[q] really bad lag - Nexus 5 Q&A, Help & Troubleshooting

Hi, i have had my nexus 5 for about 1 year now. Over that last few months i have been experiencing really bad slow downs and lags for no apparent reason. This can happen randomly when doing certain tasks such as turning on my phones wifi or when there is low battery, or unplugging my device from the mains. This problem persisted in stock lollipop and in the cyanogen mod 12.1 nighties (which i am currently on). I do not remember having this issue in kitkat... When my device lags, i have to wait anywhere from 15 secs to 5 mins before it returns back to normal. i have tried factory resetting but this does not help... please help

Anyone got a soluiton- still have this problem!

Hi yes, it can happen at any time. In fact I was typing a replying and it just drastically lagged then...forcing me to do a reboot!

Instead of erasing partitions when flashing the factory img, format them.

Thanks for the reply...but what do you mean format the factory.IMG? I flashed via twep, and clear portions every time. I booted into twep and cleared the dalvick and cache but the problem persists!
Thanks

there is your problem, cm after some time of use gets really laggy, including system animations like nav bar buttons

Any solution then?

Nexus S button problems

For some reason after i installed the ROM Paranoid Android for my Nexus S and replaced it with Cyanogenmod 10.1, all the hardware buttons stopped working! I do no however that they are not dead because i can still use them in my recovery and in other places, just not on Cyanogenmod. Here is something even more strange, sometimes when the OS starts up the buttons kind of work for a couple of seconds. However, they slow down the OS a huge amount to where i think it froze. But then after some seconds i get taken to the lock screen, and the buttons don't work again. Any help is much appreciated!

Awesome! Thanks! :victory:
ARRRRGGGG!! It's back again except on the stock ROM! It seems every ROM i try all of a sudden freezes up for a second and then the buttons turn off. But when I flash another ROM it's gone for a couple of hours and then does the same thing! :crying: I also forgot to mention that i have a nexus s 4g

I'm using TWRP with no other mods or tweaks. But, what is clean/dirty flashing?
OK, i just looked it up on Google and I believe I have done a clean flash.

Dalvik, cache and data.. On twrp.. Everything except sd... is a full wipe/clean.. Go back to stock using Nexus root tool kit and start over, remember to flash in your recovery again as it will erase it.. Your sd should be fine.. BACK UP YOUR DATA FIRST (apps/other will be lost)
I'll get back to you if it works or not. Thanks!
Well after 3/4 of a day I have had no problems yet so I guess it's fixed! :victory: If something occurs i will tell you, but until then, thanks for all your help!

Swiftkey Issue

Anyone else having issues with swiftkey staying at default? I know there was an issue when you reboot the phone, the keyboard would reset but, it happens when the screen is off or the phone goes into deep sleep.
Was wondering if anyone knows of a fix??
Stock rooted ROM and kernel

Sorry cannot reproduce. Been using swift key every since i got the phone and not had any problems keeping it as a default, even after rebooting.
That happened to me on KK as well as JB. I simply disable the stock keyboard in Settings.

That's weird... You think GravityBox could be causing it? That's the only "modifications" I've made.
I've tried the official release and the new beta release and still have the same problems.

It could be as I don't have that Mod installed.

I think that reboot and crash happens in system apps...maybe the partition is corrupted?

What apps do crash exactly? Have you tried a factory reset in /settings/backup and restore?

Yep,did everything and no hope,now i realize that the screen starts to flicker a little bit before reboot,i hope that the problem isn't a wireless charger that i bought in amazon and used last two months,do you think will be a problem to RMA?
Thanks

constant random reboots

After one year with this phone I am starting having problems with it. The phone is almost constantly rebooting. Usually it reboots itself a few times in a middle of the loading screen.
I've changed multiple roms, wiped everything, the problem is still here. Same thing is if i reboot into safe mode. Random restarts, upgrading apps and so on.
Latest twrp.
Any idea ?
Change your kernel...or have you installed a new app recently?

Could be the power button going faulty like many on here have had

Have you tried a factory reset?

Tablet switching off randomly.

Recently my Shield Tablet, original not k1, has taken to switching off randomly. There is no pattern to when it does, can be partially charged or fully charged or with any app running. I am running Lineage official. Basically I will be using the tablet and I hear a little click and the tablet powers off. Any help would be welcome, thanks.

Custom ROM that could be a lot.
Maybe a battery issue.
Did you try a factory reset?

Perhaps a faulty SD card.
I'll remove the card and see what happens

Removed card, rebooted, and had the same problem within seconds so not the card.

I had the same problem once...
do you have TWRP?
what temperature it shows in twrp?
for me it was a wire from the battery that I had to solder on the right place again..

Yeah that is stopping me using stock as it reports a temp of 100,000,000 c! Had always worked fine with lineage/Cyanogen until recently and random reboots started

post #15 this was my solution for that Problem.
maybe you have 2 broken wires after all that time? maybe it could help if you start up with charger connected?
