Missing or surplus Incoming character

(Hamidreza Mahmoudi) #1

Sometimes I receive Incoming SMS with Missing or surplus character from previews SMS in UTF-8 Messages.
Sometimes several characters from the previous SMSs with the new SMS are added to the end of the sentence.
What can I do to fix it?
which logs I must leave here ?

Green is Original Messages and Yellow is surplus words from previous SMS
