Why is my Bluetooth keeps on closing and don't connect

This likely means Bluetooth IC hardware failure (common on Tecno models) if all tries invane. You’ll need a repair center to replace the chip or mainboard.

Bluetooth turning off by itself (keeps closing), refusing to stay on, or failing to connect/pair — is fairly common on budget Tecno/Infinix phones (including Spark series). It can be caused by software glitches, aggressive battery optimization, corrupted Bluetooth cache, interference, or (less often) hardware problems like a faulty Bluetooth antenna/IC.

Here are the fixes in the order you should try them — start from the top and work down. Most people fix it with steps 1–5.

Quick & Easy Fixes First (Try These in 5 Minutes)

Toggle Bluetooth + Restart Phone

Swipe down twice → long-press Bluetooth icon → turn OFF → wait 10 seconds → turn ON.

Then restart the phone (hold power button → Restart).

Many times this alone stops the auto-closing behavior.

Forget all paired devices & re-pair

Settings → Bluetooth → tap the gear/settings icon next to each paired device → Forget/Unpair.

Turn Bluetooth off → on again.

Put your headphone/speaker/car in pairing mode → search & connect fresh.

(Old pairings can get corrupted and cause crashes/loops.)

Reset Wi-Fi, Mobile & Bluetooth settings (very effective on Tecno phones)

This resets network stuff without deleting apps/photos.

Go to Settings → System → Reset options (or search "reset" in settings).

Choose Reset Wi-Fi, mobile & Bluetooth (sometimes called "Reset network settings").

Confirm → phone will restart.

After reboot, turn Bluetooth on and try pairing again.

This clears corrupted Bluetooth cache/config — fixes ~50–60% of these issues on Spark models.

Turn OFF Battery Optimization for Bluetooth

Some Tecno phones aggressively kill Bluetooth to save battery.

Settings → Battery → Battery optimization (or App battery usage).

Look for "Bluetooth" or "Bluetooth Share" in the list.

Tap it → choose Don't optimize / No restrictions.

Also do this for any Bluetooth apps you use (e.g. music player).

Disable Wi-Fi/Bluetooth scanning in location (helps with random turning off)

Settings → Location → Location services (or Scanning).

Turn OFF Wi-Fi scanning and Bluetooth scanning.

These background scans sometimes interfere and force Bluetooth to restart/crash.

If Still Not Fixed (Next Level)

Clear Bluetooth cache & data (safe, but you'll have to re-pair everything)

Settings → Apps → See all apps → Show system apps (three-dot menu).

Search for Bluetooth → tap it → Storage & cache → Clear cache first.

If still bad → Clear storage/data (this resets Bluetooth completely).

Restart phone.

Check for software update

Settings → System → System update.

Install any available update — Tecno sometimes releases Bluetooth stability patches for Spark 10 Pro.

Safe Mode test (to see if an app is causing it)

Hold power button → long-press "Power off" → tap OK on "Reboot to safe mode".

In safe mode, try Bluetooth.

If it works normally → a third-party app is interfering (uninstall recent apps one by one).

Restart normally to exit safe mode.

When It's Probably Hardware (Rare but Happens on Spark Series)

If Bluetooth turns off instantly even after reset, or phone restarts when you try to turn it on:

Damaged Bluetooth antenna (inside, near top/bottom of phone).

Faulty Bluetooth IC or RF section (common after drops, water, overheating

The menu has disappeared from my mobile phone, and I can’t scroll up to see the text

This usually happens due to a software glitch or corrupted system component. Start by restarting your phone in Safe Mode to check if a third-party app is causing the issue. If Bluetooth works in Safe Mode, uninstall recently installed apps. Next, clear cache and data of Bluetooth and Bluetooth Share (Settings → Apps → Show system apps). Make sure your phone has the latest system update. If the problem continues, reset network settings. Persistent Bluetooth crashes with random restarts often indicate corrupted firmware or failing hardware, in which case factory reset (after backup) or service center repair is required.
