UPDATE

Well of course I would have crappy luck. I installed the JSS15Q update and it got stuck at the Nexus X logo after it rebooted. I had to go into Recovery and factory reset which wasn't a big deal since I was planning on unlocking the bootloader right after the update. But the fact that I had to wipe from Recovery was pretty sad and leaves a feeling of uncertainty in me about this tablet.

UPDATE #2

After testing with YAMTT some more, it seems that my touches are slightly messed up. When I bring my fingers towards each other on the screen, the touches start to flutter a bit and when I let go they are all still present on the screen and slowly move outward then just unregister.

It doesn't seem to affect my normal usage thus far, but time will tell if that changes.
[Nexus 7 (2013) General] sfhub:
Added this warning to first post:

*WARNING* JSS15Q touchscreen firmware is a one-way street, no going back

In your screenshot you still have 98% battery after 44 minutes. Of that Google services has used 43% or roughly 1% total. 44 minutes in may be a little to early to panic?

I got the pop today for a system update, but based on what I'm reading here I'll hold off. Maybe I'll just wait till the next major update comes down the line since my device it's running flawlessly right now on JSS15J

I'm having zero problems with the update, just played almost two hours of Asphalt 8! Which BTW Is awesome
[Nexus 7 (2013) General] zoitee:
OK, I got mine from Ebay because it is not sell here. (Thailand)

It is 16 Gb Wifi 15J with ghost touch when I move more than two fingers to the same point(zoom in), unregister touch sometime(YAMTT), no reboot problem and I not use GPS.

After flash to 15Q ghost touch is still there, unregister touch AND sticky touch that I never met before.

No reboot, no comment about GPS.

It is still a beatiful and usable tablet but not for typing or playing game that need fine control.
[Nexus 7 (2013) General] time2303:
I had an issue with both stock 4.3, CM 10.2 nightlies and the latest PA where playing a video would freeze and crash, JSS15Q fixed it.
[Nexus 7 (2013) General] Igorsep:
I was having random reboots on JWR66N and now I'm on JSS15Q and I'm pretty sure battery is not normal eventhough the reboots seem to have gone (thankgod)...

It's down to 90% (from 100%) after 3h of standby, no screen on whatsoever. 1% down every 20min. "Android OS" is taking 80% of the battery drain. This is my first tablet but I think it's too much of a drain for one...
[Nexus 7 (2013) General] Shadowguy:
I have no multi touch issues at all using yammt maybe a slight ghost touch when using 3 fingers but it quickly goes away.

This is before the latest OTA which i am now scared to even flash.
[Nexus 7 (2013) General] MattDN93:
Yeah definitely I'm having pretty bad battery drain as well...it's losing charge so quickly compared to the 15J build...its a toss up, better battery or working touch apparently...
[Nexus 7 (2013) General] and2nckiko:
im on build jwr66n out of the box been using the tablet for a week now without any issue spreading in diff forums...i also have a decent battery life...

i receive an update today but havent installed it yet..my question is do i need to?

i have also read some users having issues when installing..

as of now im loving my first tablet my my friend purchased this from game stop and send it here in the philippines
[Nexus 7 (2013) General] player911:
I've tested multiple roms and it never really gets better. I don't have lots of issues with tapping or 2 fingers or using 2 hands, but if you lay the device down, all goes to ****.

Here is a good test that is easily duplicated. Using YAMMT app, use the Paint tool. Lay the tablet down and only touch the screen with 1 finger. Do a long, hard, solid, slow, slide starting from the top half and drag down to the bottom half.

The top part doesn't pick up my input until I get about half way down. It picks up my taps and a fingernail but not my finger.

I've tested it on 15J, 15Q, Build 3 CM Kanged, and Build 9 CM Kanged.

The multitouch feels better and is picking up my tapping better on later builds, but the swipe test fails every time. I took a video but don't know how I can upload it. Maybe youtube later.
[Nexus 7 (2013) General] jrwingate6:
Thought I should share my experience upgrading to JSS15Q. I was on JWR66N with no issues or what I thought was no issues. I actually did have some slight touch issues but nothing crazy like not registering touches when laying on a table. I just had some issues with long press and it turns out my keyboard touches were little off or sluggish.

The update not only improved the touch issues but it also improved an already good battery life. I also see an improvement in the overall speed of the tablet which was already fast before.

I was scared to try the update but I just couldn't resist anymore. I am still under the Best Buy return period so I figured that now was a good time to try the update and I'm glad I did.
[Nexus 7 (2013) General] sfhub:
It doesn't matter which ROM you use. The multi-touch firmware is loaded into the hardware and won't get downgraded.
[Nexus 7 (2013) General] sfhub:
You don't need to if everything is otherwise functioning.

The corrupt eMMC only seems to affect a few, the PRNG only affects folks using encryption but the individual apps will eventually get patched.

GPS you can get individually without upgrading in this thread:

http://xdaforums.com/showthread.php?t=2421373

I guess some apps like netflix require the newer build so that might be a reason for some to upgrade.
[Nexus 7 (2013) General] SubMatrix:
I wonder if we can get a dev to comment on whether it is possible to adjust digitizer voltage via kernel or something else. If so, it seems the best option would for someone to dev a setting where each user can adjust the voltage settings until their touch problems are fixed (since everyone seems to have varying degrees of sensitivity issues, some oversensitive and some undersensitive).

If it is true that every digitizer is different due to different manufacturers or whatnot, then it would seem to be difficult for Google to put out a fix that would work universally for everyone. This manifested itself in the 15Q update which fixed touch issues for some, didnt do anything for others, and actually made touch worse for still others. Individual touch voltage control is something Google would never release to the public, but if my (and others like sfhub) hunch is correct then this would at least allow those of us who are unlocked to take control of this issue once and for all.
[Nexus 7 (2013) General] BTT8:
So I can download the factory image 15Q, flash it via TWRP, have all my data/settings erased, and I'll be good to go?

No need for adb sideloading or reflashing stock recovery?

I'll take it. :good:
[Nexus 7 (2013) General] sfhub:
With the factory image, you can choose to keep or wipe your data.

You don't flash it via TWRP. It is done through fastboot.
[Nexus 7 (2013) General] sfhub:
I looked through the driver code a few days ago and it doesn't seem obvious where you would actually set voltage. The only communication between the driver and firmware regarding power is what the power source is:

0x52 0x40 0x00 0x01 => Battery Mode

0x52 0x41 0x00 0x01 => USB and AC Adapter Mode

0x52 0x43 0x00 0x01 => SLIM Port to HDMI
​

There is also some communication about XY resolution, finger size, and finger pressure, but that seems like generic info rather something granular enough to control what we are interested in.

Also all the "fixes" asus has been adding to address our issues appear to be taking place in the multitouch firmware so I assume that is where the changes need to happen to affect the behaviors in the granularity we are interested in.

That multi-touch firmware is just provided in binary form. Someone would need to decode it to figure out where/how to make changes.
[Nexus 7 (2013) General] sfhub:
I thought this post was pretty funny:

Perhaps as a non-violent Ghandi-style protest folks should flood Google with bug reports and posts using the touchscreen as-is to type, without bothering to correct and they should include a signature saying "This message was typed on my multitouch-challenged nexus 7 2013"
[Nexus 7 (2013) General] and2nckiko:
i agree its kinda funny :)

and you have a good point..
[Nexus 7 (2013) General] player911:
Well I don't know how true that is but mine seemed to get worse AFTER the update to 15Q. I can't pinch zoom in maps, my keyboard keeps doing alter characters from like a "tap and hold". And my widgets keep trying to move around instead of scroll.

I can also replicate weird touch behaviours after 15Q that weren't a problem in 15J.

Sucks but I hope this isn't the last of the "fixes".
[Nexus 7 (2013) General] sfhub:
I am not sure if you parsed what I said correctly. I didn't say 15Q wouldn't make your multi-touch worse.

What I said is once you get the multi-touch firmware from 15Q, downgrading your ROM/kernel back to 15J or 66N won't get you your old multi-touch firmware back so if it got worse in 15Q, you are "stuck" with the "worseness" until another update comes out (or if it got better, you can go back to 66N or 15Q and keep the "betterness")

If you post your dmesg logs I can prove to you that your firmware is stuck at 15Q levels once you upgrade to 15Q, even if you downgrade to an older ROM/kernel.

You are not alone.

I was happy before the update but now I'm having these weird ghost touches and happens really often when I scroll. Now I'm starting to dislike my Nexus 7.

[Nexus 7 (2013) General] rafa3L:
I was LOL when I read that reply in the Google forum. It does help get the point across, but I'm sure the Google and Asus devs are well aware of the problems. I hope they are considering hardware modifications if software is going to do the trick.

I've turned on "show touches" to help me understand what this unpredictable tablet screen is doing at all times. It helps me know when to pause due to a stuck tap which I'm seeing way too often.
[Nexus 7 (2013) General] sfhub:
I've had show touches and show pointer location on for weeks :)

I don't even know what the status bar looks like anymore.

When it is late at night and I am tired, I start thinking the pointer trail(s) are stuck or dead pixels. Amazing I can still see one pixel on/off on this high-density screen.

They are obviously aware of the problem, but may just think that their recent update fixed the problem for most people and the remainder are small enough to be handled as RMAs. Instead of folks threatening class-action law suits like Mr. Esquire, I thought a good alternative is just to embarass Google/Asus into doing the right thing by letting them see up close and personal how frustrating it is for people with the problem. I don't know what is more frustrating, typing those posts and correcting them, or reading those posts uncorrected.
[Nexus 7 (2013) General] danvee:
I'm thinking that neither would have much effect.

They're floundering right now and probably wish above everything else that this would all just go away.

Newsflash.... It's not going away.

2 friends just (in spite of my warnings) purchased a pair from Walmart.

Only took 2 hours for the rebooting and freezing to start, and they hadn't instructed that apps be restored. All was dead stock + 2 updates.

I told them to call Google CS and follow all instructions.

CS had them do 2 factory resets, boot into safe mode and another reset. Still acted up.

Only other info I could get was that they were July production.

They were too embarrassed to bring them to me to grab more data.

Walmart has them back now.

They said that the salesperson walked to the back and placed the 2 tablets on top of about a dozen others, tagged as return/defective.

At least they got a refund. I'm past that window of opportunity and wait along with the others for a real solution from Google /ASUS.
[Nexus 7 (2013) General] Igorsep:
Anybody got a solution for the excessive battery drain on JSS15Q?
[Nexus 7 (2013) General] sfhub:
I don't see the excessive battery drain in JSS15Q, but one option you can consider is reverting to the previous version and then just applying the GPS fix in this post:

http://xdaforums.com/showthread.php?t=2421373

Your touchscreen firmware is stuck at JSS15Q A042 levels regardless so there should be no difference with your touchscreen from your current levels.
[Nexus 7 (2013) General] SubMatrix:
sfhub, if flashing JSS15Q updates touchscreen firmware to JSS15Q levels, how come "downgrade flashing" to JSS15J doesn't downgrade the touchscreen firmware to JSS15J levels?

It's a great comfort that all of the resources that Google and ASUS have to bring to the table are 'looking into it'.

Makes me feel like the money invested in these (no longer returnable) $270 paperweights was very well spent.

Didn't get my hands on one yet, so I can't say what version it's shipped with.
[Nexus 7 (2013) General] cocchiararo:
After some more testing with the developer option to show touch (not trace), i noticed that sometimes my touch remains "stuck" after i lift my finger.

This is on JSS15Q, was not present before while i was in JWR66N.

I have not detected the touch detection issues.
[Nexus 7 (2013) General] danvee:
Yep.

Google would recommend a factory reset to cure that.
[Nexus 7 (2013) General] bandit_knight:
It's the same here. My multitouch was perfectly fine before the last update. Since it came I noticed this issue twice. I tapped on an icon to open an app and instead the icon remained pressed as if I was trying to move the icon to another place on the screen (via a tap and hold).

salaam,

before and after last update (jss15q) I still have had issue with my bluetooth. my nexus can not transfer data both receiving and sending.

Please give me your kindest advice.
[Nexus 7 (2013) General] cocchiararo:
it happens for me quiet often with on screen buttons after longpressing an app in the app list (after presing the multitask button), and trying one of their options.

It also happens while typing, but since i keep typing, a letter ends up being a symbol, a letter gets missed, and the next letter appears (this happens because the tablet thinks i long pressed on a letter, then pressing the next one "releases" the first long press, and the next one is registered)

This happens with swiftkey that has more long press options, the stock keyboard has the issue (because it is not the keyboard, it is the touchscreen :P), but it is not that relevant.

It is really easy to spot on stuck touches on a buttong that turns "blue" or an app icon tho

Hi all,

Be wary of doing this update. I was having no issues until I received this update and installed. Now my Nexus 7 (2013) randomly reboots roughly one to two minutes. Happens in multiple apps.

You're the kind of person that will crap on any manufacturer for anything, if you get sick of Google go to another tablet OEM then and say how you're "up to here" with their issues when something doesn't work quite as expected. Others are trying to help by informing whether the update helps or not.

On another not in case it might help, I had touch issues on JSS15J with YAMTT spazzing when the device isn't plugged in or on a desk. JSS15Q fixed the issues, flat on a table, in hand and plugged in are fine. June 2013 production date.

Also having an issue with my Bluetooth ear piece. Unless I use the app that pushes audio to my ear piece. Think its called mono bluetooth.

The only thing i have yet to do is setup the multiple profiles I had. Again this was with the JSS15Q build. The other odd thing i noticed after the ota update was when i uninstalled an app the nexus7 would reboot. That is also working better now. Anyone notice if you clear app caches is leaves 12kb?
