UMIDIGI Z1 V1.1_20170726 ROM - SPFT + OTA release

bencebacsi

This is the SP Flash Tool + OTA release of the

V1.1_20170726 system software

for UMIDIGI Z1

Flash tool operation is recommended for experienced users only. Do not use it if you cannot understand the whole process!

UMIDIGI Z1 receives all updates automatically via FOTA method. You need this tool only in case of emergency (if you've bricked your phone), if you want to apply a clean install or if you want to clear all root access and custom recovery to make your phone able to receive FOTA updates again. Another reason can be if you experience unexpected issues after updating via FOTA.

Changelog:

• Optimized camera interface
• Optimized camera PDAF focus
• Displaying MEID removed

You need a microSD card (with at least 4GB capacity) installed in your phone!

• Copy the ...update.zip file to your SD card
• Press and hold the volume-up and power buttons together until your phone restarts in recovery mode. It needs about 10 seconds or a little bit less if your phone was already powered off.

• After a succcessful installation you can read the ''Install from sdcard complete'' message and the receovery menu is available again.
• Select 'Reboot system now'. Alternatively you can perform a factory data reset here by choosing 'Wipe data/factory reset'
  

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.

I am running this version but am seeing several issues:
- reboots while the phone is lying around doing nothing. This means I can not be called anymore as the telephone part is waiting for the SIM card PIN code
- freezing wifi on AP switch.

when is a new verion of the firmware expected?

After updating, activating the option to change display color, the display after a few seconds becomes white and does not see anything. It does not solve even restart. Must be reported to factory data. Solutions?
Thank You

Hi,
Normally there are no such issues with this version. Have you flashed your phone with SP Flash Tool?
Updates are frequently released for a while but they are not scheduled.

Hi
There is a problem with most online voice messengers. When caller is apeaking he hears his voice with some delay, there is the echo. The echo sound is very clear and loud. The programs are Viber, Telegram. Other messengers wich can work smartly with echo cancellation algorithms are trying to kill this echo but sometimes it is also present. For example Whatsapp, Skype. It seems that there is a problem with program mixer which routes sound from speaker to mic path for these programs. Please note that there is no any acoustic feedback. The mic cannot hear speaker, checked also with headset.
It is first time I encountered with such problem, my previous phone Umi Max has no this issue. Now all my callers are complining that they cannot speak with me due to echo. Please note that GSM is working perfectly. There is no any echo effect during an ordinary call.
