I apologize if this has been asked or answered before but I don't know the proper way of wording it in search. I just recently bought a Samsung Mesmerize Galaxy S for U.S. Cellular which is currently running 2.3.4 firmware, kernal 220.127.116.11, and build sch-i500.EH09. I am having a ton of issues with this device freezing, locking up, and just running slow. I have seen there is lagfixes out there but not sure what I can use and how to do it to help speed up this phone and correct the issue. I like the phone and don't want to return it so if anyone can help point me in the right direction and walk me through applying a fix I would be grateful. Thanks.
