  • The Pixel 3a is a practically perfect phone.

  • A pinnacle of photographic prowess, with a value that predicates panic among more painfully

  • priced phones.

  • It's also phenomenally preferred among people who like to pinch pennies and pay profoundly

  • less.

  • A prerequisite to purchasing though, is to politely, pragmatically, and painstakingly

  • pry open the Pixel to pinpoint any potential pitfalls.

  • Let's get started.

  • [Intro]

  • The trick with opening up the Pixel 3a is to know where to put your pry tool.

  • With a little bit of heat the screen comes off first, and will most likely break during

  • this process...if it's not already broken.

  • The safest of the unsafe places to start is up at the top, between the glass screen and

  • the first plastic lip, since the fragile ribbon cables are down along the bottom of the phone.

  • After the adhesive at the top is cut, I can work my way down each side of the phone with

  • a soft piece of paper or card stock, because if anything touches the display underneath

  • that glass, it will shatter.

  • It's a dangerous operation.

  • Lastly, after getting a small gap, I can use a bit more heat and carefully take the same

  • piece of paper and slice through the adhesive holding the bottom portion to the screen.

  • Then the whole thing can lift off, exposing a single ribbon connector under this black

  • piece of tape.

  • The ribbon goes through the mid frame to the motherboard underneath with only 2 t3 screws

  • holding the little silver bracket over the single Lego style ribbon cable.

  • This could very well be the easiest screen replacement of 2019.

  • With no other steps involved, it's a super simple way to fix the most often broken component

  • of a cell phone.

  • Nice work, Google.

  • The Pixel 3a is much more repairable than the more expensive Pixel 3.

  • There are 14 more of these same t3 screws holding down the mid plate.

  • I'll link the tool kit I use down in the video description.

  • The metal mid plate is probably what kept the Pixel 3a from snapping in half during

  • my durability test.

  • Once the screws are gone, I can now pry into the second gap between the black plastic lip

  • and the purplish plastic of the phone.

  • Then the whole thing pulls away from the phone body with just the top front earpiece attached

  • to it.

  • We get our first glimpse at what looks like a very complex inner workings of the Pixel

  • 3a, but it's actually not that bad.

  • Let me show you.

  • The battery connector is underneath the side squeeze sensor ribbon.

  • I'll unplug that and then pop off the extension ribbon, just like a little Lego, on both ends.

  • Then I'll unplug the right side squeeze sensor, and the left side squeeze sensor.

  • Does anyone actually use the squeeze sensing functionality?

  • I kind of forgot they existed until now.

  • There is good news about the battery though.

  • It has magical pull tabs, signifying a very easy battery replacement...that is, of course,

  • if you don't break the pull tabs like an amateur and have to commence the Pry of Shame.

  • I, of course, would never break a pull tab on accident.

  • I only do it purely for educational purposes.

  • The battery is a 3000 milliamp hour capacity and does allow replacement by dogs.

  • You can see how the left over pull tab adhesive pulls away from under the battery.

  • See?

  • Education.

  • Next I'll unplug the side button ribbon cable and our little friend the headphone jack.

  • The jack does have a little water damage indicator on the bottom.

  • This phone is not water resistant, so if it does get wet, the sticker will turn pink,

  • avoiding any warranties.

  • Underneath the motherboard we have one little ribbon cable for the rear fingerprint scanner,

  • and two wire cables that run down along the left side.

  • The motherboard houses a singular 12.2 megapixel camera unit, which does include optical image

  • stabilization.

  • This is supposedly one of the best cellphone cameras on the market right now, but I'll

  • let the other tech YouTubers compare the actual photo quality.

  • We're here for the hardware.

  • The front camera is an 8 megapixel little guy with no optical image stabilization.

  • No thermal paste or heat pipe on this plastic contraption.

  • Down here at the bottom we have 3 screws, one on the board and the other two on the

  • sides of the USB-C charging port.

  • This crazy little board has the ribbon connector for the charging port, and it's own white

  • water damage indicator sticker and a microphone.

  • The USB-C port has no rubber ring around the tip, but it is super simple and easy to replace.

  • I'm a huge fan of the modularity on the Pixel 3a.

  • If you want a cheap, easy to fix phone, with features like a headphone jack, this is a

  • great option.

  • The bottom loud speaker for some reason is very securely attached to the plastic frame,

  • but is pretty large and has it's own gold contact pads to communicate with the motherboard.

  • The last interesting thing to come out of the Pixel 3a are the side squeeze sensors

  • hidden below this long plastic rod for the electronic buttons.

  • The squeeze sensor is embedded into the side of the phone, and is made up of little resistors

  • that are sensitive to being flexed...even sensing something as minor as a squeeze on

  • both sides of the phone.

  • This activates an app or a camera.

  • Pretty crazy technology.

  • Lastly, we have the neon power button.

  • It's plastic protrusion is held in place by a little black flap.

  • Not as ingenious as the buttons on the Nintendo Switch, but with the long black plastic rod

  • holding it in place, I have no doubt it will do it's job well.

  • I

  • It's been a few videos since I've put a phone back together in working condition.

  • I've had to break open the OnePlus 7 Pro and Red Magic 3 to get access to the heat pipes

  • under the screens.

  • But this Pixel 3a should go back together just fine.

  • Getting the fingerprint scanners and two side wires attached to the underside of the motherboard

  • is pretty much the hardest part.

  • Then the whole thing can flop over underneath it's little plastic latch, and I can situate

  • the headphone jack back in it's slot.

  • One screw holds down the motherboard, then the extension ribbons, squeeze ribbons, and

  • battery ribbon all get plugged back in.

  • Then the mid plate can come down and hold everything securely and structurally in place

  • with it's 14 screws.

  • The easy to replace screen gets plugged in next to the motherboard through that mid plate.

  • A brand new screen would probably come with it's own adhesive, otherwise you can just

  • use thin double sided tape.

  • And that's it.

  • A fully functional Pixel 3a.

  • I'm a fan of where Google is headed with this one.

  • A phone that accomplishes all of the essentials while keeping money in your wallet.

  • What do you think about the Pixel 3a?

  • Hit that subscribe button if you haven't already.

  • Come hang out with me on Instagram and Twitter.

  • And thanks a ton for watching.

  • I'll see you around.

The Pixel 3a is a practically perfect phone.
