Rugged Phone Repair

If your hobby or your work takes you to wild or dangerous areas and you're looking for a smartphone that will last for a long time, the rugged smartphone is what you need. Unlike normal smartphones, rugged smartphones are fully sealed smartphones in thick housing to protect against damages such as water, shock, dust, and vibrations.

The best-rugged smartphones are made to withstand the drops on stones or hard surfaces and are usually water and dust resistant, sometimes even waterproof. In most cases, these phones can withstand any drop, bump, or impact without causing any damage to the phone that makes it ideal for outdoor use. Such devices have been tested strictly to ensure they comply with military requirements and shock safety, high temperatures, and of course, dust and water. Rugged phones are specifically designed for constructors, plumbers, carpenters, electricians, site workers, etc. People who are into adventurous sports may also find rugged phones useful.

Common Issues With Rugged Phones

1. Your phone is running slowly

One of the most common issues with any smartphone is the phone running slow or getting laggy especially as your phone gets older. The reason behind this is the installation of unnecessary apps that consume most of the RAM of your phone also it saves large numbers of files.

The best solution is removing all the unwanted apps and clearing up your cache data. Even then if you are facing the same issue restore the phone to the factory settings.

2. Poor Battery Life

Almost every phone faces this issue at some point in time, as phones get old the battery life gets reduced. The common problems associated with damaged batteries are battery draining, slow charging, or charging failure. You could easily identify the problem when the phone discharges without being used.

You can check whether any specific app is consuming too much power in your settings and uninstall those apps. If the problem persists the best solution is to get the battery replaced at The TechKnow Space.

3. Smashed or Cracked Screen

More than half of the smartphone repairs are caused when the screen is cracked or broken. As phone screens are getting larger every year, drops are becoming more risky and damaging. The only solution to a damaged or cracked touch screen is a quick screen replacement. So users need to find a reputable mobile service center that can quickly replace the screen.

4. Charging Port Stopped Working

Like phone batteries, the charging cables and ports wear down with time. As you charge once or multiple times a day there is a high chance over time the charging port can get dirty or get scratches which can hinder or slow down its charging capabilities. So you're likely to replace or repair your charging port before you reach full life expectancy. The techknow space can get your rugged phone repaired and running in no time.

5. MicroSD Card Not Working On Your Smartphone

This can be caused when your SD card has a poor read/write error. If you're sure that the sd card is not broken you can try formatting the microSD card. In case if the sd card is covered in dirt it may not read, use a clean white eraser to remove the dirt from the card.

6. Connection problem with Bluetooth, wifi, cellular network

Connection problems can be temporary problems that can be solved by keeping the phone on airplane mode for 60 seconds and trying to reconnect. If you are still facing the issue the receiver or antenna may be faulty so it must be replaced.

7. Overheating

Moderate overheating may not be of great concern, extreme overheating may in fact inflict irreversible damage to the cell phone itself, not to mention the risk of harming you or anyone else. if your device is getting heated frequently It may be that the real chipsets inside your mobile phone are responsible for the overheating issues. The only solution is either to get it repaired or replaced.

8. SIM card reader/slot issues

If your phone is not detecting your sim card then mostly your sim card tray could be loose or broken or there may be a problem with the SIM card reader. If your sim card tray is broken it can be replaced and if there's an issue with the sim card reader It usually involves repairing the SIM card reader on the main logic board.

9. Liquid/water damage

Water damage may cause major problems, making it useless and data lost for good with the fragile internal circuitry of your phone. Was your system accidentally dropped or hanging by the dog into the toilet? Have you jumped into the pool, left in the rain, or thrown your phone accidentally?

10.Audio output issues

Approximately 5 percent of all smartphone repairs are to address a faulty or malfunctioning sound system, speaker, loudspeaker, or microphone. The smartphone does not have a sound output mostly when the audio jack is damaged or disconnected. At other times, the volume control buttons are disconnected or damaged and therefore need to be replaced.
