Analysts believe a lack of available touchscreens could be responsible for delaying the UK launch of Apple's iPad.
"That they have been doing it for the iPhone for some time is great, but once you go to 9.7in, it is a much more complicated process."
Both Apple and Samsung declined to comment, while LG and Seiko didn't respond to requests for comment Bloomberg said.
Apple's iPad won't be available until an unspecified date next month in the UK, Canada, Australia, France, Germany, Italy, Japan, Spain and Switzerland.
Apple will however, announce international pricing details on Monday 10 May.
