"After I got up."
Translation:Ar ôl i mi godi.
No difference. In the colloquial language, i mi and i fi are interchangeable. In the more formal language, i mi (sometimes imi) is usual.
"pay attention to the accents" How to do that in the android app? Any suggestions?
I am not an Android user, so I cannot help directly. If you ask that question on the general discussion board somebody will know the answer - it may be there already, as I am pretty sure that it has come up there before.
One thing to try is just to keep the key pressed down for slightly longer to see if any accented characters come up - that is how it works on iOS devices, although which characters are available can be dependent on language and region settings.
Try long-pressing the vowel key and you should get a pop-up with accented versions of the vowels -- then slide your finger over to the appropriate one (e.g. circumflex in ôl, acute in casáu, diaeresis in polisïau).
I downloaded the 'Swiftkey' keyboard and then got both the Welsh and the German keyboards, so as to get all of the accents needed. This is not without risk of auto correct then randomly inserting both Welsh and German words into normal English conversation, but it does make things more interesting if you forget to check before pressing send.
