Default Caution!!! 4.4.3 Bugs Spoted...

We are very excited about 4.4.3 update in the air rolling, but i found in Motorola forum, after updating in 4.4.3 user experiencing a major problem of dropping signal in WiFi rapidly. GPS satellite tracking is very slow around 10 min. of spotting satellite & sometimes battery draining quickly than before. So anyone knows any known bugs about 4.4.3, please share....
