BLU Tank Flip T0100U | 2.8" Display| 2022| GSM Unlocked | 4G LTE Flip Phone (Green)

This is a bad phone, even for a basic phone. First, the call experience is poor, people on the other side always complain about the audio cutting in and out, though if you turn on the speakerphone, then it works. But what if I would rather not be on the speakerphone? Secondly, the phone doesn't allow you to talk on the phone using bluetooth earphones unless you keep the phone open the entire time. Third, the brightness control is just totally broken. When you change it, the brightness randomly goes up and down.

Phone not unlocked!
