EEVblog Teardown - Nexus 7 General

Hi everyone. Just thought I would share a link to a good teardown video.

Thanks for the video link. It's a much more informative piece than the iFixit teardown. Interesting that there's a reset button that has been covered up. I downloaded the video for future reference.
BTW, love the dude's narration. Have to check out his video feed.

Edit: I'm wondering about the possibility of oxidation on the leaf contacts (which connect the three antennas) over time.

I love his video blog as well as his forum. I'm not sure about the leaf contacts... I know my HTC Evo 4g LTE has them for the antenna on the back cover as well.

That's an excellent video. Makes me feel like I know so much more about my nexus 7. More people in this forum need to watch this video. Google/Asus obviously went all out on this device. We see the proof in this video. They got top notch high quality parts for included stuff. I love the fact the battery is easily replaceable. Can't wait till 3rd. Party manufacturers come with their batteries THST will last even longer. The battery being easily replaceable is the biggest factor in increasing its longivity. Its easy for the user to replace. Even easier for Asus/Google techs to replace. Very efficient design. This is not some cheapo battery in here. Then the star of everything is likely the GPS/accelorometer integration in. One chip. This is a very high tech and high quality component. Worlds first and only 6 axis motion. Even has a built in processor for it. Then also dual mode GPS and glosnass reception. That component had so many great and complex features I can't even restate them all. Then by the headphone jack and mini or micro USB being separate, those are likely replaceable also.
What really interested was the possible reset holes he found. One being covered up. The other, on same side, right above 4 connectors, is another hole. Which is exposed and could possibly be another reset hole. Has anyone tried sticking anything in there to see if its one? Or will I have to be the first to try. What I'm hoping is THST its not a second mic hole. He only mentioned THST hole as a possible 2nd reset hole.
Brb, I about to see if it is one..lmfao. wish me luck!
Update: that hole is not a reset hole from what I see. I put something in there and pressed softly. Nothing happened. Pressed a little harder and still nothing. Kinda felt like pressing aagainst rubber as it had some flex/pushback. I didn't go extreme and really force something all the way. As it could just possibly be another mic hole and I don't want to punch a hole through it..lol
So the question now is what about the hole that's covered up by the case? If someone removes the back and test it out, they can confirm whether that one is a reset hole or not. If it is a reset hole, then we could easily mod/punch a tiny hole on the side backing to have it exposed and use when we see fit.

>So the question now is what about the hole that's covered up by the case?

I would tape the back cover before drilling, in case the rubber shreds (I doubt it, but to be safe).

I know I might get blasted for this but, I wonder if in the future there will be a way to buy a camera and plug and play it to work. I Remember the old Samsung vibrant had an open space for an ffc and we ended up being able replace the camera with a int'l galaxy camera and it worked. I just think a tablet of this size is still good for picture taking.

Love your bezel? Hate cases?

Why buy a slim, light phone, and slap a giant case on it? For that matter why did htc make the camera bezel stick out past the back of the case, so it gets damaged when you lay it down?

As a zero dollar remedy, I pealed a foot off my keyboard, restuck it under the camera bezel and viola! This one has been on my phone for two months now, and the last one lasted about six months. It keeps my camera off the table when I lay it down, and even prevents some glare from the overhead lighting. No damage to the case or camera, and no added bulk.
Htc inc redibly re-engineered
awesome! I personally would never do it but that's a cool idea

Dig it... Had I not already popped for my feather, I probably would have gone this route myself. Just can't stand putting such a svelte device into a behemoth case. For that matter, I feel the same way about screen protectors. /end rant

Shameless self bump.
I thought this was about the actual phone bezel when I read the title, cool idea though. I've always hated cases since most of the time they're bulky and ugly. I bought the phone I have because I liked the way it looked, why would I want to wrap it in something that hides all of that? I usually just take great care of my phone until it gets its first decent size scratch then I just say the hell with it and care about protecting it less. That's why I loved my OG Droid, I could beat the hell out of it and it would still look fine!.
I agree. The OG droid was a beast. This "mod" also fixes the wobble you get if you try to use the phone flat on a table.
Amazing hack.
If anyone else was interested in doing this and was looking for something less.... drastic... these clear feet would be perfect! (10 cents)
http://www.westfloridacomponents.co...+Rubber+Feet+Small+Bumpers+9.5mm+X+3.2mm.html
My bezel still looks brand new and I "carelessly" put it bezel down wherever I go. Now if some people put it onto the street asphalt then you're just.... yea.
And with your analogy why hunk another piece onto the back of it?
My bezel still looks good too, but I would cringe every time I heard it hit the desk. It is such a cool looking part of the phone, I'd hate to scratch it up.
This is clearly not for everyone. It did help me out, and I thought I'd share it in case it might help anyone else.
I think it is actually smart for manufacturers to let the camera protrude slightly from the back of the phone. Cameras have a minimum thickness that can't be avoided, but by keep the rest of the phone slightly slimmer (or as slim as possible), users can add a case without significantly changing the overall thickness of the phone.
If the camera were flush with the back of the phone, the entire phone would need to be thicker to allow it (of course, they could squeeze in a bigger battery).
The devil's advocate argument is that that manufacturers want phones that feel as thin as possible in your hand, even if they have to make parts of the device thicker for the camera (resulting in phones shaped like the Droid X).
Amen to that. I love my 8 megapixels.

LG 4x HD Fits the Galaxy S II desk dock! Plus my customcar install

I ordered a cheap desk stand from eBay, for the galaxy SII and the 4x HD fits perfectly!
I also customised a dock for my car, got fed up with trying to squeeze the phone into a rubbish looking universal mount, then connecting a trailing cable. So I hid the cables hard-wired behind the dash, and dremel'd the dock to shape, bent it with a hot air-gun, clamping it in a vice. Getting the connector to stay in place took a hot glue gun. (leaving a cavity underneath means I can still reach my headlight switch, not that i use it, I leave it set to on 100% of the time on the Volvo, as it makes no difference - the daytime running lights are set up to be the main dipped headlights anyway!)
I think now I've got a working prototype I'll buy another and redo it a bit neater. (The dock is only about £4 from china!) as the plastic has reacted a bit to the heat!
The dock is simply squeezed into the gap in the dash trim, it holds fine.
The phone jiggles a bit and it isn't angled towards the driver quite right, but it's fine, and certainly easier than having to fiddle the phone and charger in every time I get in the car!

look great !!! cool man ^^
I Should add, people have commented on two things - firstly in a crash it's going to fly out very easy and be dangerous (Though surely any cheap phone mount will also! Only something like a Brodit will hold it very securely)
Secondly (and quite worryingly!) Perhaps the charging socket will wear out from sitting wobbling around?
Nice but isn't mobile blocking your air-conditioning channel?
Sent from my LG-P880 using xda app-developers app
Yeah, but sitting in the flow of air wasn't a big deal for me. Most universal mounts mount onto a vent!
I since removed this! Firstly, the phone wobbles quite a lot - I was worried that the charging socket could get worn out.
Also, in the event of a crash it would fly around quite easily!
I now use a Clingo, but I modified it by screwing the tip of the ball-joint onto a Brodit base, so it's held next to my stereo
Hi, can you please give the url for the dock you bought ?
Thanks.

Wow!! what a creative idea, charging and cooling at the same time. Good job.
@Ben-B can you post the ebay link? looks like a really good idea for us 4x drivers. I assume ANY S2 docks will do right?

I have one like this: http://www.ebay.co.uk/itm/Sync-Charge-Cradle-Dock-Station-Charger-For-Samsung-Galaxy-S2-S3-S4-i9300-i9500-/231021608377?pt=UK_BOI_Electrical_Components_Supplies_ET&var=&hash=item35c9f5fdb9
Though I've now added a shim of card (taped on the back part with black electrical tape) to hold it at just the right angle.
Just to clarify, I'm just talking about desk stands here, the car cradle idea was just me bodging a desk stand, but I don't use that any more.
I doubt a real G S2 car cradle will hold the 4x, the width would have to be the same and I'm sure it's not!

DIY Nexus 7 Portrait Dock

Currently in the planning phase, only a rough draft has been made for it to show what it may look like when finished, it is not scaled or optimized correctly yet. The end result might end up with 4x speakers instead of 2 but that also depends on what type of speakers I end up using "I am leaning on Logitech ones at the moment".
Specifications
LED Lighting in the Nexus sign
1x 3.5mm Headphone Jack Female (front)
2x USB (back)
1x Mini usb (back)
1x 3.5mm Headphone Jack Male (under where you put the tablet)
1x Micro USB (under where you put the tablet)
2x Speakers (Might end up making them Bluetooth speakers to kill off that extra audio jack)

How im gonna build it is that I am going to submit the final design once completed to a rabid prototyping company and have them 3d print the shell out for me, I then will add the electronics that I will salvage from cheap devices and solider them together inside the shell.
If anyone knows how I can get that soft rubberized feeling from the back of the tablet please let me know, id rather go with that type of finish.
"My friend just gave me an idea on how that I might also be able to add landscape mode without modifying the design". Ill have to do a little bit of extra planning later on how I am going to achieve this.

If you use something like that, might be wise to *not* spray it on the inside of the dock where your tablet goes in. It might cause some unwanted friction against the Nexus 7.
Along with the drip stuff there are quite a few spray paint type texture paints you could try. The local big box store should have a few different options

Very cool design. I will certainly be following this. Have you picked out the company that would be prototyping this for you? I have an idea that I wanted to do myself but I couldn't find a company to do it.
I like this idea a lot. What I was thinking would be perfect for a shop/garage setup. Hope this comes together for you.

They make some impressive things.
Talked to a friend today about some design plans and he brought up the possibility of adding a few features such as making it wall mountable putting a rechargeable battery in it and a few other things not worth mentioning so I decided I am going to release the plans once completed so everyone else can build their own.
I'm doing this because of the amount of good feedback I have gotten from the 3d community I'm part of at deviantart.

Slight Design Change in RMA Nexus 4

I have one of the original N4's when they were released, yellow screen and defective charger. I got an RMA N4 and it looks like they added little nubs to the bottom. Just an FYI

What hardware revision? Boot in bootloader mode and give us the infoz!
It's nothing major. But the back plate can somewhat be more easier to remove.
And which country?

Sent from my Nexus 4 using xda premium
Interesting touch, and very smart actually given how many people had their backs crack just from temperature variations on whatever surface they put their Nexus 4 down on. Hopefully that lifts the glass off any surface a bit. Flip side is that looks like it'd be a fitment problem for most cases on the market already.
It's not to cool down the glass, is to keep free the sound from the speaker that was getting blocked when you had the device on a flat surface.

They probably have a whole variety of reasons. IMO raising the speaker off flat surfaces would be a perfectly good reason because it's completely muffled when you put the phone down on its back. They wouldn't change the hardware just for that, but it'd certainly help.

Torx screw you mean.
And going back on topic, if the phone is flat on the table the gap could increase air flow for better cooling and increase the volume too.
Its REV 11, Production date 02/2013 made in Korea. i'm in the US and It still fits perfectly fine in the LG Bumper. The photo is little confusing it was taken with my original N4 with a macro lens. the hole is the torx screw on the bottom.
Awesome! I ordered an RMA last night, should be receiving it sometime this week.
My Nexus 4 died on me Sunday night. Red light of death
Watch as dozens of people cry about their phones not having this, and then come up with excuses why they need to rma their device.

Magnetic Charge/Sync cable

So it has already started, people are loosing and damaging their cradles already. This is going to create a need for a new cradle or another way to charge and sync the unit.
Ever since I first opened the box to my gear I wondered WTF Samsung was thinking with this cradle. There has to be a better way, and hopefully I have found one.
On the back of the watch are 2 small screws. My goal is to use 2 tiny magnets to hold a cable to the back side of the watch via these screws. This will make the cable MUCH smaller and no longer require a massive case to be carried around.
Current status:
Contacted a few companies and have a few different connectors coming in to see what will connect best.
PCB design will all depend on the connector we go with
V1 case design is already started for the housing. I will be printing a few samples out with a makerbot in a week or so and will post up
I hope to have an entire v1 test unit done within the next week or 2. I would have this done earlier but I have a massive fluid mechanics midterm tomorrow then will be heading out of town for the rest of the week for work. I should be back in town on Saturday and will be sitting in front of the makerbot and a soldering iron all day. Please stay tuned for updates.
Also all criticism is welcome, tell me what you think, the only thing I ask is to make it constructive. If you think this is a stupid idea because it will not work for some reason, let me know and why. I am a mechanical engineer with a concentration in structural analysis. I know only what I have taught myself about electronics so I admit I dont know as much as many others.
***UPDATES***​
10/31/2013
Currently working on getting sync capabilities working. I have a feeling Samsug did 1 of 2 things
1. Chip requirement like apples cables to allow sync
2. Power on data line
Either way this weekend I should be able to get the sync feature working or at least have parts on order to do so. First run on the spring loaded contact pins were pretty good, but I am going to need something longer. Once the case goes over the PCB board they will no longer be able to connect with the back of the watch. Here is what I am working with at the moment.

Points for effort !
Got the 1st set of spring pins connectors in. They work but will not be long enough once a case is designed for the unit. Back to ordering more $0.08 1/16" pins!
Try to check the thread
http://forum.xda-developers.com/showthread.php?t=2493181&page=5
Pins which You found seems to be very nice and will work well, but regarding the magnetic mounting - check if the screws are magnetic - if they are stainless steel (which they almost for sure are) they will not be magnetic... so this will not hold... the other issue is if the watch has sensors inside they may not like the strong magnetic field...
Can't wait to be able to buy one lol

Depends, not all stainless steel is the same. Depends on the blend. Some are quite magnetic.
