What People Are Saying

Rated 3 out of 5 by from I like it except for a few glitches We got our phones a week ago and overall it has everything I need however does anyone else have a problem with stuff just appearing out of the blue. I had set my phone down on the counter and a few minutes the camera turned its-self on. This has happened a couple of times and then this morning I couldn't get it to turn off and had multiple programs popping up. Finally I turned the phone off and back on. It seemed to solve it for now. Also my car bluetooth connects but doesn't stay connected so I have to start it up every time I get in the car. Is this normal? We got this phone because they were out of the one we wanted with no eta on replacements.

Rated 4 out of 5 by from Good phone I had this phone before coffee was spilled on it. I switched to Cricket and got the Harmony again. But this time it does not have fingerprint recognition. Why not when it has the button for it???

Rated 4 out of 5 by from Good inexpensive phoone Have not had any issues, music plays fine, seems as fast as my last phone, added a 32GB sd card holds lots of music and audio books. So far I have not had any problems, love the removable battery

Rated 5 out of 5 by from Easy This smartphone is so far the best phone for a low budget. I would have to recommend it to anybody

Rated 3 out of 5 by from good for the money It works good for the money except that you can not use SD card for internal memory. It has been disabled. My old phone had a nice panarama feature that this phone does not have, but other than that it is ok

Rated 3 out of 5 by from Same glitches as other users After being with Virgin for several years I had a nightmare trying to reestablish service which was disconnected for an unknown reason. I switched to Cricket and overall I am very satisfied. I don't need all the bells and whistles of the latest most expensive phones nor do I want to have a monthly phone bill as big as a house payment. Disappearing keyboard and dead air while playing music is frustrating. For the overall price and quality of voice and text connections, I am satisfied..

Rated 5 out of 5 by from good features My son and my husband have this phone from Cricket and they both like it, I am sooooo glad we changed to Cricket service. The phone was a bargain and replaced their old LG L90 from the PINK carrier.
