Hello, friends !

Google Nexus 7 2012 3G 32Gb, AOSP 11.11.2017

Use Youtube app is more than 1.5 hours - the device starts to slow down very much.

And after that, i need to reboot and clear the Youtube cache and use "Trimmer app"

Is it possible to fix this, or is my tablet just very old and require anything more from it - it's pointless?

I want to mention that, my kobo arc 7 HD has a very similar spec to nexus 7!

my cpuz report: https://valid.x86.fr/a/citm4v

nexus 7's cpuz report: https://valid.x86.fr/a/xgznr6

is there a quick way to port this amazing ROM over? it makes me want to cry to see that nexus 7 gets so much more community support while kobo arc hd 7 is stuck at Jellybean.

Hardware Problem with Speaker

I got a second device and exchanged the speaker unit. Now the speaker works again (well, it's still bad by design, but it at least it's now as loud as it used to be). On the other hand the other device is now broken, obviously. :(. However, this proves that it is a hardware problem.
[Nexus 7 Android Development] 123x:
A possible workaround: You can uninstall the app and use a web browser for YouTube.
[Nexus 7 Android Development] Ahkah:
There a program called NewPipe. It's available from F-Droid and runs well on my old Nexus S (without Google apps!).
[Nexus 7 Android Development] Ler0y:
Thank you, NewPipe works great ! =)
[Nexus 7 Android Development] gmikhail:
I recommend installing the apk from here: https://github.com/TeamNewPipe/NewPipe/releases

The stores usually contain the old version.

PS: And instead of Google Play & Gaaps use https://apkpure.com/ . Available all applications from Google Play. Some apps like Google Chrome works fine even without Google Play Services.

On build 20171208 I have the same problem. On 20171018 everything is okay. All updates done with wiping system partition.
[Nexus 7 Android Development] duhr:
I have just installed this an hour ago and truly amazed by how well it works. Previously I had the AOKP Kitkat version installed on my device and did not think an newer version will run smoothly like this one does. Thank you!
[Nexus 7 Android Development] williamlaw:
I found the sound from the speaker was crashed.

It's related to hardware or rom (driver) ?

How can I fix it ?

Thanks

[Nexus 7 Android Development] AndDiSa:
Merry Christmas to you and your family! Wish you all the best.
[Nexus 7 Android Development] AndDiSa:
Completely crashed or temporarily? The temporarily crashing is happening to me from time to time, too, and I suppose it's related to audio routing bacause you can see the headphones symbol in the status bar while audio is not working. Often this happens after starting / switching to a new app but after a few seconds it returns normal for me.
[Nexus 7 Android Development] frov:
[MENTION=2188693]AndDiSa[/MENTION]: I am looking around for 8.x ROMs for my devices, including my trusty Grouper: would you say that all (amazing :good:) perf optimizations you achieved for Grouper are also adopted in Unlegacy?

I am thinking of trying a flash of that.
[Nexus 7 Android Development] adstraylight:
If you check the UA grouper thread, I don't think anyone has got the experimental 8.0 build to boot, so it's probably not worth trying yet. In terms of optimisation, I think that Andi has a lot of stuff that's not in the UA builds.
[Nexus 7 Android Development] frov:
Yep, I read that it is not yet booting. I was wondering for the optimizations, but I also have the feeling that Andi's ROM is the best for Grouper regarding that. Tnx.
[Nexus 7 Android Development] Char_G:
Merry Christmas to you, too :D

Thanks man, I can't belive this old pos of a tablet is still supported. It's incredible. I mainly use mine for streaming bedside, and for that purpose it works great with your rom.
[Nexus 7 Android Development] rand0m:
same here - was suffering a bit after picking up the nexus after I cant remember how long ... updated to this build and I am well impressed so far ... still a bit of testing to do but its looking good - besten Dank :)

only thing I see is that some apps dont seem to see all storage but apart from that I couldnt see any faults .. no SU installed ...

Bug in access permission on first start

As the Nexus 7 is my only Android 7 testing device, I need it also for development and found a nasty bug that is also in Beanstalk (based on Android 6). For convenience I just copy my message from 2016-10-14:

With other words:

App is started for the first time after (re-)installation (installation of app, not of Android OS)

App requests for read permission of audio files (external storage)

Access is granted (by callback from Android OS)

App starts background task

Background task is trying to access audio files, but access is denied for every single file

App is forcefully stopped (using the "x" in the recent apps view)

App is restarted

Access is now granted

As told, no other device I tested shows this behaviour, and even for stackoverflow this phenomenon is unknown.

Link: Google developer information

PS: Debugging is making me crazy. During debugging some files are not found, while others are found, but have length zero, and others are accessible, but not outside a debug session. Could it be a timing problem?

PS/2: It's not a timing problem, and other apps are also affected. Some music apps shows only generic album art at first start.
[Nexus 7 Android Development] lilk1d777:
do you currently have a ROM and version your able to use NETFLIX with the download feature? Thats what i'm currently looking to do as i use it for my kids in car entertainment. any info or pointing in the right direction would be great! i'm on lineage/cyanogenmod 14.1-20161130-unofficial-grouper. Haven't been able to figure a way to get netflix w/ DL feature to work. Confused w/ magisk etc
[Nexus 7 Android Development] spark001uk:
Thanks again for another great release [MENTION=2188693]AndDiSa[/MENTION] , working great. Did any battery charging anomalies ever come to light? I can still only get mine to charge at a max of 0.8 - 0.9A on your ROMs, whereas my friend's stock Grouper charges at up to 1.45A (which mine also did when it was stock). Same charger, same cable, standard factory supplied. Also tried with an Anker 2.4A. Same results, his gets about 1.4ish and mine only about 0.9A.
[Nexus 7 Android Development] AndDiSa:
Mine is charging between 0.5A and 1.2A but I am getting values above 0.9A rarely. I am using e.g. 3c battery to check the charging current. Sometimes I even need to re-connect several times until the charger is detected. Unfortunately I do not know where to check. I even have reverted the OTG-charging patch ... almost no change :(

First thanks a lot for still supporting these old devices, AndDiSa!!

I tried flashing the 20171208 build to my tilapa device yesterday, but I get stuck in a bootloop where the ANDROID logo comes up but after a minute or so the device restarts. Here is what I did, maybe someone can point me to an error or solution?

boot device to TWRP 3.2.1-0

do an advanced wipe of cache, dalvik, data and system

flash aosp_tilapia-7.1.2-ota-eng-20171208.ds.zip from usb-otg device (md5 hash is correct)

install opengapps, I tried several different packages, pico, nano maybe micro and also not installing any gapps

reboot device

Only after the very first flash it seemed to boot ok but error messages kept spawning so I could not use the device. This first try I did something different, though: I came from the last cyanogenmod based on android 4.4 and TWRP 3.0.something, wiped only data, cache and dalvik, flashed AndDiSa's ROM without wiping system, failed to install both micro and nano packages of opengapps (due to low space), successfully installed pico package, rebooted
[Nexus 7 Android Development] Ahkah:
No, this is not off-topic. The described symptoms look very similar. Good to know that this bug is still present and will never be removed. I hate this OS! Some comments for bug reports I provided are totally ridiculous. For example:

- Bug: Can get composer from mp3 files, but not from m4a files

- Answer from Google: Bug closed, reason: works as expected.

- Bug: Developer documentation incomplete, constant blabla is nowhere explained

- Answer from Google: Bug closed, reason: works as expected.

... and so on ...

:(
[Nexus 7 Android Development] spark001uk:
OK I've just tried my new Anker again with a short Nokia data cable, it's a good quality thick one which is screened as well (the connection of the screen seems to make a difference on a lot of devices I've tested over the years, I think the lower voltage drop helps convince the device it's connected to a well made cable). After a few mins it seems to have settled down at 1.05 - 1.15A, think that's about the best I'm gonna get. I'm allowing for a slight voltage drop through the sense resistor in my USB meter as well, so in reality it may be a touch higher without it.

If anyone's wondering, the Anker charger I got is this one. It can supply a good solid 2.4A from each port, not shared as a lot of cheap chargers are.
[Nexus 7 Android Development] slybunda:
whats causing the charging issues? this rom or something else?
[Nexus 7 Android Development] AndDiSa:
Probably it's only our aging batteries, probably it's a problem with wakelock/interrupts, I don't know. I (and many others) had already charging issues years ago, so probably it's also related to the devices hardware...
[Nexus 7 Android Development] abhifx:
as per forum posts and tons of youtube videos, charging issue seems to be more related to charging hardware rather than software issue. this can be easily tested by charging through pogo pins which should charge better and faster.
[Nexus 7 Android Development] n3kf:
If you have a bit of electronic experience, I tied a Qi receiver into the battery leads in my device. Now I can wireless charge it at about 1.6 amps. Downside is device does not know it's charging. Upside is it charges very fast and no more worries about software and hardware issues charging wise.
[Nexus 7 Android Development] Buratei:
Been using it for some time as a car tablet, mainly (well almost strictly) for music playback thru an external USB DAC. Not sure which version I have right now but OTG charging still works so probably not the newest release.

Quite impressed and happy with battery life and smoothness, but I have one lingering annoyance. I have installed powereventmanager.apk from the autodroid (kk-based) thread, and found it works on and off. Specifically, auto suspend on power loss doesn't seem to trigger more often than not. To enter deep sleep, I need to pulldown the PEM notification panel and hit the suspend button manually. Tried replacing PEM with autosleeper, only to come back to PEM due to severe battery drain.

Is there something else I could use for auto-suspend?

Another thing, I don't seem to be able to locate "cpu hotplug" in kernel adiutor with this rom; I need that to turn off mpdecision which produces random crackling in certain songs.
[Nexus 7 Android Development] aghy91r:
You could've used the connectors on the side of the tablet to connect the Qi receiver to avoid overcharging situations. Because it it a Li-Polymer battery and it may explode with overcharging.
[Nexus 7 Android Development] quique2:
Sorry for the delay in reply. I had it working with this ROM, build 20170707 grouper (from earlier in this thread), and Netflix version 5.5.1 build 21226. I can't remember if I just downloaded the Netflix apk or if I got it from the store. I also haven't used it in the last 2 months so I don't know if Netflix has locked out older app versions but it was working just fine. I'm currently having some wifi issues so I can't test it unfortunately.
[Nexus 7 Android Development] n3kf:
Tried that first. But the software/hardware still limits the charging. Batteries that are used in these devices have a battery protection circuit built into the pack to protect from over charging.
[Nexus 7 Android Development] aghy91r:
Boot-loop while charging

I've flashed this ROM 3 times and every time the process went smooth, also with the Gapp mini. But I noticed that the tablet goes into bootloop several times (when it's connected to a charger) when I restart the device, then it boots into recovery mode, after disconnecting the charger and reboot the device it works perfectly. I've wiped the cache and dalvik/cache several times with no luck to fix that. Re-flashed the ROM again, same problem.

Nexus 7 2012 Grouper 32GB

Android 7.1.2 (Build 20171208)

This happened before and after flashing the SR1-SuperSU-v2.82 (systemless)
[Nexus 7 Android Development] AndDiSa:
This behavior might be related to the fact, that you even cannot use the power / volume buttons when you are in bootloader mode while having a charger connected.
[Nexus 7 Android Development] aghy91r:
while having a charger connected, I can use power/volume buttons in the bootloader after several attempts of clicking though

It's been a while since I been on here. Which version has the normal charging while on. Last I hear was that some of the latest had issue with charging while on that it would only be I believe half speed.
[Nexus 7 Android Development] Ahkah:
OT

As far as I understand "world" is a singular noun, and "fall" is a plural verb, so I see a mismatch here. Is this poetry or medieval English or dialect? :)
[Nexus 7 Android Development] pjcanales:
I'm guessing you don't watch the "walking dead" which it's reference to. Yet you do realize that not everything has to make sense since knowledge as we know could be different in another dimension. Beside why bother responding to a post completely off subject.
[Nexus 7 Android Development] slybunda:
anyone else get massive battery drain overnight? tablet is dead in the morning?
[Nexus 7 Android Development] AndDiSa:
my overnight drain is about 3-4%. Do you have a process running wild? ... or probably it's an indication that the battery is going to die.

Version with January security fixes (2018/01/05) uploaded

Today I've uploaded a new version of the ROM (Grouper / Tilapia) containing the January security fixes. You can download them from the OP. I've cherry-picked the related commits as Google didn't update the 7.1.2 branch (yet). As I already wrote, no fixes for Sprectre for now ... just wait and see whether we will get them. (Really speaking I do not expect them :()

Beside that a slight change in the kernel: I disabled LP overclocking as I noticed that battery consumption in relation to performance is better without LP overclocking. Due to that I had to adjust the intelliactive settings a bit, too.

If you are familiar with the updating process, you can download the new versions also from here: Grouper-OTA (20180112) / Tilapia-OTA (20180112)

And as always: flash on your own risk ...
[Nexus 7 Android Development] AndDiSa:
[MENTION=4336485]rottenwheel[/MENTION] I suggest to do it in the following way:

- go to recovery

- flash the new ota

- reboot to recovery (normally not needed, only to be sure ...)

- flash Magisk / SuperUser

- reboot to recovery (normally not needed, only to be sure ...)

- flash microG

- clean cache / dalvik (to be sure, as it it only a minor update cleaning dalvik probably not needed)

- reboot

[Nexus 7 Android Development] DumF0rGaming:
You may already know, but I'm gonna tell how brilliant dude [MENTION=2188693]AndDiSa[/MENTION] is . For the first time I can tell that Nougat ROM isn't made by Tilapia hater :laugh:

Compared to November build:

RIL is working, haven't tested the data yet, shows H+

Sound doesn't stutter while heavy typing

Compared to 3.4 ROM from Jan 4th:

It's buttery smooth! I didn't expect it to run as it is on KitKat. I don't want to install LSpeed anymore, even with snowflakes on Lawnchair! Presicious work on governor tweaking can be seen.

It's usable! Not only it boots as quickly as it should, but it doesn't freeze in half of the way. Futhermore, it didn't freeze completely for 50 minutes I've spent setting it up! All the time it was reasonably warm, not burning hot. And I think it will stay cold till you start watching videos - Youtube 12.49.55 doesn't crash for me, 720p60 is running smoothly.

Speaking of 50 minutes SoT, it took roughly 25%, should consume even less, since I had NFC and geolocation enabled, had been using recovery multiple times, have installed many apps. As for charging it's definitely a hardware problem, mine takes from 0.23 to 0.63A on any ROM.

So far there's only one thing broken - MTP doesn't work at all and it breaks adb untill reboot, other modes are working fine. MatLog shows successfull switch and start of the server, not a single warning

God bless you [MENTION=2188693]AndDiSa[/MENTION], Tilapia can be daily-driver again. I hope many devs will take a look at your sources and you personally will try to do something with Oreo. :highfive:

Those who will install this ROM should flash ROM and gapps together, then apply a command by this guy to avoid issues:

I've found that Setup Wizard doesn't crash if you flash Beans GApps (Mini). The crashes have only occurred for me when using OpenGApps.

Same thing on my Galaxy S5 and Nexus 6P.

I do agree that the 01/12 build is great! Lot better than the 3.4 builds, those were very laggy for some reason.

MTP Host also crashes a lot on my Nexus 7.
