Note: If you have a new Galaxy S4 Mini screen assembly without the front housing, you need to heat up the screen to separate the front housing from the screen and transfer the front housing to the new screen.

    I cracked the glass on my S4 Mini GTI9192 and I bought a new Samsung Galaxy A11. I need to retrieve my contacts list from the S4Mini but of course nothing is visible on the Mini. How do I go about this as thecontacts were saved to the phone not the SIM.

      You need to connect your phone to computer and transmit the original data to files. After that, you can save your contact list to your new phone.

    Fitted a new screen without an issue. Charging board, SIM/SD card tray was hard to take out as it is fixed with double sided tape. Great guide that convinced me not to spend money on a new phone.

    Awesome guide! Maybe mention that the Charging Port as well as the Sim Card tray are glued down. It takes patience and gentle, persistent force to get them loose without breaking them.

    Followed instructions I’ve never done any thing like this before and it worked a dream.

    excellent photos – worked first time – only point to mention you have to “gently” prise away charger circuit board (not port flex cable as stated) – fits in new case
    if you look in new case you will see how sim card flex is “locked” easy!!!

    I followed your tutorial to the letter and switched out a broken screen with an old phone I had that electronics were bad & screen good,it went “Perfectly” for me but I paid close attention to what others had mentioned and only found 2 tricky parts,gettin the back camera wire under the framework and gettin that display wire rehooked up.
    THX for GREAT “DIY” Info

    I did this, however the mainboard will not go in correctly. The ends located at the charging port and the head phone jack are almost too long. I made sure to order the correct screen, so I do not know what could be wrong.

      I’ve got the exact same problem on my galaxy 4 mini screen. Did you ever find a fix?
