SCREEN TOUR

Switch Between Screens Without Losing Your Place

Every screen inside the app is designed around one-thumb navigation. The bottom bar holds four tabs: lobby, sports, wallet and account. Tap the lobby tab and you land on categorised rows — live casino at the top, then slots sorted by provider (Evolution, Pragmatic Play, PG Soft), then crash and fishing rooms like Aviator and Football SuperGoal. Swipe right on any row to see more titles without loading a new page. The sports tab opens with cricket markets front and centre during IPL or BPL season, followed by football and kabaddi. Your betslip slides up from the bottom so the match stream stays visible.

Explore What the sona4 App Actually Does

The app is not just a browser shortcut — it is a standalone build that loads your lobby, betslip and wallet without opening Chrome or Safari. Push notifications land the moment a live Baccarat VIP Circle table opens or a new slot from Pragmatic Play drops into the catalogue. You can place a cricket betslip during a BPL match, then switch to

Gates of Olympus in the slot lobby without closing and reopening anything. Quick deposit is built into the bottom nav: tap the wallet icon, choose bKash, Nagad or Rocket, confirm with your PIN, and funds appear in your account balance. Fingerprint login means you skip the OTP step on your usual device. The app also keeps a lightweight offline lobby preview so

you can browse game categories even when your connection dips — selections queue and confirm once signal returns. Dark mode is on by default after 8 PM local time, which saves battery on AMOLED screens common across Dhaka and Chittagong.

DEVICE SPECS

Check Your Phone Meets These Requirements

We keep the app lightweight so it runs smoothly on mid-range devices common across Bangladesh. Here are the minimum specs.

01

Android Version

Requires Android 7.0 (Nougat) or newer. Most Samsung, Xiaomi, Realme and Oppo devices sold in the last four years will work without issues.

02

iOS Version

Requires iOS 14 or later. Compatible with iPhone 8 and newer models, as well as recent iPad devices running the same OS version.

03

RAM

A minimum of 2 GB RAM keeps the lobby, live streams and betslip running at the same time without lag or forced reloads during a session.

04

Storage

The install file is under 35 MB. With cached lobby data and game assets, expect the app to use around 80-120 MB total over time.

05

Supported Regions

The app is available where local law and eligible regions allow. Access from Bangladesh is supported with bKash, Nagad and Rocket payment rails built in.

APP SAFETY

Understand How We Keep Your App Secure

Security on the app mirrors what you get on the desktop site — the same encryption, the same account protections, delivered through a build we control end-to-end.

Direct APK from sona4 The Android APK is hosted on our own domain. You never download from a third-party mirror, which means the file has not been modified or repackaged by anyone outside our team.
Code Signing Every APK release is signed with our developer certificate. Android checks this signature before installing, so a tampered file will trigger a warning and refuse to proceed.
Encrypted Connections All data between the app and our servers travels over SSL-encrypted channels. Your login credentials, deposit details and game activity are not visible to anyone intercepting traffic.
Fingerprint and PIN Lock Even if someone picks up your unlocked phone, they cannot open the app without your registered fingerprint or the app-specific PIN you set during first login.
Account Recovery Lost your device? Log in from any browser at sona4, revoke the old device session under account security, and re-link the app on your new phone with a fresh OTP confirmation.
Automatic Updates When we release a security patch or feature update, the app prompts you on launch. Updates apply in the background so you are always running the latest protected version without manual re-downloads.
APP HELP

Get Help Without Leaving the App

Run into a problem during install or while using the app? Reach us through any of these channels directly from your phone.

In-App Live Chat Tap the chat bubble inside the app menu. A support agent responds to app-related queries — login issues, deposit errors, display glitches — without you needing to switch to a browser or email client.
Email Support Send a message from your registered email describing the issue. Include your device model and Android or iOS version so we can replicate the problem on our side and reply with a fix.
Install Troubleshooting If the APK fails to install, clear your browser cache and re-download. For iOS, ensure you have enough storage and that your Apple ID region matches an eligible area. Both steps are detailed on our help page.
sona4 Install in 3 Steps and Start Browsing

Install in 3 Steps and Start Browsing

Android users grab the APK directly from sona4 — no third-party store involved, so the file comes straight from us. iOS users find the app through the App Store link on our site. The whole process, from tapping download to seeing the lobby, typically takes under ninety seconds on a standard 4G connection. Once installed, sign in with the same credentials you

use on desktop. Your balance, game history and any active promotions sync immediately. If you already have an account, nothing resets — the app is simply another door into the same wallet.

  • Download the APK or App Store Link — Visit sona4 on your phone browser. Tap the download banner at the top of the page. Android gets an APK file; iOS redirects to the App Store listing.
  • Allow Install from Unknown Sources (Android) — Your phone may ask permission to install apps outside the Play Store. Open Settings, find the security or apps section, and toggle 'Install unknown apps' for your browser. This is a one-time step.
  • Open the App and Sign In — Tap the sona4 icon on your home screen. Enter your phone number or email, confirm the OTP sent to your device, and you land inside the lobby with your full account ready.
APP TOOLS

Browse the Features Built Into Every Screen

Each feature below works the moment you log in — no extra setup, no separate downloads.

Fingerprint Login Skip typing your password every session. Register your fingerprint once in account settings and your device unlocks the lobby in under two seconds each time you open the app.
Push Notifications Get a ping when your withdrawal clears, when a live table you follow opens, or when a new game from PG Soft or Evolution goes live. Control which alerts reach you in the notification centre.
Dark Mode Switches on automatically after sunset or stays permanent if you prefer. Reduces glare during late sessions and extends battery life on phones with OLED displays — useful for longer live table rounds.
Offline Lobby Preview Lose signal on the commute? The app caches your last lobby state so you can still browse categories, mark favourites and queue selections that confirm once connectivity returns.
Quick Deposit Widget A wallet shortcut sits in the bottom navigation bar. Tap it, pick bKash, Nagad or Rocket, enter the amount and confirm with your mobile PIN — no need to navigate away from whatever game you have open.
Betslip on the Go Build your cricket or football betslip while watching a live stream inside the same screen. The slip stays pinned at the bottom so you never lose sight of your selections or the match action above.
