Unfortunately there is still no word on what the problem might be, but in a statement that Google has since released to multiple outlets, including BGR, it seems that this is not a widespread problem. They also mention that they are looking into the issue to see what is wrong and to determine what kind of fixes might be necessary.
According to the report, “We have teams who constantly manage and monitor performance on our devices and our data indicates this is not a widespread issue. Getting bug reports is a normal part of our process – as is common for most consumer devices. We use these to evaluate what might be wrong and work on any necessary fixes. We are still in the process of investigating this report so it is too early to draw conclusions.”
In the previous report it was also suggested that hardware replacements might be necessary, but here’s hoping that a software update will do the trick. In the meantime if you are one of those affected by this sluggish perrformance issue, we’ll be keeping an eye out for more updates on the problem.
