going to buy a nexus 7 what defects to look out for?

[MrProph]

hey all ive seen multiple thread with people complaining of dead pixels ....and i think screen lift? what is that exactly?

what else should i be on the lookout for and pay close attention too? thanks

If you just get a protection plan, or notice anything within the return period you should be ok. I'm sure anything irregular would be noticeable. And when in doubt just return it. I got mine at walmart, they offer a 2 year protection plan that also covers accidental for $30. Can't beat it.

Sometimes ignorance is bliss. What one sees as a defect another would not. However it is your money and if you're not happy you have every right to return the product.

The screen lift appears mostly on the left side where the glass is raised and higher than the side frame.

Screen lift
excessive light bleed
dead pixels

Those are the ones I've seen, and I'll continue to look for 'em when I get each replacement.

Screen lift is the most common defect, it seems to always be on the left side (when held in portrait), look at the device side on and you may see the screen come up above the bezel, and have a look at the other side for comparison.

please don't look for any non-obvious defects. we have too many people inspecting with microscopes that give the nexus too much hate that it deserves. your screen is not gonna pop out on you so just enjoy this amazing device and spread the word

People keep saying "microscopes" and I think it's a unreliable generalization of those that have seen issues with their devices. This one I just exchanged for today, didn't even need any "microscope", or a close look at all. You can see the screen lift at a distance that you'd normally use the tablet. I have it right now at an arms length away and can tel that half of the glass on the left is raised above the frame, while there is some still flush. Dead pixels are the same.

Two problems i'm most familiar with:

Screen lift - A millimeter or so of screen lift. A popular theory is that one of the screws is too long that when screwed in tightly it presses the screen upward and creates a lift

Axis crossing between two touch points (affected me) - When two touch points have their axis overlap the two points begin to flip flop and behave erratic. This is a very minute issue where quickly overlapping these touch points (vs slowly) can easily be ignored. Most likely a hardware grounding issue. Affects many people but in reality it wont make a difference as it only occurs in very specific conditions. Problems goes away if the tablet is being held (grounded by you) or placed on any other surface that can act as a ground.

Quick youtube videos can show these problems being demonstrated

If you use a headset, there is no microphone connection on the 3.5 plug. The only way to get external microphone input is with a bluetooth headset!

Don't look for problems just enjoy your device.

Most of the tools you'll need to properly check for defects are available on Harbor Freight.

#1. Precision machinist's micrometer ($62). Be sure and check all the way around the entire exterior edge at increments no more than 1/100 inch apart. Note all measurements. If the largest measurement is more than 1/1000 inch higher than the lowest measurement, IMMEDIATELY return the device. You could have screen lifting (or a hair).

#2. Precision level, machinist specialty ($45). Place N7 on a level surface. Be absolutely SURE that is level by pre-leveling using a larger precision level to check absolute flatness of the surface using Harbor Freight Precision Contractor and Engineering Level ($142). After proper leveling of initial test surface, make sure that N7 is at room temperature (Harbor Freight precision infrared remote temperature sensor ($89). Temperature of N7 should be within .0007 degrees (F) of room temperature in your home measure at no less than 12 spots in your home, no less than 12 feet apart. In mama's basement, you may measure 4 positions 3 times. Place precision machinist level on surface of N7, and take readings at 1 degree increments for the full 360 degrees rotation of the device. If readings vary more than 2 degrees in any TWO segments, return the device immediately!

#3. Obtain a portable UV LED light from Amazon (sorry, Harbor Freight doesn't have these, but they're cheap from Amazon anyway) $29.95 with free shipping for Prime members! Cool N7 to precisely 41.7 degrees (F) by hosing it down with a can of Dust Off held upside down and allowing the propellant to cool the device, and measuring with Harbor Freight Infra-Red precision remote thermometer. Turn off all room lights (yes, even the lava lamps!), and throw the cat out of the room (they have high body heat). Immediately turn on the UV light from Amazon and check for any inconsistencies in the fluoresced patterns/colours. If you see ANY difference at all, IMMEDIATELY return to Google and request a replacement.

If you do receive a replacement from Google, IMMEDIATELY execute all of the above approved tests, exactly as before (you already have the tools now) and return again if there are any variations on supplied test datum. Do this until a unit (preferably one with a C120 serial# precedent) passes all tests. Then you may load up apps, enjoy it, and then blow it up by rooting it and beg for help with your now bricked N7.

Orrrr, you could just do as JD914 suggested above.

Just me or is this whole post a little excessive? I mean, it's a $200/$250 device. Making sure specs are perfect all the way to the thousandths of an inch is absurd. Besides, like I mentioned before for half the price of that micrometer you can get 2 year insurance plus accidental from walmart. Work smarter, not harder.

Um, you do realize that post was a joke, yes?

I picked up a new C60 16 gig at Wal-Mart today. Excessive screen rise along the right side. Went to a new Office Depot and downgraded to a C60 8 gig. It has a micro rise along the right side but it doesn't creak or pop so I am just going to live with it as long as it doesn't get worse over the next 14 days. No C70s around here even with new stock that arrived in the stores today.

OMG that's freakin hilarious!!! LMAO well done!

There is no rear view camera.

This. I finally got a C120 with a rear camera.

Mine came with a blown speaker and the glass lifting issue. Was exchanged for a new...

I've personally experienced display separation, light bleed and dead microphone. I haven't had any dead pixels, but plenty of others have. I've also heard about washed out displays and banding on the display.

If I were you, I'd strongly consider some other tablet. The hi-end specs of the Nexus 7 aren't worth the horrible quality control of the hardware in my opinion.
