[Completed] frequency - XDA Assist

i am using smartphone. when i open radio app in the device i can enter frequency b/w 80.0 megahertz to 108.0 megahertz. Is it possible to enter frequency which has 8 decimals (example: 89.32165487 megahertz)

Hi,
I very much doubt that. It's for FM radio and it doesn't work like that. Nor would it be helpful, as FM stations use one decimal place.
You could contact the app developer to confirm. Or if it's an app that came pre-installed on your device, you could ask in your device section..... I would guide there, but you didn't state your device make and model number.

FM Radio Question

Does it annoy anyone else that it is impossible (as far as I can see) to allocate a meaningful label to the presets on the FM radio application so that all you can do is store them by frequency number?
If I have 10 presets set up it seems so obvious to me that I would actually want to see them as things like "Radio 1", "Radio 4", "Capital", "Virgin", or whatever rather than <xy.z>MHz and have to remember what station is on what frequency/preset.
Are there any third-party FM apps that can talk to the HTC hardware? I know there are lots of apps out there to listen to streaming internet radio but since the tuner is hardware specific I suspect the app that drives the FM tuner is probably HTC-specific and written by HTC. I'd love to be proved wrong or for someone to tell me that I've just not seen the feature to allow me to assign a label or that there's a registry hack or something.

I can't help here as I'm still waiting for the O2 version but, I thought this phone supports RDS. Is that not true? And if so, doesn't it automatically name the stations it finds?

It does support RDS, and it works in the UK, but unfortunately the RDS data is only displayed once you've tuned into the station and it doesn't save the info against the preset so there's no way of using the RDS data to decide which preset to select in the first place.
This isn't a huge deal, it just infuriates me because this is such an obvious feature and I just think it's a bad piece of software design.

Can Android device transmit radio frequency?

I have gone through many articles in the internet but couldn't find anything related to this. I wanted to know if android has the capabilities to transmit radio frequency so that it can be used for playing the songs in the smartphone directly to the nearby radio by making the smartphone as a radio station.
Yes, but you need some external RF hardware - check out GNU radio and the general subject area of Software Defined Radio.
Hmm I know some Android Phones may have it build in a Hardware for.
My "old" Nokia Phone have that native feature.

How to check CPU health of a used smartphone?

I'm up to buy a used Samsung Galaxy S9 and wondering about how can I check it's processor health.
Let's say, the person from whom I am buying has intensively used this device for high graphics gaming, etc.
And, do smartphone processors really age like Computer's do?
PS: Yes, even in 2021, I still want this phone.
AFAIK there´s no way to check the health of a CPU ( at least not on consumer level ).

What about stress testing? Is this any better than nothing at all for an estimate of CPU health/performance? And, is it reliable?
IMO this only makes sense if you can do the same test on a brand new device of the same manufacturer / same model, so that you can find differences.
It's your decision to waste your time with this ...
EDIT:
Have AndroidStressTest apk atteched
Go to setting / about phone / build number. Tap build number to turn on developer option.
Now under developer option find SHOW CPU USASE.
You can check usage of CPU. There are android app for processor testing.
You can use diagnosis tool of android mobile. Use *#0#. You will get Display test, sensor test, hardware test and more test.
For desktop computer you can use Intel processor diagnostic tool.

Question Alternative FM radio app for FYT-based Android head unit

Hello all,
I have an Atoto S8 which is a FYT based Android head unit.
MCU Version:
2021.04.26 13:48:17 YUF_53_L6315_G32P64F64_Ver: 1.0
CPU: UIS7862 Octa-core
I was wondering if anyone knows of or has an .apk of an FM radio app compatible with the FYT head units? I tried every app around and none of them work. The Navradio developer is still porting his app to this platform, so I was wondering if there's something else I might try meanwhile.
There are re-skins, but AFAIK the radio bits are part of the proprietary MCU
But if I got an .apk from a Joying head unit, it might work no?
I'm not so sure about that.
I think you would have to do some hand editing of some files at the very least. (To put in your fyt build number)
There is more info on it at the other forum.
I looked into it for a second weeks ago, but then I bought Poweramp and haven't really used anything else.
I agree that the fm radio all looks like crap though on my Mekede
Poweramp works with online radio?

Apparently it does. That's not what I meant, though.
I procured some 15-30 gigabytes of songs from different playlists from another source.
(I have to be vague because of forum rules)
Anything else I want, such as podcasts, I just stream via Bluetooth.

If your Atoto S8 is indeed a FYT unit, it might work.
What you carefully need to look at is the name of the apk. It has to be exactly the same as the one on your Atoto unit including installed libraries.
And then you need to write the corresponding lsecupdate.sh file and use the corresponding lsec6316update binary
and off course: make a backup of your current one.
I'm working on porting NavRadio+ to FYT units.
This last weekend, after 2 months of tries, i was finally able to get sound out of my app.
I already have control of the radio commands and infos so it's just a matter of put things together in the right way and iron out all bugs. Then i could release a first FYT version probably in the first days/weeks of the new year

I did not know you were working on this.
Please take a look at this github from lbdroid. It contains a lot of useful "reverse engineerng" information for the MCUradio for the FYT. It is still from the Sofia3GR but as far as I know hardly anything changed.

The original fyt radio app now contain code for all the platforms and each platform use different approaches. The hard part was to understand which part of code is used by each platform and how.
Sofia units control radio and audio through MCU.
UIS7862 use the native jni libs to control the radio and audio is started by MCU.
Right now I'm working only on more recent UIS7862 units, i don't think I'll adapt it to Sofia or other older units.
I know that units with canbus use another APK too (com.syu.carradio) but it's not totally clear to me what it does exactly. Can somebody explain me it?
To make my app to work, because of the native libs, is mandatory to install in OEM folder a copy of NavRadio apk (not necessarily the full apk, even a fake app with same package name is enough to set NavRadio as system app).
To do this i have 2 ways:
- directly from NavRadio for rooted units with some root commands
- downloading a zip update package to flash manually the APK in OEM folder
If you guys have other/better ways to do this, please tell me, I'm new to these kind of units..

I did "some" checking on this app a couple of years ago as I had a Skoda with Canbus. The standard radio in the Skodas (and I assume in all VAG concern cars) are partly controlled by the CANbus. The Skodas use an extension on the standard CANbus commands to switch on/off the radio in the cars when ACC is switched on/off. This is NOT a direct wired coupling of power, but really a digital on/off signal from the CANbus.
My Skoda had a simple Swing radio (hence another Android unit), but other Skodas had the MIB1 Amundsen/Columbus unit (navi/media/phone/radio/tmc and car menu). The car menu inside the radio is also controlled by the CANbus. My guess at that time (not having a MIB1 amundsen/columbus unit) was that that was also "streamed" through the carradio app.
Note: I am only sure for the on/off, the rest is an educated guess. And I assume other cars with CANbus displaying/changing "stuff" via the radio, instead of dedicated hardware buttons, do the same.
Maybe other users having a VAG (Audi/VW/Skoda/Seat) car with previously an MIB1 (or MIB2, but why replace that one?) unit and now an Android unit might have more info.
Please share.
And another question: RDS-AF on all FYT units is incorrectly implemented and already since early 2016.
Does your app has a properly working RDS-AF?
If I drive in the Netherlands from North to South (or the other way round ), I sometimes go through 7 (!) frequency regions depending on the station, but at least through 4.
Working RDS-AF functionality would really be THE reason to switch to it.
Edit: I know it works for Topway and the like, but I want to know whether it also works for FYT.

Normally AF is handled directly by radio chip. I still haven't investigated how it work on fyts.
My app can only enable/disable AF and on some units you can set the sensitivity of reception.
On MTC units that also receive the radio station ID (PI code) i added a function to merge the alternative frequencies in the same station preset in an array so that you can easily switch between them sliding up/down on the screen.
I can see in the logs that also fyt units receive the pi code but only at native libraries level (c++), i cannot handle it in java.
I know that we can change sensitivity and read the signal strength so probably something is possible to improve AF.
We'll see...

How is reading signal strength achievable?
Would be great to see real signal strength in app.

A lot of Philips TEF6686 radio chips are used and RDS is part of the chip. Some of the cheaper units use a TEF6851 which does not have RDS. Or the budget STMicroelectronics TDA7786x which does not have RDS either.
But it is still the software that "should know" how to retrieve and use the RDS info and in this case specifically the RDS-AF. The FYT software is not doing that correct.
That's why I switched in my other "deceased" car to a DAB+ module using @realzoulou's DAB-Z which uses proper "service following" (as RDS-AF is called in the DAB+ world).
That was a great solution, but I still prefer not to have extra hardware connected when it is not necessary.

I looked a bit at the logs during RDS-AF and it definitely is working wrong:
AF should search for an alternative frequency of the same station (identified by the pi-code), but somehow,after a while, if the signal strength is ok it switch to a station with a different pi-code.
All this seem to be controlled by the native library fmjni.so but i have no idea how to modify a c++ lib (maybe a revers engineering?)
Maybe I'll find some other way to handle AF using the logs but i can't promise anything right now.

I now think it even works differently for the standard FYT radio. My experience so far is only on Sofia 3GR (2 models), a PX5 and a sc9853i, no experience with the uis7862. Hopefully the uis7862 will arrive this week.
The RDS-AF only works for memorized stations. If I want to follow one station, for example NPO 2 FM, through the Netherlands, I need to add 4 frequencies (or more) and memorize these as presets.
It seems the radio app/mcu does not interpret the RDS-AF signal itself, but it seems to check (part of) the RDS data it has for a certain station, with RDS-data from other memorized stations. If part of it is equal (which part? only the station name itself?) with that other station (which you have to have memorized, otherwise it can't compare) and that station is stronger, it will switch to that station. If it can't find a stations from its memorized stations it seems to just select the strongest "whatever" station. This means that I have to blindly save 4 "NPO 2 FM" stations in the presets. And this for some other preferred stations as well. And of course: 1 frequency is what you can easily hear and set, but the other frequencies you have to google or so, because at the moment of adding it to a preset, you don't not have (sufficient) reception for that station.
"Real" RDS-AF should check the alternate frequencies inside the signal. Not do a "does some of the data look like a station I already have in memory".
I am a "restless" listener and listen to multiple stations. I switch when there is talking I don't like, a song I don't like, etcetera. I can't even memorize my five preferred stations in 18 presets.
In the Netherlands we have another deal breaker: FM frequencies are sold every five years and anyone can pay to it. It really means multiple different frequencies, whereas in some countries you only have one frequency for a station through the entire country, like in some countries in Azia.

I believe that standard radio receivers have a double tuner to handle the AF: one that keep the station tuned and one that scan all the frequencies to find the better one with same pi-code.
On MTC devices even if it's not perfect, it work correctly, the station is kept while the second tuner scan silently all frequencies until a new one is found.
On the FYT device i can hear changing frequency continuously until a stronger one is set.
I don't know yet if it try to tune the preset ones or try to find some other but anyway it's definitively not working correctly.
I'll dedicate more time to it after the first release of NavRadio app.
Right now on my app work like original app (so it doesn't work).
