Phone (3a) Series brings a host of upgrades over the Phone (2a) Plus, so what better way to visualise those than to lift the lid and see some of that new hardware. In this post, I'm digging into Phone (3a) Pro in Grey. As you probably already know, smartphones are built in layers, almost like a sandwich, so let’s look at the 3 biggest components before focussing in on the internals that fit between them. ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2025-03-17/1742206524-435299-nothing-phone3a-product-teardown-02-large.jpg "banner") **🔴 Display** On the front of (3a) Series you’ll find a FHD+ AMOLED flexible LTPS display. At 6.77” this is our largest to date, delivering a 91.43% screen-to-body ratio. With an adaptive 120hz refresh rate for smooth scrolling and a 1000 Hz touch sampling rate (+316% faster than (2a) Plus), Phone (3a) Pro brings near instant responsiveness when gaming. There are improvements to brightness too, with 3000 nits peak, (3a)'s display is up to +131% brighter compared to (2a) Plus. Just like the (2a) Plus display, you can see that the rear of the screen features a large heat spreading copper surface. Near the top you’ll spot the selfie camera and proximity sensor cutouts and the slanted square cutout near the bottom is for the in-display fingerprint sensor to see through. The long black flexible printed circuit (FPC) is how our screen receives a display signal; it trails to the top of the device via a hole in the midframe and connects to the motherboard. **🔵 Midframe** On (3a) Pro, the midframe and buttons are produced using 100% recycled aluminium, a more premium material that is equally elegant and durable. As with our (2a) Series, (3a) devices have antennas embedded around the midframe to ensure great reception. In addition, (3a) Series features an additional high-performance gaming antenna in the middle of the frame. This means that when holding horizontally for gaming, the signal won't be blocked by your hands, ensuring stable and smooth gaming network connectivity. Compared to the (2a) Plus this improvement can reduce lag by over 50% when using a mobile network. The big rectangular space in the middle of the midframe is for our 5000mAh battery, with the space above perfectly shaped to house the motherboard. The long, thin space at the bottom is where the daughterboard sits, along with the speaker, optical fingerprint reader and SIM tray. **🟡 Rear Cover** The premium materials found on the midframe continue onto the rear of Phone (3a) Pro where we find a 2.5D rear glass panel, a significant change from the plastics used on our (2a) devices. Integrated at the top is the housing for our triple rear camera system along with the LED flash - let's zoom in a little closer to this part, there's lots to see… ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2025-03-17/1742206524-937220-nothing-phone3a-product-teardown-05-large.jpg "banner") Above, we get a great look at the space inside the camera bump of (3a) Pro. The lenses of each camera are positioned as close together as possible and positioned precisely to ensure a smooth transition between them when you’re zooming in and out. At the very top is a small diffused aperture for the flash LED to fire through. Speaking of cameras, we have some macro shots of the sensors themselves: ‎ **Phone (3a) Pro Camera System** (3a) Pro hosts our best camera system to date, featuring a versatile array of lenses for portraits, macro, long zoom shots and more - it's super versatile. Paired with our new Camera app which enables sharable, Personal Presets and even allows for the use of LUTs via the .Cube format, there's infinite possibilities to explore. Take a look at some of our recent community reviews from [Palmix](https://nothing.community/d/27843-phone-3a-pro-what-no-one-tells-you "Palmix Art"), [Juse](https://nothing.community/d/27910-3a-pro-a-new-dimension-of-photography-for-nothing "Juse") and [Bubi](https://nothing.community/d/28315-phone-3a-pro-review-is-it-worth-upgrading "Bubi") for some example images. ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2025-03-17/1742206524-741210-nothing-phone3a-product-teardown-04-large.jpg "banner") ‎ ‎ 🟡 Primary - 50 MP Samsung, f/1.88, 1/1.56” sensor, 84.5° FOV, OIS & EIS 🔵 Ultra Wide - 8 MP Sony, f/2.2, 1/4" sensor, 120° FOV 🟢 Periscope Zoom - 50MP Sony, f/2.55, 1/1.95” sensor, 33.6° FOV, OIS & EIS 🔴 Front - 50 MP Samsung, f/2.2, 1/2.76" sensor, 81.2° FOV ‎ **Phone (3a) Pro Periscope:** (3a) Pro features a flagship periscope zoom, a first for any Nothing smartphone. A prism, paired with a horizontally stacked lens assembly, is able to offer 3x optical zoom and up to 60x ultra zoom. In the above image, you can see how much larger this component is compared to a regular camera module - our teams worked hard to implement these segment-leading zoom capabilities with the least possible impact on overall device thickness. ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2025-03-17/1742206525-224505-nothing-phone3a-product-teardown-06-large.jpg "banner") 🔴 Prism - reflects light towards the lens assembly and shifts to deliver OIS 🟡 Stacked assembly of 4 lens elements - directs light to the sensor and shifts to attain focus 🔵 Sony LYTIA 600 sensor - turns light into a digital signal which informs the image ‎ ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2025-03-17/1742206912-939407-teardownbts.jpg "banner") *BTS image showing the periscope alongside (3a) Pro's camera system housing* **‎ (3a) Series Chipset** We heard our customers asking us to bring a Snapdragon chip to our midrange lineup, so for (3a) Series, we used the 7s Gen 3. A powerful chip that can handle gaming or multitasking with up to 33% faster CPU and 11% graphics improvement compared to (2a). It’s also more efficient, meaning there’s an overall improvement in battery life. ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2025-03-17/1742206524-548020-nothing-phone3a-product-teardown-03-large.jpg "banner") We’ve cropped in to the motherboard in the image above, as a bonus, you can see the proximity and ambient light sensors at the very top, helping to illustrate where these chips sit within the device. Shoutout to our photographer David Wilman for removing all of the thermal material so we can get a good look at these components in all their glory! 🔴 Snapdragon 7s Gen 3 5G (SD7635) - Up to 2.5 Ghz built on TSMC’s 4nm process. * 8-cores: 1x 2.5GHz (Cortex-A720), 3x 2.4GHz (Cortex-A720), 4x 1.8GHz (Cortex-A520) * GPU: Adreno 810 * NPU: HTP2 🔵 UFS2.2- Storage + LPDDR4X RAM - learn more about this [in a recent post](https://nothing.community/d/29023-why-we-chose-ufs-22 "UFS 2.2") by @"Raymond"#2947 ‎ ‎**The underside of the Glyph Interface** And finally, the eagle-eyed fans will have spotted that (3a) Series has had a Glyph update, with an adjusted arrangement, all 3 of the Glyph segments are now addressable, with a total of 36 zones. Below we look at the rear of the top left Glyph (Internal notation: Glyph ‘C’), used for our Glyph Progress feature - counting the dots you’ll find 20 addressable segments for a smooth progress animation. ![](https://s3-nothing-prod.s3.eu-central-1.amazonaws.com/2025-03-17/1742206525-387294-nothing-phone3a-product-teardown-07-large.jpg "banner") We hope you enjoyed diving into Nothing Phone (3a) Pro’s fresh look and internals with us - as always I had a lot of fun peeking inside our latest product to bring a fresh perspective to you all! > EDIT: Giveaway now closed.

I like periscope and design of the back camera.

xereor_18

Rob ⚡️ I absolutely love the shape of the camera and I love that it is “diegetic” with the shape of the Glyphs, as if every detail of the back accompanies another detail, it’s all homogeneous and pleasant.

VIDHYASAGARMS

My favourite part is list 👇

Rob ⚡️ One of my favorite things of Nothing phones is the level of details in the components. I still once in a while stare at my phone (1) , you just never get tired of it

Rob ⚡️ I’m in love with the camera.. the periscope and the clearness in zoom is just amazing and also the snapdragon chipset gives an additional boost to this phone.. I wish if I could get this beauty.. 🫠

contra 🇳🇿

Rob ⚡️ I’m most excited for the periscope camera for photos at gigs, and being able to use LUTs as filters. The esim is also going to be nice for travelling!

SyedNabi

Rob ⚡️ I love the 50MP (Main) + 50MP (3X Periscope) + 8MP (Ultra-Wide) camera setup on the Nothing Phone 3a Pro, offering pro-level zoom, clarity, and low-light performance. ♥️ Nothing 🔥

Baldertech

i really like the periscope camera system, looks super cool and is one of the cheapest phones i’ve seen with this camera system

paniagua_jordano

The new periscome lens and the new OIS of the camera.

DiveshNair

Rob ⚡️ The pro periscope is my fave feature! Really cool

joseph_caviglia

Of course the camera🔥

ernestoalonso_

Can’t find my comment, so here it goes again just in case lol

You gotta love Nothing’s level of details. I still once in a while stare at my NP (!) back, I just never got tired of it and they keep getting better with each generation

PranavAlashi

If they had added some more glyph in the back panel, it could have increased the “centre of attraction” thing, but perhaps the cost could have increased..

Juanfu224

Rob ⚡️ me encantan los detalles metálico de la parte de atrás del np 3a pro

WispEnjoyer

I dont think any part of the phone alone is super impressive but the phone as a overall package is very attractive.
Nobody will look at it and think “woah that SoC is amazing” but thats really not what its about.
The 3x Mechanical Zoom is the best feature hands down, it might not make the camera itself better BUT the moment you zoom in to take a picture from a item far away you will notice a major improvement.

Coldpaw

Rob ⚡️ While maybe not a feature per se, but I absolutely love the new camera design. I guess it was a bold move by the design team and I even have to admit I hated it at first when some initial images got leaked, however after seeing the complete product and actual pictures of it, I was instantly hooked.

Kudos to the Nothing design team, well done as usual! 👏

VinayThakur_uWgnJHi4tw

Rob ⚡️ that periscope i love it. I have seen Jerry open that periscope and for the price it’s just a masterpiece.

MarvinChurch

Rob ⚡️ obviously the glyph lights gotta be my favorite

DavideQuaglia

The periscope camera really makes a difference, and having a zoom of this quality in a budget phone is huge.
