How i can ability for double tap to wake

    Arun, 02 Oct 2020Phone is flickering while charging and discharging and also... moreUse original charger and cable, if still under warranty send it in, if not, take to samsung store and get them to try charging the phone to see if issue persists, if not then your charger is crap, if it does flicker then your phone has a hardware issue. Before sending it in, do the following;

    1. Delete cache, especially battery app cache.
    2. Switch off.
    3. Boot into recovery mode, either by pressing volume down and power button for 15 seconds or until phone boots, once it boots into recovery, delete davlik cache. Reboot as normal.
    4. Now try charging it if you are sure you have original good working Samsung cable and charger.
    5. If still flickering, then time to do a factory reset by going as so
    5.1 Back all personal data to sd card.
    5.2. Go to your playstore account and set updates to manual, if any updates are busy downloading from playstore, let them finish. Then set updates to manual.
    5.3 Clear all app cache.
    5.4 Now switch off.
    5.5 Boot into recovery mode and do a factory reset, NOTE: ALL DATA WILL BE LOST. So back data as i said to sd card first.
    5.6 Factory resent when finished will restore the phone as it was when it was taken out brand new from the box. The phone should reboot automatically when finished or may ask to reboot, if so , reboot.
    5.7 At this moment dont setup the google account, just skip, if phone detects OS updates and other firmware updates, let it update and boot up without your activating google account.
    5.8 Now try hooking up the phone to charger and if it flickers. If still does, go manually to settings menus and to go "about phone" and double check if any updates are needed.
    5.9 During these the phone may detect it needs more updates, download and let them install.
    6.0 At this point if you noticed you had updates from Samsung and also Android security patch upgrade, then you want factory reset the phone once again.
    6.1 After resetting AGAIN to factory settings, whatever SAMSUNG OS UPDATES and ANDROID SECURITY patches that previously installed wont be removed.
    6.2 When boots up now you can setup your phone as normal as when you took it out of the box, setting up email and google accounts, wifi etc.
    6.3 Now test again charging flicker issue. It may have been resolved, but put the phone on areoplane mode if charging is back to normal and let the phone charge to 90%, then disconnect charger, turn off aeroplane mode and now open google playstore and let all apps update, but if you notice google play service requires update it, then reboot and now let google playstore update other apps. And while it doing so do not use phone, once all its completed, then clear cache and davlik cache in recovery mode, and reboot and see if playstore has any more updates. Once certain your phone is properly updated, just connect charger to see if still flickering, if no flickering then some firmware updates was corrupted on the phone.

                                    lol i had no complaints at first because display and performance was equal to price range but can anyone explain why the right side (screen facing towards user) around the volume and power button is creaking, at first i though it was my case (bcoz im using armored case) then i realized it was all rubber except for the back so when i inspected my phone i heard that the creaking sound came from there. does anybody know why it's doing that and if it's a serious problem?
