Hardware Impressions: Run of the Mill Motorola, aka Good Build Quality

The last Motorola phone I owned was the v70. Brian handled all of the 2nd generation Droid reviews, and while I've used them I never did so for an appreciable period of time. From the StarTAC to the v70, I will say I had some good experiences with Motorola hardware.

The Atrix 4G is no different. The phone is pretty light at 135 grams, that puts it in the class of the iPhone 4 and Optimus 2X (although the Atrix is lighter than both). Despite its weight, the Atrix 4G doesn't feel cheap - it just feels like a solid block of plastic. There's no discernible flex in the chassis, at least from my experience with the phone thus far. All gaps in the housing are both tiny and uniform. It's a well built product.

On the front is the 4.0" qHD PenTile LCD screen (960 x 540 resolution). At the top of the display is the front facing VGA camera, proximity sensors and notification LED. The LED is green when the Atrix 4G is plugged in and fully charged, it turns red when you are running low on battery and blinks green for all notification events.

Along the bottom of the screen are the four Android buttons, all capacitive. The ordering is identical to the Droid X and LG Optimus 2X with the contextual menu coming first, followed by home, back and search in that order.

Along the right edge of the phone is easily one of the best feeling volume rockers I've ever used. The rocker itself is plastic but with very little play, it feels solid and stationary. Each click, up and down, is perfectly distinct. It's a good quality feeling button.

This is a Tegra 2 phone and thus the left edge has both a microUSB port for charging and a micro HDMI type D port for video output. The two ports are similarly sized and placed close enough together that I always worry about jamming a USB cable into the micro HDMI port. Don't you hate when that happens? Like the LG Optimus 2X, Motorola bundles a ~6 foot micro HDMI to HDMI type A cable with the phone.

The power/lock button is in a unique location on the Atrix 4G. It's angled between the top and rear planes of the phone.

The button's location is unusual at first but I must say it's pretty easy to get used to and after a few days I didn't have any complaints about it. It's not as easy to fumble around with in your pocket than a conventional top mounted switch, but it works and it keeps the outer rim of the phone pretty clean.

The phone's 1/8" jack is located up top. There's a small slit for the primary microphone on the face of the phone. The speakerphone and noise canceling mic input are both located around the back.

The back cover is a thin piece of plastic with a carbon fiber-like pattern printed on it. It's a pretty classy design and the back cover, like the rest of the phone, doesn't feel cheap.

Motorola integrates a 5MP rear facing camera with LED flash on the back of the phone. The camera doesn't protrude beyond the back cover, instead it's recessed by a approximately 1mm.

A side effect of Motorola's tightly assembled design is that there's no notch to jam your fingernail in to easily remove the back cover. You have to instead do a bit of prying at the bottom before you can get enough room to really pull the thing off.

There are snaps located on both sides of the back cover, the top and the bottom just cup around the phone chassis to hold itself in place.

Inside the Atrix 4G is a very large ~7.0Whr battery. Motorola rates it between 1880mAh and 1930mAh. This is actually the first time I've seen a variable rating printed on a smartphone battery.

Like the Optimus 2X, the Atrix 4G's microSD slot is accessible without removing the battery. You do need to take out the battery to get to the SIM slot however. The Atrix 4G ships with 16GB of on-board NAND, so the microSD slot remains unpopulated by default. Of that 16GB only 14GB is available to Android (and of that ~11GB is for media storage). The remaining 2GB is presumably used for Motorola's webtop Linux environment. I managed to copy to the Atrix 4G's internal NAND at a peak of 10.5MB/s over USB.

I should mention that the name Atrix 4G refers to the fact that the phone supports HSPA+, not because it is an LTE device. I've only done a limited amount of network performance testing but so far I've peaked at 3.1Mbps down and 938Kbps up. Average performance in Raleigh, NC seems to be in the 1 - 3Mbps range downstream. My upstream performance has been limited to a UMTS-like 300Kbps, however I need more time to figure out why I'm not getting consistently higher upload speeds on the Atrix.

    i spy with my little eyes a 780i motherboard.

    Nice writeup! Can you send a SMS from the portal? Or just view/delete? Would be convenient to be able to chat over SMS without having to get the phone out of my pocket

    Hi Anand

    Just noticed that you mentioned two different resolutions;
    In the text: "On the front is the 4.0" qHD PenTile LCD screen (960 x 540 resolution)"
    In the table:4" IPS-LCD 800x480

    Can you please confirm/fix? I hope the first one is correct!


  • Chloiber - Sunday, February 13, 2011 - link

    There is a whole page about the screen...
  • CallumS - Sunday, February 13, 2011 - link

    Yeah sorry I noticed that later. Obviously just the table is wrong.

    Looking forward to this and other mobile's with high resolution displays!

    It does seem to make sense to move phones towards the desktop. They are, or will soon be, powerful enough for most uses. However

    - the price is outrageous. I can get a very good netbook or even laptop for less money
    - the whole setup is proprietary. With the accelerated mobile phone upgrade cycle, it means it's money down a very fast drain. A netbook/laptop will be easier to re-use.

    HP's tap to synch approach makes a lot more sense until these two issues are solved, if they ever are.

    Thanks for this great preview, this phone seems to be a really great device :)
    One question though, do you know if the LED is multi color ? You can test this with Blink (you have to switch off screen after choosing a color). It's on the market : https://market.android.com/details?id=imoblife.bli...

    My carrier has no influence on what phone or what software is on that phone at all. I never buy my phone through my carrier, always just on 1 of the many gsm webshops there are over here.

    Most of the time i just buy my phone when ever a phone comes around that i want to have, i don't look at my contract at all (i also could do that but i most of the time don't do that)

    So buy my phone for 600 euro.. then i go to my carrier when my contract ends (when ever that is) and then i ask them what the best sim only contract there is what they can offer me.. (1 or 2 years). Currently the 2 year was the best so what i get was a 25 euro contract per month where i get 40% off over 2 years, and the first 6 months i did get an additional 50% off on top over that.
    So that's the first 6 months 17.5 euro off (105 euro) and then 18 months 10 euro off (180) thats in total 285 euro that i save, so that i only payed for my high end phone 315 euro on a contract of 25 euro.. And i can buy whenever i want a new phone and extend my contract when thats around the corner.. they are not related to each other.

    They apparently want $500 for the laptop dock and $130 for the desktop dock, not to mention tethering charges WHEN YOU ARE NOT TETHERING.

    It's completely absurd, and is probably the first time I've actually started wishing for carrier subsidies to be outlawed, as they are in some countries.
  • svengalis - Sunday, February 13, 2011 - link

    Nope it can't mirror. This is why the Optimus 2x is better to me. It does TRUE mirroring of the WHOLE UI so no need for this silly laptop dock when I can buy a cheap laptop and do basically the same thing for FREE.
