FiiO are saying there is a problem regarding WiFi with the Exynos 7270 chip. Yet many of us do not seem to have a problem with the WiFi cutting out. Is this happening when the M9 'sleeps', because mine has never cut out. It seems to be that some do drop WiFi, but it must be a Samsung quality control problem as many don't drop WiFi yet some do. FiiO do have responsibility though as they are manufacturing and selling defective products. Each country will have different sales laws. In the UK the laws are quite good. For those that bought through Amazon, returning products is easy enough. If bought through the FiiO shop, or other sellers, how responsible will they be?
