Games freeze

I have the android tablet ‘Hudl’ which uses the jellybean 4.2.2. And I have a problem with the game freezing sometimes on loading screens but after a minute or two it unfreeze and I can play once in game. The main problem though is when I try to upload my account or download. Each takes about 10 minutes as it seems to start uploading then freeze then start again then freeze until it finally uploads after quite some time. Downloading takes even longer. I never had this problem before the most recent update. I used to be able to upload and download fine. Then I was unable to do either for awhile whilst the account problems were in place. Then after the patch it’s just really slow and I get freezes.

I have tried reinstalling the game etc. but seems to have no effect. I also tried being signed in and out of game circle but the makes no change.
