Main Causes of Slow Internet Speed on Android
Before fixing the problem, it’s important to understand why it happens.
- Weak Network Signal: Low signal strength reduces internet speed, especially in closed rooms or rural areas.
- Network Congestion: Too many users on the same network can slow down your connection.
- Background Apps Using Data: Some apps use internet silently in the background.
- Outdated Software: Old Android versions may have network bugs.
- Cache and Junk Files: Excess cache can slow system performance and internet.
- VPN Interference: VPNs often reduce speed.
- Wrong Network Settings: Incorrect APN or DNS settings affect performance.
- ISP Throttling: Some providers limit speed after data usage.
Solution 1: Check Your Network Signal Strength
First, check your signal bars.
What to do:
- Move router near windows
- Go to open space
- Avoid basements
- Switch to better location
Better signal = better speed.
Solution 2: Turn Airplane Mode On and Off
This refreshes your network connection.
Steps:
- Enable Airplane Mode
- Wait 20 seconds
- Disable it
- Turn data/Wi-Fi back on
This often improves speed instantly.

Solution 3: Restart Your Phone
Restarting clears temporary bugs.

Do this at least once a week.

Solution 4: Close Background Apps
Some apps consume data secretly.
Steps:

Solution 5: Clear Cache and Junk Files
Cache buildup slows performance.
Steps:
- Settings → Storage

Avoid unknown cleaner apps.
Solution 6: Check Data Usage and Limits
Your speed may be reduced after limit.
Steps:
- Settings → Connection → Data usage
- Billing cycle and data warning
- Disable data limit
Contact ISP if speed is capped.

Solution 7: Disable VPN and Proxy
VPNs route traffic through servers, slowing speed.
Steps:
- Turn off VPN app
- Remove proxy in Wi-Fi settings
- Restart connection
Use VPN only when needed.

- Select 4G/5G manually
- Restart
Choose the strongest available network.

Solution 12: Check Wi-Fi Router Position
For Wi-Fi users:
✔ Place router in center
✔ Keep away from walls
✔ Avoid metal objects
✔ Keep elevated
Better placement = better speed.
Solution 13: Test Internet Speed
- Check if problem is real.
- Use trusted speed test apps and compare with your plan.
- If speed is far lower, contact ISP.
Solution 14: Factory Reset (Last Option)
Use only if nothing works.
⚠️ Backup data first. Factory reset removes all bugs but deletes data.
When to Contact Your Internet Provider
Contact your ISP if:
- Speed is always slow
- All devices are affected
- Data is throttled
- Network drops frequently
They can fix network-side problems.
