Hi rahulozair44 Good day What's your phone’s firmware version (Settings > About > Software information > Build number) Please check it in safe mode. (https://www.asus.com/support/faq/1005163) Does this problem appear when you in other different location? Please try to use other different sim card for a check if possible. Thank you:)

Di HP zenfone 3 max zc520tl saya juga demikian, setelah update ke versi oreo malah sinyal lemah/tidak stabil. Saya juga lakukan menurut saran yang saya baca disini tapi belum kunjung sinyal bagus, tolong dibantu permasalahan saya ini. Terima kasih.
