How to troubleshoot LG G7 ThinQ that became so slow

Before you troubleshoot your phone, try to determine if the problem is isolated to an app or not. It’s possible that your device is just slowing down when running a certain app. To figure this out, try to run different apps. If your phone runs slow only when using a certain app, then that denotes that the problem is isolated to an app. In that case, you will need to deal with apps problem. But if your phone is showing the same symptom regardless of which app is running, then you will need to fix software problems that might have caused conflict and eventually slowed down your phone.

First solution: Force stop background apps then reboot/soft reset your phone.

Errant apps are usually the main reasons as to why a device slows down suddenly. Background apps that have crashed or were corrupted might have caused conflict and adversely affected the entire system operation. To clear this out, force close all background apps on your LG G7 ThinQ with these steps:

  1. Tap Settings from the Home screen.
  2. Go to Apps & notifications.
  3. Tap App info.
  4. Tap on an app to force stop.
  5. Then tap the Force stop button.
  6. Read the message prompt then tap OK to confirm.
  7. Follow the same steps to force stop all other background apps.

After clearing all background apps, reboot your LG G7 ThinQ to dump cache from the internal memory. Doing so will help free up memory space and allows the device to perform better in the next run. Here’s how to reboot/soft reset your LG G7 ThinQ:

  • Press and hold the Power button and Volume Down button simultaneously for a few seconds and then release both buttons when the phone reboots.

A soft reset does not affect saved data on the internal memory and therefore won’t result to data loss. Minor software errors are usually rectified in the process.

Second solution: Enable safe mode and diagnose apps.

Third-party apps that contained some bugs and malware can also trigger similar issue on your phone. This is likely the underlying cause if your phone suddenly slowed down after installing a new app. To determine if it’s really a third-party app that’s inflicting such trouble, try to diagnose your phone in safe mode. Enabling safe mode only allows pre-installed apps to run. If your phone does not slow down while in safe mode, then a third-party app is the trigger. So follow these steps to enable safe mode on your LG G7 ThinQ and then start diagnosing apps:

  1. With your phone screen on, press and hold the Power button until the menu options appear.
  2. Press and hold the Power off option.
  3. When you see the message prompt to Restart in Safe Mode, tap OK to confirm.
  4. Wait until your device restarts in safe mode. You will then see the Safe Mode label at the bottom of the screen.

You may have to delete or uninstall individual apps starting from your most recent download, if the problem does not occur in safe mode. Otherwise, your phone needs service.

Third solution: Update phone software and apps to the latest version.

The latest Android version available for LG G7 ThinQ is Android 8.0 G710TM10g. This update was officially made available for selected Android devices including the new LG smartphone on the 11th of July, 2018. It offers various bug fixes and system enhancements. If you haven’t installed this software version on your phone, then you may have to consider doing so. This will likely remedy your phone’s sudden sluggishness especially if software bugs are the main culprit. You can download and install the latest Android version over the air (OTA) with these steps:

  1. Tap Settings from the Home screen.
  2. Go to the General tab.
  3. Tap Update center.
  4. Select System update.
  5. Tap the option to Check for update.
  6. Follow the onscreen instructions to download and install the latest software update on your LG G7 ThinQ.

Your phone must have Internet connection preferably through Wi-Fi, at least 50 percent battery life and ample of storage space for the update file.

You can also update your LG G7 ThinQ software from a computer. Just be sure to download and install the compatible software for the LG Bridge on your computer to get this done.

Fourth solution: Wipe cache partition on your phone.

If your phone suddenly slowed down after installing a new update for apps or Android system, then wiping cache partition can potentially solve it. Errant system caches are likely causing conflict and thereby results to a sluggish system performance. To clear this out, follow these steps to wipe cache partition on your LG G7 ThinQ smartphone:

  1. Tap Settings from the Home screen.
  2. Go to the General tab.
  3. Tap Storage.
  4. Select Internal storage.
  5. Tap Free up space from the menu options.
  6. Tap Temporary files & raw files.
  7. Select the given options including cached data, clip tray temporary files, and raw files from camera.
  8. Tap Delete twice to confirm.

Reboot your phone after wiping cache partition to clear its memory and refresh the Android system.

Fifth solution: Reset and restore your phone to factory defaults (master reset).

If wiping cache partition does not work, then you may need to resort to a full system reset. This however should only be considered as the last option to rectify fatal system errors that may have slowed down your LG G7 ThinQ. If you wish to continue with a master reset, be sure to back up all your critical data because they will all be wiped out in the process. Once you’re all set, follow these steps to reset and restore your LG G7 ThinQ smartphone to its factory defaults:

  1. Tap Settings from the Home screen.
  2. Tap System.
  3. Tap Restart & reset.
  4. Select the option to Reset settings.
  5. When asked, tap Reset Settings to confirm.
  6. Enter your device PIN or password, if prompted,
  7. Then tap OK to proceed.

Allow your device to finish the master reset and then reboots automatically when done. As soon as it’s finished rebooting, you can continue with the initial setup process and set up your phone as new. Software errors should also be gone by then and so your phone should be back up and performing as fast as it’s supposed to be.

Other options

If you’re using an SD card, try to unmount and remove the SD card. Some people who have dealt with the same issue on their new Android smartphones have later found out that a bad SD card is causing conflict. There may be some files or data segments in the SD card that were corrupted and eventually affected the phone’s overall performance.

If none of that helps, then you can escalate the problem to your carrier and ask help to troubleshoot your device further. Otherwise, take your LG G7 ThinQ to an LG authorized service center and have it assessed thoroughly by a technician. Your device may have obtained some sort of physical or liquid damage that might have caused it to slow down unexpectedly. If service is needed, don’t forget to avail for service warranty.
