Samsung Galaxy A5 and A3 (2017): here are all known problems and solutions

Technology has its issues. Like all devices, the Galaxy A3 (2017) and A5 (2017) have their share of problems that can sometimes spoil the experience a little. Of course, these devices aren't exploding like the Note 7, but there are some are minor problems which happen to some users. Fortunately, we have the solutions for you here.

The battery drains very quickly

Problem

Several users have reported the following problem on the Galaxy A3 (2017) and A5 (2017): the battery empties in just a few hours. The strength of the A5 being its battery life, it's all the more irritating.

Solution

If the loss of battery life seems really drastic, your phone likely has a defect - because the battery life of the A5 (2017) is well above the average. The A3 (2017) isn't bad either. It normally allows you a full day of use, including social networking, surfing, video and more. But, if you only get a few hours out of it, you've got a problem.

Go into the battery settings to see which applications are consuming the most energy to find the culprit. Some applications can work in the background, and, if they are poorly optimized they can seriously drain your battery.

The fingerprint reader doesn't recognize your fingerprints

Problem

Some fingerprint scanner are quite finicky, but it is difficult to make a generality because several factors come into play: the way you registered your fingerprints, the condition of the finger, and so on. Several users have complained about the fingerprint scanner of the Galaxy A5 (2017), especially my colleague Jessica who had noted a big problem with it in her review.

Solution

In most cases, the problem comes from the user: make sure you have registered the fingerprint from various angles, in the same position as when you try to unlock your phone. This seems silly, but many users simply put their finger on the scanner during configuration, without swiping it correctly. Also, remember to keep your finger dry.

It seems from reports that the A5 (2017) is more affected than the A3 (2017). That said, it is still possible (in theory) that Samsung could offer some kind of an update to fix the problem.

The device does not connect to the computer

Problem

Normally, your computer detects your Galaxy A3 (2017) or A5 (2017) phone when you connect it using a USB cable. But, sometimes the phone is not recognized by your computer.

Solution

First of all, you need to use a quality cable (either from the manufacturer or another reliable brand). If you don't see anything on the screen when you connect the phone, don't panic. Look at your phone: maybe it has detected the connection is prompting you about what to do next. If you still do not get any response from the device, check out the developer options (see how to enable them in this article) and enable USB debugging.

The WiFi connection is unstable

Problem

You are connected to the Internet with your Galaxy A3 or A5, and all of a sudden the connection is interrupted. This problem occurs from time to time (and not just on this model). It's difficult to determine the exact origin of the problem with this one.

Solution

Samsung has not communicated anything official about this problem, at least for now. This kind of issue is difficult to diagnose as there are several factors that can cause it. If you are sure that the problem is with the device and not with the connection (which is rather unlikely), check your network configuration and update your apps. Keeping your apps up-to-date to ensures their stability. If the problem persists, leave us a comment.

The touch screen is unresponsive

Problem

The touch screen of the phone leaves something to be desired, and sometimes you get no response from it at all. Navigation is complicated on the Galaxy A3 (2017) or A5 (2017) and sending messages seems to be an impossible mission.

Solution

The problem can be with the device hardware: if you have just received your phone, then it may have a defect, and if it has been dropped, that's another very likely cause of the trouble. It's difficult to do much yourself in this case, so get it repaired.

If the problem is software, simply restarting your phone may be the fix (it worked for me, in any case). If you are a more advanced user, you can try installing another ROM to see if this fixes the problem, but be sure you won't void the warranty first!

  • Hi, I have the samsung galaxy a5 2017 version the past month or 2 sending & receiving texts has been a hit or miss process. Now the last few days when anyone calls me they tell me my phine echoes. I don't hear it but, they can hear themselves talking.
    Any idea how to resolve these 2 issues?


  • Hi i am using samsung A5 7..this phone whatsapp and imo any using app send voice message not send 3 seceand Above...what soliusiion iits problam


  • messenger does not work correctly. Flashes when trying to make a video call and cannot accept any video calls and screen just continues to flash. Tried re-installing messenger but that did not work. anyone else experiencing this problem?


  • My A5 2017 needs to have its proximity sensor recalibrated almost every day. Any suggestions on how to fix this?


    • After the Android 7 Nougat update? With Android 6 the proximity works correctly. I have no fix at the moment


      • Yes, it was with Android 7, but there was a Samsung update recently and I had not to recalibrate for a while since then. If anything changes I'll comment here and update.


      • I have tried the firmware update and the problem still persists. I had to roll back to Android 6 to get rid of it again.


      • Hey Paul, I just tested my sensor and it is not working again. If it works rolling back to an older version of Android it probably means that this problem is not related to a Samsung firmware failure, but rather to some incompatibility between the newer android and that firmware. Perhaps we should try and report this issue and information to both Samsung and Google


      • I believe that it's Samsung's issue and they are not aware of the problem with Nougat.


  • Have A5 2017 and have problem with wifi signal. Maybe know why. If i lput my second hand on top of phone (viewing internet, watching youtube, playing games etc.) and hold phone with both my hands, the signal is almost imidiately much more worst, sometimes lost. Whe i get hand out, its return to strong signal of wifi. Its really bad and problém with construction. Maybe its only my phone, dont try another one.

    i have A5 (2017) over 2 months and sometimes it just turn of and i noticing it when i need to use it and screen is black. Few times pushing all buttons and nothing. Sometimes i feel short vibration when i hold 'turn on' button for few seconds. In the end i hold 'volume down' and 'turn on' buttons for 8-10 sec and it tun on. And today was odd situation, somebody calls me and i take phone and screen is black and cant turn it on, but ring tone is working...


    • bro i have same problem


      • cree 5 months ago Link to comment

        Also i had problems with charging and battery lasted just 1 day with medium power saving, after night 10-20% off, but now after few Android updates, everything works prefect. I don't need to charge battery every day even when i play online games, and don't turn it off by it self.


  • Look +-5 comments down, there is my comment with urgent problem.


  • I have got screen flashing problem, specially when puting brightness to low, it flashes a purple color. also screen wont turn on sometimes and i try to turn it up for few minutes by pressing power button many many times and that is really annoying.

      I had your problem with my galaxy J7 . It was really annoying.whenever I turned the screen off or put the brightness to low it flashed some lighting from the screen .

    My Samsung A5 had this weird problem of ghost touch at first at the bottom of my screen. It was then followed by the phone screen being unresponsive at the bottom of the screen (around 2cm high) and before i could get it to service centre, the whole screen turned unresponsive! Hopefully I can get it fixed...


  • My A3 screen has decided to stop working. Samsung won't repair it claiming there is a crack in the screen, invisible to myself or the Three store reps. Three won't give me a replacement even though it's still under contract & warranty. Where do I stand?


    • My mum's A3 screen too! Respectively, when she plugged on the mobile and she just received a message (SMS) it SHUT DOWN. When you try to turn the phone on, the first thing appears is 'Downloading' on the green BG & in the left upper corner there are lines about informations about battery, software and things like that, this text is pretty tiny & it is pretty colourful differenting.
      The farest point on the way to turning it on, you will stuck, when there appears 'SAMSUNG' logo & it keeps flashing after few seconds regularly. & it won't stop (untill a minute) When my mum came in Orange after the repairing.. they said some cable didn't touch properly another.
      This problem happened for the 2nd time. Orange (Yeah, the shop) said, that they won't give a permanent (until another problem, not hoping for..) replacement because though it's still under contract.
      Yeah, Orange can fix it, but when they have 'free days', what means 'CLOSED' for tommorow because of national saint's day/fete ... 'It will be fixed in 30 days, yet you have another phone. When they repair it, they will 'stole' nowadays' phone and give you the repaired one. All datas from the replacement phone are lost. When this problem will happen for the 3rd time, all datas will be again lost! (unless you set photos/vids on gmail photos to automatically save)
      Why this f4cking cable keeps not responsing?!

      And, also, that system is like, all you can do, is s4ck your 4ss. Orange won't do anything about monetization, just wait. F4ck th3m. (that numerization is kinda censoring.)
