Personally, I think samsung should reserve Exynos for A series and FE series smartphones and tablets until samsung manages to improve the situation. The Exynos 2400 was better than Exynos 2200 so there's hope.
Yeah they probably should. Problem is there is a lead time on many tech products of years. Even with iterative tech like phones it's likely to be 18 months to 3 years. So Samsung will have limited options in terms of modifying it's roster of upcoming devices. Devices may be ready to go into production in factories already, awaiting the chips. Chips may already be going into the "wrong" devices and it may take them time to focus onto their premiere products. And they likely won't have alternative designs to go for other products without the Exynos chips so no matter what they do this could be damaging for them if this is true.
But it all really depends on how "low" the chip yield is which nether article can quantify.
