Enable VoLTE and VoWifi on OnePlus 5

VoLTE (Voice over LTE) delivers voice calls over the internet. It is a digital packet voice service with many benefits for mobile operators and consumers.
Here are three main benefits for consumers:
- supports higher quality calls
- connects calls much faster (lower latency)
- improved battery life.

You can use VoLTE only if your phone and network support it.
My mobile network (Telekom Slovenija) supports it and VoLTE enabling is easy in the web dashboard:


The second part was enabling the VoLTE feature on the phone. Almost all modern phones support it, but some of them don't have this feature in the menu. My OnePlus 5 didn't show it (this depends on some reasons), but I knew that it is supported. Here is a simple tutorial on how to enable it.
The process is quite simple but be aware that something can still go wrong :-)

1. Open the dialer on your phone and type *#800#
This will start a special OnePlus app which is usually used when OnePlus service team try to help you with problems. Don't worry, press Enter to start the magic :-)
2. Click "oneplus Logkit":


3. Click "Function Switch":


3. Enable VoLTE (and VoWifi if you wish):

And then restart your phone. This is important!
After the phone comes to life, go to "Settings -> Wi-Fi & Internet -> SIM & Network" and there should be a new feature (or two of them if you enable VoWifi beside VoLTE):


That's it. I hope this short article will help you if your OnePlus doesn't have a VoLTE feature in the settings.

Izotov fotografski kotiček


Čisto na kratko. Pred  kratkim sem pripravil spletno stran in jo opremil z nekaterimi svojimi fotografijami. Gre za izbor, ki je bil čisto stvar navdiha v urah, ko sem sedel za računalnikom.
Morda bodo komu fotografije všeč, lahko pa, da gre za popoln strel v prazno.
Nič hudega, fotografiram predvsem za lastni užitek :-)
Če pa komu katera od fotografij polepša trenutek, je pa še toliko prijetnejše.
Vabljeni k ogledu: Izotov fotografski kotiček

Vesel bom vaših pripomb.

Google Maps' AR (augmented reality) navigation

Google Maps AR shows where to turn left

Google Maps (check my review) is the most used navigation software and users constantly expect improvements and new features.
In last weeks some of the Google Local Guides get a new feature in Google Maps - AR (Augmented reality) navigation. Augmented reality isn't available to everyone.
But when this feature appeared on my phone, I knew that it is time to try it immediately in real navigation (AR walking navigation).
The feature is still in a testing period and is labeled with "preview" strip on the right upper corner. Besides that, an application asks you for experience after navigation.

At this moment Google Maps AR helps you when walking. Using it, you won't walk in the wrong direction until realizing your mistake and wasting your time searching for turn points.

For AR navigation Google uses a method named "global localization". It combines machine learning and Visual Positioning Services with Street View.
I was skeptical if this will work in Slovenia, but I was surprised that it works very good. At least in Ljubljana and Koper where I tried it.
If AR navigation can't find known buildings and landmarks, it will offer to use regular navigation instead. While walking in Koper, it works surprisingly well. Even in narrow streets.
Usage is simple - press an "AR Start" button when using walking navigation. Then point your phone's camera at surrounding and an application identifies the known points (landmarks).
It will draw navigation-related information (direction, distance...) on the phone's display.
The bottom of the screen still shows an ordinary Google Maps view. The application also shows a warning to keep your phone down while walk. It is usually enough to check the phone screen only from while to while. Just rise your phone to check if you are on the right way and then you can keep your phone down while walking forward.
It is worth to mention that AR navigation works surprisingly fast and can be used without delays if you have good light and internet connection. Yes, I said good light, because using AR navigation at night still has problems.

It is also understandable that battery consumption is higher than with a usual 2D navigation. The phone does get pretty warm too.



I don't have no idea when this will be available to all users. I'm a Local Guide and Google Maps Beta tester and some features are available on my phone earlier.
There are some clumsiness and ambiguity. And a question - is this usable?
Technically speaking, it is clearly labeled with alpha version and we can expect that things will improve. But - will people use AR instead of usual navigation? It has potential. Maybe AR will show additional information on the screen. That would be a nice add-on. Using AR with smart glass? On cars Head-up Display?
What is your opinion?
