Unofficial Telegram client for Android with a few things the official one is missing.

---

Features

TG WS Proxy	Built-in proxy that reaches Telegram over WebSocket, the way the web version does. Works on networks that block Telegram, no VPN or server needed. Falls back to Cloudflare when even that is blocked.
Proxy names	Give any proxy a name instead of staring at IP addresses.
ID and data center	User, group and channel profiles show the ID and DC. Tap to copy.
Seconds in time	Optional 14:05:37 under messages.
Hide your number	Keeps your phone number off Settings and your profile when you share the screen.
Bottom tabs	Hide Contacts, Settings/Calls or Profile. Chats always stays.
No dead ends	Features that can't work in a fork (Play purchases, passkeys, Android Auto, Wear OS, Chromecast) are switched off or removed instead of failing.

All of it lives in Settings > dumGram.

Download

Grab an APK from Releases or the latest build:

APK	For
arm64-v8a	almost every phone from the last years
armeabi-v7a	old 32-bit phones
x86_64, x86	emulators and Chromebooks
universal	not sure? this one runs everywhere, it's just bigger

dumGram installs next to the official Telegram, they don't conflict.

Building

1. Clone with submodules:

   git clone https://github.com/damnurmum/dumGram.git
   cd dumGram
   git submodule update --init --recursive

2. Get your own api_id and api_hash at my.telegram.org and set APP_ID / APP_HASH in ~/.gradle/gradle.properties (keeps them out of git) or in gradle.properties.
3. Replace TMessagesProj/config/release.keystore with your own keystore and update RELEASE_KEY_PASSWORD, RELEASE_KEY_ALIAS, RELEASE_STORE_PASSWORD in gradle.properties.
4. For push notifications, create your own Firebase project and replace TMessagesProj_App/google-services.json.
5. Build:

   ./gradlew :TMessagesProj_App:assembleAfatRelease

   APKs land in TMessagesProj_App/build/outputs/apk/afat/release/ as dumGram-<version>-<abi>.apk.

The TG WS Proxy core ships prebuilt in TMessagesProj/src/main/jniLibs. To rebuild it you need Rust and the NDK: TMessagesProj/jni/prebuild/build_tg_ws_proxy.sh.

CI and releases

build.yml builds and checks the APKs on every push to main and every PR. Pushing a v* tag also publishes a GitHub Release with the APKs attached.

Repository secrets (Settings > Secrets and variables > Actions):

Secret	Value
APP_ID, APP_HASH	from my.telegram.org
KEYSTORE_BASE64	base64 -i release.keystore (required for releases)
KEYSTORE_PASSWORD, KEY_ALIAS, KEY_PASSWORD	keystore credentials

Syncing with upstream Telegram

git remote add upstream https://github.com/DrKLO/Telegram.git   # once
git fetch upstream && git merge upstream/master
