[Xiaomi Redmi Note 4 Questions & Answers] android.flasher0517:
I mainly use my phone to send long messages (SMS around 4,800 characters long (30 messages)) to my colleagues. Unfortunately, my Redmi Note 4x only allow up to 8 messages long before converting the SMS to MMS.

Using 3rd party app allows to send these messages without converting to MMS. But I don't want to use other apps as this consume resources.

Decompiling and editing string on mms_config.xml of the Mms.aok cannot be done as there are errors shown when I tried to recompile it.

This is the error:

warning: string 'chenghu_disable_mms' has no default translation.

warning: string 'mx_activate_notice' has no default translation.

warning: string 'pref_summary_show_recent_contacts' has no default translation.

warning: string 'pref_time_auto_group_disabled_summary' has no default translation.
