LG G3: Il segnale wifi è molto debole

Mon, 19 Mar 2018 03:28:57 -0700

Dopo aver smontato lo smartphone per riparare il motore della vibrazione ho notato un calo impressionante nel segnale wifi.

a distanza di 4 cm dal router il telefono ha 3 tacche su 4, a 2 m dal router 2 tacche, a 3 metri 1 e dopo 6 metri niente.

Non so cosa potrei avere toccato, e cercando varie guide su internet non ho ancora capito quale sia l'antenna del wi-fi.

un'altra cosa che ho notato è un calo di potenza anche nel bluetooth.

La domanda è: che pezzo va sostituito? La protezione dove ci sono le antenne, l'antenna interna, il cavetto coassiale o tutta la scheda madre?

LG G3: istruzioni per la sostituzione del touch screen su LG G3

Mon, 19 Mar 2018 03:22:41 -0700

Un buongiorno alla comunità.

Ho un LG G3 modello D855 e ho il touch che non mi funziona più ( rotto) e volevo sostituirlo. Il problema è che non volevo comprare un touch+display assemblato e conservare il mio display ( originale).

Le domande sono due: può essere sostituito solo il touch? Esiste una valida guida?

Grazie in anticipo per le eventuali risposte.

A hello to the community .

I have an LG G3 D855 model, and I have the touch that does not work me ( broke) and I wanted to replace it . The problem is that I did not buy a touch + assembled display and store my display ( original) .

The questions are two : it can only be replaced the touch ? Is there a valid driver ?

Thanks in advance for any replies .

Salve, ho un LG G3 S ed ho provato ad effettuare il ripristino dati di fabbrica con la combinazione dei tasti accensione e volume. dopo essersi riacceso, lo schermo rimane nero e compaiono solo i simboli indietro, home e multitasking e la barra di notifiche in alto, perciò non posso entrare nelle applicazioni

LG G3: demigod crash handler kernel crash..

Tue, 25 Oct 2022 04:26:16 -0700

My lg g3 phone goes to a blue screen.. Then turns off. It will then come up with a green screen and a kernal crash.. It gives instructions to reboot.. But that doesn't work! Did a hard reboot which worked for a few hours then it happens again!! My Sprint carrier said "too bad" cause I don't have insurance.. Help!! I don't want to spend the $350 they said it will cost me... I think the software update my phone last had was corrupt! Or did not finish properly!! I am at a loss.. Now it says this error..

LG G3: Phone gets stuck on LG logo start up screen and flashes repeatedly?

Fri, 29 Aug 2025 18:18:55 -0700

My LG G3 switched off by itself and the battery was at 50%. It now will not switch on. The LG logo start up screen comes on for a second then it goes black and does this repeatedly. The same thing happens when i charge it. The charging icon appears and then flashes on and off. I am not concerned about the phone. What I do want to know it how can I retrieve my photos?

LG G3: Microphone stopped working when making calls, hands free works?

Fri, 14 Apr 2017 00:38:56 -0700

When I make a call on my LG G3 the person on the other end hears me either in a muffled voice or not at all, when I make a call on speaker phone the other person hears me perfectly. I have tested this by making calls to many different people with the same result each and every time, so it is microphone related. I spoke to Verizon and they agreed saying the the the regular phone microphone and the hands free microphone are 2 separate microphones. They offered to replace the phone under warranty, however that means I would be getting a re-built unit and will have lost the 40+ hours I have spent to customize my phone. When I stopped into a Verizon store they "blew out the microphone" just to certain there was not any dirt in it, any ideas on what I might do to correct the problem?

Thank you
