after using .161 from .124 my device was very slow until i pulled the battery twice, then the device load fine and the speed on opening and closing apps seem faster. resending the service books from my phone changed abit but nothing to worry about. over all seem like the device runs faster. side note is the radios turned off on my device and could not turn them back on until I let my device charge to 10% but wifi still worked so no interruption on my service.
