Exhaust - Nexus 4 Q&A, Help & Troubleshooting

Guyz is there any exhaust hole for heat emission in n4.
Sent from my Nexus 4 using xda app-developers app

I think the speakers and/or the camera and flash serves as the exhaust.

the glass back is meant to transfer heat out(thats why it gets warm with use, thats why its glass).

I notice that compared to other devices I've had the N4 gets very hot..

it actually doesnt get as hot as most devices. but you can feel the heat more, because of the glass back. if it was plastic/metal, you wouldnt feel as much heat. it just means that the glass back is doing its job right. my galaxy nexus and nexus 7 get much warmer, but it isnt felt as much because the backs are plastic.

Of all phones in household between original nexus s, sensation, hd2, nexus 1, one x+ and n4, nothing comes close to beloved n4 . Few times I'd to end call as its fricking hot in ears and hand. Good thing at least keeping us warm in UK's summer cold

Yeah, we also need to get it smogged every two years.

It's right next to the muffler and the catalytic converter.

Winter is coming. We should add anti freeze to the lube oil

Far as everyone mentioning the glass back, I thought glass was an insulator, not a conductor (something like aluminum or such would dispel heat, glass wouldn't necessarily, as it's an insulator).

Glass is a terrible thermal insulator. It is however a great electrical insulator! Ha

You mean aside from your USB port, headphone jack, edges around power and volume button, around the LED light, and speaker hole? Honestly I think people are making a mountain of a mole hill out of this, has anyone actually reported a Nexus 4 exploding in their pockets? (from overheating that is).
In any case if you're curious about the innards, check out this tear down of a Nexus 4.

I actually used to have a sensation and it didn't get nearly as hot as this phone does. Neither did my G1, My Touch, Vibrant, S2, or my wife's note 2...
Not a big deal but I could use the N4 as a heat source to keep warm in the cold... If it wasn't 100 degrees out that is

On my Gnex, you can feel the heat on the chrome part of the camera, which gets hot to the point that it feels like you'd get a little burn
Sent from my Nexus 4 using xda premium

No. LG suggests you drill several holes to prevent overheating as it is a VERY big issue for nexus owners. I attached a CPU fan to mine and it rarely hits 200°F anymore!

anyone one else feel 'dips' in the screen?

this seems pretty strange, but sometimes when I swipe my finger to scroll or during a game, I swear I feel like a dip in the screen. problem is I can never recreate it. I would scan the screen with my finger to try and feel for the dip, but never find it. this would occur randomly during normal use, so wondering if anyone else had this?
Is this a joke?
Sent from my Nexus 7 using xda premium
heh heh heh heh heh heh very funny ))))
Try rubbing your balls over the screen,there more sensitive so you can find that dip,I would also recommend having some porn running on it so you cover the dead pixels

No idea what you mean by a dip. Can you physically see anything?
Its obviously his skin folding under itself when he runs his finger down quickly. Then it unfolds and he feels a jump

Put one hand on the N7's hip, and then you'll feel the dip.

Or more likely a spot of grease/misc human slime and he perceives the increased movement due to lubrication as a dip lol.

Normal operating temperatures?

This phone gets hot! I'm at 103°F right now while charging with lowest screen brightness and just going thru xda and the web. Should I worry?

Phones always seem to get hotter while charging anyway
That's roughly 39-40C which is normal for a smartphone under constant usage and/or load. My Galaxy Nexus was around 38-39C whenever I used it for extended periods, that's nothing to be worried about.
My single core 1ghz galaxy s is AF 40° charging, browsing web and on xda. Your fine.

It probably just feels really hot because of the glass back, but as everyone has said, that's not too hot at all, pretty normal, especially when charging.
Thanks guys. So what temperatures should I look out for?
Sent from my Nexus 4 using xda app-developers app
Don't worry about it, OP. The phone will throttle itself to lower the temp if it gets too hot. In an extreme situation it will shut down. The engineers took care of this. It'll be OK.
You remind me of first time parents who boil everything before the baby can touch it. By kid number 2, they just pick the pacifier up off of the ground, wipe it off and pop it in the kid's mouth.

Hmm idk about that. My Sensation did get crazy hot when I used the Chichitec battery in it but when I switched to the Anker battery I rarely noticed any heat anymore. But this N4 seems to be up there, maybe a little more than I ever felt my Sensation.

Gap between top bezel and glass

Is this the way the phone is supposed to be? There's a small gap between the top part of the bezel where it meets the glass. I try to keep my phone clean all the time but there are quite a few lint pieces and grime stuck in that gap. The bottom of the phone is tight. Never dropped it. It is an RMA

As you can see the bottom is tight with no gap. The top has a big enough gap for dirt and debris and no way to get it out.

Definitely not normal, you should probably RMA again if you can't fix it by simple means like the one posted above

Not going well with my RMA. This was customer service response :
"Thanks for contacting Google. The*specialists*has informed me that the*gaps are to allow for expansion of the glass due to varying temperature and is an intended part of the design.
If you have any*further*questions please feel free to*respond*to this email."
Can some of you guys take some photos of your phones so I can send this robot? Any other suggestions?
Sent from my Nexus 4 using xda premium
Dude, I think even with photos, you would be hard pressed to change their mind. Cosmetic faults are always put down as subjective and not worthy of replacement. You should have told them that you were experiencing some technical fault i.e. frequent dropped calls.
If you aren't successful this time round, RMA it again with such an excuse...

I have the same issue but my gaps are much bigger and go throughout the whole screen. Dust and stuff goes in it. The front camera has a dark overlay whenever i use it due to all the dust that has gotten in there. I would RMA it but i bought it off a friend and im not sure if they want to accept it.
Here is a picture of a white door that i took outside using the front camera.

Its very dark and it has a weird dark overlay at the top.

Broken corners?

Well, I have a 3 month old nexus 4 and this week I realized this small marks in 4 of the corners of the phone.... I have been using the bumper from day zero and only had two drops from less than 20 cm high... Always with the bumper.... Is it a plastic soldering point? Is this normal? Is it going to break and explode?
Am I the only one having this marks?
I'm afraid of my phone falling apart....

I was really freaking out... I know the phone is fragile because of the crystal and all... But this is way too much... I really take good care of it... But it's normal to have little drops when you are handling the device 80% of the time you're awake...
Thanks for saying it's something normal, it kind of calms me a bit...

Back letters falling off

I'm just curious, has anyone ever gotten their Nexus letters at the back removed, as in the shiny black vinyl that covers them? The letters N, E and X were completely peeled off in my case in a matter of weeks when I was holding it, along with the adhesive.
Sent from my Nexus 7 using xda app-developers app
Nope, but I've had a case on it since day 1...:thumbup:
Odd. Hasn't happened to me. (Happened to every BlackBerry Curve 8520 I had, though. Damn, that phone sucked.)
Wonder if it's affected by how you hold it. Definitely return it anyway.
Wait, I didn't even know that could happen, I though they were like part of the plastic.
You got a picture of it?
Do you have a wireless charger?
I have one and I have noticed that after charging it is kind of warm on the back and I have to wipe some kind of stain around some off the letters. Now that you mention your letters falling off it gets me
thinking that the glue could be melting away or something.
My N7 is only 7 weeks old and I'm using a Fatboy pillow for charging.
Sent from my Nexus 7 using XDA Premium HD app
I had this same problem just a few days ago I noticed like a sticky residue seeping from the letters on the back and part of the letter lifting. I just removed all the sticker and cleaned away the sticky residue 'see attached pic' I actually prefer it without glued on sticky letters. Looks good I think.

I use the wireless charging feature as well - no issues, and it spends all night - every night - on the charger.
I didn't know that there was plastic in the letters to make it shiny. When mine finally fall out on their own, I think I'll get some model paint and paint the letters in white. Or maybe bright red. Just to be different.
Really? They fall? lol, I though they were pretty much part of the case :b

Yup, it looks like this. I was thinking about removing the rest so it looks uniform again the hollow letters do look nice, though. I don't own a wireless charger so I don't think that's the issue.

No wireless charging here either it's just glued on stickers that are losing stick over time as they heat and cool.
I'ts just like black tape.
Sure it looked cool glossy but doesnt bother me, I just picked out my letters with my nail and cleaned it up.
I like the 'indented' look nexus on the back.
What assembly dates do you have on yours? Perhaps they just changed to a less strong glue or even applied less glue due to the first batches problem of stains/glue residue.
