UMIDIGI Z2 Pro security bug and update plan

Post time 2018-9-11 10:37:50 | Show all posts |Read mode
Hi, dear UMIDIGI fans,

We received feedback from real users that after rebooting on the UMIDIGI Z2 Pro screen lock becomes invalid. We sincerely apologize for any inconvenience due to the security problem.

At this moment our engineers already have solutions to this problem. The new update is planned to push out in this week.  

Before the problem is fixed, to use your phone, you need to boot into recovery to perform a factory data reset. To do so, please follow the instructions below.
1. Press and hold the volume-up and power buttons together until your phone restarts. It needs about 10 seconds or a little bit less.
2. When your phone is restarted, immediately release the power button but still hold the vol-up button until you see a lying android figure with an exclamation mark in red triangle on its tummy and ‘No command’.
3. Press and hold the power and vol-up buttons (in this order) together, then release them to call the recovery menu. Now you can move with the volume buttons and select an item with the power button.
4. Move to ‘Wipe data/factory reset’ and select it.
5. On the next screen move down to 'Yes...' and select it. Now your phone will be reset to its factory settings.
6. On the next screen press the power button again to reboot your phone

Also, another new update for improving camera performance is also planned in the next two weeks, we will expect a more professional bokeh effect on the UMIDIGI Z2 Pro soon in the future update. Please wait for more updates patiently.

Yours sincerely,Yan

Update: 2018.09.20

Dear UMIDIGI Fans, due to some circumstances, unfortunately, the update is delayed. Thank you for being patient. Just to let u know,  the new update for UMIDIGI Z2 Pro is planned in this week(before 23rd Sept), the new OTA update will fix the problem with PIN code and pattern invalid problem. A more professional bokeh effect on the UMIDIGI Z2 Pro is planned in the next week.  Problems occur and that's the part of everything. But we regret the inconvenience caused.

Notice, If you press the power & vol-up combination and your Z2 Pro always boots into the Chinese language factory mode, please press again power & vol-up when in the Chinese language factory mode to restart and next time the phone will boot into right recovery mode.

Many thanks for your patient.

Yours sincerely,
Yan

Hello Umidigi,
Are You going to fix proximity sensor problem?
When you plan to prepare new OTA?

We didn't experience any of proximity sensor faults.
Please flash your phone with SPFT and test, if you still have same issues then probably you have hardware issues and you should contact to seller for warranty solution.
Also you can check with one of first softwares and calibrate from settings - display -

Well, Thursday has come and gone, now Friday with no news of the planned update.

UMIDigi ADMIN, please provide an update for all users so that expectations can be set. Also notify your distribution channels of this issue, they should be aware of this issue and be prompted to notify users and new Z2 pro owners of the issues and the time frames for resolution.

I assume that there will be detailed release notes so that we, as a community, are all aware of what aspects are being dealt with for each new release? There are many users experiencing common issues, but also some experiencing different ones, so clarity is requested.

lo he hecho varias veces y persiste cuando esta en 4G no me entran las llamadas

Buenas,
Lamento que no te funcione, me imagino que si la sim funciona bien en un terminal diferente y has provado las diferentes configuraciones tendra que ser el terminal en si.
Saludos

You should also add rest of explanation.
We contacted to MTK about 4K recording and MTK is investi ...

When do you expect an answer from MTK?  If everything is fine, and you received the 4K driver, when can we expect an update patch to support 4K video recording??

When will gesture support come to  Z2 Pro?
Without it, the phone really doesn't feel user friendly.
...

Why don't you install an alternative launcher like Nova Launcher? It supports gesture and it's loaded with a lot of other interesting features. I ALWAYS install Nova Launcher on all my phones since it's beginning. One of the first few things I do.

Are your able to make calls over VoLTE?

VoLTE is working without any issues on networks which are compatible with phone. When you make or receive VoLTE call you will see "HD" short on screen.

Please solve the problem that you can not connect to VoLTE.
The product is sold as a 4G4G DSDV, but it is not DSDV because VoLTE can not be used.
Does the global VoLTE IMS information drop out in the definition of MBN?

If you are updating the camera application, please remember to memorize the shooting mode at the time of last time, to set the default of the shooting mode to automatic, to make the shutter sound "disappear" properly.
Thank you. Please do your best.

Thank-you for the update. I can confirm the reboot sequence works fine.

Note to people trying this: If you get the timing wrong, you'll end up with the Chinese menu. Just scroll down and select the bottom entry (which is reboot), then switch off and try again.

Proximity sensor could not be calibrated. Abrupt stops, blank screen when playing youtube (if your hand happens to block the proximity sensor). And adaptive display is not working or insufficient to detect the amount of light.
