Well all I can say is that it is an issue with everyones phone that we ALL hope will be corrected with the upcoming update.
Can I nicely recommend that you search for some information on some of these issues your having BEFORE starting new threads... The easiest way is to go into "search", a drop down menu of sorts will appear. Type in what you want to search for and search posts instead of threads. I find the most info searching the posts. Everything you are asking has been discussed over and over and should be easily found in a search. When that fails, then by all means, start a thread! Welcome to the forum BTW and I hope you grow to love your Eris
