There is no problem running the SPARK in high temperatures. Although i feel the latest SPARK production quality are not the same quality as the Mid June 2017 production models.
Although it tells me the high temperature still works perfectly. I only get these messages with the current application of the playstore. With older versions I have no problems with the notices.
Our apologies for the inconvenience. Does the error message disappears after a couple of seconds? Kindly check if you can hear the internal fan working. If yes, please do not feel worry about it. Any problem, please contact us again.
