.scss file as below:

.full-screen {
    height: 100% !important;
    width: 100% !important;
}

.headrow{
    height: 100%;
    padding-left: 20px;
    //padding-right: 55px;
    background: #2C405A;
    color: white;
}
.centerrow{
    height: 100%;
    align-content: center;
}

in browser i can see center. but in app (after compile and install in ipad) its not coming in center of the div. even i used text-center same as colum in ion-row its not working .

pls help me to find a solution.

which version of ionic you used?

here is your html code

<div class="full-screen" >
        <div style="height: 10%;width: 100%;">
            <ion-row class="headrow">
                <ion-col text-left>
                  <img src="../../assets/imgs/logo.png" height="40px" style="vertical-align: -webkit-baseline-middle;float: left;">
                  <ion-label style="padding:15px; font-size: 40px; color: #ffffff; vertical-align: -webkit-baseline-middle"><span>projectname</span> <span style="font-size: 10px;">v1.0.0</span> </ion-label>
                </ion-col>
                
                <ion-col text-right>
                  <img src="../../assets/imgs/avsoft_logo.png" height="40px" style="padding:2px; vertical-align: -webkit-baseline-middle">
                </ion-col>
              </ion-row>
          
        </div>
        <div style="height: 80%;width: 100%;">
          <ion-row style="border:2px solid #1df84d" class="centerrow">
            <ion-col text-right><img src="../../assets/imgs/tank_button.png" (click)="gotohome()"></ion-col>
            <ion-col text-center><img src="../../assets/imgs/ship_button.png"></ion-col>
            <ion-col text-left><img src="../../assets/imgs/flight_button.png"></ion-col>
          </ion-row>

        </div>
        <div style="height: 10%;width: 100%;">
            <ion-row >
            <ion-col text-right>
                www.xyz.com
            </ion-col>
            </ion-row>
          </div>

</div>

.full-screen {
        display: flex;
        width: 100%;
        height: 100%;
        flex-wrap: wrap;
        align-items: center;
        justify-content: center;
    }
    
    .headrow{
        height: 100%;
        padding-left: 20px;
        //padding-right: 55px;
        background: #2C405A;
        color: white;
    }
    .centerrow{
