This morning I went on business, the battery charge was 92%. I did not use the phone for an hour. Returning home, he took out the phone, and he turned off. I connect the charging - vibro - logo - the icon of the discharged battery, asks to connect the charging. I take the battery from my spouse's phone, everything is fine. I put my battery in her phone - vibro - logo - the icon of the discharged battery, asks to connect the charging. Conclusion: the battery, which lasted 3 years, still holding a charge of 1, 1.5, 2 days up to 20%, suddenly abruptly departed to another world: D. I ordered it on the craftmann website, it's expensive, but I really like the phone. All that I need is still working. I wanted to order Pocofon 1, but changed my mind, from the 640th I will be until the end of her days. I got the 650th from the nightstand, until Thursday I will be on it.

Rep: (1)
I ask for advice.
Which of the w10m builds is the most stable and most similar in speed to 8.1? Now it’s worth 10586 and it seems to be nothing, but not all applications agree to put it



Rep: (70)
I don’t know if this is a bug or a feature. Did a reset, rolled up a backup. It seems that everything works, then for the sake of what the reset did, it was cured. But such strange behavior appeared, with Yandex.Navigator running, all events occur without sound, neither SMS, nor calls, nor messengers do not blink and do not ring. Before the reset, the sound did not behave like that. Where to dig? What to tighten up. It seems everything was covered, and did not find where to turn on the sound back.



Rep: (42)
* SimbaD21,
In my experience, after resetting, I do not raise backups, because it happens that some minor bugs are caught. On the navigator, as an option, check whether the sliders are in the notification settings. Or remove the application, reboot and install again.



Rep: (70)
* Samlp,
Reinstallation did not help. Maybe you need to tighten up the sound routing somewhere? Only where?



Rep: (42)
* SimbaD21,
Parameters - System - Notifications and actions, and see if the sliders are there, if so, scroll down and see in the appendix whether the sliders are in it.



Rep: (70)
* Samlp,
All sliders are in the on position. And notifications usually sound normal. Some kind of crap with the fact that in the foreground an application with sound is not in “Call and notifications”, but “Multimedia and applications”. Calls and notifications are not heard at this moment. Well, if you notice a blinking curtain. It seems that you will have to do a reset and not use a backup.



Rep: (2)
Question: which application will show the location where there is no connection at all?
I tried the standard Maps, Yandex maps-without the Internet does not want to work.
Does not determine my location (in the settings, all the sliders are on)

I tried the standard Maps

And were the cards uploaded to the smart?



Rep: (2)
Yes. In the phone’s memory.



Rep: (144)
Just checked: everything works offline. Recheck the cards.
Although in your case it is very similar, the matter is not in the cards. Leave the phone longer in the open sky. If the almanac has not been updated for a long time (it was online), the GPS chip will calculate the location longer. Of course, if there is no problem with the GPS antenna and hardware

I understand you are on vacation and went somewhere? A month ago, I also encountered this on vacation. The location worked very poorly, showing-not showing without any system. I just used Maps.

Hello, I'm going to install Windows 10. Can there be a problem in the fact that data from the phone can be erased?



Rep: (24)
* Vitaliy_Kopoi,
It depends on how you set it. If there is no problem now with 8.1, then put it right like that, without any dumps. Everything will be saved, even screensavers, calls, SMS. Viber just going to re-enter.
