problem at first. Waited a few days and it still drained badly. Then I went into startups and turned off a few of the apps I never use. Working fine now.

Same problem as the op. Android system would take alot and phone wouldn't sleep. But on 4g it sleeps. Could be an app I have I dunno. 4g is fast here so it's not a problem for me

i reset the phone and didn't install any apps and come to find out that its something that is already on the phone. I had no apps on my phone and android system and android os were in the top three that was taking up a lot of battery.

I recently had an issue with Android OS draining a lot of battery. I read somewhere that disabling stuff from Google sync that you don't use can help, so I disabled sync for all Google services except the ones I use, such as contacts, calendar, app data, people details, and play books. I rebooted and watched my battery for the next couple of days. And it worked. My battery life is a lot better, and Android OS is not using nearly as much battery as it did before. Perhaps this will help you guys?

***UPDATE on HOW TO FIX***
I HAD terrible batt drain with nae.. so bad that i left the device on the charger overnight qnd woke up to 35% batt... i got mad and reflashed stockish v6.. but.. batt drain was the same...
so.. here is what i did... i ended up flashing negalite r6 and the batt was so bad my phone would be dead within 1hr.. SO, FOR KICKS, i reflashed the MK2 modem and HOLY COW!, problem solved!!
im currently on negalite r6 ( a nae rom ) but using the mk2 modem and my batt drain problems are gone. in fact im getting great batt life. i didnt change the kernal or anything. i have flashed ktoonsez kernal over it, and it has not effected batt life at all...
in conclusion, if ur batt life sux, try reflashing mk2 modem.. it worked for me.. and yes 4g, mms, calls, and wifi work without any problem...
hope this helps

I don't even have sync on to help with battery life. Then again i never have it on unless i need to have something pushed to me.

[Q] [SOLVED, kinda] Weird battery drain for no apparent reason

Hello all,
I own an international N9005.
Up until recently, I used the stock Samsung ROM with good battery life.
A couple of weeks ago, with no apparent reason, I started getting horrid battery life - in access of 10% drop -per hour- in idle (as opposed to 1-3%).
I removed more-or-less everything, disabled more-or-less everything but nothing seems to work.
Got root (there goes the warranty) tried looking for Wake-locks and nothing. The Note3 is 97% (!!!) awake even with everything disabled, and in the wake looks screen both user and kernel I only see 1-2 minutes (!).
Tried resetting the ROM, tried installing other custom ROMs (X-Note, Omega, etc). Nothing seems to work.
Currently I'm running Omera v20, with *zero* applications installed (including all the Google and Samsung applications beyond Google Playstore) and all external services (location, WIFI, et-al) disabled, my note 3 is still 95-99% awake, and the list of wake lockers is, errr, empty.
FWIW I'm ~100m from the nearest cell tower.
EDIT: According to battery meter, Android OS is keeping the phone up.
Any ideas?

Indexing your external SD maybe?
You could try the link in my sig and try again for your custom ROM.

First, thanks all for taking the time to answer.
I'm thinking about getting a new battery, but my gut feeling is that its not the source of amazing battery drain - ~20%/h while completely [!] idle (auto-sync/location/etc completely off).
I've attaching /d/wakeup_source in excel format sorted by count and total time - in-case someone has any idea what's completely broken.
As far as I can see, qpnp-vadc-ebd30a00, sec-battery-monitor, mmc0:0001:2 are the main culprits.
nicholaschum,
Before I attempt a complete wipe (as opposed to the normal wipe data / cache), how can I detect if someone is indexing my sdcard? (which may account for the mmc0:0001:2 in the wake lock dump).
- Gilboa

I know this is a long shot but try turning off developer options if you have it turned on(especially force gpu rendering). Somehow I found out that when I turned it on and the screen is idle. I get a battery drain. Not as big as yours. But not really sure because if I use the phone, the battery is actually pretty great(an hour of screen time is about 10% even more with internet apps like facebook youtube chrome etc.).
Clear cache. I know this is too common but it actually works for a lot of people.
Lastly, try airplane mode overnight and see if it doesn't drain. It might be your network that is causing the drain.

Hi, basically just check your phone using BBS (BetterBatteryStats), and see which individual process is eating up your battery.

Already installed - together with WakeLockDetector.
Short update, out of pure desperation I completely wiped the phone (including sdcard), tried installing stock ROM and, err, Odin failed. Managed to get CWM running again and installed the latest CM nightly.
...
As weird as it sounds, going from NF4 based ROMs (including stock) to CM nightly dropped to idle battery usage to ~2-6%/h, a huge drop from ~20%/h.
I'll update and mark resolved if this situation holds (crosses fingers).

I heard there were problems with NF4 battery. But I haven't been on TW since ND4. No matter what on Note 3 TW the battery sucks. AOSP is great. But actually S5 port has the best battery.

Solved, at least for now.

I use Nova (and not TW)
Either way, latest nightly seems to solve the battery drain problem completely - using the same Nova and system configuration (widgets, active syncs, etc). Currently I'm at ~1.5-0.8%/h when idle with no issues going into deep sleep.
Seems that my specific model really dislikes NF4.
Thanks again for trying to help.

This thread has been quite helpful as I was suffering with a Battery Drain after the NF4 Upgrade.
Planning to go back to ND5, which was the last stable version.

I was thinking about doing the same, but in the CM 11 runs circles around both NF4 (duh!) and my previous ROM (not sure which revision it was) - plus I can actually get 2 days of standby time, even with the old batteries, so I'll stick with CM 11 for now.

GApps on Rooted LG V20

Does anybody know if we are able to flash any other versions of GApps on the rooted LG V20?
My V20 is from AT&T and since day one it has had terrible battery life. Where I was able to use my Note7 or Droid Turbo all day and still have battery left, the V20 eats the battery charge like Sally Struthers in a See's Candy warehouse. I mean, I have to charge this thing at least 2 times a day when I use it to search the web or any battery intensive purposes. I never had this problem on any other phone. I have been trying to find ways to improve my battery. I used Rom Toolbox Pro to disable all kinds of stuff, and it worked great, until my phone started Grand Mal seizing giving me the Google Play Services has to close notifications, which I then had to factory reset just to get my phone working properly again.
I would like to try flashing a minimal version of GApps that pretty much just has the play store and play store services. Are we able to do this on our V20's without having any issues? If you have any input at all I would really appreciate it.

IMHO it must be an app or two you have installed draining your battery like that. On a full charge I can a whole day and a little in to the next. I am a heavy user too. Are you blasting the brightness at 100% all the time? If so auto brightness will help a little. Go in to setting and see what is using that much drain

I was thinking it might be something I installed, as well. But I can't seem to pinpoint any apps that might be causing the battery drain. I keep the screen on auto brightness like you mentioned so it shouldn't be the screen. GSam almost always shows the Android System and Kernel (Android OS) at the top of the list of battery-draining apps. I love the phone, I just cannot figure out what is going on. I mean, I am not doing anything different than I have on my previous phones, and the V20 seems to be working fine. I thought maybe it is something with Nougat. I will gladly post some pics of app usage or data if it might help figure this problem out.

What rom are you on? Are you on stock white theme? I'm running a dark theme, which can help save a little juice. I'm also running as many team blackout apps as I can (many Google apps) to avoid all the whiteness. Just throwing out some ideas.

Interesting! I have never heard of Team Blackout Apps, they look pretty nice! Yes, I am on the stock ROM just the way it comes. I haven't changed anything at all. I have barely installed any apps just to see if I can find what is causing the battery to drain. Are there any other ROMs that work with the AT&T variant of the LG V20? It seems like they haven't made any yet for the AT&T V20. I am still waiting for Xposed to be released that is compatible with nougat so I can use Amplify.

I don't think there are any roms for AT&T variant atm. I did see an AT&T user flashed the stock deodexed rom by tilde88 in rom section. Not sure of all the details though. I'm assuming you would lose some functionality...would need to flash stock kernel as well.

What is your leading source of battery drain under system usage?

Yeah definitely, I think it is a little bit too early, for me at least, to expetiment with a deodexed ROM. But I know there will be some awesome developments coming out soon. I was so happy to see that a root was figured out for the V20 so quickly after it was released. Until then, I will keep experimenting with the stock ROM.

Hi Swizzle82, thank you for the reply. It is kind of difficult for me to pinpoint what the leading source of battery drain is because the apps seem to bunch all detected processes and wakelocks together. I know that Call Services & Android System show up on top a lot of the time, but since I factory reset the phone today, the stats are minimal compared to what I previously had. WeChat also uses resources, but I used that app all the time on my Note7 and previous phones, even more than I do now, and it never caused a problem. I attached some screenshots from GSam, BetterBatteryStats, Wakelock Detector, and CPU Spy Reloaded., I don't know if they will help, but just switching between those few apps and taking some screenshots over the span of 6 minutes, my battery percentage dropped from 79% to 76%.

I had android system for a while killing me.. I factory reset and setup every app one by one with no data transfer or anything. Installed every app like it's first install. I charged it til it reached 100 percent, with the phone plugged in, I went to data/system/batterystars.bin and deleted that file and rebooted. It was a long process but it hasn't been an issue since. This was when the phone first came out last month. Never knew which apps data it was but it is gone now.

That sounds like a good idea to try. I will do this today since I already factory reset it yesterday. I would rather do it now before I get further into using it again. I have not heard about this until you mentioned it so maybe there is an issue with app transfers with the V20 causing it. The battery does seem to drain less than before, but it seems like there are still some issues. Thank you for the suggestion!

If you followed did the dirtysanta method, make sure you flash the Konverged kernel for the H918. Or Tilde88's 5.1 kernel for the H918. It worked wonders on improving battery life. Also make sure you disable Lookout - that drains a lot of battery it seemed to me at least. I usually get about a day and a half of battery life when I use my normal amount (which is honestly quite a bit).

Okay, thanks for letting me know! I have not even looked at those kernels thinking they weren't cross compatible with H910. I am going to try it right now with the dirtysanta method. I will disable Lookout, as well. There are a ton of apps that I never use that drain the battery. I will let you know how it goes :good:

No, I had the Note7 before getting the LG V20. Before that I had a Note 4 and a Droid Turbo. This is my first LG phone and I really do love it. I actually like it more than the Note7, the only problem I have is the battery. I do think that factory resetting and manually installing the apps instead of restoring them will help, and using the Konverged kernel seems promising, from what I am reading.

Yup I always start fresh and install apps manually anytime I reset my phone. I think it's always nice to start fresh - even if it is sometimes a bit inconvenient to go through all the apps you've installed and choosing which ones to install. Hopefully you get it all sorted out!

I had android system for a while killing me.. I factory reset and setup every app one by one with no data transfer or anything. Installed every app like it's first install. I charged it til it reached 100 percent, with the phone plugged in, I went to data/system/batterystars.bin and deleted that file and rebooted. It was a long process but it hasn't been an issue since. This was when the phone first came out last month. Never knew which apps data it was but it is gone now.

Okay, I just factory reset the phone, rooted it with DirtySanta, and flashed the Konverged kernel and the phone is NOTICEABLY faster and smoother! This is great! Each time I reset the phone, it had noticeable lag. I just figured it would go away over time, which it did, and that it was because it had to load and download everything since it was fresh. But with the Konverged kernel, it has none of the lag and is silky smooth! Time to manually install the apps I want and disable some stuff I don't need. I will update you guys after I see how the battery is with the new setup Thanks a lot for your help, I really appreciate all the input!:good:

I need your help! I changed the screen cover sensor to off not realizing that I would not be able to turn off the static after rebooting my phone since the sensor is off. Would somebody please post a few screenshots showing how to navigate to the screen sensor settings so I can tap my way there and turn it back on? I am trying but there is no way to tell where to tap with all the static. Thank you!
Nevermind, I fixed it! I finally navigated to the second screen settings and turned it off when the screen is off and that got rid of the static after I turned the screen off then on again. Note to self, never do that again LOL.

Wow I'm fairly impressed you managed to do all that with the static screen haha - glad to hear it worked out for you in the end.

Get me your stock system.img and boot.img, and I'll make you a modded ROM with a custom kernel!

Haha yeah, I never knew something like that could cause such a huge problem. Now I can't seem to find what I did to cause that in the first place. I have been looking through all of the settings and can't seem to find anything that affects the proximity sensor. On top of that, the screen rotation stopped working, it will not rotate when I turn the phone to the side to type. I have toggled all of the motion and second screen settings, calibrated the motion sensor, and nothing is affecting it. When I turn the main screen off, the sensor does not shut off the second screen when I cover it with my finger, and the phone does not recognize when I rotate the screen. I am kind of at a loss on how to fix it.

Android 7 update made my phone very slow. I am looking on the return policy now

I updated my ZTE Axon 7 to Android 7 and I started hating the mobile.
Issues:
1. Finger print recognition is not perfect.
2. whatsapp is very slow - especially - taking and photo and sending it.
3. phone is deadslow most of the time. i.e. I have to click on some apps and wait for sometime, some cases it closes automatically.
Is there a way to go back to Android 6 or What is the return policy. I bought the phone 1.5 months back in Amazon.
I am really frustrated with this thing and I need to get rid of it.

I am with you on this...same happened to me also.
Phone is too slow, fingerprint is not identifying the print accurately and its too slow, whtasapp is a disaster.
Apps opens too slow.

Same issues here...
I read in the ZTE Forum that a couple people have gone back to MM with the file from the ZTE support website but I am not sure if I want to do that ... or wait a couple days so ZTE will HOPEFULLY come up with a hotfix...
There are a lot of other issues also like verizon SIM is not recognized at all, fingerprint issue, battery drain, slow animations, performance over all....

You may need to move to LineageOS
what aboutLineageOS?
https://forum.xda-developers.com/axon-7/development/unofficial-lineageos-14-1-zte-axon-7-t3545679

+1 all issues mentioned by original poster, I don't know if ZTE actually QC this release or not ? The whole performance is abysmal after update.

You're not allowed to return it

So I've done full factory resets twice, cleared cache, etc. My phone is still about half of what it was on 6.0. Fingerprint reader is what is killing it for me.

+1 I feel this phone is so slow. Is it under clocked? I came from a Zenfone 2 running an Intel x86 and it never lagged. This phone seems so laggy with scrolling, apps etc. Feel a bit disappointed. Is it the Nougat update? Thanks.
Sent from my ZTE A2017U using Tapatalk

My phone has definately lagged a bit sometimes but its been working fine otherwise after the Nougat update. I did a factory wipe and my phone isnt rooted.

Just a thought, don't know for sure, but you should head over to this thread see if this helps you any

I've done the same thing. Factory reset 6 times and I've also cleared cache numerous times. I've tried a few things because I also had random restarts that would happen from once every 15 minutes to once every few hours and sometimes not turn back on or get stuck in deep sleep. So far as of now I've tried a few tweaks that seems to have sped up nougat substantially. The auto powers are mode seems to be bugged off the bat with nougat. I've been running in performance mode and have gotten better battery life than in auto mode. Also speed is increased and my restart issue has disappeared thus far. If I were you I'd just tweak the settings and give it a few days. After talking with zte support, they are under helpful and both return options for replacement are obscene at best.

Yeah, I've done all of those. Nothing seems to help. Facebook app still unusable, fingerprint reader only works about 1 out of 5 times, even after setting up multiple fingers, etc.... I am not a happy person. My phone is completely stock, too. I was laying off doing anything custom to it because of 7.0. Apparently that was a mistake.

Yeh after looking online it seems that almost every phone that got updated to nougat had a plethora of issues until hot fixes were issued. Even the nexus 5x had issues. Seems zte only made sure it kinda worked and then released it because people kept batching about the delay of initial rollout.

BUGS & BATTERY USAGE on JULY official rom

hi MI A1 owners.
for those brave enough to use the latest vanilla, official OTA rom, what change did you notice?
does the battery still suffer huge drain that appeared in 2018 roms?
it's a big "NOPE" for me to update, i'm still on official DEC rom because of this drain issue.

Battery life is good on 8.1 no issue for me getting 5-6 hours SOT on gaming.

Never had battery drain problems. Only "issue" is notification led not blinking.

Just noticed that led light is no longer blinking when notifications arrive. Light stays on only when screen is off. Also Bluetooth is constantly disconnecting.

Ambient display isn't working for me.
Led notifier is also not blinking anymore!

Led not blinking, proximity sensor doesn't work properly all the time, some scrolling lag. That's what I've got so far

dudes thanks for your answers.
i'm just more convinced to not doing the update.
maybe the drain i had was magisk-related. (?)

Nothing for me, even got ten hours of screen after some cycles. Led doesn't bother me and it's the only thing i noticed.

Yes, the LED is always on, which is annoying, but the bigger issue is there is no change in the battery drain. I charged to 100%, set the phone down and did not move it or use it overnight. 8 hours later almost 14% of battery was drained. I have tried everything I can think of to try, including turning off high accuracy location, not allowing any location things like safe area, etc. and still I get this drain even when the phone is not in use. Android kernel and system consumed 85% of that usage, and System UI, Play Store and Phone Services accounted for 7%! SO basically, basic Android paired with the A1 hardware seems to be the issue and I don't know that there is any fix for that.
At one point, I thought an upgrade to the A2 was going to be a no brainer, but with the issues with updates being broken and this battery drain issue that nobody seems to be able to pinpoint and resolve, I am thinking I may not buy ANY other Xiaomi. It may be time to try something else because the only way I can get two days of battery is to turn on airplane mode when the phone is not in use!

Dunno what to say man. Mine is below.
2-3% at most over night.

And now it would appear that there is an issue with airplane mode.
I put the phone into Airplane mode at 2300 last night with 90% battery and did not pay attention to it. This morning I turned to phone on to find there was only 69% battery left, and WiFi was working. (see screen shot) WTF???? I have started using airplane mode to keep the battery drain to a minimum when the phone is not in use, and now it would appear that this doesn't work either.
I am REALLY getting frustrated with Android and Xiaomi as it seems that every time they do an update, something else goes bump! I have gone from totally happy with the AI when I first got it to being ready to write off Xiaomi as a company I would consider for purchase.

Play services also cause these type of sudden battery losses.
Try downloading latest play services apk from apkmirror . Latest one is
"com.google.android.gms_12.8.74_(090408-204998136)-12874034_minAPI26(arm64-v8a,armeabi-v7a)(480dpi)_apkmirror.com.apk"

Thanks for the thoughts, but unless I totally misunderstand what airplane mode is, WiFi should not be active when airplane mode is invoked. You can see by the screen cap that airplane mode is on AND WiFi is active. This seems to be a one off as it has not happened again for the last two days. I turn airplane mode on to stop the overnight battery drain while the phone is doing nothing. I have location set to GPS Only. IIRC play services was just updated 3 days or so ago, so it should have the latest version. I will check it and see though. Again, thanks for the thoughts.

I can't logically understand why you would think it is the hardware causing the issue. If it was hardware, what you are seeing would be happening to every owner of the phone and clearly that is not happening. By saying it is the hardware when you have other software loaded is akin to saying your car's air conditioning doesn't work properly when you have all the windows wound down.
There is something loaded on your phone that is causing the systemUI to be working when you think nothing should be happening. The first thing I see on the screenshot on your phone is that in the top left of the screen you have two non standard icons. That tells me that you have a skin or non standard software constantly running.
The way to solve any issue like this is to go back to basics. I would get the fresh rom and do a Miflash whilst keeping your data. Make sure you do a backup first.
If that does not work, back up your data and do a clean install and check the phone's battery life. Do not load any non google software / app at this stage.
Then each day add one app and test for 24 hours. You will find this issue and the offending app or apps and I would be willing to bet you a few Singhas it will be an app you downloaded not the hardware causing this.

Actually, I think it is a combination of hardware/software, but that is just a WAG. Others have noted the exact same issue without running the same software. My bet would be on the RCS services stuff.

Those icons are my Email client and GSAM Battery Monitor (presently 0.1% and 0.8%) and are the only two constantly running programs other than the stock apps and Sophos (0.3%). Neither use much battery compared to the Android stuff. Presently Kernel is 41.6%, RCS/Phone is 30.3%. SystemUI is 3.3%, Play Services is 2.0% and Phone Services is 1.8%

Good advice. I will do this when I have a few days to play with it. In the interim, it's airplane mode every night. Thanks for the reply. If it turns out to be one of these apps, let me know where to send the Singhas.

Good luck with it. I hope you find the solution. It can be frustrating, but getting to the bottom of it will be worthwhile. I haven't used Sophos for a long time and even then it was for PC. I am not up with how Sophos AV is integrating into Android but that would be my first guess.
I have only had one issue with this phone after updating and it was that the OS was constantly asking for a password on unlock after using fingerprint not just on startup. A clean install solved it and I have been trouble free since with every update. With over 50 PCs in my office, I could only wish that I had so few issues with Windows updates as I do with Android.

For me, night light auto schedule not working properly.

I can't tether via wifi/bluetoth/usb
Made another post with the problem.

Just for grins and giggles, I uninstalled my email client, GSAM, and Sophos, the only programs that run constantly other than system and Line. I then turned my phone off and back on, forced stopped Line, charged it to 100% and set it down with the screen off. It did not move of get used for 8 hours, yet it still used 12% of the battery. (see screenshots) This is better than the 20% with those apps installed, but still not close to what I would consider normal. When I first got the phone, it easily lasted 2-3 days between charges, with 6-7 hours SoT. Overnight would use MAYBE 2% of the battery. Now if I want it to last 2 days I need to turn on airplane mode overnight and then I can make it through a day.
So I guess the next step is to do as you recommended and load up the fresh rom when I have time to mess with it. At least I am now pretty sure that those apps aren't the culprits causing the biggest part of the battery drain. I hate to do it, but I am seriously thinking of a factory reset and seeing if that clears the issue. Would that put me back to Nougat?

So those apps were causing 40% of of the 20% of the battery drain. That is a good start. I am confident there are software issues with your phone. I see you have some GPS app on your home screen, if that was running askew, it might be constantly pinging. That is just a guess.
In things like this, work methodically through it. But of cause a hard reset would be the best way to go. I see no reason why you wouldn't stay on your current version after a hard reset.
If you want to go make to version 7 you would need to use the MiFlash program and a downloaded standard fastboot rom. You may need to do something else to the phone to go back to 7, but I would not think so.
