Samsung is set to unveil its next Galaxy phone on August 23. Some serious pressure is surrounding the Samsung event after the last Note phone, the Galaxy Note 7, shipped with faulty batteries that caused explosions and led to two separate product recalls. Since then Samsung has vowed better batteries and recommitted to the Note brand. 

With the grand announcement coming on August 23, Note 8 preorders may start as soon as the next day.
