Remember the good old days when you would brag about your phone receiving 5 bars of signal strength in certain locations? Your friend might reply by noting that his phone had only 2 bars in the same spot. And strangely enough, that would make you feel superior to your pal, at least until you found the roles reversed at a different location. Well, if some commits discovered by XDA on the Android Open Source Project are implemented, carriers might decide to no longer provide subscribers with this information beginning with the Android P build.
This information in numerical form can be found …
Earlier this year, T-Mobile quadrupled its low-frequency spectrum by acquiring a large portion of the 600MHz spectrum in the US. By the end of the year, the carrier is expected to have upwards of 1 million square miles of coverage in the 600MHz range.
Lower frequency signals, such as the 600MHz one, travel farther and ‘deeper’ than, say, higher frequencies, such as the 2.5GHz band that Sprint widely utilizes. Higher frequency signals are usually the reason to experience connection issues inside of buildings and complete absence of signal when you are in the subway, for example. The 600MHz …
As we all know, using a smartphone while driving a car can be quite a dangerous thing. And we all know why we should pay attention to the road, not to the phone, right? A recent study confirmed that even using a hands-free system can be just as distracting for drivers as holding the phone to the ear, not to mention texting while driving. Of course, there are some apps available that claim to reduce the distraction (as for example Samsung’s “In-Traffic Reply”), but their effectiveness is still to be proved in practice. Nissan, however, has another idea – the company bets …
Dialing A Secret Number Will Tell iPhone Users How Much Signal They Really Have.
If you’ve ever found yourself wandering about a room, holding your phone up to the sky searching for a signal, this is just the trick for you. Edward from Redmond Pie found a great way to configure the readout with just a simple phone call, making your iPhone display its exact signal strength in decibels (dBm).
Step 1: Put Your iPhone into Field Test Mode
Dial *3001#12345#* and press call.
This will put your phone into Field Test mode, where you’ll notice a signal strength indicator in the left-hand corner of the screen. You can tap on the signal bars to switch it to a numerical value and vice versa.The closer the number is to 0, the stronger your signal. So, a -60 would be stronger than a -93, and a 0 stronger than a -60.
Step 2: Make It “Permanent”
To keep this feature even after exiting the app, hold down the Power button until the Slide to Power Off bar appears. However, don’t power off the device.
Step 3: Close the App
Press and hold the Home button until the app closes and it returns you to the Springboard. You should now see your signal strength in dBm in the upper left-hand corner.To reverse this process and go back to the default display, dial *3001#12345#* again, press call, then press the Home button once. You can always re-enable the feature as needed.
For Android Users
Android users have it a bit easier. While you can’t replace the bars with the dBm reading by calling a number, you can see it by going to Settings -> About Phone -> Then navigating to an option such as Status (it will depend on your phone) to see your signal strength.
