That may be a strong indication that your battery is getting older and is no longer able to always keep the charge / has no longer its full capacity ... for me it started in a similar way.
[Nexus 7 Android Development] tbmmbt:
Thank you. You could be right as it's obviously an old device but it's never really had much use and actually when I powered it on a couple of days ago before installing your ROM it was surprisingly still on about 80% from being charged maybe a couple of months ago. It also seemed to charge OK on the previous ROM. Maybe I'll try reflashing and wiping cache/Dalvik for good measure.

Anyway, even if it does charge slowly it's much more usable than it ever was and still making my daughter very happy!
[Nexus 7 Android Development] xoses1973:
AndDisa can change file system from ext4 to F2FS in this ROM?

Gracias

I converted over to F2FS before flashing the ROM and it works great

I've been using this rom for a few weeks, and it started off well but unfortunately its no good - it's started to constantly freeze entirely and has to be hard reset. Tried a fresh install but started freezing again after about a day. It's become unusable so I've gone back to stock.
[Nexus 7 Android Development] jjsan:
do you have some app or activity during which this happens?

im using it everyday without any problem. its amazing rom
[Nexus 7 Android Development] mdncb:
It crashed consistently after using NewPipe (YouTube replacement) after a few minutes, but then it also started freezing while using other apps. But before that I'd used NewPipe for weeks with no issues.

After about half an hour of stock I couldn't handle the Google invasiveness so I'm trying this ROM once more (posting this message from my nexus 7 with this ROM right now). I suspect Accubattery might have been causing problems since I usually always install that first, but haven't this time and so far so good, but we'll see. Hoping for the best. I love this tablet.
[Nexus 7 Android Development] :
Ime, there a few (very few) apps that can grind this ROM/device to a halt. I've no idea why specifically. Maybe they use more system resource? I had one yesterday, the NY Times app. Installed it and my grouper became a slug. Uninstalled it and all was fine again.
[Nexus 7 Android Development] _tike_:
Unfortunately I had to reset my Nexus7.

I used the pixel launcher 8.1.0-4429924 and was really good.

Is there a newer version that runs on the N7?

And as always, thanks to [MENTION=2188693]AndDiSa[/MENTION] for his great work, the device is still running 1a, slowly but really well.

Sorry for my bad english :)
[Nexus 7 Android Development] MacLeod100:
Hi In the latest version of the rom i notice regular freezing of the tablet on charge or on battery

Only rebooting it make responsive again

Anyone else have same problem ?

PS

I did a clean install

Charging - discharge ratio is unbalanced

Is discharging faster than previous version
[Nexus 7 Android Development] AndDiSa:
The only difference between this and the previous version are the security patches for March 2020. I doubt that this has much influence on the responsiveness ... much more likely are updated versions of the Google Play services.
[Nexus 7 Android Development] MacLeod100:
Thanks for the quick response Andisa

In undestand that and seems i have to live with it
[Nexus 7 Android Development] mdncb:
It's been another few weeks and the freezing issue came back. I can't work it out, it's completely inconsistent. In fact, I almost couldn't go back to stock as it would even freeze every few seconds at the bootloader. No idea what happened. I'll try stock for a few weeks and see if it replicates, maybe it's a fault with the device itself.
[Nexus 7 Android Development] mrn123:
I am also facing the same issue.
[Nexus 7 Android Development] Sam Nakamura:
There shouldn't be any custom software interfering on low level bootloader stage so the only logical explanation is some parts of the hardware failing on you causing freezing/stuttering... would be really surprised if there's any other explanation of this issue
[Nexus 7 Android Development] AndDiSa:
for sure some of you were alread awaiting the new releases. I've just updated the repositories, too.

Here the links of the builds for those of you who would like to test them:

Grouper OTA-Package (Build 20200408) (md5: f58efac2ae472de8fed762945e7c158f)

Tilapia OTA-Package (Build 20200408) (md5: 6a12cd418862130684af61c0c428d5b9)

... and as always, the builds are not tested yet, so please report issues / findings. If there are no issues I'll update the OP within the next days.

Stay healthy!

You're right. After more testing it's clear that the flash memory has completely worn out. It's a real pity, I was enjoying this ROM a lot and all the problems were with my tablet. Still, I got a lot of use out of it over the last eight years but that's the end of it now.
[Nexus 7 Android Development] breaktheblock:
Noob question if I change ROM will it uninstall root created my Magisk completely? Do I have to uninstall Magisk and it's folders in order to remove?

I have googled this but can't seem to find the answer in plain English.
[Nexus 7 Android Development] TureX:
If you change ROM I suggest you to do a clean install(wipe data ,cache\dalvik and system), so yes that will delete magisk
[Nexus 7 Android Development] breaktheblock:
Thanks for confirming.
[Nexus 7 Android Development] nipon101:
battery drain so fast, and the screen auto wakeup dozens of times per day.

Wiped all 5 partitions and then did the clean flash
[Nexus 7 Android Development] Ed Castiello:
Greetings and thank you very much for this amazing rom. I installed it yesterday without gapps because I think that software was the responsible for freeze my tablet with the last installed rom Cyanogenmod 12.1.

Instead I installed the FDroid.apk using adb and then Ghost Commander as file manager and Termux also. I use Opera web browser that can be downloaded from its own web page and when I need another app not included in F-Droid repos I use Apkpure or another alternative from their web pages (I don't like to install the apps).

I'm still testing and the rom seems to work very well but I have a question. Using "htop" in Termux I see that it has a swap partition of 256 MB that in fact is a "zram" partition. Doing a "cat /proc/sys/vm/swappiness" it gives me 100 which means it starts swapping very soon. In Linux machines with a hard disk swap partition the default value uses to be 60 (I use 30 on my computers) so the question is if it is recommendable a lower value for the Android "zram" swap partition also.

I can change it with "echo" command on swappiness file but this is just for the current session. What file is used in Android to make this changes permanently?

Thanks again for your work.
[Nexus 7 Android Development] AndDiSa:
zram means swapping into compressed ram disk so it's fine that memory which isn't used to be "swapped" into compressed memory. As decompressing zram is quite fast I would not change the settings. Nevertheless if you would like to, easiest way would be to use e.g. KernelAdiutor or something similar.
[Nexus 7 Android Development] Ed Castiello:
Ok, I'll keep the default settings then. Thanks. :)

The best Grouper Rom

Thank you for this amazing rom

It gives my device full functionality and extra

its just great to be a user.
[Nexus 7 Android Development] enderzip:
does this rom support f2fs?
[Nexus 7 Android Development] johndaog:
Yes it does support f2fs

Hello [MENTION=2188693]AndDiSa[/MENTION] , i am a fellow user of your Roms. Due to a brick situation i was out for some time. Now that my loved Nexus 7 is back on it's feet, i flashed your latest Rom. But i am having a minor really minor issue with your rom. After i intall gapps i am not able to access de settings menu through the setting icon (idk if you understand me), i mean i want to go to setting i have to pull the notification bar, keep long-press on any icon and then with a gentle swipe to the right to display the side menu, i am able to enter any setting i want. The curious thing is that before flashing OpenGApps that did not happen.

[Nexus 7 Android Development] iMadhaV:
Yes, I also observed this. I have flashed my Nexus few days back only.
[Nexus 7 Android Development] garryweil:
I'm on the 20200408 build and I have no problems. I would try reinstalling the build.
[Nexus 7 Android Development] AndDiSa:
[MENTION=4539880]The_Pacifier[/MENTION] [MENTION=4710466]iMadhaV[/MENTION] What Gapps did you flash? You need to flash pico-Gapps, all other versions are too big to fit into the space left on the system partition.
[Nexus 7 Android Development] Diego_992:
Flashed pico-gapps with no txt file that will kill or delete any vital apk. Setting are working just a little weird to get to. I have flashed so many Roms i've lost track. It is just a minot issue that never happened in other previous versions of your Rom
[Nexus 7 Android Development] iMadhaV:
Yes, Pico only.
[Nexus 7 Android Development] garryweil:
Me too, Gapps-pico
[Nexus 7 Android Development] zivel:
excellent work

thank you [MENTION=2188693]AndDiSa[/MENTION]

using the provided instructions i flashed this rom without any issues, everything runs just fine and i'm really surprised how much life there still is in the old grouper that i had stored away unused for a few years.
[Nexus 7 Android Development] fsw_informatrix:
Same build here and also no problems at all! Indeed, I would wipe everything (not TWRP, of course) and start over with a clean flash...
[Nexus 7 Android Development] sadsack5000:
No AOSP apps?

Hmmmm tried flashing a few times over with this version and the last but for some reason i dont get any AOSP apps at all!

No browser, camera .....

The only app i keep getting is "Email" and that refuses to work with my gmail address

Where am i going wrong?
[Nexus 7 Android Development] skugpezz:
Flashed this rom and no camera app. Not a big problem for me though.
[Nexus 7 Android Development] sadsack5000:
Uh ok. Is this rom supposed to come with AOSP apps? i thought that was the point

Dont really want to be downloading replacement apps from the playstore e.g. gmail, chrome, calendar etc
[Nexus 7 Android Development] mikeataol:
Android Open Source Project builds are usually just a barebones shell. they are smaller than a preloaded device's build, and you control what goes on it.

I have never seen an AOSP build that compared to a device preloaded from a manufacturer.

You get "settings", "camera", maybe a browser (but not always), basic functions only hopefully making all the devices of your tablet work (WiFi, Bluetooth, camera, phone services if equipped etc.)

Yes, you can get away with no Gapps, but to run a lot of brand name apps, you need to load a Gapps package.

if you have a device that only runs certain apps that do not require Google functionality, then fine... (and I've done it, using a device just for say sports or IPTV ), but if you want things like location, maps,weather, or whatever, you almost always need the Google functionality that a basic Gapps package provides.
[Nexus 7 Android Development] sadsack5000:
Right, now i understand. Thankyou for clarifying. I am hoping to use my N7 as a lite browser/emailer so thought that i was missing the respective AOSP apps.

Do you have any recommendations for apps to fullfil said lite browser/emailer?

Regards
[Nexus 7 Android Development] mikeataol:
I dont use any tablet for email... cant recommend anything there.

There's lots of places to get apps, I would think Firefox installs without any Google add-ons needed, but I'm not positive.

There's an area of XDA-developers just for apps, many are geared to devices without any Google stuff...

[Nexus 7 Android Development] Swanee123:
I use AquaMail with AndDiSa ROM. Works very well. I use Firefox as well. Slow but stable
[Nexus 7 Android Development] HTCDreamOn:
I've found DuckDuckGo much faster than Firefox, as suggested above. Some sites don't work though, due to the default script, cookie, tracking blocking etc. which can't be disabled. It's snappy enough for quickly searching something though, which is all I use it for.

In general I've found the best way to use the N7 now is with this ROM without Gapps, and just a few apps from Fdroid. You'll probably find you don't need a full Gapps installation anyway.
[Nexus 7 Android Development] sadsack5000:
This is all good feedback, thankyou everyone. Nice to see there are still a group of people still interested in keeping old gear alive and useful.

My first objective was to remove all bloatware from the N7 which i've achieved and now need to research low-profile apps to put back on the device

Stay safe
[Nexus 7 Android Development] fsw_informatrix:
Dolphin browser is not bad at all on my grouper and I'm following here on XDA the dev thread of Kiwi browser, but I still haven't test it yet (Dolphin suits my need for now).

Hope this help.

Stay all safe!
[Nexus 7 Android Development] kozmo2k4:
For browser, use Firefox or Brave.

For email, FairMail is open source.

All are on F-Droid.

Grouper SystemUI.apk

Hi,

By trying to enable screenshots with flashable J0sh1X's MOD+partial+Screenshots+cm14.1.zip I softbricked my GROUPER tablet : SystemUI.apk crash at early boot stage.

Please someone could share his SystemUI.apk as this week I don't have easy access to a setup with needed tools to extract from release ROM ?

You can get it this way in case you have runtime patches or no root browser :

Twrp : mount -> system, advanced -> file manager : /system/priv-app/SystemUI/SystemUI.apk, copy to /sdcard/...

I was using GROUPER 20200304 but I think any version between 20190610 and last will do the trick as changelog only report security patches since then

Big thanks in advance :)
[Nexus 7 Android Development] breaktheblock:
I have decided to install fdroid onto a fresh install of the latest build, when I connect my usb-otg the system says it needs formatting so I'm trying to install the all with twrp but am struggling to copy the apk to the system files, any ideas how I can do it?
[Nexus 7 Android Development] adrenochrome25:
What do you mean by struggling ? system is mounted ? write protection checkmark disabled ?

There's a third method you can try : adb push ( method details : 'adb push apk system' -> first link to stack overflow)
[Nexus 7 Android Development] breaktheblock:
Apologies I'm a noob, I need all the options explained to me. If I could do it with just twrp or the ROM that would be great. I have googled but I cannot seem to find the answer, can someone talk me through how to do it.
[Nexus 7 Android Development] adrenochrome25:
Why do you want to install it as system app ? Maybe it offer extra features but it can perfectly work as normal app : just download the APK file and install it.

If you really want it as system app, go to twrp 'mount' button and enable the 'system' partition, verify that 'mount as read-only' check mark is unchecked, now go back to twrp main menu : extra / file manager and put the APK file in /system/app/

.done!.

While you are at it, if you could copy your system/priv-app/SystemUI/SystemUI.apk to your /sdcard/Download and put it on some cloud or some file sharing platform it would be great because I really need this file :)
[Nexus 7 Android Development] mikeataol:
Here's the one from the build that displays as 20200303
[Nexus 7 Android Development] breaktheblock:
I appreciate your help but how do I 'just download and install it' as there isn't a browser in the ROM.

I have managed to copy the APK to the /system/app and also /sdcard/download directories but these don't seem to have worked after booting into the ROM.
[Nexus 7 Android Development] mikeataol:
you can try using the built in pseudo file manager

Go to "Settings", "Storage" , "Other" choose "explore"

maneuver to the directory with the browser apk ...

double tap it and it should launch the package installer.
[Nexus 7 Android Development] breaktheblock:
I have now found this but it gives a message 'There was a problem parsing the package'. :(
[Nexus 7 Android Development] mikeataol:
Then you need a different apk.

for example:

You may have tried installing 64bit arm v8 package when I'm pretty sure you need arm v7 apk's for this Nexus.
[Nexus 7 Android Development] breaktheblock:
This sounds plausible. I downloaded from the only link on the front page of the fdroid website. I have searched the site but cannot find any alternative version, do you have a link?
[Nexus 7 Android Development] adrenochrome25:
i just tested fdroid default apk on grouper and it's arm7 as it install&run perfectly. i guess you downloaded it on computer and some antivirus broke the apk by thinking it's a regular zip and tried to mess inside (every time i download an apk on office computers it do that).

Please redownload fdroid directly with the tablet browser :)

and for file managing/browsing, you can download MiXplorer on xda, this file manager really fulfill all needs and beyond

---------- Post added at 08:12 AM ---------- Previous post was at 08:03 AM ----------

thank you very much! now the tablet is booting again :) but navigation buttons/key and top notification bar did vanish ... really dont know why ... maybe while it tried to boot with the broken SystemUI, android tried to tweak config files to bypass the apk crash-loop ...
[Nexus 7 Android Development] breaktheblock:
I downloaded mine on Linux mint then used usb-otg.

I wonder if the file system of the usb stick is making a difference? However the ROM flashed ok with this same stick.

As mentioned previously there isn't a web browser in this latest ROM provided by AnDiSa so I cannot do it this way.
[Nexus 7 Android Development] asmalldharma:
He wants to flash f-droid so it's a system app. I did it on mine and it works great.

Did you download the apk and try to flash it in twrp or did you download the ota file?

In case your haven't seen this, here's how to do it. https://forum.f-droid.org/t/f-droid-as-system-app/2445
[Nexus 7 Android Development] breaktheblock:
I think you are right about flashing as a system app.

I downloaded the APK so far with no luck.

I used twrp to put the APK in a directory accessible when the ROM loaded but it couldn't parse the APK.

I have not seen the link you provided. The forum poster links to files which are old but these should work.

Can I ask I'm still confused what is the difference between the fdroid and fdroid privileged ota's, does one compliment the other? What is their purpose?

TIA
[Nexus 7 Android Development] asmalldharma:
Definitely old. It should update on its own once you install the ota file. I think the privilege file is just for older versions of Android that had less streamlined permission access. You could try it without that and see if it works. It's been a while so i don't really remember whether I did that part or not.
[Nexus 7 Android Development] breaktheblock:
I ended up flashing 1001050 this works thanks.

Although the fdroid app seems to take a long time to update it's thumbnails, understandable if its always like this, but just wondering if its my grouper.

Also on fdroid I downloaded an updater app that downloads Spotify, however when it installs the downloaded Spotify app it it says it isn't compatible!?

Thanks again.
[Nexus 7 Android Development] asmalldharma:
Some apps won't install on rooted devices. Magisk (another twrp flashable zip) should let you hide rooted status from certain apps so you can run them.

You should download from xda. I don't think the magisk site that comes up in a Google search is legit
[Nexus 7 Android Development] breaktheblock:
I will flash Magisk and have a go.

With fdroid I'm also getting 2 black columns (in portrait mode) over app descriptions, same in landscape but one horizontal black box which changes size when scrolling.

I know this sounds odd but has anyone else experienced this, crucially with this ROM?
[Nexus 7 Android Development] asmalldharma:
Has f-droid itself updated? My most recent version is 1.7.1.
[Nexus 7 Android Development] breaktheblock:
Yes using 1.7.1

I also put latest Magisk, used hide Magisk and chose the installer app but no luck, it still says not compatible. I'm not having much luck.
[Nexus 7 Android Development] asmalldharma:
Only other thing I can think of to try is download the Aurora store from fdroid. It's a front end for the Google play store that basically creates a fake account so you can download apps directly from Google. Then use that to get spotify on your device. I tried it on mine to make sure it works.
[Nexus 7 Android Development] adrenochrome25:
For Spotify just go to apkpure website or apkmirror and be sure to select the arm7 version.

The installer app you mention is just downloading the APK and installing it, you should be able to find the APK in the sdcard directory, if you have to give root access to something it's to the downloaded file and not to the installer app.

And you really should get mixplorer from his XDA thread so you can start an FTP server, or connect to one or your computer, use cloud, file sharings ... to avoid the problems you already encountered with intermediate otg cables and usb storages. And it's vital for many other things like accessing the system files with root access or using his integrated text editor :)
[Nexus 7 Android Development] asmalldharma:
I couldn't find spotify on apkmirror. I only found references to a takedown notice.
[Nexus 7 Android Development] thomas2403:
If you want to use FDroid as system app, install the apk as usual and then install the magisk module F-Droid Privileged Extension Installer. That worked for me. You have reboot after installing the module.
[Nexus 7 Android Development] Flounderist:
Sorry for being OT, but I cannot put on charge my device anymore without rebooting it first.

Anybody already faced it?
[Nexus 7 Android Development] breaktheblock:
When I flashed the ota zip it said on the notes that privileged extension was included. Anyhow fdroid was accessible after booting onto the rom. And it updated itself to 1.7.1. so seems sorted :good:

---------- Post added at 09:50 PM ---------- Previous post was at 09:44 PM ----------

I have gone for aurora in the end for a simple solution. It worked.

The overall goal is to run the tablet without it rebooting constantly but as I don't know how to log and report things im trying out not using Google play. I will test and see how I get on :good:
[Nexus 7 Android Development] danibus:
Hi there, I'mn testing this ROM, at first sight seems very nice but very low space available (around 1.8GB)

I read about deleting system partition in 2nd post but not sure how to do it, maybe not necessary.

I have unlocked device, before installing this rom I had android 4.4.2
[Nexus 7 Android Development] mikeataol:
I am not at all clear what you mean... Space where? /data partition?

this is how the file system looks on mine.
