[FYT Android Head Units] yegolebi:
First, let me list the good stuff:

- The sound is very good, better than I expected.

- 4G, Wifi, GPS, OBD2 work very well.

- The screen is high quality.

- FM radio receives well.

- All the apps I usually use work well.

- It looks like third party launchers are working even though joying says they are not. I use CarWebGuru.

And now the bad part.

I have chosen a high resolution version (1920x1200) and it looks like this was a mistake.This is a relatively new and rare version, I rather don't expect fast and frequent updates.

The lower resolution Joying units already have a new interface and maybe some other improvements as well.

I have the following problems:

- The fonts and all elements in third party apps are absurdly small. It is impossible to use it as is, and there are no display size or font size settings available. I managed to force DPI change through developer options. After the change everything looks good, but built-in launcher stopped working (problem solved by installing carwebguru - which I would have done anyway) also sound settings app doesn't scale well and can't be used (problem not solved, to change sound settings I have to restore original DPI, I tried to use tasker but it didn't work) I think this problem only affects high resolution units

- It is impossible to disable the reversing camera while retaining the rear parking sensors functions. I don't have a reversing camera so if I put reverse I see a black screen and a small graphic of the car with sensors on the right. The reversing camera can be disabled by cutting one of the wires in the harness, but then the sensors graphics are not displayed either. This is frustrating because the sensors are working, as you can see on the graphic, which is displayed when the front sensors are triggered (this is nice, big, overlayed graphic) . The rear sensors, however, do not cause this graphic to appear (although their signal is displayed when both front and rear sensors are triggered at the same time). Looks like it would be easy to fix, but I' m not holding my breath....

- Since the unit has no buttons I wanted to use a navigation bar type app (simple bar with home, back, recent buttons). Navigation bar works great and is very useful but it is deactivated every time the unit goes to sleep.

- I installed the update for wireless android auto. Android auto works wirelessly now, but after the update I lost the split screen function, and everything is too big - I think this update is not designed for my resolution. I got the files from Joying support. However this is not a big problem because as it turned out I prefer to use android unit than android auto. Apparently they are working on a solution to the problem.

- I use a remote controler from the Joying website based on resistance detection (I don't have steering wheel buttons). Remote controler works well, however there is no possibility to program ‘back’ and ‘recent’ button functions (it would be very useful) - home button function is there and works fine.

-The problem of deleting google contacts has not happened to me. I have a second google account set up in the unit, into which I imported contacts from my main account.

However, the problem is the Bluetooth phone app. It is possible to receive calls without any problem (the caller id is displayed correctly), but initiating a call is impossible because the contact list in the application is empty, call history is empty, I was not able to create a list of favorite contacts (just a few would suffice). To make a call I would have to enter the number manually. I managed to solve this problem by installing dialer application, which sees my contacts and call initiated by this application is made via bluetooth phone.

It may sound strange after this list, however, I am happy with this unit. Especially because of the sound quality. I've gotten used to the problems listed above and I'm not going to waste any more time fighting them.
