Samsung Galaxy A70 common problems and how to solve them

Samsung has firmly re-entered the midrange segment this year. Users already love the company’s budget champion, the Galaxy A50, and its bigger brother, the A70, only improves on an already strong base.

Sure, the A70 might not be the best value for money in the whole A series, but it offers something authentic. It brings a good portion of the Galaxy Note experience with its huge AMOLED display. Only for the chunk of the price. If you value big phones, but don’t want to spend a small fortune, the Galaxy A70 is a way to go. You probably think the same way, and that’s why you just bought this device.

But then, the first problems start to appear. And there aren’t too many things as annoying as problems on a phone fresh out of the box. That’s why I compiled a list of the most common problems with the Galaxy A70 for you. Just find the issue that’s bothering you, and you’ll either find a solution, or understand the problem better.

Note: All the issues mentioned in this article are individually reported cases, and they might never occur on other devices. If you’re looking to buy this phone, and stumbled upon this article while researching, DON’T take these problems into consideration.

1. Touch screen issues

When the phone’s highlight feature is its display, the last thing you’d want or expect is some screen-related problem. Unfortunately, that appears to be exactly the biggest problem with the A70. Forums are flooded with reports complaining about touch screen issues, of whom the biggest problem appears to be the multi-touch.

Apparently, users are having multi-touch issues in games that use the movement stick, like PUBG. Namely, when you drag the stick to keep moving, it stops registering your finger, so you have to lift it and press the stick again.

I couldn’t find a solution to this problem anywhere. That means Samsung will probably address it in an update. However, there are reports about users already receiving an update that claims to fix the multi-touch issue, but it still persists.

I can only advise you to keep checking for new updates, and hope for the best. Hopefully, Samsung will deal with this problem once and for all in the future.

2. Wi-Fi problems

One user has reported on Samsung forums that he’s unable to connect to his home Wi-Fi network. Other than that, Wi-Fi doesn’t appear to be the problem on the A70. Nevertheless, if you can’t connect to a Wi-Fi network, make sure everything’s okay with your router first.

If you can’t connect to any Wi-Fi network, try some of the solutions listed in this article.

3. Overheating issue

Just like the reported Wi-Fi problem, overheating doesn’t appear to be a widespread problem with the Galaxy A70. However, it’s been reported, so I feel like I should include it, anyway.

If you’re experiencing overheating on your brand new Galaxy A70, try some of the following workarounds:

  • Disable background services, like Bluetooth, NFC, location, etc.
  • Lower the screen brightness.
  • Disable the always-on display.
  • Try a different case.
  • Install the latest updates.

4. Fingerprint scanner not working

Another new feature the A series brings to the table is the in-display fingerprint scanner. And once again, the real-life results are great, to say the least. There are numerous reports on the forums about the A70’s fingerprint scanner either being slow or not working at all.

Sure, this is still a first-generation technology, and you shouldn’t expect it to work flawlessly 100% of the time. Plus, the fact that Samsung doesn’t use premium hardware in the A70 doesn’t help. But still, you want it to function to a degree where it’s at least usable.

Some users have reported that the fingerprint scanner started working normally after a few updates. On the other hand, some say the issue persists even on up-to-date devices. So, the only thing left for you, if you’re experiencing the fingerprint scanner issues, is to keep checking for updates and hope for the best. If the problem persists, consider replacing your phone at the store.

5. Lags while gaming

A few reports suggest that users are expiriencing lags while gaming. Esentially, this is true, but it’s probably not a problem per se. This alleged lagging issue is actually CPU throtthling caused by a high temperature. In case you’re not familiar with the term, when your phone reaches a certain temperature, it automatically “throttles” the speed of both GPU and CPU to prevent overheating. That process is called “throttling”.

So, if you’ve been gaming for an extensive period of time, your phone will reach a certain temperature, and it will throttle the power of your hardware. Which means you’ll have less resources to work with, and your performance will suffer. Especially in more demanding games.

In that manner, if your game starts stuttering, just put your phone down for an hour, and let it cool off. You shouldn’t experience any more lagging problems afterwards. Additionally, this can also happen if your phone already overheats, like mentioned above. In that case, try some of the recommended solutions to prevent overheating.

That’s about it. As you can see, there aren’t too many things to worry about with the A70, which makes this phone a pretty sure bet. Sure, possible touch screen problems could get annoying but you’ll get used to it eventually. And who knows, maybe Samsung will resolve everything with a future update.
