I've had the same issue and solved it fortunately.

My Unit is a Joying RK3188 and came with a defect dual input power injector.

Easy steps to identify: At the output of these injectors (called 'phantomspeisung' in german) you sould measue 12V DC. These 12VDC sent over the 2pol antenna cable are for the antenna built in amplifier.

1st: I replaced the power injector with a diversity injector. Google for "Diversity Adapter 204.086-0) www.rta-online.com

2nd: Additionally to my amplified roof antenna I bought a second amplified antenna at amazon

http://www.amazon.de/Baseline-Conne...enne+AM,FM,+inkl.+Verstärker,+FAKRA-Stecker+F

Both together I've a really good reception now.

The diversity adapater really makes it's job. I is a littel high in price but worth at all.

Try putting some electrical tape around the Motorola male antenna plug at the head unit. What you are trying to accomplish is to insulate the area where the head unit housing may be in close contact with the plug. Takes a few seconds to try.
[MTCB Software Development] markusmuster:
...that's excatly what provided the very worst reception ever to me... So I looked around (tried a lot and spend some bucks on some useless amplifiers) and finally found the solution from my previous post. It works. ;)
[MTCB Software Development] pounce:
If putting insulating tape just around the plug where it would touch the housing (and not where the actual plug needs to mate up) gave you worse reception... you did something wrong.
[MTCB Software Development] dazza007:
I was under the impression that these units had issues with the software ( or hardware) or this is what I am told.

See here or am I mistaken?
[MTCB Software Development] pounce:
Its possible you are mistaken. The OP in this thread didn't provide any hardware specific details. Instead we know only version of android.

My units have no problem with radio reception, but I can simulate a problem if the connector touching the housing and impacting reception.

Other issues are not connecting the power to a stock antenna from the head unit when you install it. Even if you don't have an antenna that goes up and down you can have an amplified antenna. If you don't power it you don't get good reception. it can be something that is missed with wiring up the harness.

Yes, you can also have hardware problems, but its easy to rule out the external issues first before calling the unit the problem.
[MTCB Software Development] dazza007:
When you quote "my units have no problem," what software and hardware do you have in each, which motherboard, radio chip, etc etc

I part of me would like to believe that insulation is a problem here, but guys on the Russian forums have replaced capacitors to improve reception.
[MTCB Software Development] pounce:
I have Joying units. One of the 10.1" universal units with 3188 and a 7" universal unit with 3188. No idea about the specifics of the chips.

If you have a specific hardware unit that people are complaining about then you may have a problem with that unit from that manufacturer. That's realistic, but try the other tests first before performing surgery.
[MTCB Software Development] Speedyp:
Problem is most likely a internal problem with the ground of the antenna input. This was the problem with my unit.

This is great. It really helps illustrate how people are interpret things differently.

You have put too much tape on the connector. You have essentially broken the connection by entirely covering the outer connector. It may not be been obvious to you that a motorola antenna connector needs contact on the pointy post and the outer shell.

What you wanted to do I carefully put just a little tape on the plug where is could touch the case of the unit in a circumstance where the alignment of the female connector inside the case attached to the PCB isn't perfectly centered for the case hole. When things are out of alignment there tends to be a connection between between case and the outer shell of the connector. When these things touch it can negatively impact reception.
[MTCB Software Development] markusmuster:
Hehe... I made this photos this morning with an unused plug just to illustrate. I know that the connection is broken when insulated and also the it's impossible to work this way.

I also read several threads about that "put some tape on it" thing and heard dozens of interpretations.

A picture tells more than some thousand words.

To clarify that to all of us: Please be so kind and make some photos !

Thanks in advance!
[MTCB Software Development] pounce:
To illustrate how you did it?

So did you do it correctly when you tried it on your unit or are you saying this now to show the mistake and now you understand you need just a little bit of tape like mentioned up thread?
[MTCB Software Development] jakejm79:
You might have a grounding issue if you are having to do that. I believe another member noticed that the outer part of the antenna socket is internally grounded with a little bit of solder and some foil, he had noticed that the foil had become disconnected meaning the outer part of the socket was no longer properly grounded, insulating the plug like you have done would help in that situation, but it isn't the correct fix, regrounding the socket is.
[MTCB Software Development] pounce:
You may have read up thread.

1) Check the connections like power for the antenna if you have that

2) check the plug to see if its contacting the case. Tape as needed.

3) Open the case and validate the connection to the female socket on the PCB.

4) Check your MCU firmware

5) Try another unit
[MTCB Software Development] hallo dare:
This whole tape thing has me so confused. The outer shell of the Motorola plug has to touch the casing for earthing doesn't it? Yet you are saying to tape up only the bits that are touching the casing.

Totally confused.

Can someone put up a picture of what is the right way to tape it please.

I would have done exactly the same as markusmuster has in the pics.

Thanks
[MTCB Software Development] pounce:
Case = Double Din aluminum case with all the electronic bits inside

Motorola female plug = socket for the antenna that is attached to the radio circuit board inside the case (see above). You can see that there is a hole in the case (see above) where you can see the Motorola female plug.

Motorola male plug = the pointy plug on the end of the antenna cable. It has a pointy end and an outer shell that is the ground for the antenna.

Do this... shove the male into the female plug through the hole in the case do its firmly seated. Step back and have a breath and maybe a smoke or some ice cream. Now go back and look carefully at the plug still inserted through the hole in the case (see above) and see if you can spot any of the motorola male plug ground surface touching the case (see above). If you see any contact between the plug and the case (see above) note about where the motorola male plug would be touching the case and yank that sucker out of the female plug clearing the hole in the case (see above). Now that you know about where on the motorola male plug the case (see above) would be touching put some tape on the motorola male plug ONLY in the exact spot where the motorola male plug would be touching the case (see above). You do not want to extend the tape down the shaft of the motorola male plug in such a way that it would in any way interfere with the lovely fit that motorola male plug has in the motorola female plug socket found inside the case (see above).

Better?
[MTCB Software Development] hallo dare:
Ah nice one. It's where the shoulder of the Moto plug meets the case.

Thanks
[MTCB Software Development] hallo dare:
Just an update. Done as mentioned above. no real improvement.
[MTCB Software Development] pounce:
If you didn't have metal to metal contact with the male plug and the case prior to the tape addition there would be no change.

I have some problems with radio as well but in my case looks like that. For few months worked everythink good but in last few weeks...

One station working fine all the times. Another stations yesterday evening worked ok with good reception but today morning not working but this one station were with good reception. Anybody know what is going on?
[MTCB Software Development] germinus:
I also have a problem with reception on one of my HU's , with the ignition on I get perfect reception but as soon as I start the engine I can't even pick up a local station.... Any idea's?
[MTCB Software Development] rgviewer:
I also have poor reception on FM. I read to hook up blue ANT/Con wire to factory antenna amp. But I do not have an antenna amp. Do I still hook this wire up to anything. I heard these units need an active antenna, but I am thinking my car being a 2003 Ford Escape does not have any factory antenna amp. I have tried the tape on end of plug and didn't see any improvement.
[MTCB Software Development] Geniee33:
I too have very poor AM reception, on a 2009 Rav4 with a regular male antenna plug, i just plugged it in.

The powered Amp Antenna blue wire from the head unit, i didnt connect to anything because i didnt have a powered antenna or need a way to trigger an up\down antenna.

Does this blue wire need to be soldered to anything? I read about power amplifying a radio signal but unsure on this?

Hello guys, i´m going to dig up this topic to ask for help

i have an android auto unit on my Mercedes Benz c220 (w203) and i have some issues with the FM reception, i already put an antenna amplifier and this job was made by an certified technician.

the problem is that if i listening one radio station and if the AF (auto frequency) is on, sometimes he jumps to another station e after some seconds he returns to the original one, other thing is the reception is very bad, i heard many noise and is very boring to hear music this way

i already put the FM sense to the minimum and there was no improvements

any solution ?

thank you
[MTCB Software Development] mclaudio:
[IMG="photo"]https://incartec.blob.core.windows.net/products/4749.jpg[/IMG]maybe you dont need amplifier but a relay

i had this problem on my car...amplifier improoved but was not the solution

some cars have 12 v powered antena, this means that you must give 12 v TO the antenna. Amplifier, amplifies what COMES from the Antenna.

so try a fakra 12v adaptor

search on ebay or alliexpress somethink like this

bassically you should connect the connector to your can antenna and the aerial connector to the radio, the single wire to 12v power.

that worked for me
[MTCB Software Development] cookies2388:
hi mclaudio

Does that connects to the RF 75 ohm connector?

i talked to the guy who installed me the antenna amplifier, and he told me that the radio processor in the tuner is a little bit weak and there isn't so much things to do but after install the amplifier i had some improvements, for example, when i turned the lights on there was much noise and now there isn't .

i believe is better to wait for dab+ radios in Portugal, but that is going to append when we get 5G

until that i´m going to use internet radio

thank you
[MTCB Software Development] mclaudio:
Hi

i am also in Portugal :) i had big problems before but with that adapter no problems...

DAB in portugal? i dont think so :(
[MTCB Software Development] cookies2388:
oh, okay, i didn't noticed that :laugh:

honestly i tried everything and I'm still with this problem and that relay you showed me connects to the RF 75 ohm connector, and i tried a few moths ago something like that, and didn't work, catch one station and with a lot of noise

i talked to a specialist and he told me that German cars for the most part are tricky, because the location of the antenna, mine for example is the rear glass but everything depends on the quality of the processor that is built in the tuner, a bad align tuner always work this way

Yes Portugal will have DAB+ when 5G arrives, in Spain for example there is 5G and DAB, notice our mobile operators are doing something in the antennas i´m catching mobile net in places where i didn't get in the pass and i´m Vodafone

tks
[MTCB Software Development] _Vin_:
Hello,

I'm also from Portugal with an unit with bad reception. I made an research regarding DAB radios and it existed only with some radios of RDP (antena 2), it was discontinued long time ago. And I do not think we will have it, otherwise it would be on the news all the time like the TDT. DAB do not work with normal equipment we would have to bough a new one or an adptor.

[HTC Hurricane] philhaz:
My SPV C550 (HTC Hurricane, Windows Mobile 2003 SE) has never had any trouble synchronising data with Activesync on my XP desktop PC.

Now that I have a Vista (business) laptop, I am forced to use WMDC (Windows Mobile Device Center). I plugged in my phone via USB, and after briefly showing up as an "Unidentified Device", Vista found the driver automatically and installed it as a "Smartphone USB Sync" (version 6.1.6965.0). Leaving it plugged in, I then installed WMDC version 6.1. The main GUI came up, and my device connected successfully. I'm able to browse the contents of the device and the storage card, and also add and remove programs.

The problem is that whenever I try to sync my Outlook 2007 data, the response from Vista sync center is merely "Sync Failed". The error proerties window is blank, other than the date and time the error occured. When I disable all options (contacts, calendar, tasks, email) bar one, the error properties window states "Contacts: Attention Required", where "Contacts" is whatever I left enabled. None of these errors appear in the system/application event logs. Disabling all options produces a "successfull" sync, but as you can imagine this is not of much value to me.

I am not using any kind of firewall software (including OneCare), and all the required services are running (including "Windows Mobile-based device connectivity" and "Windows Mobile-2003-based device connectivity").

Another device (i-mate JASJAR, Windows Mobile 2005) was able to sync successfully first time with no problems at all.

I have so far tried:

- Restarting the laptop

- Soft resetting the phone

- Plugging the phone into different USB ports

- Deleting and re-establishing the partnership

- Reinstalling WMDC

- Reinstalling Office 2007

- Updating the driver for the "Smartphone USB Sync" to various others (both from HTC and Microsoft).

- Hard resetting the phone

All have produced the same result: "Sync Failed". Now I'm out of ideas, and I'd really appreciate some suggestions on this.

[HTC Hurricane] foxy9:
i have had a lot of grief with this too as has 1000's of other people. Ive trawled through threads on various forums and there seems to be no guaranteed solutions.

I have a HTC HD touch and i am never confident of being able to place a tick in the boxes for syncing outlook items.

For a while, going into control panel and 'repairing' wmdc worked, with the device unplugged. but that stopped working too. A complete uninstall and reinstall of WMDC seems to be the only way to ensure a reasonable chance of everything being tickety boo. However, even that sometimes doesnt work and that requires a good half hour of my time.

I would be interested in knowing the actual process that the syncing does, as it must be intererupted by something in order for it not to work consistently. Microsoft itself hasnt an answer and just advises reinstalling. I know it looks at the outlook pst file but how it processes it, i am unsure.

In order to not lose all my contact details on the phone i now have them all saved to my sim, but losing the emails, tasks and calendar on my phone, is a real pain.

Perhaps one day someone with the tech knowhow will make a project of this and we can all benefit from having 100% confidence in things happening when we plug in that usb cable.
[HTC Hurricane] acudoc411:
I have the same problem too

I haven't found an answer. Has anyone resolved this?

HTC says that they are aware of it and are taking it very seriously (never a good sign) and that they plan on having a fix for it someday (also never a good sign), but the don't have any idea when (a really really bad sign), and were unable to even give a time range for it being fixed.

I really like my TP2, but at the rate I'm going with it I'm ready to give it flying lessons. :mad::mad::mad::mad::mad:
[OnePlus 2 Q&A, Help & Troubleshooting] Pipper:
Hello, sorry if this has been posted before. I search but didn't find the same issue.

I just bought a OnePlus 2 from someone. Before buying the phone, since my T-Mobile sim card wasn't a nano sim card, I inserted a new, unactivated T-Mobile nano sim card and was able to see cell signal bars and successfully make a test call to 611 (customer service). However, after I bought the phone and got my sim card converted to a nano sim card, I couldn't get cell reception at all. It kept saying No Service no matter how many times I tried reinserting the sim, rebooting or resetting the phone.

So I thought it was a ROM issue, and proceeded to upgrading from stock Oxygen OS to SkyDragon Hydrogen OS. After installing SkyDragon, still No Service. Then I thought there must be something wrong with the modem firmware, and therefore flashed this modem I found in the SkyDragon thread.:

http://xdaforums.com/showpost.php?p=65329394&postcount=546

First reboot after flashing the new modem, signal bars appeared, and T-Mobile showed as the carrier BUT making calls and using cellular data failed. Rebooted the phone, and it went back to No Service.

Is this an issue with the modem? Should I flash another modem? Please help. Thanks in advance.

The "focus effect" is available but not panorama mode nor photo sphere.

Camera version is 2.5 while the latest version according to apkmirror is 3.1
