"Why does my BLU vivo XL2 keep exiting applications?"に関する回答I have 2 of these phones in my family and noticed the problem occurs especially whenever the charger is inserted. Solution I think is to replace the USB charging connector. I am currently searching online for a replacement part and will update if I found it and do the replacement. Update (05/31/2019): I have tow of this phone in my family and noticed the problem is amplified when the phone is being charged and handled. I think there is a defective charging port that needs replacement. I am now searching online foe a replacement part. If anyone fine a supplier, please post website address. I will followup if I am successful.
