Galaxy Watch 4

Android is great for most applications and multitasking, and for phones and tablets, you can quickly switch between the last two used apps by double-clicking the all-view button.

And with Samsung choosing the Wear OS for its smartwatches this year, faster app changes are now available for Galaxy Watch 4 and Galaxy Watch 4 Classic.

For previous Galaxy watches using Tizen, you can only double-click the home button to switch to the last application used on the face of the clock.

For new Samsung watches, you can double-click any home button to switch to the previous app you opened, and then double it again to return to the original one. It works as basic as it does on Android phones and tablets, and it’s very simple.

Switching apps on Galaxy Watch 4 using the home key

The home key is not provided for switching to the last application used on a double press, but it is easy to change that.

  • First, open the Settings app in your Galaxy Watch 4/Watch 4 Classic by swiping down the screen and touching the cache icon.
  • Scroll down and tap Advanced features, then navigate to customize the keys.
  • Here, simply tap the Double-press option under the Home key tab and select Go to the most recent app.

Of course, if you want to assign the action of pressing the home key to one of the other, you can choose from many other options. You can customize it by pressing and holding the home/power key, and the normal background button is reset.

It is also an excellent all-around tool, boasting a Qualcomm Snapdragon 888 processor and a three-lens rear camera system. On top of this, it goes fold out, making it great for you to do multitasking work and make a product, watch TV and media, and entertain your friends.

This gives you details on everything from battery discharge issues to issues with Samsung Pay, helping you make the most of your new phone and not letting small snags ruin your enjoyment.

As with our troubleshooting pieces, this article will be updated as we encounter new common issues, so please come back again if the issue you are facing isn’t covered yet.

Galaxy Z Fold 3

Camera app not displaying Dual Screen button for selfies – Issue

A number of users on Samsung’s Community forum have noted that, when trying to take a selfie in the Camera app, they don’t see the Dual Screen button.

Solution

  • Fortunately, there’s a very quick fix for this. As other Samsung Community users have noted, opening the Camera app from the cover screen (rather than the main screen) will ensure that the Dual Screen button appears where it should.

Screen protector problems

Some users of the Z Fold 3 have encountered a variety of issues with the phone’s pre-installed screen protectors. These problems aren’t always exactly the same, with some reporting bubbles and others reporting inconsistencies in the protector’s adherence to the screen.

Since such issues can be frustrating, you are strongly advised not to remove the pre-installed screen protector, especially when talking about a large folding screen. Instead, you should contact Samsung as soon as possible to arrange a repair or replacement.

On the other hand, at least one user asked if it was safe to remove the outer film that came wrapped in wire outside the box.

Unable to acquire GPS location in apps – Issue

Even though the Z Fold 3 has only just been released, some users have already complained that apps they use are unable to receive their GPS location data from the phone.

Possible solutions

This is an issue that has affected other Samsung devices in recent years, so you may simply have to wait for a software update for a fix. You can check if one is available by doing the following:

  1. Open the Settings app on your device.
  2. Scroll down to Software Update.
  3. Select Download and Install.
  4. If a new update is available, your device will obtain it.

Can’t activate unlocked Z Fold 3 on Sprint – Issue

This is one of the more complicated and difficult problems encountered so far with the Galaxy Z Fold 3. Quite a large number of United States-based users have reported that they can’t activate their phones on Sprint. This seems to be an issue arising from T-Mobile’s merger with Sprint and from how Samsung has optimized the phone (or not) for using a T-Mobile or Sprint SIM card.

As of writing, the only fix appears to be contacting T-Mobile and/or Sprint and trying a different SIM card (i.e., a T-Mobile rather than Sprint SIM). That said, some users have reported that the issue was resolved after several days, with a few noting that they were eventually able to activate their phones via either the T-Mobile or Sprint websites.

S Pen to Text not working properly – Issue

couple of users have reported that the Convert Handwriting to Text feature on their Z Fold 3 phones doesn’t work properly. Normally, this lets users of the Samsung Notes app handwrite a phrase or sentence and then convert it into normal text. Unfortunately, the affected users note that the process of conversion malfunctions, with random words appearing where they shouldn’t.

Possible fixes

  • As of writing, there isn’t a definitive solution for this. You may simply have to wait for a software update from Samsung and then install it, which you can do by going to Settings > Software Update > Download and Install.
  • Given the Samsung Notes app is responsible for converting handwriting, you may also want to try updating it. This can be done by going to the Google Play Store, searching for Samsung Notes, and then tapping Update.

How to improve battery life of your Samsung Galaxy S21 smartphone

Published

on

Galaxy S21

The Samsung Galaxy S21 series actually sports amazing excellent battery life. In Galaxy S21 and S21 Ultra, it is that found that it was really impressive. Especially for the S21 Ultra as it worked with QHD+ configuration and 120Hz refresh rate. But there are always ways to improve battery life on your smartphone.

In this article, we will give you a few different tips that you can use to improve the battery life of your Galaxy S21 smartphone. And make it last longer, if needed.

Adjust screen resolution & refresh rate

The display will always be the most demanding part of your phone when it comes to battery life. Especially if you have a Galaxy S21 Ultra, which has that 6.8-inch display. So one of the easiest ways to improve battery life is to adjust the screen adjustment and refresh.

Now, Samsung is doing an Adaptive update rate, so it doesn’t always work at 120Hz. But if you are using a Galaxy S21 or S21+, the only option you have is to lower it to 60Hz. Since none of this allows for a lower resolution. It stuck to FHD + at all times.

On Galaxy S21 Ultra, you can choose to release screen adjustment to FHD+ from QHD+. However, if you have not adjusted that setting out of the box, you may still be using FHD+. And in that case, you may want to lower it to 60Hz. These changes can actually make a huge difference.

Switch to dark mode

For many, this is a common concept, but for others, this needs to be said. Switch to dark mode. It is easy on the eyes, and will also save your battery life. This is because all Samsung smartphones use OLED displays. These displays illuminate individual pixels. So when more pixels are dark, the extra pixels are off and not working.

Google actually did some testing on this and found that a black background can use much less energy than a white background. It uses less than 63% of power, which can make a huge difference in the battery life of your smartphone.

Another tip here would be to use a very dark background wallpaper. Even if you rarely see the background image on your home screen. This can make a big difference too.

Check your battery statistics

An excellent way to improve your battery life is to simply check your battery statistics. The reason for this is that you can see which apps are hungry for energy. And which ones have gone wrong.

For example, Google Play Services tends to misbehave every once in a while. And you can force stop the app to help your battery drain. Sometimes other apps like Facebook and Twitter use more power than they should.

Additionally, you can adjust whether some apps are running in the background. Which may also use a very small battery.

Use Wifi instead of 5G

This is a long-term battery life tip, and it still hasn’t changed. But use WiFi instead of 5G. Unfortunately, Samsung does not allow you to turn off 5G, like other smartphones. But if you’re at home – most of us still – be sure to keep WiFi turned on.

This is good for your battery, but it is also good for your own taste. Since your WiFi is probably faster than 4G LTE or 5G in your area. So Twitter, and other apps will instantly upload to WiFi.

Turn on power saver mode

Lastly, if it is very bad, it is a good idea to turn on Turn on power saver mode. That can really extend battery life to your Galaxy S21. You can get to the save mode in the quick, easy settings, and battery settings panel.

Power Saver mode usually slows down the processor, as well as blurs the display. It will also stop certain notifications. So this is not something you can leave all day. But if you are under 20%, it might be a good idea to turn it on and get some extra juice on your phone. At least until you can charge your phone.
