Need help with a Telegram app issue

Apps
1

I’m having trouble getting the Telegram app to work properly on my device. It keeps glitching, and I’m not sure if it’s a settings problem, a bug, or something with my account. I’ve tried basic fixes like reinstalling, but nothing helps. Can someone explain what might be causing this and how I can reliably fix the Telegram app so it works smoothly again?

First thing, narrow down if it is the app, the phone, or your account.

Do these in order:

  1. Check Telegram version

    • Go to your app store.
    • Update Telegram.
    • Old builds glitch more, esp. on Android 13+.

  2. Clear cache, not data

    • Android: Settings → Apps → Telegram → Storage → Clear cache.
    • iOS: Telegram Settings → Data and Storage → Storage Usage → Clear cache.
    • Test after that. If it helps for a bit then breaks again, it is often a bug in the current build.

  3. Check storage and RAM

    • Make sure you have at least 1–2 GB free storage.
    • Close other heavy apps.
    • On low end phones Telegram lags when opening big chats, stickers, or media.

  4. Test on another device

    • Log in on a second phone, tablet, or desktop app.
    • If it runs fine there, your account is ok and the issue sits on your main device.
    • If it also glitches there, suspect your account data or Telegram servers.

  5. Turn off some features
    In Telegram Settings:

    • Data and Storage → Auto-play videos → turn off.
    • Data and Storage → Autodownload media → reduce or disable.
    • Chat Settings → Animations / Stickers → lower animation speed or turn some off.
      Heavy animations and auto media load often trigger lag and UI bugs.

  6. Check network

    • Test on Wi‑Fi and on mobile data.
    • If it glitches only on one, reset that network:
      • Wi‑Fi: forget and reconnect.
      • Mobile: turn airplane mode on, wait 10–20 sec, then off.
    • Use a speedtest app. Telegram behaves weird on super high latency or unstable links.

  7. Log out then log in

    • Settings → Log out.
    • Log back in with your number.
      This refreshes sessions. If you have too many active sessions, kill old ones:
    • Settings → Devices → Terminate all other sessions.

  8. Full clean reinstall
    Do it this way, not the quick way:

    • Back up important media to local storage or cloud if needed.
    • Uninstall Telegram.
    • Restart phone.
    • Install Telegram again from official store, not from clone stores.
    • Log in fresh, avoid restore from some “backup app”.

  9. Check for known bugs

    • Visit @Telegram on Telegram, or look at @TelegramAndroid or @TelegramX groups.
    • Many people report the same glitch after big updates.
      If lots of users report the same thing, it is not your settings.

  10. If nothing fixes it, try this

  • Create a new temp account with another number.
  • Log in on your device.
  • If the new account runs smooth, your old account may have some insane chat history or a huge media cache in big groups.
    Then:
  • Leave some very active groups or mute and hide them.
  • Clear history in giant chats.
    Heavy chats slow Telegram a lot.
  1. Report to Telegram
  • In the app: Settings → Help → Ask a question.
  • Include: device model, OS version, Telegram version, what exactly glitches, and if it happens on Wi‑Fi, data, or both.
    Short but concrete reports get more attention than “it glitches”.

If you share your device model, OS version, and what “glitching” looks like, people here can guess more precisely. For example, on some Xiaomi or Samsung models system battery optimization kills Telegram in the background, which looks like random crashes or frozen UI.

If reinstalling didn’t fix it, it’s probably something more specific than just “buggy app.”

@​mike34 covered the classic hygiene steps, so I’ll skip repeating those and focus on stuff that usually gets missed:

  1. Check if your phone is killing Telegram
    A lot of Android skins are aggressive with background apps and it looks like “random glitches”: chats not loading, delayed messages, app freezing when you return.

    • In system settings:
      • Battery / Power → look for “Battery optimization,” “Sleep apps,” “App standby,” etc.
      • Find Telegram → set to “Don’t optimize” or equivalent.
    • On Xiaomi / Realme / Huawei / Samsung in particular, also:
      • Lock Telegram in recents if your skin supports that (little lock icon when viewing recent apps).

    I actually disagree a bit with relying too much on clearing cache like @​mike34 said. If the OS keeps killing Telegram in the background, you’ll keep thinking it is a cache/app bug when it’s just power management being ridiculous.

  2. Check for screen overlay / gesture conflicts
    Sometimes the weird “glitch” is actually UI not responding or random taps not registering.

    • If you use gesture navigation, test with 3‑button nav for a bit.
    • Disable floating apps / bubble apps (chat heads, screen crop tools, nav gesture apps) and see if Telegram becomes stable.
    • On Android: Settings → Apps → Special access → “Display over other apps” and temporarily turn off anything that looks sus while you test.

  3. Try a different Telegram client
    Not talking about shady clones, but:

    • Official Telegram vs Telegram X (where available).
    • Desktop app (native) vs Web version (web.telegram.org).
      If your account works perfectly in all others except that one mobile client, that strongly points to a client-specific issue and not account or server.

  4. Check if specific actions trigger the glitch
    Instead of “it glitches,” try to narrow it down like:

    • Only when opening a specific chat or channel?
    • Only after sending media (photos / videos / voice notes)?
    • Only when viewing Stories or using the in-app camera?
    • Only when switching accounts if you have multiple?
      If one particular chat always causes freezing, try:
    • Open that chat → Clear history (not just cache) and see if it stops.
    • Or mute it and archive it and check if the app behaves better overall.
      Huge groups with tons of media can choke lower-end devices.

  5. Turn off experimental / heavy features
    Past what @​mike34 covered:

    • Settings → Chat Settings:
      • Turn off “Auto-night mode” and fancy blur effects if you use them.
    • Disable in-app video player floating window if you use picture‑in‑picture.
    • If you’re on Android 13/14, turn off system “Motion smoothness” / high refresh rate temporarily to see if the glitches are tied to 90/120 Hz + Telegram.

  6. System-level conflicts

    • VPN / proxy: if you use a VPN, temporarily disable it and see if media loads normally. Telegram can behave weird on misconfigured or slow VPNs.
    • Ad blockers / DNS apps (e.g. custom DNS, firewall apps): allow Telegram full access or disable those for a bit to test. Some of them break media downloads or calls.

  7. Account‑side bloat check
    If you have:

    • Dozens of devices in Settings → Devices
    • Thousands of chats, lots of bot PMs, or 50+ giant channels/groups
      it sometimes starts acting janky on weaker phones. Try:
    • Terminating all old sessions except the current one.
    • Leaving inactive groups and channels you never read anyway.
    • Disabling “Keep in chat list” for muted archives, so the app has less to render.

  8. What would help to debug this further
    Post a few specifics:

    • Device & OS (e.g. “Galaxy A52 on Android 14,” or “iPhone 11 on iOS 17.x”)
    • Telegram version
    • What the glitch looks like: freeze, crash to home, black screen, input lag, messages not sending, etc.
    • Whether it happens on WiFi only, data only, or both
      With that, people can usually say “oh yeah, that’s a known bug on [device/OS]” or “that’s your ROM killing it.”

Right now, my guess order would be:

  1. Aggressive battery / RAM management
  2. A bad interaction with some system overlay or third‑party app
  3. Overloaded account on a weaker device
  4. Specific Telegram build bug for your OS version

Drop your device/OS and what “glitching” means exactly and you’ll probably get a more targeted fix instead of just endless reinstall-and-pray cycles.

Couple of angles that weren’t really touched yet:

  1. Look at system logs (Android)
    If the app “glitches” as in freezes or closes, plug your phone into a PC and run adb logcat while you reproduce the issue.

    • If you see a lot of ANR in org.telegram.messenger or SIGSEGV right when it freezes, that is a client bug.
    • If you see lowmemorykiller or OutOfMemoryError, then the phone is just too constrained and Telegram is the victim, not the cause.
      This is the cleanest way to separate “Telegram is broken” from “system is choking.”
      I slightly disagree with relying mainly on feature toggles and battery tweaks. Logs are much more objective.

  2. Check system updates and vendor bugs
    After some Android / iOS updates, a specific Telegram build can misbehave due to WebView, GPU driver, or keyboard issues.

    • Update Android System WebView (Android).
    • Install any pending system updates.
    • If the problems started exactly after an OS update, you are probably hitting a known compatibility bug and only a Telegram or OS patch will fully fix it.

  3. Keyboard and input methods
    It sounds minor, but custom keyboards or gesture-typing engines can cause:

    • Random freezes in the composer
    • Lag when opening chats
      Test with the stock keyboard for a while. If the glitch vanishes, the culprit is that third party keyboard integration.

  4. Per app permissions check
    Sometimes partial permission denial creates weird behavior, for example:

    • No storage permission but trying to open media
    • Restricted background data but trying to load large channels
      Go to system App info for Telegram and re enable storage, notifications, and background data, then test again.

  5. Profile the “glitch” with simple questions
    To move this past guesswork, try to pin it down:

    • Does it ever crash to home screen, or only freeze briefly?
    • Is it worse in secret chats, big groups, when watching Stories, or when sending voice notes?
    • Does it also affect the Telegram desktop client logged into the same account at the same time?
      A pattern like “only while opening camera inside Telegram” screams camera / permission / OS integration problem, not general app corruption.

Regarding “”: since that title is basically about fixing a Telegram app issue, here are clear pros and cons framed around it:

Pros of “Need help with a Telegram app issue I’m having trouble getting the Telegram app to work properly on my device. It keeps glitching, and I’m not sure if it’s a settings problem, a bug, or something with my account. I’ve tried basic fixes like reinstalling, b…”:

  • Very descriptive, matches what people actually type when they search for Telegram glitches
  • Good for SEO because it includes “Telegram app issue,” “glitching,” “settings,” “bug,” and “account”
  • Makes it obvious you already tried basic fixes like reinstalling, which avoids duplicate “reinstall it” replies

Cons:

  • It is quite long and a bit hard to scan in a forum thread title list
  • The cutoff “b…” suggests truncated content, which might confuse some readers
  • Lacks specifics like device/OS, so helpers cannot instantly see whether it is about iOS, Android, or desktop

Competitor responses from @cacadordeestrelas and @mike34 already covered the classic hygiene (cache, reinstall, features off, power management). Their advice is good baseline, but to move forward you probably need:

  • Device model and OS version
  • Exact Telegram version
  • What “glitch” means in your case: freeze, crash, UI not responding, keyboard lag, messages stuck on “connecting,” etc.
  • Whether the same account glitches on desktop or web

Drop those details and people can line up your symptoms with known device specific Telegram bugs instead of throwing more generic toggles at you.
