Tried that and didn’t work. Copied both the 7z and the extracted files to highest directory I could (Local) and then tried a local Update pointing to each. Neither worked. Hmm
Edit. Rebooting head unit seemed to work. Found the update file and doing it now. Probably have to delete those files after
Not sure what items 6 and 10 with respect to added car integration and more advanced integration entails? Like more brands of cars? If so Nissan is left i the dust again.

FM radio alternative frequencies work in one direction, it searches for an alternative stops and does not return to the previous one.In my opinion it does not work properly, alternative stations should not be saved as an additional FM station in memory.FM radio and alternative radio stations work on the principle that the radio virtually remembers an alternative FM station and switches automatically.That's why it doesn't go back to the previous radio station because it doesn't remember the FM stations virtually. Previously, radio stations received better reception, now they fade out more often and do not receive signal.

Well, I don't understand what do you mean that it woks only in one direction, I haven't experienced anything like that in this version. Actually, there is no need to store the alternative frequencies anyhow, because AF list of the surrounding transmitters should be transmitted in RDS on each of the station's frequecny, so after switching to new frequency, it shoul load AF list from that transmitter.
Anyway, so far I didn't find any noticeable difference in AF behaviour between previous version 3.5 an now the 3.6 on my main unit installed in my car. I'm testing it also on my secondary test unit I have now on my desk in the office, I'll try to sum up my findings with the AF when I find some time to play with it....

RDS alternate frequencies (up to 25 according the standard) should be sent in the RDS metadata in the RDS stream transmitted by the station. The tuner doesn't need to "search". The tuner needs to check the alternate frequencies in the RDS metadata stream, while comparing it with the pi-code of that radio station. It can simply "jump" from one frequency to the next. So if it simply checks and encounters a stronger frequency, but having a different pi-code, it should not switch.
RDS doesn' t work correctly at the moment. It is a hit and miss.
Sometimes it works correct.
But sometimes you have a perfectly strong signal and suddenly it switches to a completely different station on a completely different frequency with a completely different pi-code.

jamar It works like AF before but it works badly. The station should not be saved on the list but should be remembered virtually like in any FM radio. Switches to an alternative frequency but does not return to the previous correct frequency. The alternative frequency should not be saved in the list with all stations but should be changed virtually. This is the first Android radio application where alternative frequencies are saved in a list with all stations. Navradio has the ability to add alternative frequencies but they are not saved on the list with all fm stations. They are saved virtually.

Exactly, well written. I'll just add that there are actually two methods of sending AF list in RDS, and with method B there can be sent multiple (max. 8) AF lists with up to 12 frequencies, so it can be used by stations which needs to send more than 25 alternative frequencies on single transmitter, or to differentiate between frequencies belonging to different regions, which can broadcast different regional programs at times. This is reffered as AF REG (or Regional) on OEM or big brands units. it is actually used by several multi-regional stations here, as I've observed... But, for now, correctly working simple AF without the B method would be huge improvement ;-)
By the way, as it seems by your description in the second paragraph, that you have similar experience with AF like I do, did you notice any difference with this in the 3.6 version? Since the AF optimalisations were listed in the changelog and after updating I'm experiencing still the same glitches, I thought maybe I need to do a full reflash with factory reset for the changes to apply corretly, but maybe there are not that significant changes and we simply need to wait a bit more for the devs to come back from holidays and look into this a bit more...
wybitny2
Ah, you mean that in the original Dudu radio application, when it switches to the station's other alternative frequency, this "new" frequency is stored in the stations list as a new preset. You're right, tried it now on my test unit (didn't noticed that since I'm using Navradio as my radio app) and indeed, when it switches to another alternavie frequency, it stores this frequency into the All list, even though you've tuned to that station manually before. This is of course wrong, and maybe this is the AF function optimalisation, listed in the changelog, but the devs got it a bit wrong ;-)
- Edited
Sometimes the same fixes or enhancements are mentioned in several changelogs. Sometimes it feels as if this is not another improvement, but simply not changed compared to the last improvement (or not) one sub-version earlier.
Normally I install a new beta very soon (being a beta-tester), but in this case I am still on 3.5. Simply because it is freezing over here and will continue and I don't need the car for a few days already. I am not going to sit in a freezing refrigerator. Tuesday I need the car. During driving I will update to 3.6. (Start the car, plug-in the usb-stick and it will start automatically).
A factory reset is not necessary. I haven' t done that for the last 8-10 firmwares (including intermediate betas).
If you have doubts, then simply go into settings and remove cache from the media app. If not working remove data from the media app. That is the one having the issues.
surfer63
Completely understand, it's also a bit cold here, but since I had to drive several times this week, I've updated to 3.6 already, also with USB stick. And I know factory reset is not necessary normally, I've also gone through updates to several firmwares and betas without reset. Only this time I was not sure because of not seeing any changes in AF function.
So, thanks for explaining, I'll try to clear media app cache/data, just to be sure. So the media app is the one responsiple for AF (and maybe other RDS functions) handling?
jamar This is exactly what I meant, as you write. The Mediatek Helio P65 has the best AF performance. Alternative stations are selected without errors, the radio can switch to a different frequency from time to time. In defense of the creators, the app was written from scratch, so it may have errors, from what I remember, the first AF application worked better there, but there was no steering wheel control.
Well, the thing is that RDS is not used in China, so It'd a bit hard for the developers to correctly implement something they don't use and can't correctly test in practice. I have also the experience with MTCD and Topway headunits and on none of them is the AF working correcly. And as you said, the Mediatek one being the only exception. So, let's hope that in the future the devs with the help from testers will make Dudu units the ones with best implemented FM RDS functions, maybe even better than those Mediatek ones You've mentioned ;-)
Hi all,
Is there any way to return back from bete 3.6 to 3.5 os.
I have some problem with 3.6os like miross app doesn't work,
keyboard on pip doesn't hide after finished typing.
Regards for help.

Omarmanaseet Please do not litter, if there is a problem look for it with a magnifying glass or describe a new problem.
I disabled airconditiner dashboard but still is popping up. Dudu6, Hyundai Tucson 3, canbus type XP.
Is any other way to prevent this? It is really annoying.
I want to suggest that some screenshots of the changes would have been awesome in the OP, they'll depict the changes better.
Dafior1 Settings-Vehicle-Canbus set-Floating AC panel. Disable it
Omarmanaseet Sorry for writing like that, I will check your problem, I did a factory reset, I wonder if I will also have this problem, just write what application
wybitny2
hi,
If you use PIP as main theme and yandex one of them, then when you try to search on yandex navigation the keyboard stick on the screen and never go away.
second problem there is an automation application names Meross for opening garage door with this update this application stop working because it uses the cloud and never connect to the cloud.
So if there any way to downgrade to the version 3,5, will appreciate it.
thanks for all of you,
Omarmanaseet Apparently you need an empty folder called lsec-downgrade . The software creators could publish how to do it exactly.
wybitny2 what do you mean about software creators?
Omarmanaseet I think what @wybitny2 is trying to say with software creators is the developers. The best way to get help is to get on telegram channels. Please choose your thread carefully.
MihaiFlorin Yes, it was about the developers, sorry, I expressed myself incorrectly.
Ok
Thank you so much
Can anyone send me the link of telegram channel please?
Im new here in this world of dudu7
Thank you to everyone
jamar Purtroppo la funzione AF non funziona, praticamente la radio FM non si può usare, non capisco perché si impegnino su tante applicazioni ma sul sistema AF viene messo da parte. Vorrei ricordare agli ingegneri che la parte più importante è la parte radio FM , perché si ascolta sempre quando si viaggia in auto. Scusa se ho condiviso il tuo messaggio però non capisco perché non si impegnino sulla parte più importante !!! " radio FM"
Omarmanaseet Or maybe you need to be patient, the developers will come back after the holidays and improve dudu 3.6

Pietro My friend I am not taking any sides here. Maybe for you the most important part is the radio. For example I don't listen to radio at all I prefer music streaming (YT Music) because there are no commercials (on YT premium). You must understand one simple thing. In China RDS system simply doesn't exist and it is very hard to test and so on. If you'll say that the AF function is not related to RDS I will contradict you. And believe me when I say the devs are working on it. But it is similar to try to make surgery blindfolded. It is very easy to speak bad things, but you must understand that the developing team had a holiday in this period.
MihaiFlorin It's true, the application was written from scratch, that's why it has problems, and it develops nicely. I prefer FM radio anyway, in Europe most people listen to FM radio.
MihaiFlorin Sapere che ci stanno lavorando è già una notizia importante, però non sto dicendo cose cattive, sto solamente facendo una critica che penso sia costruttiva! Poi avevo fatto questa osservazione sul sistema AF perché è vero che in Cina non esiste RDS , però questi apparecchi android vengono venduti in tutto il mondo e credo che il problema si ponga anche in altri stati, detto questo aspetterò con pazienza qualche miglioramento AF , grazie per la risposta e a presto ciao
Добрый день. Вы бы сделали в своих прошивках чтобы видеорегистратор с адас при оповещении обопасностях не выключал звук штатного музыкального плеера.
trap63 L'ho già usata, ma non cambia nulla, comunque ho capito che in Cina non c'è RDS e va bene, in Europa RDS c'è e se viaggi in macchina se vuoi ascoltare la radio FM è meglio che la spegni perché dopo qualche chilometro senti solo un fruscio, la stazione non riesce a più a trovare. È vero che ci sono tante applicazioni musicali,ma io avevo acquistato il dudu con la speranza che avevano migliorato RDS, ma aimé è peggiorata rispetto al Dudu 7862 che forse qualche volta riusciva a cambiare. In conclusione ho capito che queste meravigliose radio fanno tantissime cose ma la la parte radio FM è veramente deludente.Vi ricordo che se si riuscisse a fare funzionare RDS in Europa, sicuramente le vendite aumenterebbe di molto.
MihaiFlorin . I did it - not works :-(

NavRadio is of course great, I use it myself, but Kotix uses for his software the same radio functions from firmware as the built-in media app. So he cannot control the RDS functions, onle enable/disable it, as the implementation is handled by firmware. That said, RDS AF with NavRadio works exactly the same as with builtin Radio app...
