[MTCD  Android Head Units Q&A] royalhawk2002:
Thanks. Could you please provide a link to your post?

Did you add ferrites to the usb or to the car harness?

My antenna is on the roof, a shark fin type, with GPS, fm radio and dab. It is very far from the head unit...

In any case I don't think the issue is on the antenna, because I did some test with the dongle attached to my note 10 and a different antenna.

The interesting thing is that with this setup I have an unstable signal while I seat inside the car, when the head unit is on, but instead I have full signal going around inside my house. I was expecting that in the car was better because I am out in front of my house.

See the picture for the setup.

I will do other tests in the afternoon, if I can.

Moved the dongle in the box helped a bit. Now I have a better signal strength but is not the max. Same dongle, with same antenna connected to my note 10 with HU switched off, give a much better signal.

I put a clamp on ferrite round the USB cable at both ends, but in hindsight this didn't do anything.

I think your problem is exactly the same as mine, the head unit backlight emits noise at DAB frequencies, you could test that, connect your DAB dongle to your Note 10 with the Xtrons head unit off, it works correclty. Now switch the head unit on and see the signasl drop on the Note. Now turn off the display on the head unit, signal comes back.

Wrapping the head unit with copper tape and earthing it really made the difference in my car.

Good luck,

Robin
[MTCD  Android Head Units Q&A] royalhawk2002:
Thanks for the info. I already made the tests you suggested and everything is confirmed. I will try first to identify and shield the internal power supply for the lcd, I have a schematic and I have an idea on where is located. Then, if it doesn't work, I will proceed to shield the head unit. I will do pictures to help other users.

[MTCD  Android Head Units Q&A] DrRobin:
That is fantastic. I have 2 Xtrons units in two cars, an older Android 8, that doesn't cause any interference and the newer featured in the post which creates terrible noise around 200MHz. I did some looking and found that LEDs and their PSU can be noisy at these frequencies, so I guess the later Xtrons units are just a problem. It is not good that they sell a head unit and DAB stick that creates so much noise to make it useless, I did contact them and sent them my findings, but didn't get any sensible response.

Since the noise was coming out of the screen I thought it would be difficult to get rid of unless I put a screen rfi filter on and then the touch screen probably wouldn't work. I did notice that if I touched the metal case of the Xtrons unit with my hands the noise dropped a little, so assumed that it wasn't very well earthed. I tried the copper tape not really expecting it to work, but had to take a piece of tape to bare metal to get a good earth. It took a couple of goes to make sure the head unit and cradle were really well earthed, but the results were fantastic, the noise dropped away to almost nothing on my spectrum analyser.

Unfortunately I didn't get any screen shots from the analyser, but used a SDR-Play to view the spectrum, although a cheap DTV USB stick would also show the same thing if you have one available?
[MTCD  Android Head Units Q&A] royalhawk2002:
Yes I have the sdr dongle that I am using for my tests. See pictures in above posts. In any case I am thinking to shield the backlight psu with a sheet of metal soldered on the nearest ground point. I will try also to use shielded wire as much as possible inside the unit, exchanging the actually installed, if not shielded. Another test I would like to do is to change the source of the antenna amplifier power...actually is connected to the wire coming out from the hu...probably the 200 mhz interference is transferred to the outside antenna with that wire, contributing to attenuate the signal.

[MTCD  Android Head Units Q&A] royalhawk2002:
Today I had the time to make the work. So I did;

1) locate the LED power supply. The problem was not in the power supply, but the LED panel itself. I did some measurements with the spectrum analyser and I found that the highest strength of the interference was coming from the around the screen where the led strip is located and not near the power supply.

2) Noted that the lcd controller board is mounted on the back of the screen without any shield. Then I decided to shield first the board and connect it to the chassis.

3) I put a plastic foil molded on the board to insulate it from the shield. Before that, I fixed a screw on one of the board holes that are connected to ground.

4) Then I put some aluminium tape all around the board, also on the plastic sides of the screen frame. The screw in step 3 was connected to the aluminium shield.

5) connected a wire from the screw in step 3 to the chassis.

6)Covered almost all the unit with aluminium tape, taking care to make all the strips touching one to the other in order to have one whole shield as result.

7) switched on the unit and...no more interferences found even at max screen intensity.

Hereafter some pictures. Now i have the signal strength to max. Hope it helps. I want to thank [MENTION=10471615]DrRobin[/MENTION] for the suggestion.View attachment 5031393View attachment 5031395View attachment 1View attachment 5031397View attachment 5031399View attachment 5031401View attachment 5031403View attachment 5031405

[MTCD  Android Head Units Q&A] ab1702:
This is brilliant that you found this source of interference and actually fixed it.

I have a GS px5 unit now with the same problem but I have installed a powered roof antenna which now gives me full signal.

I did once try a shark fin antenna on the roof but it didn’t work which must be because of the interference and I would actually still like to have a shark fin antenna so I think I will do this shielding that you two guys have done.

Did either of you try just shielding the back of the screen to see if that fixed the problem before you installed your ground connections and covered the whole units in tape? The reason I ask is because it is the cheap LED lights that they will have used that will be causing the problem. If they would have used some certified LED lights then they would have had shielding on them and wouldn’t have caused any problems.
[MTCD  Android Head Units Q&A] royalhawk2002:
Look at points 1 to 3 and to the second picture above.

I have a shark fin antenna, for fm, dab and GPS and it is working well

Inviato dal mio SM-N970F utilizzando Tapatalk
[MTCD  Android Head Units Q&A] ab1702:
What I mean is when you shielded the board/screen did you then try the dab to see if this had eliminated the inference or did you just connect it the chassis straight away. Does it definately need that connection to the chassis is what I’m getting at?
[MTCD  Android Head Units Q&A] royalhawk2002:
No I didn't check with only the screen shielded...since the unit was dismantled then I decided to shield everything...just to be sure

[OnePlus 8 Pro Questions & Answers] Expozen:
Hello,

Thinking about getting the OnePlus 8 pro

So far I've used Samsung or Huawei Phones, and they both have a feature I really love the SecureFolder on Samsung phone and the HiddenSpace on Huawei Phones.

It's just like having 2 phones in one, so I can use it both as a work phone and a personal without mixing anything between the two.

Does the OnePlus phones have something similar?

I'm not looking for and app, Iv'e tried dual space and similar apps.

they just make cloned apps, but I'm looking for a total and discrete separation between the two "users"

different contacts, files, apps, everything ;)

Thanks,
[OnePlus 8 Pro Questions & Answers] cultofluna:
No

You have the option to secure files or foto's through stock file manager app or stock gallery, or to lock a specific app with encryption..( fp, pattern etc)
[OnePlus 8 Pro Questions & Answers] efex:
I might be entirely wrong about this one, but I think we can create a "locked" work profile on the phone using apps like Island to create it, and keep that part of the phone encrypted. It should be possible to keep that partition secured with a separate pass code. Not as convenient as "SecureFolder", but might be enough.
[OnePlus 8 Pro Questions & Answers] Expozen:
I have tried Island but it seems buddy and crashed alot

I know on some phones you can create a different "user" like on windows, is it possible?
[OnePlus 8 Pro Questions & Answers] efex:
That's pretty much what Island and that type of apps do. They create another user with ID 999 so the apps on it can be heltd separated from the "normal" ones. Afaik there is no built in separate user space in android, other than work space capabilities. If Island doesn't work well for you there might be other apps of the same type, perhaps Shelter works better (I don't know, Iäm not using apps like it myself).

I've got an O2 XDA Stellar on PAYG and I've bought the £7.50 "Web Bolt On". Thanks to a CAB I downloaded somewhere I've now able to view the web pages, but nothing else works: IMAP, MSN, weather updates etc. Needless to say I didn't pay 7.50 just to squint at web pages on a tiny screen!

Does anyone know if it's possible to get these other services working and what I would have to do to configure it?

If not I suppose I'll have to abandon my call credit and ditch this mob for 3!

o2 pay and go do not offer the full internet to their customers, you either have to upgrade to pay monthly or get a contract, or have as you say , a half baked version of the net where you can only surf some web pages and not be able to use msn or email etc.

I wouldnt bother with 3 either as they are pathetic, half the time you cant even get a phone signal ,let alone a 3g signal.

Have you TRied the O2 Simplicity Package which can include Web access

Hi Guys,

Have you heard of th O2 Simplicity Package offered by O2?

I went from an O2 pay monthly contract to the Simplicity Deal.

You are commited to 30 days only.

I pay £20 per month, I receive:

400 any network voice minutes (i often select my 3 montly treat as 20 extra minutes to bring it up to 420 mins),

1000 Text Messages

UNLIMITED WEB ACCESS FROM MY PDA!!! as a free bolt on.

I was originally offered umlimited O2 - O2 calls. But later opted for the free internet as it was more of a cost saving for me.

And I get the full access with my web settings.

You will find it on the O2 Website, well advertised as the Simplicity plan at different levels.

While we are on topic of settings - need a serial number

Hi again folks,

While we are on the topic of web settings.

I have just bought an HTC TYTN II, I would like to install the O2 Windows Mobile 6.1 ROM, I prefer the O2 ROM as all the settings are pre-programmed and the layout are as O2 expect them so I can call them for Tech support.

Unfortunately, I cannot access the file as I don't have the O2 version (the XDA STELLAR) and you need to enter your O2 XDA STELLAR Serial Number to access it.

Is there any kind person out there that might be willing to PM (message) me with a serial number of an XDA STELLAR that I could enter to get the file please.

Hoping someone can help me,

Thanks Folks,

I have just bought my first Huawei phone. This is a Nova 5t model. Today I downloaded the Nike training app, I use this app for about 3 years, it was working well on Samsung. Now when I want to log in,after I added my loging details the app seems to frozen then asking quit, wait or send feedback.

So I am just wondering if you know any similar issue with Huawei? I am thinking to exchange for a Samsung A51 instead if I cannot solve this issue.

Can I trust in Huawei? I have no any experience with this brand.

It's a service set up for any track and trace app that you use to help your country battle Covid 19.

Nothing suggests it's spying or extracting data unless you have the app and giving your device permissions to communicate with the app's servers. Once you do, that data will be collated to assist with the global fight against the disease.

[OPPO Reno 10x Zoom Questions & Answers] moozer:
As you have no app to trigger the service... there's no issue. This is a global pandemic and the two companies are right to help in the containment. Your data is not at risk. Your privacy is not at risk. The app and service are controlled by you. Opt in if you want...otherwise, it's as you were
[OPPO Reno 10x Zoom Questions & Answers] Schwarzie2k:
And for that i have what confirmation? Googles word? Googles trackrecord in regard to privacy and data proterction is nothing that would put me at rest.

Also company that has just shown that it can even install **** on my rooted Androidphone with customrom without asking permission.

So, has anyone already found out how to remove it?
[OPPO Reno 10x Zoom Questions & Answers] moozer:
You have Google and Apple assurances that YOU have control SHOULD YOU decide to install the COVID 19 track and trace app.

Note: this is a global response and as such Google AND Apple have rolled out this service. Do you need permission from coronavirus to infect your immune system? No. It takes over regardless. Same here. The fight against this disease will go on with or without your permission. As I've said a few times, this is a service to respond to a global threat and a containment response. YOU DO NOT have to install anything to trigger the service unless YOU want to. It will remain dormant until activated by any Covid 19 tracking app that YOU CHOOSE to install.

Simple.

It's all about your own choice

If you're that paranoid about security...reach out to Google AND Apple and ask them.
[OPPO Reno 10x Zoom Questions & Answers] Schwarzie2k:
The assurance of a known liar has no worth. The only currency here is trust. And both Google and my (the german) government have a horrible trackrecord in regards to trust., especially when it concerns privacy or the assurance that they wont creep in more functionality once the basics are installed.

And im still shocked that google can simply install whatever they want on my phone. More control about my hardware was a major decision point for a customrom with root on my end.
[OPPO Reno 10x Zoom Questions & Answers] moozer:
Imagine having a trackable and identifiable footprint in your phone.

Oh....wait.

Anyway...as I said...reach out to Google as it seems reasoning with you is out of the question now. I tried being diplomatic but it just keeps becoming a contention.

On a separate note...
