Before the MWC 2019, Samsung officially launched the Galaxy Tab S5e, but it looks like the non “e” version will be the Galaxy Tab S6.
The tablet is said to feature a 10.5-inch display and will be powered by the Qualcomm Snapdragon 855 processor. It also will offers 128GB and 256GB storage options and features a magnetic back-up charger, and the S-Pen stylus can have similar Bluetooth capabilities to that of the Samsung Galaxy Note 9.
The images you see above suggest dual rear camera configurations, WiFi and LTE models, and color options Gray, Blue and Brown.
Regarding an official launch, this may occur in the ‘Unpacked’ event of Note 10 on August 7, or later on IFA 2019.
