Ive had this phone for about 3 weeks now and I like it alot.
Battery seems very strong and can hold for a long time with open programs like navigation apps and music apps.
Speaker is very loud and actually quite good. Phone mic seems a bit weak since some people say they cannot hear my while talking on the phone, but when I get my mouth close to the bottom of the device it seems to be ok.
One issue that is a bit bothering me is that the phone will not always open immediately after a double tap on the screen, seems like it doesnt respond to every double tap I do.
Overall I am very pleased with the phone and it looks very strong and fast.
