Kind request from users:
Please report any kind of new issues you experience after installing this update only if you've already flashed this ROM with SP Flash Tool in Firmware Upgrade mode. In rare cases a FOTA update can cause more or less serious malfunctions but that means only the update process went wrong, not a badly developed ROM. An updated stock ROM, especially related to the basic functions will not cause any new issues but will solve some of the existing ones.

ROM: >>>>> coming soon... <<<<<

When to wait for firmware?

"Coming soon" means "coming late" or "coming never" ???

Quando vão fazer uma atualização para o Umidigi A3 ????

FR8146

Umidigi specifications for this phone say "OTG enabled".
In reality I don't get OTG working. When I connect one pen drive to usb port with an apropriate cable, the phone has no reaction at all. Not the slightiest signal of such connection.
Is it a matter of settings? Wich ones? Or the phone is not really OTG enabled, like Umidigi says?
Has anybody got this working?
Thanks

Boa tarde, UMIDIGI A3 ficou com tela preta da morte após a atualização da ROM

Marcachas

Good afternoon, I have the UMIDIGI a3 phone (version with android 9 from the factory).

This phone has given me huge headaches, since it was a gift for my mother and the poor thing has had problem after problem after problem, I always try to solve them, but this time, it has made me mad, my question is the following:

With the latest firmware version AND ALL THE EXISTING ones, (except for 1.0, that doesn't even allow me to use the touch screen), after a time of use, be it 2 or 3 days, it starts to freeze for no reason, you can writing, watching a video, or playing a game that is to your liking, whatever the situation, freezes.

I have already tried everything, disable all applications, disable background services, disable services, update the firmware with the download option, with the upgrade option, WITH ALL, after a few days, it kept freezing continuously, and continues, and continues, and continues ... Always the same, so try the last resort, format everything, often error.

Now it doesn't even allow me to use it, I always get a black screen randomly and after half an hour, it tells me that there is an error with google services.

Investigating, I see that it is the problem with the fingerprint reader, which I understand, BUT THEY DIDN'T LET ME ANY OPTION, I am fed up with this terminal, so I ask the following:

1.- Since my problem first occurred within the warranty, I demand a solution to the problem of random freezes that this terminal has (Umidigi A3, Android 9 version).

2.- Since my despair, I format everything completely and now it does not even allow me to use it, I know that there is an option to pay, but it does not seem right since I mentioned the above.

I hope you can tell me a solution, please, to any of the 2 points, by this means or by my email, marcachasgro@gmail.com
