Marshmallow issues

For who read my previous thread about the sudden death of the C5 will be interested to know that to fix various issues I ended up doing a software repair which, of course and sadly, installed marshmallow.

After two subsequential software repairs the device runs pretty well however two issues are not going away and driving me crazy.

Spare the question about safe mode because I did check in safe mode...

Here are the issues: bad wifi and Bluetooth. It disconnect every now and them if there is any Internet or Bluetooth activity.

If wifi dies, Bluetooth is the next to die, if Bluetooth dies same happen to the wifi.

This time is not related to 5ghz and 2.5ghz band, it's a probable buffer overflow becasue the way present itself is a typical bottleneck and then crash of the stacks.

So, I don't know. What's the opinion of the pros? I believe that it's software, not hardware... But you, what do you think?

Re: Marshmallow issues

Latest software update and maintenance update fixed the issue for me.

I need to say thank you to CameronT and Rickard as well to the Xperia Support team in Mexico as they leaded me to find the right solution.

The solution was quite simple. If you received Marshmallow via XC and a software repair doesn't fix several issues, remove the sim card and the SD. Reboot the phone and perform a software reset.

After the software reset proceed with the setup of the device, connect to WiFi and allow it download and install software updates from What's New. One of them will be a maintenance update with no information whatsoever.

Turn off the phone, put back the sim and the SD card. Turn on the phone. Enjoy your C5 fully functional and issues free.

Re: Marshmallow issues

@YoGem,

 

I am confident that you've done all the regular troubleshooting, so I am not sure if there's anything else I can suggest to resolve this. It may be a a pre-existing issue that was exasperated by the update to the drivers and such, could be something else entirely. I think all I can say is, contact your Local support.

Re: Marshmallow issues

CameronT I have news for you, I haven't contacted Sony MX yet but I noticed the following:

The phone run even smoother if there is no sim card, so I won't lie I am not using the C5 as my daily ride however Rickard asked me to capture a log of when the issue happens so what I did is that without Sim I went in my car, connected the C5 to the stereo via Bluetooth, streamed with Spotify while connected to my home WiFi, and Bluetooth also connected to Moto360 and SWR10 - all went fine and smooth, wait... Not only smooth... But even smoother than before!!!

So today at the office, I was having the C5 with me and tried with 6 different Sim cards, no matter what carrier or Sim card the issue occur.

Now that I am home I am going to try again the C5 with Sim card, do again the experiment and collecting the bug report to send it to Rickard!!!

Recap: with Sim card, wifi and Bluetooth generally die, without sim it work perfectly and smoothly.

Re: Marshmallow issues

Update: didn't have the time to do testing as I am using my Z3c and the Robin (I've been a backer on Kickstarter) but I am not giving up about the C5, I'll put the sim card back probably during the weekend and do tests with Bluetooth and WiFi, capture a bug report and send it to Rickard.
