PAUSE, 12 Aug 2019i have restarted my pdone and after that i cant swicth it on if there is guarantee plz take it to the store where u purchased it. Something is wrong with ur phone, cuz after that simple action of reset, don't have to be any problem
sometimes upgrading or updating make the phone not to work properly. in that case i perform factory reset
honestly, i think that, if my phone works good as it, i don't need any upgrading. All the time i click on Later
I had this phone for only 5 months , and without any reason my microphone stopped working it's a decent phone for the price but this microphone problem is a big problem , not only my phone but my two friends had this problem on their j3 and j3 pro and the same, it happened without any reason , i advice you to stay away from the J series since this microphone problem happened to a lot of people

Changing the phone's name (optional) & the phone's network name (optional):
Changing the phone's name:
go to SETTINGS > ABOUT PHONE > you'll see the phone's name and, if there is below the name option EDIT, click on EDIT: delete the phone's name & enters yours
Changing the phone's network name:
* Turn on MOBILE HOTSPOT & TETHERING

* a dialog box: ALLOWED DEVICES > CONFIGURE MOBILE HOTSPOT = click on this
* on NETWORK NAME, delete the one given and write yours
* (optional) on PASSWORD, delete the one given and write yours
KNOWING THE SAMSUNG A10 & J4
You can avoid touching the physical buttons:
SETTINGS > Accessibility > Interaction & dexterity > turn on the "ASSISTANT MENU" (a circle with 4 dots pops up at the right side of the screen) = there is (among others) a button for:
* SCREENSHOT --instead of pressing "vol. down & power"--.
* SCREEN OFF ("LOCK" ; "LOCK SCREEN")
* on "phone options" = SHUT DOWN (POWER OFF); RESTART; EMERGENCY MODE --instead of press power button--.
* on "menu settings" button = TURN OFF ASSISTANT MENU --instead of press power & vol. up physical buttons--. You can turn on ASSISTANT MENU before SCREEN OFF, quickly: just go to "RECENTS"
# Download app for wake screen & you avoid touching all physical buttons
# It's possible to attach DOKs because this phone features DOK otg, so you can download data to a DOK
# It works on J4 too

Rizi, 06 May 2019Very nice experience.... little bit speed slow but everything is perfect. Specially Night modeYeah but to me I am not comfortable with the Pie on J4 I pan to roll back to android Oreo.
bought my Samsung Galaxy 4 in Nairobi at a reliable store. Cannot find a sim card that registers so I can use it stateside--any help/suggestions so I can get it to work?
Sam, 23 May 2019My phone restars automatically when i play games...does anyone have a solution for this??There are 2 solutions for this:
The J4 has released a new update this year (2019) to solve this bug... I suggest you update your device to latest Oreo.
If for some reason you cannot detect a recent update then there is another solution. Go onto Apps
Delete the "Game Optimizing Service" -- This has been causing the instability of playing games...
Hope this helps..
