Lag after updating stock or custom ROM - Nexus 6P Q&A, Help & Troubleshooting

Has anyone else experienced that as soon as they update their device (either stock ROM via OTA or just a dirty flash) that their device slows down considerably? I'm not entirely sure why this is, but it always seems to happen. My phone doesn't run nearly as quickly, and I cannot figure it out. Is this normal?

You can try clearing the cache and if that doesn't speed things up flash the vendor image. The latter usually speeds up my phone after I flash an update for some reason.

Lower the 3 animations scale options in Developer Settings...Mine are .5x and have smoothness on custom Roms.

[Q] Newer ROMS crash/freeze

Hi! When running ROMs that are "newer" such as 2.2 ROMs they crash/freeze for no apparent reason. With or without an SD card in, everything wiped, newly updated recovery etc etc.
However! When i run a ROM like Kimera 1.8 Cupcake ROM it all floats on perfectly.
I cant see any rhyme nor reason behind the problems im experiencing. Any thoughts? It's really killing me :/
Could you define "crash/freeze" a bit more specific please? Does the phone boot up as normal?
If it just hangs on randomly when using the phone normally, it might be a ROM specific problem (not neccesary 2.2), maybe some app who can't handle 2.2 just yet, or you configured it badly (overclocking?).
As riemervdzee says, more information required.
What ROM are you trying? What radio? What CPU settings if available?
I tried SenseHero (2.1), Froyos and currently running Fusion!ROM 2.2 and they all run perfectly on my G2 Touch (Hero)
It boots up perfectly but then either reboots after random use or just freezes in the sense that i use some app or scroll through the app list or try to make a call and it simply freezes up and is unusable until i remove the battery and reboot.
I am running FROYO_2.2.1_Special_Edition_RC1_update1 and as far as i can think of i haven't configured it anything specific. Is there perhaps a way to reset every setting such as CPU setting etc that might be wonky?
Im running 63.18.55.06PU_6.35.15.14 Radio!
lol i love you're definition of "newer roms" when you've only used 1 rom.
first i'd recommend trying some others. i'm not saying the one you tried is bad at all but it may just not agree with your phone for some reason.
Having said that - if I were you i'd check exactly what you're wiping - it sounds to be that you haven't cleared the dalvik cache or something (i.e. you've not done a full wipe before flashing a new rom).
My new bie guide has the process for flashing a new rom (part 2 i think).
I've run a myriad of roms, im just stating that this is the one im currently running and experiencing problems with.

What exactly is the problem of running an other 2.2 ROM? It could be a ROM specific problem, which frankly occurs at your phone (egh, sometimes happens ).
If you are sure you wiped data, dalvik, cache and ext2 (if any) I really suggest you move to another ROM and see if that one works OK.
I experience exactly the same problem with every 2.1 and 2.2 ROM so i doubt its ROM specific. I've wiped everything. Im quite clueless in this case what the problem might be!

[Q] U8800-official 2.3.5-rooted-random reboots

Updated to official 2.3.5 rooted, added back the pink screen, not done much else except installed a few apps.
Getting random reboots while phone is sleeping. Never happens while actively using phone. My phone will be on my desk and next thing I know it restarts.
Anybody else have this problem or found a solution?
I need to find out if it is the rom or something else causing the problem so I can start to troubleshoot it.

Turn OFF wifi when you're not using the phone. problem solved
If not work try this :
Goto CPU menu -> smartass v2 and make low and high cpu speed settings to 1 ghz.
This will also increase Battery life and must fix random rebooting.
Other way is clear caches and install rom again.
Loureiro:
I'll try turning off the wifi. It sounds like a highly likely solution since: 1) I've only seen my phone at home 2) I always turn wifi on at home.
Is there a specific reason why wifi is causing reboots? Maybe something I can find a fix for?
technogod:
Don't have custom kernal installed, so I can't alter the CPU parameters. Wanted to make sure the phone was stable at stock before changing the kernal.
Speaking of which, what's the most stable kernal for overclocking the 2.3 stock rom?
I'll try clearing the caches as well.
Thanks.
The wifi bug is known fault with the .35 kernel found in the official upgrade. hopefully it will be fixed next week fingers and toes crossed. I am not sure if any of the kernel dev's have found a fix yet.
Without cpu parameters, only way i am found that : clear three caches with clockwork and reinstall your rom. It's working on stock roms or custom roms. I think, this is not rom problem. There is different something. Cache clearing solves problem. Resetting problem started on my phone when i start to try other roms.
I am using miui 2.2.3 now and i will setup 2.2.10 version today. While using stock rom, i have some resetting problem. But now, my phone working without self-reset.

What's The Best Way To Revert To 4.3 & Block OTA?

I just updated to 4.4 yesterday, now battery life is horrible and tethering is broken. This is the weakest update I've seen since I moved to Android with the N1 launch. Other than the boot animation and a slight boost in wifi speeds I'm really not seeing any redeemable qualities in Kit Kat. I want to go back to 4.3 and block the OTA. What's the best way to do it? Is there any way to stay really close to stock rooted and do that? I'd prefer not to use any highly customized and buggy ROMs but if I have no choice I'll do what I have to.
Any suggestions?

I'm no expert but surly this would be a case of using something like Wugtool kit and revert to stock, then simply unlock the bootloader and flash a custom recovery this will block the update.

I was already rooted and had a custom recovery on stock 4.3 but read that OTA would still be applied unless a custom kernel was installed or other major differences. I also couldn't tell whether the OTA will just fail and not be applied or if the error encountered would fubar my phone.

as long u have custom recovery, the ota will still popup but no install, if i remember to block ota popup u need custom kernel
edit: the error on ota install would háppen b4 the ota would do anyting to the phone.
you do know that you can not judge battery life from one or two of the first battery cycles with a rom, right? first boot is when the device does most of its syncing, and you will get the worst battery life. not until the 3rd or 4th battery cycle will you actually see what the battery life is really like. and tethering isnt broken, the default tethering option works fine. third part tethering apps could be broken in 4.4, until they fix things.

I'll give it a few days on the battery unless it's out of control. My biggest concern was that it was charging at a slower rate. For the first 8 hours it couldn't do more than maintain current charge level while charging with my MBP. It seems to have overcome that now. I checked usage and couldn't see any heavy syncing.
Many thanks on the tethering. I was using stock tethering but couldn't get any traffic to get to the phone or past it but DHCP was working. After reading your comments I tried again, this time with another Android device and it worked. I want to say I had a similar problem before tethering a Win8 system so I will investigate that more.
Thanks again for all the replies. Really appreciate it.
Update
I thought I was OK with KitKat until I saw the stock email app had been updated to look just like the awful Gmail app. K9 won't work with my exchange accounts so after failing to get the earlier stock email (4.1) to work in KitKat I went back to 4.3. After a week I got nagged by OTA alerts. For others in search of a fix for BLOCKING OTA UPDATES ON THE NEXUS 4, I BLOCKED OTA UPDATES by following this great thread http://forum.xda-developers.com/showthread.php?t=1998378
I installed FOTAKILL, changed permissions, wiped the caches in recovery and renamed the otacerts.zip in /system/etc/security/ (using ES with root and mounting system with RW - plenty of other ways to do this) and no more hard update notification that you can't swipe away. There's a service manager you can try out also but reviews seemed spotty - read the linked thread for more info. Best of all I can use my phone and not be forced to use $h!tShat and I don't have to spend hours researching ROMs and kernel combinations and their respective bugs. Hope this info helps someone else. I couldn't get any hits searching for fixing the OTA problem with the N4 but the Nexus7 instructions have carried over to the N4 pretty well.

MDOB rom messed up S4 (full wipe doesn't wipe everything?)

System Specs: Galaxy S4 Canadian i337m OTA 4.3 (jfltecan), carrier is Bell, stock Samsung firmware, stock kernel (use wicked rom 9.1 sometimes too)
WARNING:
lot's of reading so go grab a coffee and have a cigarette before you sit down to read this, you'll probly be here for awhile
The rom/fix in question: MDOB rom/i337m fix - here's a link to both.
http://forum.xda-developers.com/showthread.php?t=2280556
first off i'd like to mention this phone was 100% perfect on stock Samsung rom 4.2.2 using Ktoonsez KT-SGS4 kernel for many months, until the day I installed this dreaded MDOB 4.2.2 rom and the "fix" that came with it
everything went bad on me back while I was running 4.2.2 stock unlocked boot loader and could never get it back to normal so this isn't a issue caused by 4.3 knox or 4.3 itself that i'm currently using. (i'm stuck on 4.3 roms but had this issue way before 4.3 existed)
i'm having an extreme amount of issues AFTER installing the MDOB rom, even after changing rom back to stock (flashed back to stock rom with ktoonsez kernel which is what I was using before I installed MDOB rom and phone has been royaly screwed ever since that day) more specifically I think it happened from the "i337M fix" that's included with the rom, either way after installing this rom I've never been able to get my phone back to normal.
everything runs fine except until I install a custom kernel (Ktoonsez KT-SGS4 kernel) then all hell breaks loose.
I don't blame the kernels or my current rom since I've ran this before for many months until the day i installed MDOB rom on my phone my phone was a dream machine.
issues since this rom has been installed include:
Issues:
A. RANDOM SLEEPS OF DEATH (phone shuts off or freezes)
B. random freezing while trying to turn on phone or enter recovery
C. some kernels won't work proper (specifically ktoonsez KT-SGS4 kernel) example gpu stuck at max while idle and downclocking when screen is touched with this kernel
D. wifi won't work with custom kernel on stock 4.3 rom without build prop edit to ro.securestorage.support, although it should
E. weak wifi and mobile signals
F. bad battery life
G. bad call quality
H. More that I can't remember off the top of my head
here's my flashing process, in attempts to remove as much as possible:
I know a few of these steps are probly pointless but hey can't blame me for trying.
step 1. enable usb debugging & unknown sources
step 2. install root & recovery
step 3. fresh boot phone let files settle so they can save (5mins or more) then plug into computer while turned on and delete everything
step 4. reboot into TWRP recovery (version 2.6.3.1) and clear everything, full advanced wipe, factory reset, format data than clear cache/dalvik afterwards just to be sure
step 5. remove SD card plug into computer and format to make sure there's nothing
step 6. install rom
step 7. (sometimes) clear cache/dalvik/permissions after rom install, although fix permissions seems to break my permissions rather than fix them or maby my permissions just break during flashing and I just can't fix them (haven't tested enough to be 100% sure)
i'm SOOO temped to try a full nand erase since i noticed there ARE still lot's files on my phone directory even after wiping, but i know that isn't a good idea;(
once stock kernel is back on my phone these issues are all gone.
Ktoonsez says it's not his kernel (used to work before, so i have no reason not to believe him), he says it's the rom well i'm on 100% stock Samsung rom (exception of kernel) and the rom was built to act the way it does so you can't really blame the rom so who do i blame??
until i went to go try wicked rom and flash back to stock I didn't realize these things were still on here, but now they emerge! wicked rom was giving me some (unrealated?) issue so i decided ima go back to stock so i flashed stock rom via odin (pc) and right away i noticed the 4G symbol, Samsung wallet, desktop not setup proper (no shortcuts) this ONLY happens when switching from wicked rom to stock rom on the first flash, i flash again everything looks how it should, and in order to get it to do this again i have to flash back to wicked rom and flash stock rom again and BAM it happens.
i knew my issue started on the same day that i installed this MDOB rom but after doing a full wipe and MANY "fresh" stock rom installs later i stopped questioning the rom and just lived with a crap phone that reboots itself all the time and has bad battery life, AS SOON AS I SEEN THE SAMSUNG WALLET bam it hit me like a truck, IT WAS THE MDOB ROM INSTALL.
UNLESS stock Samsung rom comes with wallet preinstalled and hidden on stock/wicked roms than the ONLY other way it coulda got on my phone is from the MDOB rom.
I can wipe/delete/factory reset/flash with twrp & odin on pc all I want, my roms are still messed up after FRESH installs. I believe there is still left over files from this rom/fix, I didn't think there would be anything until I noticed when i'm flashing from wicked rom back to complete stock rom using odin on pc I experience things from MDOB rom (while It should be 100% stock after odin (pc) flash, but it's not)
after the first flash from going from wicked rom back to stock I always experience the following "bug" i'll call it a bug since these things ALL HAPPEN AT THE SAME TIME: once I flash AGAIN all these symptoms go away until I go back to wicked rom and flash back to stock rom than right there after this first flash going from wicked rom BACK TO stock ALL these symptoms come back until I flash stock firmware AGAIN, a second time (even though I just flashed it)
Symptoms:
1. Samsung wallet appears in my apps (this was only EVER on my phone once, when I had the MDOB rom on my phone), this thing shoulda never somehow appeared back on my phone in any way shape or form after ditching the MDOB rom, but again is comes back after the first flash going from wicked rom to stock rom.
2. I get the 4G icon from MDOB rom (not the LTE icon I SHOULD have while on stock, when on wicked rom I have a little LTE icon with a tiny 4G above it, the only time I've ever had just a 4G icon (without LTE) like this is when I had MDOB rom on my phone (which is the only other rom I've run other than wicked rom and stock rom).
3. this icon ONLY shows up after the FIRST flash from wicked rom back to stock, once I install stock AGAIN than it returns to it's normal LTE icon.
4. now i'm not just *****in about an icon here, this is just a part of my problem (indicator if you will), when my rom is "bugged" after first install from wicked rom to stock rom my wifi works normal how It used too. but once corrected (flashing again) AND using custom kernel on STOCK firmware it breaks my wifi 100% broken until I use this little build prop edit fix, set ro.securestorage.support = true to false, bam wifi now working but the rest of my problems are still there (wifi used to work 100% on custom kernels and everything until MDOB rom touched my phone and left this "bug" behind)
5. when this 4G icon appears after this "first" flash back from wicked rom to stock rom I also experience something else, my wifi button works during first boot setup and auto enables itself and I have no issues with my wifi connecting (as soon as I see this toggle on I already know once my phone locks onto the network it's gonna give me a 4G icon and not an LTE icon like it should and sure as shiznit it does, as soon as I get my icon back to how it's supposed to be (LTE icon) all of a sudden wifi won't auto connect on a first boot anymore, never, 100% never. (back before installing MDOB rom I used to auto connect 100% of the time on first boot) like it does now only when it's "bugged" out.
6. apps are missing, when this "bug" appears there's no app shortcuts on the desktop of my phone by default after fresh flash like there should be, sometimes they appear on first flash once in awhile (some apps might not even be installed? or just shortcuts missing, have yet to verify)
7. it feels like the phone flashes way too fast (second flash takes longer, I think?) and more/all? apps get installed on second flash, and Samsung wallet get's REMOVED (how'd it even get there? other than bein left behind from MDOB rom, same with the 4G icon, that icon isn't in either of the two roms I use so how does it get there? and ONLY at the same time the wallet magically appears and the rest of this stuff)
8. when this 4G icon appears my phone seems to be great except for the fact that I know my rom didn't install properly since i'm still missing apps ect, once I flash again, apps appear, Samsung wallet DISappears, 4G icon gets replaced with LTE icon and everything is A-OK until custom kernel is installed, remember this is NOT the kernels fault as it ran 100% perfect for many months ON THIS PHONE until the day this MDOB rom was installed, and it's had these issues ever since.
some of the things I've tried:
- Countless wipes, including full advanced wipe, restore to factory, data wipes
- Ton's of fresh installs of BOTH versions of 4.2.2 - now doing same with 4.3 and wicked rom 9.1
- Tried wiping using TWRP and odin mobile (flashed mobile odin via TWRP, it works incase anyone didn't know)
- Tried flashing roms using odin (pc) v1.85, v3.07, v3.09
- Downloaded new copys of roms from new sources to make sure my roms weren't corrupted in anyway
i'll hopefully edit this post and get some pics up soon and simplify my text to help you guys better understand my situation and i'll also add a list of things I've tried to fix this problem when i have time.
any thought would really be welcome, there's sooo many of us s4 users with random sleeps of death, i'm sure if we could fix this it would help out a lot of S4 users.
thanks, dustin

Have you tried to flash the stock firmware in Odin. You can get it off the Samsung Updates site.
The guy who puts MDOB together generally makes great rom's. If everyone had the same issues then no one would use it... you really could have gotten a bad download, user error somewhere or one of many other problems.
With apps' just "appearing" are you certain once you log into your google account that it not set up to automatically start downloading apps ?

don't get me wrong, i'm sure it's a great rom but my battery drain was worse than stock so I went back to stock, I REALLY appreciate his hard work towards our community. I just dislike what it possibly did to my phone is all.
and I don't have issues with the MDOB rom itself, it's AFTER that rom has been on my phone EVERY other rom ever since then now has issues in some way shape or form, no matter what I do.
if it's user error I put down the steps on how I flash in OP, I dunno what's going wrong
i'm gathering screenshot's to better show my situation.
I am 100% positive GAPPS is NOT installing anything after rom installs (I don't connect to wifi until after setup is done spacificlly to prevent this from happening, my rom just flashes this way (only on first flash from wicked rom going to stock rom) once I flash again a second time my symptoms part goes away and I get the issues part of my OP
if i'm on wicked rom and flash to stock = symptoms listed above
if i'm on stock rom and flash to stock = issues listed above
I can replicate this problem all day long.
I've flashed his rom on and off. Never had the issue. The rom doesn't invade anything a full wipe wouldn't cure. If it doesn't full wipe then it's the recovery. It helps once in awhile if you Odin back to stock or even copy your sdcard contents and format your sdcard to make it fresh. read up on it first.

Also I recommend doing 9 wipes when swapping roms. It sound ridiculous I know but I do it and have never had issues.

Just odin back to stock and set if that clears things up. It should solve any odd problems. The thing with flashing rom's is that someone's issues cannot always be replicated.
Going back to Odined stock will take it back to factory stock then do a factory reset in stock 3e recovery and you should be fine

OP2 kernel problems, considering H2OS?

Hi all, I am new here. I was referred by a friend who knows more about this than I do. I think I understand how to get fastboot and TWRP, so that is taken care of already. Now the problem with my OP2 running OxygenOS latest version, everything stock, is that it freezes up after unlocking, and the whole phone is just terribly throttled at this slow speed for a long time. All inputs are extremely delayed, and touchscreen is nearly unusable after the lag begins. There are so far two temporary fixes I found: 1) reboot phone 2)wait it out/keep unlocking until it doesn't lag. I also have been unable to make a copy of my internal storage via USB, as it gives unspecified error during copying. And lastly, the screen dims on its own sometimes at random while anything related to auto-brightness should be off. Fortunately, I was able to make a hard copy of my internal storage thru some wifi file manager apps. Now my friend pointed out that my phone's issues could be related to a bad kernel. To remedy this, he told me it would be good to flash a new kernel onto my phone. I considered changing roms to CM, but apparently a lot of functionality is lost when doing this. He told me that I could retain Oxygen OS while flashing a new kernel, but I am not sure how to do this. I came across a post in the android dev section regarding hydrogen os, and I read that it performs better than Oxygen OS, but has minor issues of its own. I am interested in flashing this rom/kernel (I am not sure which is which). Here is the link in that section of the forum I found http://forum.xda-developers.com/oneplus-2/development/rom-h2os-hydrogen-os-ota-clean-stable-t3195636. I see it says that it is working on Indian OP2, and running stock rom and stock kernel. Does this mean that my north american OP2 won't be able to get this rom? Also if it is the stock kernel, does that mean it is the same kernel as the one currently installed on my phone? Anyways, if anyone knows about my phone's problems, or has a way to fix it let me hear it please. Thank you!

I had the same issue with O2. I changed kernels and the problems persisted. A also word the device and started from scratch through fastboot and the issues persisted. I ended up on hydrogen and I've never looked back. There is a flashable zip in that thread for the newest full version .11. Follow the steps wipe everything besides internal storage, flash the full v11 zip and boot the phone. After this reboot to recovery (power and volume down). Flash the gapps and super su zip if you want root. After this you should be able to add your Google account and be good to go. One thing I did was remove all Chinese apps and the stock launcher. I use trebuchet launcher from cm 12.1. Phone runs incredibly smooth now. I recently started running AK kernel as well. The oxygen version works with hydrogen. I have been averaging between 5 and 7 hours of SOT for battery with up to 8 if I'm just watching videos. Hope this helps. The ROM is a little simpler and the notifications settings are different. But you can set apps to have priority notifications and they function similar to oxygens notifications at that point. Everything is in the thread if you have any questions I'll try to help you.
