LG840G: a solid semi-smartphone from Tracfone Wireless

Looking for a solid, inexpensive phone, but don't want to deal with those pesky contracts? Tracfone has you covered.

Although the LG840G is far from being a new device, it's the latest in Tracfone's efforts to modernize their phone selection. A bit of a cross between a standard feature phone and a (very) low-end smart phone, the 840G packs some interesting features that puts it above all others in Tracfone's lineup. Like one YouTube reviewer put it, "this phone is the leading edge of the trailing edge of cell phone technology."

Costing just under $20 USD reconditioned (or up to $60 USD new), the 840G features a 3.2-inch compacitive touchscreen, 3G/wi-fi connectivity, Bluetooth capability, a 2 GB micro-SD card, and triple minutes for life.

Update: at the time of this writing, the 840G was the best Tracfone had to offer. Very recently, they made available two full-fledged Android smartphones, the ZTE Valet ($99.99 USD) and the Samsung Galaxy Centura ($129.99 USD). Other newly-released smartphones, such as the LG Optimus, are only available through select online retailers such as QVC or HSN. I was wondering when Tracfone would start releasing 'real' phones -- I guess I have my answer...

Appearance & Build Quality
The 840G is definitely one of the more solid Tracfones I've used. It's somewhat heavier than the 800G, but only slightly larger in dimensions. In contrast to the 800G's rounded corners (which make the phone fit nicely in the hand), the 840G is much more rectangular with 'sharp' edges. The battery cover is made of a cheaper plastic and snaps (rather than slides) into place. Even so, after being locked into place, it doesn't at all feel flimsy and can't easily pop off.

There are only two physical buttons, the volume rocker switch (left side), and the power/lock button (top). A standard 3.5 mm headphone jack is also on the top of the phone, with the charging port on the bottom. The 840G really does look and feel like a small smartphone, and could easily pass for one at a distance.

The Screen
The compacitive touchscreen is light-years ahead of the resistive display on the 800G. It's much more responsive and can be used with a light touch. Considering the screen's low resolution, the display is bright, clear, and easy to read. The overall larger display allows for much easier use of the on-screen QWERTY keyboard, although people with big fingers may still have trouble.

The Camera
The 840G's camera is a fairly standard low-end camera phone, maxing out at 2 megapixels. It's not a great 2 megapixels at that, but it works fine as a backup or I-don't-have-a-real-camera camera. It doesn't appear to be as sensitive to movement as the 800G's camera is -- the 800G camera would constantly blur with the slightest movement. I've yet to test the phone's video capability.

Internet Connectivity
The 840G is the first Tracfone to come equipped with both 3G and wi-fi internet. This puts the 840G into the realm of 'semi-smartphone'. Is it a good web-surfing platform? Not really, but for the basics, it works fine.

Wi-fi access is totally free, but surfing at 3G speeds will quickly eat up your airtime. The included web browser is pretty basic and doesn't handle complex sites very well. This can be remedied by installing Opera Mini, a portable version of the Opera desktop web browser.

The phone also comes with an email client, but I haven't had any luck getting it to work properly. On the other hand, the generic social networking app seems to work fine for Facebook, and even allows for photo uploads. If that's not enough, the phone supports most Java-based apps.

Battery Life
Under light use, the phone will last about a a week before the battery dies. Beware that if wi-fi is turned on, the battery will drain in half that time. Also keep in mind that when the battery is low, the phone doesn't give much warning, so charging proactively is probably a good idea.

Operating System
Althouth the 840G looks like an Android smartphone, it runs a stock LG phone operating system, featuring three home screens (contacts, widgets, & app shortcuts) and an app tray. It's very similar to the one on the 800G, but with some marked improvements. Overall, the OS is very easy to navigate, especially for former 800G users. Even Android users will (more-or-less) feel right at home. Needless to say, it's not nearly as flashy as Android or iOS, but it's solid and functional.

If you're looking for a cheap phone that does all the basics plus a few extras, check out the LG840G. It may not be cutting edge, but it's more than sufficient for any Tracfone user.

Tech Tutorial: Installing Opera Mini on the LG840G

Opera Mini is a portable version of the Opera desktop web browser designed to run on mobile devices. In this tech tutorial, we're going to spruce up the LG840G Tracfone (full review to follow) with a browser upgrade, making the phone's 3G/wi-fi connectivity a bit more practical to use. We'll also disable the annoying Java keypad, which, by default, takes up half the screen and just gets in the way.

Keep in mind that even with this upgrade, browsing on the 840G is far from ideal. It works well for what it is, but isn't a replacement for a tablet or other 'true' mobile device. Opera runs fine, but does lag a bit.

I've found that the easiest way to get Opera up and running is to download it on a desktop PC, edit the config file to disable the keypad, and then transfer the file to your phone.

Part 1: Download & Modify the Opera Mini installer
  • On a desktop PC, go to the Opera website and download the latest version of the browser (at the time of this writing, version 7.1). The installer will be a .jar file archive/executable.
  • Now it's time to disable the Java keypad. Open the archive using your favorite zip file extractor, such as 7-Zip. Assuming you're using 7-Zip, right click > 7-Zip > Open Archive.
  • Locate the META-INF folder and double click on it. Within the folder, right click on the file META-MF > Edit. The META-MF file will open in your default text editor, such as Notepad.
  • Copy and paste the following below the existing lines of code:
    • Nokia-MIDlet-No-Exit: true
      Nokia-MIDlet-On-Screen-Keypad: no
      Navi-Key-Hidden: true
      UseNativeTextButtons: hide
      ReverseSoftkeys: hide
      UseNativeCommands: hide
      MIDlet-Touch-Support: true
      MIDlet-ScreenMode: ROTATE
      MIDlet-Landscape-Support: true
      LGE-MIDlet-Width: 240
      LGE-MIDlet-Height: 400
      LGE-MIDlet-On-Screen-Keypad: no
      LGE-MIDlet-Display-Mode: both
  • Click File > Save and then close the window.
  • 7-Zip will ask if you wish to modify the archive with your changes. Click 'Yes' and close the 7-Zip window.

Part 2: Install Opera Mini on the 840G
  • Connect the 840G to your computer using a standard micro-USB data cable (keep in mind that a micro-SD card must be installed to do this). 
  • The phone will ask you if you wand to 'connect as mass storage'. Tap 'OK'. The phone will now display 'Connected as Mass Storage Mode'.
  • On your PC, locate your phone under 'Computer' or  'My Computer' -- it will show up as a removable storage device.
  • Copy the modified Opera Mini installer to your phone's memory. Note it does not have to be placed in any of the existing folders.
  • On the phone, tap 'Exit' and then disconnect the cable. The phone will display 'waiting' until cable is unplugged.
  • Open the 840G's File Manager (found on the second page of the apps tray) and locate the Opera installer under the memory card tab. Tap to launch.
  • The phone will display 'Untrusted Midlet'. Tap 'Continue'.
  • At the next screen (displaying information about Opera Mini), click 'Download' to begin the installation.
  • Opera Mini will then install, which should only take a few seconds. At the 'Download Completed' window, tap 'Launch Now' (if your wireless is not enabled, the phone will automatically connect via 3G and use airtime).
  • Opera Mini, sans the Java keypad, can now be found under 'Games & Apps'. For quick access, add 'Games & Apps' to your shortcuts home screen (unfortunately, there doesn't seem to be a way to make a dedicated shortcut).

With a few other adjustments (such as setting the browser to both landscape and fullscreen modes), Opera Mini works well on the 840G for basic web access. I mainly use it to check email since the phone's built-in client doesn't seem to work. My only real complaint is the on-screen keyboard has very small buttons, making typing anything quite tedious. My suggestion: take advantage of bookmarks.

Interested in installing other Java-based apps? It's as simple as downloading the file on your PC and copying it to the phone's memory (or downloading the app on the phone itself). Then, simply launch the installer. Any installed apps will appear under 'Games & Apps'.

I hope you've found this quick tutorial useful in getting Opera Mini setup on your LG840G Tracfone. Happy web browsing!
