I've just changed the cracked screen on my nexus 5 and after fitting the new screen I've found that the frame rate has dropped to less than 2 frames per second (using fps test as shown). Apart from the frame rate being ruined the phone is perfectly fine. Does anyone know what could be causing this?

Are you actually observing that low frame rate? If your system was really running at less than two frames per second it would be nearly unusable. Could it possibly be a misreport?
Yeah the rate is actually that slow and it is near enough unusable. It takes so long to do anything on it and I can't watch videos on it at all, although when I record a video it is very jumpy but when sent to my tablet is completely smooth so the processor must be fine right?

Did you get an OEM Screen replacement? It could be that it's not playing nice with the GPU drivers. Have you tried flashing stock to fix the problem?
No it's not OEM and I already have stock installed. Do you think a factory reset would help?
Definitely sounds like a hardware compatibility issue. Not sure you'll find a fix.
That makes sense. I was worried that I'd somehow made a mistake when changing the screen and damaged the internal hardware. I've bought a Z3 as a replacement anyway and it's awesome, I'll get a working screen for the nexus as my backup.
Thanks for your help guys, much appreciated.

It's definitely worth trying a factory reset or using the stock images to completely redo the phone so you can see if the screen can work.
It may be that it's not quite a working replacement, though, in which case you can hopefully get a refund.
Yeah I will give that a go. I've already been offered a refund but I'll see if I can get it to work

I've read a few threads on the screen Flickering and there doesn't seem to be any resolution .
I'm on my 3rd tablet now (thanks best buy accident damage warranty!) And this one is flickering worse lately than ever. I updated to the latest firmware, yesterday only to boot up to horrible bouts of flickering during the setup screens.
The odd thing is, there seem to be no consistency to it. Some days it's so had I can't even use the thing, other days it doesn't happen at all. I use the tablet every day for notes or PDF viewing. I've used it with no magnetic cover (totally naked) and with the cover.. doesn't seem to change the occurrences.
I've turned overlays on/off force gpu render on/off.. nothing seems to fix it. Sometimes changing the overlay will reduce the flickering other times it doesn't affect it at all.
I hate to say it, but if I can't resolve it, I'm going to be forced to move to the surface 3.
I'm an electrical engineer and I've done as much trouble shooting as I can think to do.. but I've come up empty handed.
Anyone else have these problems? Has anyone found a definitive fix?
I sent mine back 3 times. The first was a reset. Thanks for wasting my time. The second was a motherboard and that didn’t do it. The third time they did a motherboard, digitizer, and usb port. It's finally stable and back to normal. After 5 trips back, the BB warranty triggers a new unit. Check if it triggers a refund.
I get it occasionally, so far I'm able to resolve it by booting into custom recovery (TWRP) and clearing dalvic to allow all apps to rebuild. Sometimes this resolves it for a few days, sometimes a couple of weeks. Its a repeatable "fix" that makes me question if the issue is related to memory or trim or something like that. Kind of reminds me of how with the first generation nexus 7s one would see slow downs after a while and filing storage with fake data then deleting it would improve performance for a while.
I'm definitely not a tender user of the device. I go back and forth between multiple ROM's and kernels on a daily basis testing what is testable, and unfortunately also what is not. Anyway, even though mine was bought as refurbished on eBay, I have never had any issues like the ones you describe. More specifically, I have never had any issues what-so-ever, that was not created due to my own ignorance. To me the device seems indestructible.
Besides, I would hate to be in the place of my device, or I would definitely have turned schizophrenic. Should I feel bad about pushing it through all this?
Because we're trying to figure out if it's related to a specific device type, which one do you have? P900, 905, 907A or another?

P900 wifi. Us version bought at best buy.
Today the tablet has been rock solid, I have literally done nothing between when it was flickering like mad and now.
I wonder if it might be related to some kid of data transfer. either over wifi, or when data is written or read from storage or SD card. I've take then SD card out to eliminate that as the problem.
Mine was P900 from BB
Issue lies with the screen.
This happened with me I sent it back to Samsung, 3 times. They seem to have finally got it right. They replaced the battery and then the display screen. Now it appears to be working I will let you know after a month if it is still good. They also told me that they will not replace the device even though I bought it and the issue was right from the start. Not even 6 months old. When working the device is excellent.
Ah, so now we know for sure the battery is replaceable. That's good news. Maybe someday our batteries will no longer hold a charge and we can replace it. Now for a good video on tear down and what tools to use to do that and where to get a replacement battery. I know it's early for most of us but someday......we will have to replace that battery. I'm one of those that keep my toys (computers/laptops/tablets/phones,) for many years.
Mine is running like new since last service. Getting the BB Geek Squad warranty has paid for itself already. I get 2 years on anything over $500.
Mine is a p900. I purchased from samsung website. Mine has been doing it fresh out of box. So bummed.
Ive had my 12.2 since march and it recently started flickering. It seems to tuen of the screen for a millisecond especially when lots of refreshes happen. Like scrolling a pdf. A few days back it was bad. Now it has gotten better and I havent noticed anything.

My P900 has just begun flickering exactly as you describe. So I should just be patient and hope it goes away by itself?
I'm flickering again. Turning the screen brighter is what triggers it for me. Returning to stock just to get it back and have it flicker again to hit the magic 5 returns may be what I have to do.

I just followed this guide. Its been a week now, not had any flickering since I did it.

Lifting the motherboard only temporary close the gaps of cracked battery connector. The permanent fix need to do: re solder the battery connector.
Look closely under magnified glass or microscope , you'll see the cracked solders. You can test by pushing the connector slightly, a bad one will move easily or lift off from its solder joints.
This video was removed from the poster after I pointed out his guessing solution. Flickering screen has nothing to do with LCD connector on the motherboard.
Lifting mother board actually you're applying pressure on the battery connector from rear cover.
I have had my P900 sent to Samsung service twice without having the screen flicker fixed. I thought this was a known problem and that Samsung themselves should be aware of it? Maybe I should supply some XDA links next time...

Depend on where you send for service, they know how to fix it now. Service Centers actually are contractors provide services for Samsung and others, the fact that most people don't know.
http://forum.xda-developers.com/showpost.php?p=59573206&postcount=100
It Works. Battery connector replaced. Smoooooth
After 2 visits to Samsung , my unit finally works fine.
Motherboard and LCD were changed first time. But issue persisted.
Second time, battery connector was replaced. Since then it has worked very very smoothly.

Hi,
Since today, my nexus became super slow. I have no idea why.
I already flashed a brand new Factory image, but even after that (+ wiping cache etc.) it's still slow as hell.
Even the boot animation is running @ 1 fps.
It's pretty warm to the touch, but not super hot, like to the point it would throttle like hell.
I'm currently running the Android M Dev preview.
If you know what this could be, please let me know.
Thanks!
First off, remove crappy apps and disable useless features.
If needed return to a more stable build.

There weren't any apps installed, and there still aren't on the Android M preview so that's not the problem.
Something very strange I noticed was that if I put some pressure on the bottom of the phone, it runs perfectly smooth...
You weren't using a Galaxy s6 recently were you? I was using one the other day and then I picked up my nexus 5 and had all same the problems you just described.

I have no idea why it does work when I press the bottom of it.. Could it be a loose connection, maybe..?
Aaaaaaaaaaand I broke the glass, AGAIN.
Broke the nexus' glass 3 times already in a year
It's probably a hardware problem. If you break the glass three times a year, than the rest of the hardware probably is damaged too. Using a case may help.

Well I guess it's a hardware problem then I'm not super carefull with my phone indeed, and I don't like cases. XD (Altough I have used one for 1/4rd of a year)
Let's close this thread. :good:
Description of the problem:
This happens several times in a day, but I have had a few days when this did not happen. When waking the phone it becomes super slow, like 1-2 frames per second slow. After rebooting- the recovery is just as slow. Sometimes the view is moved vertically up, the top part that is moved outside of screen and is drawn ant the bottom. Sometimes the image flickers. I have not noticed any pattern what stops this behaviour, it is just over after some time (5s to 2 hours).
What I have tred with no success:
Rebooting, clearing cache, factory reset, bringing the phone to full stock (http://forum.xda-developers.com/oneplus-one/general/tool-oneplus-one-return-to-stock-t2970390), updating to latest version, several ROMs and different kernels with each of them. After flashing any new rom the phone used to work fine for a day or two, then the stutter reapeared. Tried it without installing any apps- same problems.
I had to replace the cracked screen and the camera that didn't focus to far objects. The touchscreen ribbon is now insulated from the metal LCD back since some people suggested this might be the reason for touchscreen responsiveness issues.
It seems that the processes work normally, but the view on the screen is updated slowly.
What made the problem less bad:
I had applied a glass screen protector. Removing it increased the time between slowdowns.
Since I bought the phone secondhand and had tinkered with it I cannot get it replaced.
I have tried everything I could, now I need your help
Any suggestions?

Hi,
Sounds like a Hardware issue to me.The board ist mostly bad soldered. It can happen sometimes in the factory(not only at OnePlus, Samsung, HTC too), even if they test the devices before shipping.
Background: We had some germans around here had the same issue, they got a new replacment by OnePlus, OPO support told the customers that the hardware was faulty.
Can u afford another Mainboard for the OPO ? That will fix that issues for sure.
Well that makes sense I'll poke around to see if I can get one for as little as possible. So far I'd expect to spend ~250$ and that is just bad business
no worrys, u dont need to spent that much.check aliexpress or if your lucky buy a dropped OnePlus One on eBay. One with working mainboard. It will cost around 30-50% less than a single Mainboard would Sounds ridiculous but its true.
Anyone experienced this? Phones just out the box, got my apps installed and was testing the phone out. Screen splits and looks like it's overheating. Assuming it will have to go back for an exchange.
Get it replaced

Definitely not right. Take it back for a replacement.
Finally got the phone exchanged with T-Mobile, new one works fine but man does it get hot. I've had warm phones before but this one, especially during setup got so hot that I was worried about something internally melting. I actually shut it down till it cooled off then finished setting it up. I think whatever thermal throttling LG has setup for the phone is not conservative enough. I read where others have had concerns over the temperature this phone runs at and now understand those concerns. Heat is an electronics device enemy, this phone under setup or heavy use has a lot of them.
Most modern phones get hot now. Samsung Galaxy get so hot you can barely touch them when GPS is running. While I love the features these phones have, I'd sacrifice some screen resolution for better battery life and performance. Why we need quad HD screens this small I'll never know.

My V10 gets hot fast, even when just downloading or updating apps. My G5 doesn't get too warm really at all. It depends on the phone you get I guess. It sucks. A lot of people said their V10 didn't get hot, but here mine does. I guess it's just what you end up with. I WISH they all came the same or that companies would do a little more quality control. I've returned a lot of devices in the past for different problems but it seems there is never a "perfect" one.

Mine got the same issue after 4 months of having it. I have a rooted phone, so i can forget about t-mobile replacement. Any idea if it is a hardware or software thing? Should i get a replacement display?
Thanks

I would put the phone back to stock. Call T-Mobile and tell them what happened, I've exchanged Samsung phones that have been rooted and tho I've flashed back to stock knox was tripped and they have never said a word about it. It's clearly a hardware issue and rooting it can't cause that, I can't say if it's policy or not but T-Mobile has always been fair with me, I imagine if the issue was in somehow related to rooting they might say something but haven't ever with me, it's always been hardware so I can't say.
Here's what happened with mine
Called them, told them what's happening and I had to pay $20 for the exchange. I had ordered mine by phone so that's the route I had to take, they mailed a new one to my local store, I went to pick it up and they inspected my original phone for cracked screen, water damage or signs of abuse, they never even turned it on to check bootloader or anything. We swapped phones and I was on my way.
This should help you also, when I originally called in the rep asked if I could send him some pictures of the phone so he could put it on file should this become an issue, which I did. I sent numerous pictures and screenshots so hopefully the next in line doesn't have any issues.
@Ducter I'll give it a try. Thanks buddy.
Lost my T-mobile G5 to the dreaded screen tear just 2 days into owning it. I'm in Canada though so I'm probably screwed for a replacement.
How to fix LG G5 Screen Split issue using Heatgun.
Disassemble LG G5 using the link below.
https://www.youtube.com/watch?v=hveXdJLJEeU
Disconnect the Wifi Cable (Black One), Rear Camera, Front Camera.
Now with just the logic board, place it on a surface that won't melt.
It should look like the picture below. Warning don't take off anything else
https://imgur.com/a/gmp9Z
Turn on your heatgun and apply left right motion only concentrating on the cpu metal plate for around 15 seconds.
Do the same thing on the opposite side of the cpu plate.
Let it cool down for around 10 minutes.
Put it back together and it should work.
I did it atleast four times, first time it worked but failed after few minutes.
Second and third time was not working at all.
The fourth time I did it, it was working.
It's been a while and it still going.
Credits to the poster.

****please disregard. Figured it out. Looks like six screws holding in the logic board also.
Thanks for sharing. I went to the original post and thanked there also.
I'm stuck trying to remove the logic board. I can see how the front camera comes off very easily. I can't find anything that looks like a black cable for wifi. Also can't figure out how to remove the rear camera. Any pointers?
Thank you in advance.
My phone is dropping the framerate on touching the screen occasionally, stuttering for a short time. It is fine again after rebooting, but I am facing this problem since I got the phone three weeks ago. Does anyone else experience this? Is there a solution? I am worried this could be a hardware defect.
Try to reinstall the ROM. You can install full ROM without losing data. If that doesn't help, try a clean install.
Yes I see it too. In fact I started a thread on this in Q&A section but nobody seems to be interested
Nothing I seem to do in terms of tweaking the performance parameters seems to help. It can be fine for half an hour and then out of nowhere a few frames are dropped and it looks awful
It's ok 98% of the time but those 2% are making it hard for me to love this phone.

It sounds like a rogue app is taking control of your phone. I checked your Profile GPU rendering screenshot against mine, and indeed, mine never goes much higher above one-half length of the green line, which I think may be the 120fps limit (the green line itself is 16ms or 60fps.)
Seems to me that you need to uninstall some custom/rare apps to troubleshoot this issue.
It is definitely not normal behavior.

So my guess is that either people don't notice it, but I think that's quite impossible as even some kernel devs told me they wouldn't experience this. Or it's a fault in oos itself. Or we are using an app or some setting that's causing this. Or it's a kind of defect, which I think is unlikely but not impossible.
I am about to reset the phone completely to stock with msm download tool and start from scratch. Have you already done something similar?
Next idea would be flashing Omni ROM as I believe this is one of the most clean and fluid custom roms. If all of this fails, I would start to believe it's a hardware problem.

I would suggest you learn adb/ fastboot to do this so you learn to know what, how and why you doing this and that.
Not really difficult but extremly helpful if you face problems.
The large amount of applications and internet uses it may slow. Better cleared all caches and it's working properly.
