Nexus 7 on Cm 11

Hello guys, I currently own a nexus 2nd Gen it's rooted and running the latest cm 11 nightly build. Sometimes it make a buzzing noise while I'm listening to music or watching videos or it froze and restart itself that happen at least 3-4 times a day. I was wondering if that happens anyone else and how to fix it

I've never had the buzzing but I don't use the speakers much.
The freezing and rebooting I have had both on stock and cm11. Best uptime I'd get was ~24 hours.
After flashing the latest Glitch kernel it's been up for ~106 hours. All location services turned on, syncing, google now, same apps etc.
Too soon to tell I guess but definitely an improvement.

I thought I was the only one it's getting really annoying, other roms are fine

I sometimes have buzzing sound for a short period of time. But I am using stock rooted 4.4.2.

I get this too, also happens in games

happened to me only on stock cm11

I ask this everywhere but does OTG work with latest cm11 nightly for flo? It is important for me since I cannot flash any other kernel to get it working

Can you tell all your glitch kernel settings?

Buzzing Noise fix
Flash the stock Android 4.4.2 ROM back on your Nexus 7 and the install Xposed.
Why would you need a custom version of 4.4.2 on your tablet that's already running 4.4.2 when the Xposed Framework works just as well.
EDIT - I've had no problems with buzzing noises or freezing on stock rom with unlocked bootloader and rooted.

Yup - same here. I've actually experienced this on both CM 10 and CM 11. The audio distortion out of the speakers is horrible. CM roms are the only ones that have this problem. I wonder if it has something to do with DSP Manager that's included with the CM Roms??
I agree with previous posters in this thread too - Stock rooted 4.4.2 is all you really need. Been flawless on my N7 2013.

I have the same issue
It usually happens when I watch a video from youtube or twitch. My tablet buzzes like kind of similar to someone getting an answer wrong in a game show.
I just need to go back to stock.

Can confirm that there's a buzz sound and a 1-3 second freeze using the CM11-M2 build.
After flashing the Jan 24 CM11 build, and the glitch kernel (using all stock settings except overclock to 1.7ghz cpu and 500mhz GPU), buzz sound is gone and all is well.

It happened to me with latest cm nightlies, and with all of them I had freezes and hangs. I went back to stock rom with elementalx kernel and i don't have any of these issues. I think cm overall is less stable and faster than stock rom. it's good for non nexus devices, but with nexus is better to stick to stock. I've tried other ROMs as well, nothing compares to stock in performance and stability.

Glitch kernel + cm nightlies = awesome mode
Still have more than 30% battery left

I have a problem with play store. It doesn´t load all the app images. Some of them are just blank while browsing apps.
I have tried latest nightlies, clearing app data and I have even tried a factory reset and I am still experienceing the same problem.
Anyone else having this problem?

Nexus 10 lags with every custom rom

Hey,
I got my N10 about 1 Month ago and it ran really fast and smooth in the beginning but when time went by it got slower and laggy. So i rooted it and installed CM11. There I had lag in the launcher, so i couldnt even scroll smoothly through the app drawer. I had the same problems with ThunderKat, AOKP ... The only time it runs without lag is, when i flash an original factory image. Then it runs smooth for like 2 days and it begins to become slow again.
It really pisses me of, that my N10 only runs fast when I have stock unrooted KitKat installed.. I thought its Hardware is more than capable of making the Device run smooth.
Has anyone an advice for me, how I can make it smooth again? Or which Custom Rom runs lag free for them, because I prefer Custom Roms over Googles Stock rom.
Sorry for my bad english and thanks for all answers.
Regards

I try not to make it my business to suggest which ROM is better for reason x or reason y so I won't, but I will say that you should not be having lag issues on most ROMs, even stock as this device can handle a lot.
That being said the issue more than likely lies in some bad apps you have installed, this or some mods that have been made that are working against you.
My n10 is actually my wife's so I don't mess with it much, but I will say there rarely is lag if ever on it. Currently I have her running the latest slimbean for the past few months and I'm sure eventually I'll put KitKat on there for her but she is more than happy with the performance as of right now.
So start by looking into apps that may be causing lag as with the limited info here I assume this is your issue

I get lag using Nova Launcher these days, it seems to have happened with recent updates. I have tried lots of different ROMs and kernels it persists across them all. Even the new GE Launcher seems slow.
When using apps I don't notice any lag. It is just a launcher thing for me.

Same here but I also see some lag in scrolling in apps like xda and Facebook. But that's normal. It still works great for games and apps though my brother completely destroyed my battery. I can only get like 5 hours now and the standby used to drain 1-2 percent a day now drains that much in an hour. Sorry went a little off topic there in the ned

Hi,
When my tablet started feeling really laggy I fully formatted it, installed stock KitKat, and then installed CM11 with the KK GAPPS, so far it's quite fast and performs really well. You may want to search for then"perfect ROM" for you, I can only tell you that I'm using CM11 and having a good time with it. Also using NOVA Launcher instead of stock, the launched that came with it indeed lagged a lot.

I would sugest you to wipe everything including the system partition then install a light and smooth rom such slim Kat and then some kernel. I use kt manta with a good tweak and finally activate trim

I have had good luck with the Franco kernel and CM11. The device runs very smooth and battery life has been outstanding. Just installed the GEL and have no lag issues. It is no nexus 5 but it's acceptable.

Okay, thx for all the answers. I'll try it out!

I'm really not happy with performance?

Hardware is fantastic, its let down by software. I will be honest on 4.4.2 performance wasn't that special either. I came from a Moto G, a phone with 1GB ram and 1.2 Quadcore CPU and performance wise it beats the S5. I upgraded to lollipop and well things have just got worse. For instance pressing the gallery takes 3+ seconds to open, same with making a call, and quite often when I hit the home button it redraws which indicates RAM is getting used up and needs free'd.
If you came from something like an S3 I'm sure this phone would seem like lightening, but coming from a stock android experience it is slow.
The question is how do I fix this? I did factoy reset after lollipop update which helps a bit but it soon bogs down again, an issue with 5.0 apparently. I have tried Nova which helps a bit but underneath its still running TW which I thinks the problem.

1)Use xtrestolite rom (free bloatware, u install only what u want..)
This is the most important thing I can suggest to you .. And flash rom fresh (I mean.. Wipe clean.. Etc)
2)if u want u can restart your phone once a day... IT will run a lot better after restart...
3)use performance governor cpu

This video has just demonstrated what I thought.
I mean how does this happen?

As mentioned above, nstall xtrestolite 4.4.2 if you want lag free, bloat free, optimized TW experience. You will get better battery, 0 lag and slowdown. It's simply butter smooth.
Don't go to TW lolipop because it's just not ready yet.
If you want to go an extra mile try CM12 based L roms like Temasek's or BlissPop variant. Pair it with ktoonsez kernel and you will practicaly have a new device.

Does anyone else's N910F lag?

Mine lags.
I use stock OC5 BTU rom.
I bought it second hand (just couple of months old) and it had knox triggered and with DBT OC5.
I had alexdr's OD2 multi CSC rom wasn't impressed with battery life so got customer recovery and installed deoxed rom.
Unrooted it to use banking apps.
Battery life was terrible so downgraded to KitKat BTU then updated to OC5 using kies.
I haven't done a factor reset after updating. So not sure if factory reset will help.
Battery life is still not very good but I can live with it.
Anyone also experience lags?
My Note 3 was better than this.

Yeah, mine does running SimplRom v3.2F
A lot of users have reported Lollipop lag- it just isn't well optimised for Note 4.
That being said, the one ROM that I've found has the least lag is SimplRom.
I'd recommend it if you're up for rooting etc.

factory reset can help out in a lot of cases, but stock firmware is pretty bad yes.
mostly it's because of all the junk samsung added, but also because they messed around with the runtime and some system apps (like SystemUI that causes a LOT of lag on the recents button)

Ah man. Hope they fix it. Specs are awesome and screen is amazing! But ui is full of lag and random heating up. Moto G is so much smoother

Hi!
I sometimes have recents button lag, sometimes up to 4-5 seconds.
I also experience app crashes several times a day.
Music playback (google play music is what I use) is chopping every now and then, consistently every few minutes. This is regardless of connected headset or bluetooth.
Everything feels so not optimized. I doubt Samsung has time to work on a Note 4 software update, now that they are pushing their new shiny S6 models.
Selling this and getting a LG G4.

Im not facing any types of lags or phone being heated up.Although while playing intense games it gets warmed up.Im running stock rom without root.All I did was a factory reset after the lp upgrade

I downgraded to KitKat now. Still lagging and stuttering present. Naturally had to factory reset with the downgrade. Battery life seems to be definitely better then Lollipop but still laggy as before. My phone can't be faulty can it?

My device doesn't have ANY FC. But I get TONS of lag with:
Photography (reviewing, and launching the camera)
Recent apps / multitasking
I am disappointed in the Note 4 for lags and poor camera quality in anything but superb lighting conditions.
Just might return it if Samsung doesn't fix these issues soon. I'll wait until the end of July, probably, and see if the update comes or not. If it does, and fixes, yay! If not, boo. And if it does come, and doesn't fix anything, double boo and never buying a Samsung device again. Shame on them!

Performance Degrades on Custom ROM

Hi!
Does anybody experiences degradation on performance after some time using custom roms?
I used some and the first days works like a charm but after some time performance seems to degrade, for example, someone calls, it begins to ring but it takes 2 seconds for calller image to appear and thats is one example. With rooted rom I dont have that degradation to the point I never restar my phone because its working fine.
Tnx

There is no perfect costume ROM.
think about it!! Even the performance of the stock unrooted ROM starts to get worse after a while of using.
This is the Tragedy of all android devices.

To be honest this stock rom, rooted, with xposed and some modules its been working fine for 3 months. I didnt restarted the phone and its working like charm. My note 4 its running with rooted stock rom and its working fine. My old s4 mini non rooted worked for years without wipe and now, without wipe my kid uses it to play and film.
Maybe I dont use the cellphone that much, I dont know but it works fine, never a reboot, never a wipe. The thing with custom roms its that they dont survive even 3 weeks. I dont know exactly where is the flaw but "normally" they degrade quickly and I dont know why.
I used Superman ROM for example. The rom its fine, fast at first but one week later it becomes slower, 2 or 3 weeks later you can see that someone its calling you but you dont see the pic nor the ringtone for some seconds and in time things get worse.
What apps do I use?
Wasup, maxton browser maybe once or twice a day, twitter once a day, simpsons game and nothing more.
I think its not the kind of use that can drgrade a ROM.
Maybe I'm missing something, maybe I have to do something to my phone to not loose performance (delete cache, etc)...

In my experience, the stock rom rooted or not, has better stability and least bug (if there is one) compared to custom roms.
Some Users prefer custom roms due to a leaner build and higher speed, but mostly these roms have one or more bugs that may annoy a User. This is understandable I guess for custom roms because they are not built by a professional team of software developers compared to i.e Samsung or LG.
