WhatsApp for LG X Skin

LG's battery saver and Smart cleaning aggressively close apps, which kills background message delivery. The reliable fix is per-app: long-press the WhatsApp icon, open App info > Battery, and set it to 'No restrictions' (older LG builds call this 'Don't optimize' or 'Battery optimization > All apps > WhatsApp > Don't optimize'). Then open Settings > Battery & power saving and turn off any Power saving mode while you need notifications. This stops the system from suspending WhatsApp so messages and calls arrive on time.

LG ships its own apps alongside Google's, which uses storage WhatsApp needs for media and chat backups. Go to Settings > Apps, tap any LG or carrier app you don't use, and choose Disable (or Uninstall if the option is offered) to free space. Before backing up, open WhatsApp > Settings > Chats > Chat backup and confirm it points to your Google account, so the backup lands in Google Drive rather than on the limited local storage.

This is a budget LG device with modest radios, so calls suffer most on weak Wi-Fi or 3G. WhatsApp calls run over your internet connection, so switch to a stable Wi-Fi network or test on mobile data to compare; if a saved Wi-Fi network is congested, go to Settings > Network & internet > Wi-Fi, forget it, and reconnect. If your audio is one-sided, open Settings > Apps > WhatsApp > Permissions and confirm Microphone is allowed. See how others solved this on Reddit

LG no longer ships Android or security updates for this model, so WhatsApp will eventually warn you and may drop support on very old OS versions. Check Settings > General > About phone > Software info to see your Android version, and keep WhatsApp itself updated through the Play Store as long as updates are offered. To stay safer in the meantime, only install apps from the Google Play Store and back up chats regularly to Google Drive so you can move to a newer phone easily. See how others solved this on Reddit

WhatsApp uses your phone's system emoji set, and the LG X Skin shows LG/Android emojis rather than Apple ones. Without root you can't replace the system emoji font, and most keyboards (including Gboard) still display the system emojis inside WhatsApp, so swapping keyboards usually won't change them. The honest options are to live with the Android set or, if you must have Apple emojis system-wide, root the device and flash an emoji font, which is risky and not recommended on this older phone.
