[Q] Why is my xoom so slow???

hey guys, I got a refurbished xoom the other day. it was kind of buggy. My android market crashes every time i try to download documentToGo and a couple of other apps. Sometimes the browser just keeps loading and loading and does not show a webpage at all. my web browser closes unexpectedly a couple of times today. It is slow to read pdf files. It is kinda frustrating.
Is this because my xoom is refurbished? Or you guys are all having this problems. Do you guys have any solution to that? Thanks.

It may be slow because it's refurbished, but that depends on the other problems. As far as the market goes, it's crap since the latest update, it closes on me a lot, it also gave me a problem with downloading docs to go, it wouldn't load the permissions so I could download. Some pdfs are slow depending on the content and the app being used to read it. Sounds like your problems are with apps and not the system, if the problems are bigger then I'd try to return it.
XOOOOOOOMIN!

i think u might try root it n flash a custom rom on it.

Mine is also factory refurbished (with one stuck pixel, how's that for QA) and mine was running somewhat slow until I flashed the Tachi kernel onto it. I'm debating flashing a new ROM, but at least a new kernel and an overclock will do you good, trust me.

Thanks for your advice. Would you mind give a link of the ROM?

I was running stock rom with both tachi and rogue kernels for a while...and it was a tad sluggish still.
Since then I have flashed moray and its been pretty awesome. Lots of extra functionality and the ability to use stock clocks for gpu while still overclocking is great. No lag at all.
OP you can find this ROM in Xoom development under Moray 2.2.2

I like the idea of this rom but I'm not sure I like some of the changes it makes (primarily with the battery icon and other small nitpicks.) Can I change these easily?

I had issues with my refurbished one lagging a lot even after overclocking until I reset the governor back to interactive. Also, the new rogue kernel helped with a few other lag issues I was having.

I still have random reboots....

Will these ever go away on my nexus s? I have gotten them in everything from stock 2.3, cyanogenmod 7, stock ICS, oxygen, and every single ICS rom I have used. I understand some software bugs take a while to find but I have had this bug for over a year, will it every get a fixed? (Or is this not a software bug but an actual issue with my phone?)

Could be cause from UV settings if you touched them

Nope. I usually run 200 mhz minimum and 1200 max for my cpu. On stock I also ran stock volts.

Well, you're running an overclock... Try running without.
CM7 has a sleep of death/reboot bug, so try another ROM not based on CM7 too.
Highly recommend Oxygen 2.3.2 coupled with Franco 08.12.2011 GB kernel.

If you're interested in ICS ROM, give AOKP ROM and Matr1x kernel a try. It's rock stable for me. I just rebooted to flash the new build, but before that it lasted for couple weeks for me without rebooting. Link to AOKP ROM is in my sig.

There's your problem. Perhaps increase the voltage? Your phone may not be able to handle the frequency without extra voltage.
There should be no random reboots if you never touched anything kernel related. If so, then bear the consequences.
I've been using CM9 v2.2 for about 3 months now haven't overclocked or undervolted and haven't had any "random" reboots ever.

I'd highly recommend the Androxide ROM along with Air Kernel. I've been running this combo overclocked to 1200 without any voltage setting changes for a decent amount of time.
random reboot frequency - about once a week ..

I second that. Usually OCing requires raising voltages across the board. I use +25mV (arm and int). If you're suing a matr1x kernel that's even more reason to raise voltages, because afaik that kernel is undervolted by default.
Best of luck.

Thirding it.
If you are having problems then roll everything back to stock... its not good enough to say you have run every rom , yet fail to mention you OC. What other tweaks do you run? Deep Idle?
I'd bet if you flash CM9 with no tweaking it, it will be fine.

Or just about *ANY* rom for that matter. First ensure you can run it stable without OC, UV, didle, mods, themes etc then, by all means, go ahead and tweak to your hearts's content.

Overclocking to 1200mhz CPU only does NOT require extra voltage across the board, but possibly a boost at the 1200mhz voltage. Each frequency runs at a different, changeable voltage which has nothing to do with all the others. LiveOC, however, raises the frequency of each step and as such generally requires a boost in voltage across the board or thereabouts.
As for the problem the OP is having, who knows. Could you describe any specific things you've done, though? Full wipes (detail what you wipe), titanium backup restores, etc.
First thing i would be trying now is to do a full wipe (factory/data reset, format /boot, format /system), flashing either stock 2.3.6 or 4.0.3 and installing only necesseties and try for a week or so. If there are still reboot problems, describe them and hopefully i can give you some useful things to try. If you had this problem before the 1 year mark you could have probably gotten the phone fixed/replaced under warranty, though. If it is now over a year i'm afraid that's too late though.

Just for info:
ALWAYS on stock, unrooted, right now 4.0.3 OTA. Since 4.0.3 random reboots, w/o any culprit cause I can find..
So, I guess, has nothing to do with ROM, voltage, solar storms, etc..

Well this is all bullcrap. . . i installed CM7.0.1 and CM7 RC1 and the latest ICS from CM team and her phone either randomly reboots or switches off totally while charging in the night.
Its got bugger all to do with the kernel because i used the standard kernel with all the CM7 & CM9 roms and the same things happen over and over.
Also the OC'ing idea is BS, i don't OC my nexus S or hers and even mine suffers random reboots.
there has to be some code somewhere thats not behaving a sit should and google never sorted it and CM team never found it, or the hardware is just ****ty in this hand set.

Have you tried other ROM besides CM7? I remember when I flashed CM7 for the first time. My phone never liked it, it was all bugs for me. I even noticed that OC'ing would generate problems on any ROM.
I just ran away from CM7 and OC'ing.
Try Oxygen ROM (or stock as they stated before) with all set up to defaults and test for a while.

I admit I had reboots with cm7' but with latest cm9 nightly I have none. Stock kernel stock oc and stock voltage with deep idle off

The update was pulled for many reasons. Try stock GB or Oxygen ROM and enjoy life without freeze, sleep of death or reboot...

[Q] Alternate Kernel for CM11 M8

I am using the CM11 M8 on my Nexus 5. What Kernels are compatible with it? I have been a big fan of CodeBlue and ElementalX but I am not sure if either of these work with CM11.

All CAF Kernels work with CM11. ElementalX works with cm. It has both AOSP and a CAF version. You need to flash the CAF one!

ElemenntalX works with CM...
but there's some problem with min frequency, for me it got stuck at 1100mhz and its not changing

The min frequency isn't stuck. When you touch the screen, flar2 has set the freq going up to around 1200mhz so that there isn't any lag. If it's indeed getting stuck for you, you must have installed a kernel tweaker app which is causing this. Been using ElementalX since ages without a hitch.

Not sure about the kernel in question, but I've absolutely seen SlimKat's kernel do that. No kernel tweaker app, just system monitor.
It seems minor hardware variations can cause only certain people to have issues with certain kernels. Or if there is an issue in the code, can be exacerbated by hardware variations.

Oh I see. I've seen quite a few people who complain about this frequency thing in the ElementalX thread as well and most of them had a tweaker installed so I thought it's an end user's error. You could be right though, not all phones are made the same.

I'm using Latest Chaos nightly. Performance/Battery life is amazing to my usage, so i'm recommending you to give it a chance. ElementalX is good too, but you should try them both for a day or two and then deside which one suits you best. You can grab it there:
http://forum.xda-developers.com/goo...-kernel-chaos-12-0-nxtweaks-app-13-0-t2551441
It's CAF kernel, so it's compatible with Cyanogenmod. Happy flashing

I'm on the latest CM11 nightly with chaos kernel stable 13.1 and I'm loving it. Performance is awesome and I'm right on track for a 5 hour screen on time with heavy usage.

[Q] Lollipop Feels Sluggish and Slow

Anyone else feel like after the update the phone is running sluggish? All I have is stock lollipop with twrp, root and Franco kernel. Seems like my kit kat was faster.... Also getting high ram usage, like 1.6 gb...

might be your kernel. Stock rom+kernel combo runs quite fluid for the majority

yes, that's the combo i'm using right now and i see no lag whatsoever. I'm satisfied with stock that i even didn't speed up animations to x.5 , which i used to do on all android versions since Jelly Bean.
If you prefer custom kernels, i've had a great experience on kitkat with elementalX, haven't tried it on lollipop yet though.
I'm just saying that one of the changes you made is probably causing the sluggishness, it might not be Franco kernel, but that's a variable you can change for a start and see if there's any difference.

Yeh I tried elemental but I was getting poor battery life. Decided to try franco,seems like the same thing except unstable. Sped up the kernel to 1479 or something like that,seems to be a little better now. Let's see I guess.

the stock CPU clock for each core is 2.26GHz, so 1479 (1.4GHz) is quite a notable underclock, no wonder you are getting sluggish performance. it's like you have activated battery saving mode all the time.

Lollipop is a lot of things but sluggish is certainly not one of them. I'm running N5X which is an AOSP build of 5.0 and it's pretty great. Using the stock kernel with it, I don't like using custom kernels anymore.

It was set to 700 earlier which was even worse....seems to be a bit better now but I think I might go back to stock.

lag?

just got my oneplus over the weekend and i notice most of the custom roms have alot of lag for me. no matter what mods, tweaks or kernels i flash. the scrolling mod fix did help but i just don't feel the device is very smooth coming from my htc m8. any suggestions or thoughts?

More information about your set up. How and where do you experience lag would help.

Yeah this would really help.
My bacon setup. is really fast with zero lag (better than the M8), so I am not sure what setup you have right now that would be causing this...

Scrolling lag. Opening and closing apps. Just overall sluggish. Right now im on mahdi rom with the auxx kernel. Stock speeds. Zen + smartmax. Tried many other roms and configs. Was even worse when i was on the ak kernel. The only roms that dont lag are the alpha 5.0 roms.

Do you do full wipes between ROMs, and did you have this lag on CM11S before you started going custom?

Yeah that is really odd, I mean I get nothing but smoothness on this phone with pretty much every ROM I've used, currently on the latest Carbon nightly...

My device also lag so much, to the level when there can be 2 sec delay when I scroll on home screen with nothing open (only Google apps installed). The weird thing is when I first got the device is seems ok, then flashed 5.0 Alpha and then a couple of other ROM like PA 4.4.4 and then back to stock. Now even on stock (100%), I am still getting so much lag it is unreal. Some other issues: sound breaks when watching youtube, and sometimes screen freezes and phone reboots.
