I have issue before my screen black .I connect with charger its sound but my screen black.
About 1 week 3 day .I try the option volume down power button its on .Then i hard reset now its ok and then download apps back and then clear cache partition.
◇[NOTED😘 ::MY PHONE IS OK JUST SHARE MY EXPERIENCE SORRY MISUNDERSTANDING😅]◇
1 .Maybe cause software update because patch Jun or July i not remember i cannot clear cache partition anymore.
2.My screen its ok not have crack at all.
3. Maybe im always charge at all time 80% it can cause black screen sometime i charge when i sleep i didnt turn off the charge.
4. Once per month i didnt use until 0% and then charge with switch off the phone until full.(not recommended😅 better just clear cache partition or restart).Better research at youtube😚 how to maintain good health battery.
THANKS FOR THE TIP IF YOU GUYS HAD🥰 EXPERIENCE LIKE ME YOU CAN REFER COMMENT BELOW OR YOU CAN SEARCH YOUTUBE HOW TO FIX BLACK SCREEN IT OR GO TO SAMSUNG SERVICE CENTRE IF NOT FIX😉
It is auto maintenance health because the phone model as can access to virtual service center ,don't worry just go to device care. I will show the step to enable and check the device health.
