Latest known WhatsApp problems on LG K3 (2017)
1
Why am I not getting any WhatsApp notifications on my LG K3 (2017)?
First open WhatsApp itself, tap the menu, then Settings, Notifications, and confirm that Message and Group notifications are enabled with a tone selected. Then in the phone go to Settings, Apps, WhatsApp, Notifications and make sure 'Block all' is turned off so the app is allowed to alert you. The LG K3 runs Android 6.0, where an app update can leave these toggles off. See how others solved this on Reddit

Why do WhatsApp messages arrive late or only when I open the app on my LG K3?
Delayed notifications on the LG K3 are usually Android's Doze and battery optimization pausing WhatsApp in the background. Go to Settings, Battery, tap the menu and choose Battery optimization, switch the list to All apps, find WhatsApp and set it to 'Don't optimize'. Keeping mobile data or Wi-Fi on while the screen is off also helps messages push in real time. See how others solved this on Reddit
3
My WhatsApp notifications are silent with no sound on the LG K3 — how do I fix it?
On Android 6.0 the sound is controlled inside WhatsApp, not by a system channel. Open WhatsApp, tap the menu, Settings, Notifications, and under Messages re-pick a Notification tone and make sure Vibrate is set; do the same under Group notifications. Then check that the phone is not in silent or priority-only mode in the volume and Do Not Disturb settings. See how others solved this on Reddit

Why don't WhatsApp calls show on my LG K3 lock screen?
Incoming-call display needs the right permissions. Go to Settings, Apps, WhatsApp, tap Permissions and allow everything WhatsApp asks for, then in Settings, Sound & notification, App notifications, WhatsApp, make sure notifications are not blocked and are allowed to show on the lock screen. Also confirm the phone is not in Do Not Disturb, which can suppress the call alert. See how others solved this on Reddit
5
WhatsApp notifications still stop working on my LG K3 even after checking settings — what else can I try?
If notifications keep failing, make sure WhatsApp can use data in the background: go to Settings, Data usage, WhatsApp and confirm 'Restrict background data' is off, and disable any Data saver. Then clear the app cache under Settings, Apps, WhatsApp, Storage, Clear cache. As a last step update or reinstall WhatsApp from the Play Store, since the K3's older Android can drop the push connection until the app is refreshed. See how others solved this on Reddit

How to install WhatsApp on LG K3 (2017)
1
Choose how to download
On your LG K3 (2017) you can get the official app two ways: from the Google Play Store — the easiest option, since it keeps WhatsApp updated automatically — or directly from the official website. You can download an APK file, by clicking a link “Download WhatsApp directly”.
2
Open WhatsApp
Launch WhatsApp from your home screen or app drawer and accept the Terms of Service to start setup.
3
Verify your phone number
Enter your phone number. If your LG K3 (2017) uses dual SIM, pick the line you want WhatsApp tied to, then enter the 6-digit code it sends by SMS — it usually fills in automatically.
4
Restore chats and finish setup
Restore your chat history from Google Drive (use the same Google account), add your name and photo, and tap Allow for notifications so messages and calls arrive reliably.
Stay safe: only ever install WhatsApp from the official Android source. The Download button above already points there — modified copies (GB/Plus/Aero WhatsApp) can get your number banned.
