systemui not responding and other instability

Hi guys,

First off, let me say that this ROM is great when it's working OK.

Just wondering about the stability others are having with this ROM. For me, it's completely unpredictable. It goes from blazing fast, to lagging, to just plain frozen without even being able to turn off the screen all within a few minutes.

I simply don't understand how it can be so hot and cold.

I should mention that this device was pretty horrible with the stock rom as well but that was a bit different because it was consistently horrible. Now, it is amazing sometimes and horrible others.

I'm basically ready to retire this device. I've tried different kernels (m-kernel, lean) and I've tried tweaking just about everything I can think of.

Any advice?
[Nexus 7 Android Development] pellajl:
The advice I can give is to be patient and hopefully an Android V5.1 of this ROM is released.

Android 5.0X has some real problems under the hood. I suspect it is memory management issues which Google seems to have largely addressed in V5.1.

If you install the stock V5.1 on the Nexus 7 2012, you will notice much more consistent performance. However it still a little laggy but use able.

If you Google "Lollipop performance", you will find hundreds of complaints about performance issues after the upgrade particularly Samsung devices.

I hope that helps....
[Nexus 7 Android Development] ljjehl:
The team is already testing new builds of 5.1. Its only a matter of time. I for one, already have 3 devices running like a boss!
[Nexus 7 Android Development] eelco_akker:
Settings, Developer Options, Windows Animation Scale, Transition Animation Scale, Animator duration scale all Off, Background Process list : At most 3 processes. For me it helps a lot
[Nexus 7 Android Development] fonnae:
That advice was simply amazing. I really think that setting should be mentioned on the front page of this thread. Tablet runs so much better now.

I actually only needed to set background processes, and to 4, at that. Turning off animations was helpful too but not really needed after.

- No more lag when rotating the device

- No more lag/freezing when opening a new app

I actually used the tablet for more than hour of app switching, browsing and video watching with no problems. I have experienced a couple reboots but that could be that I never used the device enough to get one before....could also be overclocked kernel. I'm very happy regardless.

:D
[Nexus 7 Android Development] Dai323:
Wow! This actually made a massive difference for me as well. Thanks for the tip!
[Nexus 7 Android Development] zuke24:
I just flashed my grouper to the F2FS variant of this ROM, and it actually works really well for me! I do seem to have some problems with the headphones jack now (it randomly disconnects even when it's not physically disconnected). I've worked around it by using my BT headphones.

However, I'm using a OTG cable with charging capabilities that has been reported to work for other people with a grouper. However it doesn't work for me. Even the OTG capabilities with this cable don't work.

Updated to Stable 2.0 Build 2

Just uploaded build 2 for stable 2.0. Overhauled ambient display, added ability to toggle heads up notifications, added density settings and a few more stuff. Fixed setting lockscreen shortcuts resulting in UI force close loop, notification tile longpress and few more bugs reported after releasing the last build. Some fine tweaking here and there has been done as well.

Please leave feedback, press like or thanks and donate if you like our work so that we can bring XenonHD to more devices and pay for our servers, etc.
[Nexus 7 Android Development] adomol:
Flashed XenonHD 2.0 just a few hours ago for the first time. Everything looks to be working great so far... camera and gps seemed to be an issue on a few 5.x roms, but they are working here. Nice work on the kernel too, it's good to have the f2fs support for data/cache built in. I think I'm gonna flash this up on the 1+ as well.
[Nexus 7 Android Development] player911:
Never mind. Wrong thread
[Nexus 7 Android Development] Da Avenger:
doesnt seem compatible with franco kernel

Installed the 28.4.15 build (ext4 partition) oviously clean wiped ...worked fine ...flashed franco kernel (the one compatible with stock 5.1 i suppose) it got stuck in a bootloop ..is it not compatible with this rom?
[Nexus 7 Android Development] kalafior12:
Can I flash f2fs version as a secondary rom on all2fs (system,data and cache) primary rom?

Please prepare for us 28-04 fullf2fs version too. Many thanks :)
[Nexus 7 Android Development] carlfinity:
Same here, got stuck in a bootloop. I guess it is for stock based 5.1 or something. :/
[Nexus 7 Android Development] paintba11er89:
Same thing happened to me. TWRP version 2.8.6.0. Couldn't get Lean Kernel to work either. Any thoughts as to why this is? These kernels are reported to be working on Chroma and other 5.1.1 ROMs.
[Nexus 7 Android Development] harry_fine:
Did full wipe clean install. Thanks to those who support this.

Only bug I see is that under Settings --> Storage --> USB connections I click on the USB connections but it doesn't take me to the options.
[Nexus 7 Android Development] iceandfire:
Connect it to a PC and try again.
[Nexus 7 Android Development] Dai323:
Mods please delete. Accidentally posted.
[Nexus 7 Android Development] RastaFATian:
do Libertunas gonna make a f2fs of the new version of the rom?
[Nexus 7 Android Development] adomol:
The rom is already compatible with data/cache f2fs.
[Nexus 7 Android Development] RastaFATian:
so i have to format the other partitions like system in ext4?
[Nexus 7 Android Development] adomol:
The rom will format system to ext4 when you install. You only have to make sure you have data/cache f2fs.
[Nexus 7 Android Development] kalafior12:
You know, there are fullf2fs fans :) ( like me)
[Nexus 7 Android Development] FerrarisIV:
I am on the old F2FS Rom and i just downloaded the new version.

Which steps i have to do?

Simply restart in Recovery Twrp

Wipe data and cache

Install Rom (zip file)

No conversion from f2fs to ext4 ?

[Nexus 7 Android Development] webdroidmt:
Thanks for the new build! Nice nav bar additions including a power menu button, which is always one of my favorite features as it reduces wear and tear on the hardware button.

I am completely at a loss of what to do. I wiped and installed. Now I am having issues where Google Play will not load up. It will pull up for a brief second and then close out. I have had to use the default browser to download the things I need but without Google play, it makes things harder to do. It doesn't even crash. It refuses to load up. Never encountered this issue before and I have been installing roms on multiple devices.

So can anyone help?

(Yes, I searched this thread, and read multiple FAQ's but no info)
[Nexus 7 Android Development] pellajl:
This may or may not be the issue.....

I was playing around with the SlimLP ROM for a while and one of the strongest rrvommendations was to install a very cut down version of GAPPS where only the essential Google apps are flashed initially and all other apps would be downloaded later as required.

When I flashed the initial ROM, I used the full GAPPS package and I had all sorts of issues with Google services and Play. The theory was that during the flash process, a lack of available memory caused some of The GAPPS apps failed to install.

When I first flashed this ROM, I was surprised to see the GAPPS package was so large and wondered whether I would have the same issue - I didn't.

You may want to try the cut down version of GAPPS and see what happens. You should find the cut down version on SlimLP thread.

i am trying to install this on my nexus 7 wifi, i downloaded the 5-6-15 grouper, and in twrp i factory reset, flash xenon, and reset again, and it hangs on checking network window just past the wifi login. if i flash the 4-29 grouper, it all works except i cant get any working gapps. my searches havent turned up anything that helps, any advice?
[Nexus 7 Android Development] abdulhamid1978:
Same here, stuck on checking network. Fixed by using different GApps.

ok, flashed just xenon and it works now, can someone point me to working gapps please?

My tablet had the blinking screen when you have a notification bug with the new build. My first Xenon Lollipop build, so I can't speak to the other versions. Dirty Unicorns doesn't have that issue. Just FYI.
[Nexus 7 Android Development] puckshock:
A friendly reminder to always nandroid backup. I dirty flashed the new 06.05.15 build and ended up with a bootloop so had to wipe everything. This was with system ext4 and data and cache f2fs. Other than that seems much smoother after a fresh wipe so all good!

I ended up using the Mini Slim gapps from here http://xdaforums.com/slimroms/general/gapps-official-slim-gapps-trds-slimkat-t2792842

You need to use the Mini Gapps. When using these (151MB) I have 18MB free space in System. Any of the larger Gapps packages will be too big.

If not, does anyone here use another customer kernel, if so, which one and what do you use to tune it?

[Nexus 7 Android Development] ronin688:
Just wanted to thank inceandfire and libertunas for the great work.

I was ready to go buy a new tablet after a few years of worsening performance but I decided to finally unlock/root/flash and go full f2fs. It took me a while and I made some mistakes but learned from them and managed to get it setup just perfectly and I can't believe the difference. I'm running a pretty lean gapps as I use it mostly for reading, surfing, gaming but I'd say pretty confidently that it's faster and smoother than it was when it was brand new.

Thanks again!

theoretically f2fs gives you more speed, but using this rom it's not necessary - at least for me - because this rom is very fast without f2fs.
[Nexus 7 Android Development] Harpratap:
This is the only ROM for grouper that does not have that annoying lag/hiccup when installing app from playstore. I thought it was because of slow hardware, but this ROM managed to fix it. Swipes on keyboard are instantaneous like a new flagship.

Although, I'm facing few issues with the kernel. The min frequency seems to randomly jump (I use kernel auditor or trickster mod). This and M-kernel are the only ones I face ghost touches with (maybe a hardware fault, but plenty of other roms and kernels don't have this issue). Battery backup is also not good, its similar to stock.

Nice ROM, among best within 5.1.1 I tried (clean flashed). Only problem is that MX Player, don't work properly (movies skips, freeze and auto restart in the middle of time in hardware and software decoder mode). I have appropriate AC3 and Tegra3 codecs installed.

Seems to be kernel or ROM related as google stock 5.1.1. works fine with latest MX Player.

Can anyone else confirm this MX player behaviour (try to play movie at least 5+ min if problem occurs).

For now I have changed from MX to VLC, but also VLC only works in software decoding mode (but not with hardware decoder mode...I get error after few minutes of watching movies in xvid, mp4 format), but at least without problem.

Any tips toe MX Player or maybe different kernel that works with XenonDH?

Thanks button pressed!

I clean flashed 20150624 a few days back and so far I agree with most of the comments, it has revived my Nexus 7 back to a usable device again, but every now and then I'll recheck the Background Process Limit setting when the N7 feels a bit laggy and it has reverted to Standard.

Is there a way to make the Background Process Limit settings stay on what's selected?

Anyone else who has adjusted this setting experience the same?

---------- Post added at 08:15 PM ---------- Previous post was at 07:58 PM ----------

One thing I have noticed is that despite selecting English Australia in the initial setup, the system always shows USA date format. I've tried adjusting in MoreLocales2 and Locale More to no avail.

It's not a dealbreaker and I'm guessing it's not the dev's fault. Just a bit confusing for non-US (ROW) users and a rather frustrating after how many years of being ignored as a locale by Google.

Downloaded, wiped and installed. Runs great.

QUESTION

Can I under-clock this newer version? A lot of my wife's time on the tablet is spent reading books, doesn't need fast process and better battery life would be helpful.

If not the bundled kernel, is there any other that people recommend that I can install over this ROM that will let me under-over clock?
