Android 7 Bluetooth disconnect and connect

todakom

I tried to let my handsfree disconnect and connect to see what happens. After about 1 hour disconnecting it ending in approximately 2 hours but now its the same again. I've tried with both headphones and my stereo, it's the same.

I also noticed that the issue is very intermittent. I connect to the car radio via bluetooth for my 90-minute (each way) commute. At first I thought it might be the car radio receiver, but yesterday this issue repeated itself many, many times. This evening it only did it once. Seems very unpredictable. I tried turning off battery optimisation for any apps to do with Bluetooth, but it's not helped in any way.

In another tread I vented a bit over the huge battery drain of BT. Tried the suggestion kindly given by Makaveli ( http://community.umidigi.com/forum.php?mod=redirect&goto=findpost&ptid=6369&pid=39480&fromuid=250090 ) - And if nothing else,I've experienced zero disconnection issues since I followed his advice.

Well, the spontaneous disconnect is better, even if I have "trouble" (read: it doesn't work at all) with automatic reconnect when my watch and phone has lost connection due to being separated (I have to toggle BT off and on again before I can connect again). Battery drain is way better - 25% now, rather than 75-80 last charge.

Okay now I labbat and played with android 7 in one of two of my umi super (Android 6 in the other), and these are my experiences so far.

1: Rapid charging operates approximately every third time after factory reset, but a little slower than with android 6. (Takes about 20-30 minutes longer with android 7)

2: The battery lasts about 2.5 to 3 days without bluetooth and about 14 to 18 hours with.

3: Bluetooth disconnecting and connecting every two minutes. After restarting the phone and turn off all battery saving. then restart the phone again, and then turn on Bluetooth and finally turn on the battery saving again but not for Bluetooth, it works until I turn off Bluetooth or disconnect from what is paired with it.

4: When I install something from the Play Store, I have to restart my phone to see that the app is installed and start it. (Solved the problem by taking out the memory card and do a factory reset and then install the memory card again)

5: Android 7 do not follow in the graphics compared to android 6 (using the same film file and game app installed for comparison) Android 7 takes a little more time to start the film but started app game faster but get little lag in both the film and the app game just beginning.

6: The fingerprint reader works flawlessly.
