The LG G4 turned out to be a real flagship, but even the most exemplary smartphones are not without flaws. In any gadget you can find both strengths and weaknesses, some shortcomings and strange errors. However, don't worry, we have solutions for LG G4 problems and we will share them with you.
If your LG G4 keeps rebooting on its own, then the first thing you need to do is check that all applications are updated to their latest version. Go to Play Store to the “My Applications” tab; in the menu on the left.
If the problem persists, then you will have to reset the settings to factory settings. But don't rush! First, make sure that all the necessary files from your phone are transferred and saved on another device. Google Photos is useful for backing up photos, and the rest of the content can be uploaded to Google Drive. Once this procedure is completed, go to “Settings”, then “General”, after “ Backup copy and recovery", then "Restore factory settings".
2. Battery drains quickly
If the battery is draining faster than before (and this did not happen gradually, but in an instant, especially if there were some new installations or updates), then check which programs are consuming the most energy and remove them (or look at the settings, perhaps any background processes are running). If even after this the problem cannot be solved, then you should also reset the settings to factory settings. How to do this is already written above.
3. Some notifications disappear
If notifications are not displayed on the lock screen, then go to “Settings”, then “Sound and notifications”, after “Lock screen” and make sure that the “Show all notifications” option is checked.
4. The screen does not respond to touches
There was official advice on this matter from a member of the company's marketing department in the US, although it concerned the LG keyboard. It was advised to update it by going to “Settings”, then “General”, after “About phone”, then “Update Center” and “Application Update”. Of course, this will only help those who are facing a problem with the keyboard.
5. Slow performance and a lot of lags
There is not a single reason why the LG G4 would have problems in terms of performance. The device has the most powerful and latest hardware installed. However, we do not exclude the fact that perhaps some application requires too many resources or some background process"hanging" in random access memory. Check this moment.
For some, the following advice may be helpful. In “Developer Options” (“Settings” - “General” - “About phone” - “Software information” tap on the build number 7 times) find the transition animation scale and set the duration within 0-0.5x in order to speed up interface.
Some users report improvement after disabling dual-window mode (Settings - General), while others decide to install a more stable third-party launcher, such as Nova Launcher.
6. LED indicator is constantly active for no reason
On XDA Developers they simply advise turning the LED on and off in “Settings” - “Sounds and notifications”. Also try turning off the alarm and then locking the display. Make sure the indicator is also no longer on.
7. Bluetooth or Wi-Fi does not work
Often, a banal reboot or reconnection to the network solves the lag that has arisen, but sometimes the solution to the problem lies in the little things. Check to see if your smartphone is in Power Saving mode. Also make sure that the problem is not coming from the router. Try connecting other devices to the Wi-Fi network or reboot (check the settings) of the router.
8. Overheating problem
It's normal to feel a little warm when playing heavy games, but never leave the device in the sun. If overheating problems are persistent, then you may have damaged the case in some way and now some part is preventing heat dissipation. The program may also be to blame. “Safe Mode” will help make sure of this.
9. Slow charging
The LG G4 supports Qualcomm's QuickCharge 2.0, but the included charger is a basic one and may seem slow to charge. There are also known compatibility issues with some third-party fast chargers, so first try changing the model and make sure that the charger's output current is sufficient for your smartphone.

Based on materials from AndroidPIT
It often happens that the owner of an LG phone is unable to use the device because he simply cannot turn it on. In this case, the phone may show signs of life, but still not boot to working condition. That is, there are several options for such a malfunction:
- The phone does not turn on at all;
- Stuck on loading screen;
- Installs updates;
- Disables immediately after loading;
All of the above options are quite relevant for owners of LG phones; it should also be noted that several reasons can lead to these types of malfunctions.
- Device falling, impact, mechanical damage;
- Excessive moisture entering the device;
- Loss of phone battery capacity;
- Complete battery failure;
- Insufficient battery charge;
- Operating system malfunction;
It is these reasons that most often determine the cause of the breakdown; some of them the owner can easily cope with on his own, while others are best entrusted to the professional employees of the LG service center. If your lg phone won't turn on, you can take the following steps in an attempt to fix the situation:
Battery check
The first thing you should pay attention to is the device’s battery, it is quite possible that it is faulty, this happens not only with well-worn phones, but even with new lg smartphones. You can check the performance of the battery in several ways, the most effective is to connect a 3.5 watt light bulb to it; if it is charged at least half a percent, it will function.
There is also special electronic equipment that can show the performance of the battery, but such equipment is available to repair shop technicians and it makes no sense to buy it specifically to test one battery.
The problem with the battery is solved mainly by purchasing a new one, this is the most effective way.
OS
If the malfunction concerns the operating system, then usually the lg phone does not turn on completely, that is, home screen the company logo appears and that’s all, the loading does not proceed further, and there are no messages about possible error does not appear, usually in this case only flashing the device’s firmware, that is, installing a new operating system, can help.
In order to flash your phone you need Personal Computer and the file itself with the operating system, without certain knowledge in the field of phone maintenance, it is better not to try to flash LG yourself, since inept actions can only do harm.
After the OS is installed, all user files will be deleted, but this is perhaps the only disadvantage of this process. When you turn on your phone for the first time, the system will prompt you to standard settings, language, date and time, after which you will be able to use the updated lg.
Microcircuits
If the lg does not turn on after a fall, the reason may be damage to the microcircuit, in which case only the intervention of a specialist can correct the situation. For many years, the LG service center has been helping users of the manufacturer’s equipment to bring devices back to life, thereby saving on the purchase of new ones.
Even if you simply undertake to disassemble the smartphone yourself, you can damage the component parts.
If the lg phone does not turn on because it is wet, you should not try again, turning it on while it was wet was a big mistake, the microcircuit will be damaged, and as a result of a short circuit, many parts of the device will have to be changed after that, but if you let it dry and treat the contacts properly , then perhaps performance will be restored.
Literally a month after the official release of the LG G4 model, a survey was organized on the well-known XDA forum. Visitors had to answer only one question: what's broken in your LG G4? Judging by the responses of users, 114 people (65% of survey participants) indicated problems with touch screen G4.
In the corresponding forum thread, one of the users then spoke about problems with the digitizer of their LG G4 (by the way, we are his), someone about white lines on the screen, and someone about the fact that in “sleep” mode The smartphone screen does not react in any way to a standard double press and does not unlock.
And since, in response to requests from the XDA administration, LG only offered to wait for routine updates and did not even specify whether these problems were of software or hardware origin, the public, as usual, began an independent collective search for options to resolve some problems.
And, I must say, not without some positive results.
In this regard, briefly about what to do if problems arise with touch panel screen of LG G4 smartphones.
- First of all, we remove the screen protector (protective film) and analyze the result to see if there is a difference in the operation of the screen. If a positive effect is not detected, and the screen continues to be “dull” and/or does not respond to touches at all, then...
- trying to update the application virtual keyboard: “Settings” -> “General” -> “About phone” -> “Update center” -> “Application update” ;
- Then you can speed up the processor, to do this tap “Settings” -> “General” -> “About phone” -> “Software information” , then – 7 (seven) times press “ Build number " until the message " You became a developer", after which again “Settings” -> “General” -> “Developer Options” and tap " Speed up the GPU «;
- in some cases, the problem is resolved by simply restarting the smartphone.
If all of the above methods do not produce the desired effect, then most likely there is a hardware problem with the LG G4 screen. Simply put, you need to replace either the entire screen (see link above) or just the digitizer. However, the panel with the digitizer for the G4 is usually sold assembled, therefore, taking into account the potential difference in price, searching for only a digitizer, according to available data, does not make much sense.
Let us only recall that the procedure for replacing the screen on an LG G4 requires some knowledge and experience, therefore, in the event of a deficiency of the first and/or second, it is better to entrust this matter to a qualified specialist.
We're big fans of the LG G4; the phone boasts a stunning display, great camera, stylish design... But, unfortunately, we have not yet met ideal devices, and recently various problems with the LG G4 began to surface. Here we presented the most important of the identified problems, and for each of them we offered our own solution.
Problem: Touch display does not respond to touch
Many LG G4 owners complain that the display responds late to clicks or completely ignores them. It seems as if the display sensitivity is reduced and clicks are simply missed.
Also, users complain that to select special characters On the keyboard you need to hold the keys down for a very long time.
Worth a try:
If your main problem is with the keyboard, then try using a third-party option from the Play Store - for example, Google Keyboard.
- LG is already aware of the existing problem, and the head of marketing in the US, Baz Jensen, on his Twitter advises updating the LG keyboard by going to the menu Settings > Are common > About the smartphone > Update Center > Application Update. This will help get rid of problems with the native LG keyboard, but will not help if the problem occurs elsewhere.
- If you use a protective film or case, you should remove them and check whether the display changes after that.
- Some users have noticed that the problem is partially or completely resolved after enabling forced rendering in the developer options. To activate them go to the menu Settings > Are common > About the smartphone > Software information, find the “Build number” item and click on it until you see the message “You have become a developer.” Return to Settings > Are common, where you will now find a new item - “Features for developers”. Go into it, turn on forced rendering and check if anything has changed in the way the device works.
Problem: backlog
Many users have complained about lagging performance on the LG G4, and it is possible that this has something to do with the display sensitivity issue. Most complaints are related to switching between applications or navigating on a smartphone. LG G4 - powerful smartphone, which should not have problems with task execution times, so we advise you to try the following solutions to this problem:
Worth a try:
- You can try installing another shell, such as Nova Launcher. Many users have noticed that the phone works faster with it.
- Someone's phone slowdown decreased after turning off the “Double Window” function in the menu Settings > Are common. This may help, because long pressing the Back key turns on this feature and multitasking mode.
- You can also try the old animation trick. By clicking several times on the build number in the menu Settings > Are common > About the smartphone > Software information, activate “Developer Features”. Now on the menu Settings > Are common You will find the item "Features for developers". You will need to go to this section and switch the window animation scale, transition animation scale and animation speed to 0.5x or off completely.
Possible solutions:
- Disable or uninstall any apps and games you don't use.
- It might be worth doing a factory reset. Make sure you do backup all the necessary files, then go to the menu Settings > > Reset.
- Many owners claim that they have no problems with delays and lags in the operation of the smartphone, so perhaps you should contact service center or contact the seller for a replacement device.
Error: LED blinks, but no notifications
Some LG G4 users are annoyed by the notification light blinking for no reason. When checking, you realize that there are no new notifications, but the diode still continues to blink.
Worth a try:
You can simply turn off the indicator. To do this, go to the menu Settings > Sounds and notifications > Notification light.
Possible solutions:
Here's a solution suggested by an XDA forum member: delete all notifications, turn off the screen and make sure the indicator works. Then turn the screen back on, go to the clock menu and turn off the alarm. Turn off the screen again. The light should go out, after which you can return to the clock and turn on the alarm.
Problem: Bluetooth connection is not established or is unstable
Some users are having problems when trying to connect their LG G4 to their car Bluetooth system or other devices. Also, during data transfer, song titles may be lost and other problems may arise.
Worth a try:
If you lose song titles, try disabling the default LG Music application. You can do this in the menu Settings > Are common > Applications, "All" tab.
Possible solutions:
- Look at the menu Settings > Are common > Smart Features > Smart Settings and make sure that no settings are interfering with Bluetooth functionality.
- Review your device or vehicle's owner's manual and make sure you follow the instructions to establish a Bluetooth connection.
- You may have reached some Bluetooth connection limit. Try removing old paired devices on the machine or accessory you are trying to connect to your smartphone.
- On G4 go to menu Settings > Networks > Bluetooth, tap the settings icon next to the device you're having trouble with and select Forget. Do the same with your car system or other accessory, then pair again.
- Try using the Bluetooth Auto Connect app.
Problem: Wi-Fi does not connect or is very slow
Many LG G4 users put a lot of effort into trying to establish a stable connection with Wi-Fi networks. In some cases, the phone does not connect to Wi-Fi hotspots at all, but most often the connection is established and periodically interrupted, and the data transfer speed is very low
Possible solutions:
- It's always worth starting with the simplest solution: turn off and then turn on your router and phone.
- Now go to the menu Settings > WiFi, find the network you are trying to connect to in the list, click on it and after the menu appears, select “Forget”.
- Look at the menu Settings > Are common> and check that the power saving mode settings do not interfere with Wi-Fi operation.
- Look at the menu Settings > Are common > Smart Features > Smart Settings and make sure that no settings are interfering with Wi-Fi.
- If you connect to networks in the 2.4 GHz band, then try connecting to the 5 GHz band, and vice versa.
- Check how busy your Wi-Fi channels are, this can be done using the application Wifi Analyzer. You may need to switch to a less busy channel.
- Make sure your router has the latest software.
Problem: Flipping portrait photos
If you've noticed that portrait photos change orientation to landscape (horizontal) when uploaded to websites or transferred to other devices, you're not alone - it's due to the way the LG G4 rotates photos. To rotate photos, the phone uses EXIF (exchangeable image file format) settings, which can reduce processing time, and you have two ways to deal with this problem.
Worth a try:
- Try using a different photo app. IN Play Store huge selection such applications.
- Try another file viewing application. For example, saving photos in QuickPic Gallery and then loading them from there, there will be no problem with rotation.
- You can rotate photos on your computer using any standard editor.
Problem: Green dot in photos.
Many LG G4 owners complain about strange green dots that appear in photos taken with their smartphone. Users have also complained about a pink tint appearing in poorly lit photos, but it is not yet known whether these two problems are related. There is also debate about whether the source of the problem is hardware or software.
Worth a try:
Try taking a few pictures using a different app and see if that solves the problem.
Possible solutions:
- Make sure there is no protective film, and remove the case if you are using it.
- Some users claim that clearing the cache and app data helps temporarily. This can be done in the menu Settings > Are common > Applications > Camera.
- If this is still possible, then you should contact the service center or the seller for a replacement product.
Problem: Slow Charging
Many LG G4 owners complain that their smartphone takes a long time to charge. Sometimes charging takes too long and the reason is unclear. If you notice that your phone charges slowly only under certain circumstances, then Additional information You can get information about what happens during charging using the Ampere app.
Worth a try:
- The LG G4 will charge much faster if you turn off the screen and refrain from using your smartphone while it charges.
- Some users have noticed that the charging speed directly depends on the heating of the device. Remove the case from your device if you are using it and charge it in a cool place.
- Other owners have noticed that the smartphone charges faster with the SD card removed. It might be worth trying this too.
Possible solutions:
LG G4 supports Quick Charge 2.0, but the charger that comes with the smartphone does not support it. We usually recommend using chargers and cables that come in the original kit with the phone, but in in this case is not the best option. Perhaps for fast charging device, you will need to buy a QC2.0 charger.
Problem: overheating
The Snapdragon 810 processor, which is used in the LG G Flex 2, made a lot of noise due to its tendency to overheat, so the company decided to use the 808th processor in the G4 model (while LG denied that their choice was related to the overheating problem). In any case, G4 owners also encountered this problem. But there is good news: the phone will not heat up so much as to cause serious damage, at the right moment you will see a message on the screen that your phone needs to cool down, so you can lower the screen brightness or remove it from the charger in time.
Worth a try:
- Remove the case to help the phone cool down.
- Try not to use your phone in areas with high temperatures, and do not leave it in direct sunlight.
- Do not use it while charging.
Possible solutions:
- Start by rebooting your smartphone and see if anything changes.
- There is a possibility that the problem is caused by some application. Go to menu Settings > General > Data storage, click on “Saved data” and delete it.
- You can also try removing problematic applications. To find them, go to the menu Settings > Battery and Energy Saving > Battery usage and see if there are applications there that are consuming more energy than they should be.
- The last solution is a factory reset. First, back up all the necessary files, and then go to the menu Settings > Backup and reset > Reset. Click Reset Settings. When the process is completed, do not restore all applications, but do it selectively and immediately monitor for problems.
Problem: Screen splits in half
Some users have reported that their phone screen splits vertically in half, with one part remaining the same and the other changing when the user tries to scroll the screen. The two parts are independent of each other.
Possible solutions:
- A reboot may temporarily solve the problem.
