Data problems on Lenovo Z5 after android upgrade

Yesterday, I upgraded my Lenovo Z5 to the ZUI version 10.5.248 ST (Andriod version 9) Since then I cannot get data through the SIM card. I have changed the APN settings to the correct GiffGaff ones (my service provider). I have saved them and selected them properly - data is switched on. Correcy SIM is selected. It is very frustrating. Can anyone help please? Thankyou for reading.

Hi Alan10eden,

 

Thanks for posting. Are you seeing the arrow beside the mobile signal icon on the status bar? Have you tried testing another SIM?

 

Best regards,

No - there are no arrows beside the mobile signal. I can however see the symbol 3g or 4g - depending on the coverage in the area. The phone is working fine on wifi. DO you have and idea what settings I need to change to allow data to return to normal?

I have tried a different sim card and it does not give any data either.

Hi Alan10eden,

 

Thanks for trying. Can you please check if you have an option to reset the network settings (Settings > Reset > Reset Network Settings). Also, have you tried booting in safe mode?

 

To Enable Safe Mode
1. Press and hold the Power button until Power off comes up on the screen.
2. Touch and HOLD Power off on the screen until reboot to safe mode appears.

Best regards,

Re: Data problems on Lenovo Z5 after android upgrade

I have updated my phone to the latest software and I have no 3g connectivity since then too.

Cannot delete/reset the settings and I can see it is rying to connect through China telecom.

This is SO FRUSTRATING...

I regret for downloading it and I still haven't seen any fixes.

Re: Data problems on Lenovo Z5 after android upgrade

Hi Everyone,

 

We don't support Lenovo Z5 as it's not intended for sale in Europe. The device is for sale in China - Lenovo.com.cn. We recommend posting in Lenovo Forums in China for further assistance. Here's the link

Re: Data problems on Lenovo Z5 after android upgrade

I don't understand why Lenovo China selling Z5 outside Chine if the phone was intended to sale only in China? 
Now users of Z5 all over the World are dismayed...
