I had a Sony flip phone since many years with satisfaction. Its battery became bad and I couldn't find any battery replacement.
I bought this Samsung M400 phone because I wanted a "non-smart" flip phone.

- Good reception,
- Good battery,
- Speaker is OK,

- Voice Command button on the left side is bothering and there is no way to deactivate it.
- Voice recognition is really bad. It is practically not usable.
- Display font size is not changeable.
- There is no place for SD card or other memory cards. You can not increase the memory.
- There is no driver for USB connection. You can't transfer photos to your computer, except you send it via email.

I wouldn't recommend this phone to anybody.

My husband and I both got this phone as our upgrade recently. We use our phones only for talking, and need only the most basic features.

Within two months, his phone stopped holding a charge. Unless it was actually on the charger it would not power up. He had to get a new battery from Sprint, and within a week of getting it, started having the same problem again.

My own phone began doing the same thing within days of activation. A trip back to the store resulted in upgrading my settings, but did not solve the problem. As of today we are still without working phones and are about to make our third trip to Sprint.

I'm tempted to believe that phone manufacturers are so busy cranking out smartphones that do everything but wipe your butt for you and cost a fortune, nobody can be bothered to make a reliable, basic phone with quality hardware. Very frustrated and do not recommend this model.

Basic flip phone, but has extremely annoying dedicated 911 button. I can dial 9-1-1, I don't need or want one button solution that can be pressed by accident. I can not fathom why they do not have the ability to disable it.

Kinda pricey for basic phone too. As another reviewer noted, why can't they just sell a reliable basic phone?

This is my fifth or sixth Sprint phone, and it will be my last. In addition to consistently lousy Sprint service, contending with this phone's various drawbacks only adds insult to injury. The voice quality is so poor I often have to switch to a land line. And the battery runs down virtually overnight. Rated for four hours talk time, I'd be surprised to get one hour. Voice mails are logged at a time six hours off. And the keypad often fails to register.

I've taken the phone to Sprint to have the battery checked, but they tell me it's just fine. But Sprint will not attempt to repair the phone; rather, they offered to send it back to Samsung for a $50 fee.

Don't buy this phone. Keep looking.
