LG G7 Keep Rebooting? Fixes That Work
If your LG G7 is stuck in a boot loop or keeps restarting on its own, the fix is usually a combination of clearing the cache, checking for a faulty battery, or performing a factory reset. This guide walks through the most effective solutions, from quick software checks to hardware-related causes, so you can get your phone stable again.
Why Your LG G7 Keeps Rebooting
The LG G7 ThinQ, like many Android phones, can enter a reboot loop for several reasons. The most common causes are:
- Software glitches after a system update or app installation
- Corrupted cache data that conflicts with the operating system
- Battery issues, such as a swollen or failing battery that can’t deliver consistent power
- Hardware damage from drops or water exposure
- Overheating, which triggers a safety shutdown and restart
Understanding the root cause helps you choose the right fix without unnecessary steps.
Quick Fixes to Try First
Before diving into more complex solutions, try these simple steps that often resolve the issue:
- Force restart: Press and hold the Power and Volume Down buttons simultaneously for about 10 seconds until the phone vibrates and restarts. This clears minor temporary glitches.
- Remove the SIM card and microSD card: Sometimes a faulty card can cause the phone to crash. Power off, remove both, then power on to see if the problem persists.
- Check for overheating: If the phone feels hot, let it cool down for 15–20 minutes before turning it back on. Overheating can cause automatic restarts.
- Charge the phone: A completely drained battery can cause boot loops. Plug it into a charger and wait a few minutes before trying to power on.
Clear the Cache Partition
Corrupted system cache is a frequent culprit behind reboot loops. Clearing the cache partition doesn’t delete your personal data, so it’s a safe step to try:
- Turn off the phone completely.
- Press and hold the Volume Up and Power buttons together until the LG logo appears, then release.
- If prompted, select Yes to enter Factory data reset mode (this is the wrong option—do not confirm it yet). Instead, use the volume keys to navigate to Wipe cache partition and press the Power button to select.
- Confirm the action and wait for the process to finish.
- Select Reboot system now.
If the phone boots normally, the problem was likely corrupted cache. If it still reboots, proceed to the next step.
Boot into Safe Mode
Safe mode disables all third-party apps, helping you determine if one of them is causing the reboots. Here’s how to enter it:
- Press and hold the Power button until the power menu appears.
- Tap and hold the Power off option until the Safe mode prompt appears, then tap OK.
- The phone will restart in safe mode, indicated by “Safe mode� at the bottom of the screen.
If the phone stays stable in safe mode, a recently installed app is likely the culprit. Uninstall any apps you added just before the reboots started, then restart normally.
Factory Reset as a Last Resort
If none of the above works, a factory reset will restore the phone to its original state. This erases all data, so back up anything important first. To perform a factory reset:
- Back up your data using LG Backup or Google Drive.
- Go to Settings > General > Backup & reset > Factory data reset.
- Tap Reset phone and confirm.
Alternatively, use the hardware key method: turn off the phone, then press and hold Volume Down and Power until the LG logo appears, then release and immediately press and hold Volume Down again until the reset screen appears. Select Yes twice to confirm.
Hardware Issues: Battery and Charging Port
If software fixes don’t stop the reboots, the problem may be physical. The most common hardware issue is a failing battery. Over time, batteries lose capacity and can cause voltage drops that trigger restarts. If your G7 is more than two years old, consider replacing the battery. Also, inspect the charging port for debris or damage—a loose connection can interrupt power and cause reboots.
Another possibility is a swollen battery, which can press against the internal components. If the back cover bulges or the screen lifts, stop using the phone immediately and seek professional repair.
When to Seek Professional Repair
If you’ve tried all the above and the phone still reboots, the issue could be a deeper hardware fault, such as a damaged motherboard or a loose connection between the battery and the board. In such cases, professional diagnosis is recommended. LG has authorized service centers that can inspect and repair the phone, but be aware that costs may exceed the phone’s current value.
Preventing Future Reboots
Once your G7 is stable, take these steps to reduce the risk of future boot loops:
- Keep the operating system and apps updated to the latest versions.
- Avoid installing apps from unknown sources.
- Use a high-quality charger and cable.
- Don’t let the battery drain completely on a regular basis.
- Monitor the phone’s temperature during heavy use.
Frequently Asked Questions
Will a factory reset fix the reboot loop?
Often, yes. A factory reset clears corrupted system files and settings that may be causing the loop. However, if the issue is hardware-related, the reset won’t help.
How long does it take to clear the cache partition?
Usually less than a minute. The process is quick and doesn’t affect your personal files.
Can a microSD card cause rebooting?
Yes. A corrupted or incompatible microSD card can cause system crashes. Try removing it to see if the reboots stop.
Is there a way to back up data if the phone won’t boot?
If the phone is stuck in a loop, you may still be able to connect it to a computer via USB and access files in recovery mode. However, if the phone never fully boots, data recovery may require professional tools.
How much does it cost to replace the battery on an LG G7?
Battery replacement costs vary by region and service provider, but it’s generally more affordable than buying a new phone. Contact a local repair shop for an estimate.
