I actually think there may have been some improvements to battery life. I ended up flashing back to stock last night and then accepting the update. I used Google to restore all of my apps including 5 games that each require more than 1GB extra files. Knowing that it would take a while I just went to bed and when I woke up in the morning, all of my apps and additional files just finished downloading. I went to bed with 88% left and my N7 was only down to 73% even with 6 straight hours of downloading. Not bad at all!

In regards to smoothness. It's so hard to tell. It feels smooth but I have no point of comparison that I can prove.
[Nexus 7 General] Chaw Rash:
Guys what about the flickering issue? Is it gone?
[Nexus 7 General] knuckles1978:
No, there were millions of them!!! I used to love those security updates, all the new functionality they added - don't get hacked - don't get hacked - don't get hacked..Awesome...

God, where were you man when "MS12-074: Security update for the .NET Framework 2.0 Service Pack 2 on Windows XP and Windows Server 2003" came out? I can remember sitting there just hitting F5 F5 F5

What flickering issue by the way? Doesn't exist on any android device I've seen, or at least I've never seen it.

And what's this Easter egg? They fixed the wallpaper picker? :)
[Nexus 7 General] Carlovski99:
I am glad other people are reporting smoother performance. It appeared that way to me, and doubted it was just seeing what I wanted to see, as I wasn't expecting performance tweaks at all in this release. It's probably only a subtle improvement, but its the few % that makes the user experience more pleasant (Something a lot of early android tabs were missing, but Apple seem to understand)

What I was waiting for was the bluetooth fix - I have a bluetooth speaker dock and it was almost unusable due to stuttering previously. I'll check it out when I get back from work.
[Nexus 7 General] Jack Barrett:
I have no problems and framedrops with games. But systemui.apk and all android interface without games. If devs can make games run without framedrops, android should do the same with their built in interface.

Ps. Its so funny when noobs like you dont get what is micro framedrop and when I say it they feel like "oh another apple fanboi" and start to attack, kiddos.
[Nexus 7 General] embhorn:
Purely anecdotal, but battery life for my use case has improved dramatically. I primarily stream Pandora to bluetooth headphones (at work) and besides the bluetooth issues being fixed, I went two days on a single charge, which had never happened before (even on 4.1.x).

I'm happy so far.
[Nexus 7 General] knuckles1978:
Let's try and keep this a bit civilised now, but no part of my Android UI lags. I have a couple of apps that scroll less than perfect, like tapatalk HD which you mentioned, but apps, like games, are made by developers too..

Tapatalk improved a bit in its latest update BTW, its still not perfect though. Normal tapatalk scrolls smooth as silk, its just the tablet version.

If your android UI is lagging, then your device is faulty or your ROM or kernel are borked.
[Nexus 7 General] Jack Barrett:
Nope. My eyes run on 120 Hz. Yours on 40?

I see it in every android device.

Scroll something larger and see just before it stops it drops frames on 2nd or 3rd try
[Nexus 7 General] rayiskon:
Geez, guys enough with the childish chit chats. There is micro lag on all platforms, iOS included, scroll to the left (search bar) and u'll see what i mean. Android too has it's hick ups from time to time, but i think it has come a long way since the days of eclair and froyo (many of u won't even know what i'm talking about). Anyways, if iOS has stutters with it's minimalistic features (no widgets, no app drawer, tiled icons, hell, u couldn't even change the wallpaper till a while back), i'd live with android's microlag and enjoy all what it offers.

I have a friend who keeps switching between ios and android, and everytime he gets an android device he keeps complaining about the micro lags that no one but him notices (to the extent he calls it lagdroid) , and he's never satisfied. but this, mate, is not called "perfectionist" , it's a mental state, u keep looking and fetching for a single hick up, u'll never be satisfied whatever u use.

As a med student, i advise u to get out of that "state of mind" and just enjoy whatever device u have. getting frustrated about lil things like that will only get u a stroke before u even hit 40.
[Nexus 7 General] mjs2011:
I don't know, terms like microlag are just to the point where I stop reading. I used my tablet enough this morning to the point where everything that I wanted to do ran smoothly, well above my expectations. I guess that's enough for me. I'd rather enjoy my tablet than critique it to that extent.
[Nexus 7 General] knuckles1978:
Yeah, me too.

You mean besides the one from the git repo? Anyway, here's a good TLDR summary for you, with a link to the full changelog if you're so inclined.

So did the battery life improve?
[Nexus 7 General] knuckles1978:
Its a very hard thing to try and measure. Same with 'performance'. No single really noticeable improvements in either.

One thing. For the last month I was experiencing the battery staying at 100% for like an hours screen on time before it went down to 99 like a lot of people. That is now fixed on mine, battery meter must have drifted out of calibration or something, ive not actually lost an hours screen on time.
[Nexus 7 General] JakeAnthraX:
This.

I don't like how people are posting benchmarks in many threads, when the benchmarks vary a lot and they usually have other stuff installed to change it.

The implementation of Nvidia PRISM hasn't been improved with this new version sadly, I still get washout from playing videos.

I searched for this but came up empty. Is USB otg still broken on 4.2.2? That's the reason o stayed on 4.1.1 using stickmount
[Nexus 7 General] knuckles1978:
I've given up on benchmarks a long time ago, complete waste of time imo, the only benchmark I use is the way it feels to me. That's the only one that matters.

I confirm that one, they've definitely fixed that.

I'm sorry, was my "noob" badge showing? I feel like I dropped it a long time ago...

If you want to talk about lag in systemui and launcher.apk...then once again, you proved my point. You should be looking to the app developer, as I stated. Which in this case, would be the AOSP.

Remember, just throwing the word Android out there is careless. Android is a broad term describing the underlying OS. Android doesn't provide your launcher on your N7. AOSP does. Just like Android doesn't provide twlauncher on my S3, Samsung does.

[Nexus 7 General] di3cbl:
I agree with jack regarding the lag in the system ui. While for the most part it's smooth, sometimes when I pull down the notification drawer or quick settings it lags a bit, and scrolling through my apps and widgets in the app drawer also stutters to the extent that its frustrating me. I've tried my brother's iPad 1 and my friend's iPhone 5 and I must admit that they feel more fluid than my nexus 7.
[Nexus 7 General] Leonhan:
After tedious work updating to 4.2.2, I van say that is smoother than 4.2.1, but I still experience a slight lag when opening the app drawer, but I aint complaining. Really love the update so far.:good:
[Nexus 7 General] homemadehitshow:
Went back to stock 4.2.2 to try it out.

Bluetooth stuttering is gone but significant audio delay. Are others not hearing that ?

Back to the 4.1 Bugless for me :(
[Nexus 7 General] Catchpen:
Bluetooth audio is still static-y on high frequencies & no song meta-data. I'm pretty disappointed. I wonder if it will ever work right again?

People in the same boat as me in code.Google.com are leaving plenty if nastygrams to Google...like that does any good.

Stuck on 4.1.2 forever I guess.
[Nexus 7 General] issak42:
I think I noticed some audio lag via BT in a game (very little though), but I watched a whole episode of Big Bang Theory with bluetooth audio connected (MX player, 720p h.264), and there was zero audio lag and/or delay. 4.2.2 rooted stock

Connected to Logitech bluetooth/wireless audio adapter

after 4.2.2 upgrade..i find the screen color has been calibrated towards vividness ..the 4.2.1 screen was wash out..looks pale..now the photo looks more outstanding.
[Nexus 7 General] Letitride:
Yes, updated 32GB WiFi model to 4.2.2 from rooted 4.1.2 stock rom & kernel, bootloader unchanged @ 3.41 - so far so good, everything works just like before. OTA mounting is good, confirmed success with 8GB USB drive and 4G LTE USB dongle. No lags - so far ... and all of the older Apps are running without issues or compatibility errors, etc.

Gotta "love" Jelly Beans !!!!
[Nexus 7 General] littld:
Anyone else noticed you can't long-press links in the Chrome browser anymore? I like to open links in new tabs and you can't do that with 4.2.2. Pity, back on Boat until it's fixed.

Bluetooth is still broken on my N7 and GN with 4.2.2. None can connect to my jbl wireless speakers. My hox+ works without problems. Starting to get pissed.

Seems slower than 4.2.1 for me
[Nexus 7 General] ales007:
it works well on mine,but few weaks ago i had the same problem with 4.2.1 ,i solved that by erasing chrome data ,be carefull with your favorites ,you will lose them . :)
[Nexus 7 General] 2kbandit:
Stickmount needs root access. That way you will have both read/write access on the flash drive.

The is another app you can use with non rooted devices. But you will only have read access on the flash drive.

sorry guys if I am posting in wrong place

I got my nexus 7 gsm 32 GB rooted via nexus 7 toolkit

I think with custom recovery' I got the update downloaded waiting for

any issues'. root problems

please help..

Just wait for cm 4.2.2 build,and finally the 2/16 nightly was released yesterday.

Should I just update it from cm updater? Or i need the clean install??

Any advice is appreciated.
[Nexus 7 General] Logan_M:
I'm not sure but it looks like the weird color fragmentation is gone on 4.2.2. If you guys remember how menus sometimes had strange patterns behind them, I'm not noticing that now.
[Nexus 7 General] knuckles1978:
That's been confirmed, yes.. That and the notification drawer that stays open when you open it :)
[Nexus 7 General] Leonhan:
Yes it is safe to install custom recovery. You can install via goomanager,that's how I did mine.
[Nexus 7 General] littld:
Thanks for sharing that works fine again after following your advice. I'm noticing the keyboard is a bit more responsive than before with this version, less lag overall I think.
[Nexus 7 General] issak42:
Audio stuttering is still there, just less severe. May be wifi streaming from play music, or it may be BT I dunno.

About keyboard, I still keep hitting 'n' instead of space. Honestly once I typed on the iPhone and I made zero mistakes, on n7 I keep hitting n and on xperia arc s I keep hitting 'b' instead of space...
[Nexus 7 General] matus201:
I just played some MC4, the "highest graphics" tweaked version, and it was pretty smooth on stock kernel - as smooth as on overclocked kernel and 4.2.1. This of course is not scientific test, but to me the whole device seems much faster.

Overall, i'm happy. Now if they only solve the swiping issue (sometimes, when you enter the menu, your first swipe doesn't register properly)..

Weird battery stats after 4.2.2

Ref pg 10 of this thread, post by Lttlwing16 on

15th February 2013, 07:53 PM

My N7's charge showed 100% when I installed the 4.2.2 update.

The installation went off smoothly- I have a stock, unrooted tab..

When I shut down the N7, it showed a 96% charge remaining.

Now the weird thing-

After I booted up again this evening to check out the updated OS & play around with the apps etc to get a feel of the response/smoothness etc, for abt 1 hr 11 minutes;, when I checked the battery usage it showed 90% remaining, with 0 % for the screen use & abt 58% usage for Android OS.

I then shut down the N7 . When I booted up after dinner & played around for about1/2 hr & rechecked battery usage, it showed 32 minutes use since full charge, the remaining battery at 85% & again, highest stats at 49% for Android OS & 0% for screen! The previous use for 1hr 11mts had not been counted by the battery stats.

Does something needs to be reset?

What exactly did you do to bring the Android OS use down- could you plz explain what system apps did you open to reset the androis os stats, and are you also getting a 0% screen use stat?

TIA

Doesn't work without modifying default.prop in the boot image. Any modification of default.prop after boot is ignored.

4.2.2 is very good. Only time for how to root it is fun.

Ok.. Is it only me or not?

Try to put your nexus 7 in silent mode and play some media music, video. See what happens!

I use to put silent mode when i watched movies so i wouldn't be bothered by email notifications but now its ruined. It mutes even media volume when i try silent mode. And when i try to get the volume back with the rocker it will put notification volume back on. My Galaxy Nexus which run 4.2.2 doesn't have that problem. You can put silent mode on and youtube, music or movie volume will not be affected
[Nexus 7 General] rontopia:
I before E except after C sort of

,I am a first time poster.I just bought a Nexus 7 3 days ago. I quickly updated to the latest version Android I have noticed real difficulty when typing the letter O. it seems to almost always select a letter O then letter I. for instance my username is Rontoia. whenever I try to type this I end up getting the letter O and then the letter I. but I'm actually only touched the keyboard 1 time. I have no idea if this is a revision issue you or if this is an old issue or is this is just an issue with my tablet? does not happen in landscape mode.

has anyone else noticed something like this?
[Nexus 7 General] cdf3:
Volume settings have been changed in 4.2.2

Using volume widgets to silence notifications will also silence media volume. Bug perhaps?

If so, it's an annoying one.

[Nexus 7 General] skyrocket727:
I did factory reset just to make sure.. And it's still mutes media volume.
[Nexus 7 General] Keydogg1:
Did this last night, well impressed! It's even smoother again and includes the little tweaks such as the Google Now widget.
[Nexus 7 General] issak42:
Hasn't the volume always been like that? Otherwise, when you press volume rocker, press options button and just slide notification sounds to minimum. It's really not that much hassle.
[Nexus 7 General] cdf3:
They've been separate. I use a custom volume widget from HD Widgets to quickly mute notifications, yet still be able to watch videos. Now it mutes everything. I also use an app called MyProfiles to quickly switch to custom profiles I created. They are all screwed up and don't adjust the volumes separately like it did prior to the update.

Using the volume button, clicking the settings button, then adjusting the notification bar can be done; but it's way too many steps in comparison to using a simple widget.

[Nexus 7 General] alan77ss:
There were two issues for me that needed sorting out: bluetooth and auto brightness.

1. bluetooth: initially audio streaming worked well. but then i couldn't connect to my pc, despite unpairing and repairing i just couldn't get a connection. as soon as i restored back to 4.1.2 the device paired up instantly and audio was fine. the same is true with my asus transformer on 4.2.1, just cannot get a connection.

2. auto brightness still keeps changing to rapidly despite no change in background lighting. sometimes it changes every 10-20 seconds making it a very frustrating experience.

so i guess, i'm back on 4.1.2. not such a big deal, don't need the swipe keyboard, user accounts etc.
[Nexus 7 General] bunadski:
Hi all!

I updated to 4.2.2 the other night and I do 'feel' it's smoother than the last version. However, I have this annoying "Download Complete" notifications in the notification bar. These are download notifications for photos, same as when you copy pictures ftom SD cards to N7 using Nexus Media Importer app. It looks like this:

See the notification bar? Swiping it down shows this:

This happens each time I unlock N7 after a long standby time. Rebooting and uninstalling Nexus Media importer both didn't work. Help please! Thanks!
[Nexus 7 General] styckx:
Are they even your photos? Obviously some sort of app is syncing these photos from somewhere.
[Nexus 7 General] cdf3:
Mine did this as well after updating and doing a factory reset. I have my Picasa account synced to my device. I'm assuming it was downloading those photos. I haven't seen it since after all albums were downloaded.
[Nexus 7 General] styckx:
Oh yeah.. Picasa. Forgot all about that disaster.. I removed every single photo I had from there ages ago when Google felt the need to force syncing of the photos from it to your Android devices... I still have no idea to this day why they felt this was needed or a good idea.. How hard would it be to simply ask "Would you like you sync your Picasa albums to this device?" The worst was how buggy it was.. Disabling Picasa sync was supposed to remove the photos from your device. But 90% of the time it never did and you couldn't delete them via the gallery. You had to go in and clear your gallery data and reboot your device to make them disappear.
[Nexus 7 General] cdf3:
I agree. They ask should ask the user before doing it automatically. Especially since carriers have Share Data plans. Someone can activate their phone and end up using a lot of data downloading albums and not even know it.
[Nexus 7 General] James BlackHeron:
I'm still waiting for this mythical update on both my N7 and N4. I check every 12 hours and it's still not there.

I really would love to have a real mute. When I mute the device I want it MUTE. If I accidentally (or purposely) start a video and the device is on MUTE I don't want to hear any sound. That's what mute means to me. If it is 2AM, I can't sleep, I'm surfing the internets and forums, and I click on a video I don't want blaring music screaming from my device and waking up my wife. I applaud this change.

If I ever GET it.

How long does Google take to implement a tiny update like this? It's been a flippin week already. Get R DONE!

Still waiting on the update. Hasn't it been over 6 days now?

Of course, you could just download the update and install it manually, but that's not for everyone.

Never had much lag before, so I can't comment on that. However, there seems to be improvement with the screen flickering issue, while using AUTO brightness and transmitting data over WiFi. I don't find that to be as noticable anymore, since the 4.2.2 update :)
