Xperia android 4.2.2 bugs: slow web browsing and strange battery metering

[dynax73]

With latest sw version 4.2.2 i found two problems. Web browsing via wi-fi seems to be slow, really slow loading of web sites. Also the battery management has bugs. This is the screenshots. Note that I haven't recharged the tablet in the 9 hours analyzed (i have just turn off and turn on the tablet).

I have not noticed slow WiFi or battery drain.

it seems like a system reset. maybe your xtz reboots operating system random few Times a day?

i suggest to reflash your device by sony update service. remember to backup your personal data
