1] Broken Phone Screen

Do you know most of phone users all over the world have experienced the broken screen issue at least once? The key reasons for this to happen are:

  • An accidental fall
  • Slipping the phone down due to juxtaposing at a crowded place
  • Sitting on the phone while it’s in the back pocket
  • Accompanying the phone with metal keys in the pocket, etc.

While it’s obvious to panic seeing your damaged phone screen, you better avoid wasting too much time over regretting and look for the possible solutions around. Check if your phone screen is covered by your manufacturer’s warranty or some insurance. Some phone brands provide screen protection under their warranty.

When the phone screen gets damaged, the most feasible option is getting it repaired or replaced from a reliable repair center, preferably at your brand’s authorized service center. This will ensure you get an original screen replacement professionally and affordably.

2]Charging Port Issue

When your phone experiences slow or no charging, often the prime culprit is a faulty charging port. There’s a small metal connector in the USB Port that is not connecting to the charging cable properly. The reason could be any of the below:

  • Dust or debris blocking the contact or preventing proper power supply to the device.
  • Caused by corrosion when your phone gets wet or you put it in a high humid environment.
  • Hardware damage, usually when you drop the device

You can successfully fix this issue at home if it is not hardware-related. Clean the port using a needle and soft cotton. Adjust the pin gently to the center, or as per your charger’s pin shape.

But before you try this trick, don’t forget to use a different data cable and charger so as to confirm that it’s the port that’s at fault.

If the problem persists, do visit your nearest service center for a professional cell phone repair.

3] Water Damage 

Did you spill tea/coffee on your phone? Or your phone took a dip in a water tub/swimming pool or worse in the toilet? Whatever the reason, water damage is nasty and often comes with irreversible issues to your smartphone.

You can try the below tricks to save your phone from water damage.

  • Remove your phone from the liquid and turn it off immediately  
  • Split up all components like battery, SIM Card, SD card, protective case, and place them at a dry place.
  • Use a soft cloth or cotton to remove the water from these parts
  • Try the classic rice or silica gel trick to bring your phone back to life. Take a bowl full of rice or silica gem in a plastic bag. Keep your phone in it for a couple of days. These tricks have proven effective for many lucky users.

Prevention is always better than cure. You can protect your phone from liquid damage using a waterproof pouch (easily available in the market) while you head off to the pool or beach. The pouches also prove effective when you’re out in rain carrying your phone alongside.

4] Battery Draining Fast

This is yet another common phone problem that phone users often come across for cell phone repair. First let’s understand why your phone starts running out of battery faster than usual, and then their fixes as below-

  • Not closing the background apps: Make sure you close the apps when they are not in use including the ones running in the background.
  • A third-part app or system Glitch: in that case, rebooting your device can be an effective solution. If needed, use your phone in safe mode. If the battery act normally in safe mode, the issue is related to a third-party app. Then, you should delete the recently downloaded apps.
  • Using too many apps also turn out to be a battery sucker. Delete the apps that you don’t use. Also, check if any particular app is consuming too much power. Settings >> About Phone >> Battery Use. Look over the list of apps and how much battery they consume. You can delete the apps which are of no use but still consume the battery.
  • Update the phone system and software to the latest version. You can check through Settings >> System Updates to find if any update is available for your phone.   
  • Too many notifications and ads popping up frequently. You can close them. Settings >> Manage Apps >> Notifications. Disable the notification as per your needs.
  • Poor Charger or charging pattern. Make sure you use the original charger. Also, use the 20-80 rule in charging. This means always keeping your battery charging between 20-80%.

5] Speaker Not Working

If your phone speaker starts causing problems, the foremost thing you should check is the headphone output. Is your device still in headphone mode? If yes, then perform the phone rebooting. This should clear up the mess caused by any faulty app.

Next, make sure the speaker settings are accurate. Check if the volume is set too low. Increase the volume and see if it works.

Another thing that needs your attention is the “Do Not Disturb” mode. Make sure it’s not enabled as this may prevent the speaker from functioning properly. You can check it through Settings >> Do Not Disturb.

If the above methods don’t work, try ‘factory reset’ as your final attempt to resolve the “phone speaker not working” issue at home. Don’t forget to take the data back beforehand, as the factory reset erases all the data from your phone.

  • Navigate to Settings >> Mobile Network. Ensure your mobile data is ON. And you’ve selected the correct SIM for internet use.

  • Make sure the battery is sufficient to use a flashlight. In several phone models, the flash is disabled the moment the charging goes below 15 or 10%.  
  • Using the flash too much may cause it overheating, and it stops working. In that case, wait for a moment and try again.
