tab4 and tab pro definitely different sizes
Hi - very useful information that the tab4 Logitech case doesn't fit (and tab3 is also similar, closer in fact, with a Logitech case also available for it). Note that gsmarena clearly defines slightly different sizes in one dimension in particular, but not by much:
tab4: 243.4 x 176.4 x 8 mm (9.58 x 6.94 x 0.31 in)
tabpro: 243.1 x 171.4 x 7.3 mm (9.57 x 6.75 x 0.29 in)
tab3: 243.1 x 176.1 x 8 mm (9.57 x 6.93 x 0.31 in)
I can't help wondering if there's a way to bridge the gap, but 0.5 cm width difference wouldn't be easy I guess - doesn't sound like anyone tried?
