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!

    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...


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

    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.)


  • My A5 KEEPON GOING TO MUTE EVEN IF I DONT SET IT ON MUTE

      Mine too! And sometimes even when the sound is on, no sound comes out from the speakers and i have to restart my phone.


      • Yup same problem here and also my videos stuck and dont play without any reason then i have to restart the phone. Any solution to this problem or did you claim the warranty?


      • Man I exactly have the same problem . It usually happens when I'm using my headphones. I have yo restart he phone everytime.


  • I've got the a5 2017, only had it about a month and it also keeps dropping off my Wi-Fi, my partner has a5 2016 and the fone I had before this was a5 2015 and none of them dropping from the Wi-Fi, only seems to b this fone, it's like it keeps hanging and I need to disconnect it from the Wi-Fi and then reconnect it and it's starting to frustrate me a little other than that it's a gd fone. Any help would b great.


  • I've had my A5 2017 since February and it has been a great smartphone but I've recently experienced WiFi connections at work and home dropping out on me regularly.

    It does drop out at work as the siganl is poor but it doesn't seem to retain the WiFi login when I try to reconnect whereas previous phones it automatically logged back in when it connected.

    At home it drops out in favour of alternative public WiFi in my neighbourhood for some odd reason.

    This doesn't happen on any of my other devices at home, just this phone and I keep it up-to-date regularly.


  • I have a Galaxy A5 2017 too. My prolem is the data usage... I have a Vodafone pocket router and I have in 12GB of internet. I know It's weird, but... the ANDROID OPERATION SYSTEM drains my internet very quickly and I have no idea why. I hope it's one of the infinity bugs of the Marshmallow and when I update soon to Nougat, this bug is gone. Any idea what is the problem? Anybody have this problem too? I need to know, I spent a lot of money for this mobile and I really love it, but... I start to hate this Galaxy a little. If you know what's the problem, please reply me. Thank you! :)


  • I have a A5 2017 running on marshmallow, the issue i have is that sometimes when i'm playing a game the back navigation button stop responding and the same thing happens when i plug in earphones. I've tried several different earphones, at first it works smoothly but after a while it stops responding. Then i have to press (literally press) the back navigation button hard enough for it to work. I tried giving it to several mobile repairing shops but they do not seem to know how to repair it. They say its a software issue because if it is a hardware issue it would not be working on and off. They tried reinstalling the firmware but there was no success. Anyone else has this problem or possibly any solution?


  • İ have problem with watsapp syncronisation problem in my a3 2017. Unles I touch on watsapp icon, İ cant see the last messages. the same is for Gmail on my A3 2017. İ need to sync manually. what is more, İ cant call back the last incoming call as the number is beeing seen without zero (0) at the beginning on incoming call. Any one else?

    Been using the a5 since feb and haven't had this issues.. Battery life is great.. FP scanner is also great. Also have friends using a5 and a3 and none of them have this said issues.


  • I had A5(7) for a whole week, none of this wasn't the issue. Battery could last for a day of heavy using, day and a half of some medium using like social apps and chatting, and day for some really hc use. Fingerprint worked perfectly, not like A5(6) which is not so accurate, at this phone worked so good. Reason why i switched it for P9 its because of its glassy look, too fragile i think.


  • Usually i dont leave comments on any article because i agree with them but with these problems as a A5 (2017) user i didn't find any of these problems as these are fully fake
