Umidigi S2 V1.0-20171027 Launcher 3 not run

Pitty

THIS IS IMPORTANT:  After update Firmware to Version UMIDIGI-S2-V1.0-20171027 Launcher 3 will not run. After restart the phone every time Launcher 3 was finished,  okay,  and the same happens again. The phone cannot be used. PLEASE DONT INSTALL THIS UPDATE.
@UMIDIGI:  Please fix that immediantly!

UPDATE: When you have installed this OTA Update UMIDIGI_S2_V1.0_20171027 and your Launcher 3 will not run, you can do this steps:
1. start the browser (chrome) this is only possible in the same second when you quit the Launcher error (~1 second)
2. type "Play store" in the browser address row, now you see the results of Play Store search
3. klick on Play Store App - the Play Store open out of the browser (use never the back button on the phone)
4. search for Launcher (I have used the Apex Launcher) install the Launcher and open it from the Play Store App
5. Make the new Launcher for your favorite Launcher (disable Launcher3 from Umi)
6. Now you must make a complete setup for the new Launcher - but Apex Launcher runs fine.
--> done, you can operate with your S2 phone....
But a bugfix from UMIDIGI is needed...
