What People Are Saying

Rated 5 out of 5 by from Great phone Easy to use. Easy set-up. Transfer from old phe is a snap

Rated 1 out of 5 by from Horrible Boost sent me this phone as my Samsung in being repaired and still under warranty. They claim this is a huge perk to have a loaner phone. The phone arrived 2 days after my Samsung quit working. It is awful. Tiny screen, small, keypad and I can't put ANY apps on it as it has hardly any memory. In addition, my contacts didn't transfer because the phone can't handle hardly any memory. The phone retails for $20-30 and this is their way for treating a loyal customer for 4 years. I asked why they don't have refurbished phones (ones of nicer quality) at their Boost stores that you could "rent" while your phone is being fixed, instead of a 2-3 day wait time and then sending you a phone that you cannot even fully use. The agreed to credit my account $10 for the hassle. Wow! $10 is extremely generous. Not to mention it took me 4 hours and 5 representatives to try and solve the problem of this phone not working. We run our business line through Boost and now we are planning to switch. You also cannot submit this review unless you agree to be part of their email list. Nuts!

Rated 2 out of 5 by from I got this phone as a last resort. That's exactly what it should be. Storage is awful; LG has limited the SD card capabilities to only allow file transfers.

Rated 1 out of 5 by from This phone sux I got his phone while another phone with cracked screen is in repair shop the 8gb internal mem on phone is full of completely useless apps i will never use and you cant delete them. I have only one app i added only one and memory is completely full then it wont send or recieve text because it pops up memory too full to send recieve messages. I also added a 32 gb memory card but nothing can be moved there besides photos. I cant add anything i want on this phone only whats there oh and because mem is full it cant update the useless apps or phone either. I gave this one star it doesnt deserve that. I have had 3 weeks. Be glad to get my old phone back and trash this in dumpster.

Rated 2 out of 5 by from Problems with storage I understand that this may never a Android update, but at least add more storage to the hardware

Rated 5 out of 5 by from Good phone I dont know what the other reviews are complaining about. I have none of those probs. Its simple and easy to use. Very fast response. Lightweight. Works with my kindle fire charger so that's a bonus

Rated 3 out of 5 by from ok phone for the price Have had it for a month now, and when I first got it and turned it on it was very annoying with it voice commands. It has far to many apps loaded on it that I will never use, or are useless to most people. Put on the basics and let US add what WE want. The battery dies way to fast and I hardly use it. I clean it up often, but that doesnt seem to help. Screen touch is good, but a screen saver seems to have effected this. I am still learning things with this phone, and wish I could get the Google search box off my home screen and get it to go to a 2nd screen I can swipe to. I also dont care for the keyboards, neither of them has a true back button like my actual keyboard on my old phone, but I am dealing with it. It just very annoying to take extra steps just to back space w/o deleting. So its a decent phone for beginners or those who cant afford something more.
