Samsung SPH-Z400 User Reviews

This phone is horrible. battery will not make a full day, it locks up in some kind of sleep mode or something niether receiving nor making calls or texts. it looks like it's working fine and will do everything but actually connect or get a call. have to cycle power constantly via batery removal to get out of sleep mode. ive turned off  all un needed buttons and lights but in my pocket the side buttons are pushed causing light to come on...etc etc...bye bye battey life. buy a couple tin cans and a roll of string for better service.

Don't waste your money on this phone. Horrible PTT phone. Audio quality is terrible as is placement of buttons.

Got the Sanyo PRO700 which is much better.
