Thanks for your feedback, but as i stated in my previous post, i need this issue to be confirmed also from other users. As soon as i get it, such issue will be forwarded to the tech team.

It has been confirmed for other phones... You expect that someone else with a BV5800 will confirm this? Check the number of posts and visits on this sub-forum, there's almost no one here compared to BV9500 or BV6000 subforums. If you expect someone else with a BV5800 to confirm this, you might as well tell me that it won't ever be looked at.

If you estimate that it's not worth troubleshooting for a single user of a BV5800 Pro, then please write as such, this way:

• I will stop wasting my time trying to raise issues and trying to troubleshoot. Do you have any ideas how many hours I wasted on this?
• I will report this thread to the seller, and ask for a refund, since Blackview will not assist in troubleshooting, despite having followed all procedures and having the phone replaced under warranty.

OK, will forward such issue to the tech team.

Confirmed!

Whenever a peripheral issues a Connection Parameter Update Request (in Bluetooth LE mode), the BV5800 pretends to accept the request but then goes wild and terminates the connection.

Such issue has been already tracked, a fix will be released together with future updates.
