Summary: My most recent T-Mobile devices have been an SIII and the LG L9. With the exception of LTE the SIII was superior in every way so this review will focus on the comparing the F3 to the L9. I got mine on here on Amazon for $199 but I've seen the price since come down to $188 on two occasions. The F3 has a slightly lower resolution but the smaller screen makes up for this. The processor is faster at 1.2GHz vs 1.0GHz and is noticeable.
Summary: For a 4G smartphone, this is quite the powerhouse when it comes to lasting. I can unplug the phone in the morning have it run 4G with auto-sync and everything the LG Optimus will have still have 8 hours of battery at the end of the day. After having the phone for about a month, I have found a major drawback - there is only 1.28GB of internal storage. I have yet to find a way to transfer apps to my SD card. This makes me unable to install all the apps I would like.
Summary: I got this phone as a replacement for the LG Optimus Elite which I liked very much but had stopped working after 9 months. The F3 is significantly faster (both internet and system) and it has both rear and forward facing cameras. It's a really nice phone EXCEPT it only has 1 gig of storage (compared the Elite's 8 gigs). Apps cannot be moved to the SD card! I ran out of space in a week and and had begin the process of pairing down apps.
Summary: Most of the reviews on this phone are pretty accurate. The F3 is relatively compact and comfy in hand. The screen resolution is far from the sharpest available but photos and text and images seem especially vibrant on this phone compared to most in the same price range on Virgin. Build quality though, while super plistic-y, seems solidly made.
Summary: Over all it's a good phone, but the add is misleading. It is advertised as 4 gigs of internal memory on website but only 1.27 usable. If you like to download lots of app probably not the phone for you (look at the LG Motion). You can install a app2sd for apps that will allow it. Also, it is very light... you might want a case that has some grip because is easy to loose control and drop. The screen is very nice for the price range. Hope this helps.
Summary: GOOD PHONE FOR SOMEONE THAT USES FOR MOSTLY CALLS.IF YOU DON'T NEED ALL THE BELLS AND WHISTLES THEN THIS IS THE PHONE. WAS NOT TOO PLEASED WITH THE PICTURE QUALITY BEACUSE THAT'S WHAT I MOSTLY USE THE PHONE FOR
Summary: Had this phone for awhile but took it back after it kept randomly rebooting. Never figured out why it did and the people at the return desk didn't offer any explanation. Wanted the phone to work for me, but that was unacceptable. If I could of resolved the issue I would have kept the phone.
