  1. Hi I bought a Samsung A12 in Feb.

    On the 5th March it starting beeping for no reason at 19:00 hrs.
    I had to turn it on/off to stop it.
    It shows nothing to indicate why it’s going off.
    I tried all recommendations to rectify it, but it kept going off everyday at the same time.
    On the 13th March I put it back to factory settings.

    It stopped happening, until today the 5th April at 19:00, when it starting beeping again.

    Why is this and how do I stop it?

    • Thank you for your valuable comment.

      Your first problem solution:

      The music player on recent Samsung Galaxy smartphones has been merged into Google Play Music, so your Samsung A12 does not have a Samsung Music Player app.

      Your fourth problem solution:

      To solve this problem, first go to Google Play Store

      • Then click on your profile icon in the right side.
      • Now click on Settings
      • Then tap on General Settings
      • Just select the “don’t auto-update apps” option
      • That’s It

  34. I just got Samsung A12 recently , everything works fine but there is a problem, when i have my phone in my hand i can click and scroll easily but when i put it on the ground i can’t click or scroll the top part of the screen

  35. Hi there, my problem with my A12 is that it either doesn’t ring when someone calls, or the other person can’t hear me or my voice is breaking up. I have checked volume and it isn’t that. If I move to the front steps of my apt there is sometimes an improvement. It is so frustrating! It comes and goes…. are there “dead spots”? My older J1 worked fine with calls… in the same location. I hope you can help.

  36. Hello! I recently got my A12 and I can’t find a setting that makes the phone flash a little light indication when I get an sms or other message, or there is no such on this phone?
    Thank you.

  37. Bought A12 recently. Length of time it rings is not long enough. Sometimes it it about 4 seconds, others 15 seconds and others 12 seconds. Tried **61*121*11*30# to change to 30 seconds but still the same Samsung said to try **61*321*11*30 but again still the same. Any ideas how to change permanently.

  38. The app that keeps closing is the settings app. I am unable to clear the cache as the app closes before I can get that far. I can’t work out how to solve this.

  39. Hello,
    I bought my phone Samsung A12 two months ago,it’s cut off on the middle of my conversation.

  40. Hi
    I bought this phone in August 2021 , and it seemed to work fine. But recently whenever I try to send voice notes ( whatsapp, telegram, signal) it doesn’t seem to work. Sometimes you cannot hear the audio, or in the middle it just gets cut off. I thought there might be an issue with the apps itself, but for others it seems just fine. Please help. Thank you.

  41. just bought my son the a12 for xmas and got it all setup but the wifi range is absolutely rubbish, it will only connect to wifi if phone is right next to router.
    i have tried everything from clearing the cache partition, resetting network and factory reset but the range is still rubbish so now im thinking possible software issue or phone is broke?
    i have tried everything i know and googled and youtubed and still no wifi range, but every other device is working perfectly with wifi.
    am i missing something or does phone need to go back for repair/replacement
