Samsung’s Galaxy S8 and Galaxy S8+ might have only been announced just last week, but the South Korean phone maker is already hard at work on its successor.

Sources have indicated that Samsung has been working on the display panels of the Galaxy S9 since late March, Phone Arena reported citing Korean news outlet The Bell. If what the sources are saying is true, Samsung is already six months ahead of its schedule.

One of the reasons why Samsung is so early into developing the Galaxy S9 is because of its stricter quality control process. This new safety and quality control process was implemented immediately by the company after the disastrous Galaxy Note 7.

The team behind the Galaxy S9’s display panels have set a goal to supply samples by mid-April. The report claims that other key parts of the handset will go into develop about a month after the display panels are supplied.

There was no information provided about the Galaxy S9’s specifications, but it really is to early to speculate on that anyway, as pointed out by Ubergizmo. What’s important right now is that Samsung is preparing for the April 21 release date of the Galaxy S8 and Galaxy S8+ and its plans to bring back the Galaxy Note brand later this year.

The Bell’s report also included some rumors regarding the Galaxy Note 8. The device is said to have the largest screen on any of Samsung’s current lineup of smartphones with a display size of 6.32 inches.

It’s also being speculated that the fingerprint scanner will be embedded beneath the Note 8’s display. That feature was supposed to have been part of the Galaxy S8, but Samsung was unable to make it in time and instead placed the fingerprint scanner on the back of the flagship device just beside the camera to everyone’s discontent.
