I love Flesky keyboard. Loved it on my Galaxy S5. On my iPhone 6 Plus, not so much. I only have 2 keyboards enabled. Flesky and a GIF keyboard. Sometimes Flesky will crash and bring up the stock Apple keyboard which I do not have enables. This happens quite often. A few times an hour. It's annoying. Hopefully Flesky or Apple (whoever is at fault for this bug) fixes this soon.
