Huawei TAGAL00(Enjoy5s) Contact name not recognisez on caller screen but shows number

Hi I have purchased a "Huawei Enjoy5s" in China.

MODEL NUMBER: HUAWEI TAG-AL00
BUILD NUMBER: TAG-AL00C00B124
ANDROID 5.1 KERNEL: 3.10.65
EMOTION UI VERSION: 3.1 LITE

The phone was running fine on 'chinese sim card'.
But I moved to a new country, I use a 'local sim card' i.e. a sim card from a carrier in the new country.

I have noticed that when I use the 'local sim card', the phone does not show the name of local contacts during incoming calls.
Instead it shows
1.Number of the contact: xxxx-xxxx (please note, the number is a local number and is displayed without the 'country code'.)
2.contact name: unknown. (please note, in my phone book, the contact has the number stored with the country code ie +230xxxx-xxxx)
3.Name of the district the call is from or 'Mobile' in case of call from mobiles.

I have tried to remove the country code in the phonebook and the contact name appears on the incoming call screen. But then the contact name disappears from SMS in messaging screen and shows number only. (note that the sms shows number with country code ie +230xxxx-xxxx).

Please note that in the phone book, when you select the contact, all call history for that contact are recognised irrespective of being with or without country code.
BUT under the call history of the dialer, the numbers are not recognised unless the contact has the number stored with the country code.


I believe
the phone app is unable to match the number to that stored under contacts unless it is exactly the same ie without country code
V/S
the messaging app that is unable to match the number to that stored under contacts unless it is with the country code.


Is there a patch or variable to change in system file to fix this?

I have cleared data from (2 phone apps being a dual sim, contacts phonebook, contacts storage, phone/messaging storage) and reloaded my contacts from vcf file or from google account but still no success.
-

I have tried to look for alternative apps to replace the "phone/dialer/incoming-caller-screen" app but again this is not possible due to huawei launcher.
-

I have also been able to install google play services framework and gapps successfully but it did not solve the number-contacts problem.
-
I have even tried edit build.prop under system with build.prop editor and saved, reboot, cleared data, resyn, but no success. I modified only "ro.config.hwft_MatchNum=11" to "=7" as my skill are limited. (I have read you can modify boot.img 's build.prop file but I dont know if it will work and have not tried it and dont know how to do it.)
-

I then updated the firmware to BUILD NUMBER: TAG-AL00C00B156 but no success for the problem.
Now I am back to firmware BUILD NUMBER: TAG-AL00C00B124.

Is there a patch or variable to change in system file to fix this?
Can anyone tell me how to decompile, edit and recompile system file like telephony or others that will solve matter?
