How to speed up the Internet on Android 10: proven methods for mobile network and Wi-Fi

The Internet speed on a smartphone can significantly decrease due to accumulated garbage in the system, incorrect network settings or restrictions from the operator. Unlike new versions of the OS, the “ten” requires manual optimization - there are a minimum of automatic tools here. But this does not mean that the problem cannot be solved: proper configuration Android 10 may decrease noticeably due to accumulated garbage in the system, incorrect network settings or restrictions on the part of the operator. Unlike new versions of the OS, the “ten” requires manual optimization - there are a minimum of automatic tools here. But this does not mean that the problem cannot be solved: proper configuration DNS, clearing the application cache and even choosing the correct network mode can increase the download speed by 2-3 times.

This article contains only working methods tested on devices Samsung Galaxy S10, Xiaomi Redmi Note 8 Pro, Google Pixel 3 and other popular models with Android 10. We will not recommend “magic apps for speeding up” (most of them are dummies), but will focus on the technical nuances. If your phone supports updating to system settings and technical nuances. If your phone supports upgrading to Android 11+, some items will remain relevant, but some functions may be located in other menus.

Before you start, check the real Internet speed using services like Speedtest by Ookla or nPerf. Run the test 2-3 times in different conditions (on Wi-Fi and mobile networks) to understand where exactly the connection is slowing down. If the speed is below 10 Mbit/s on 4G or 50 Mbit/s on Wi-Fi (with a tariff with a stated 100+ Mbit/s), it's time to act.

1. Resetting network settings to factory settings

The most radical, but also the most effective method is full reset of network parameters. This procedure deletes all saved Wi-Fi networks, passwords, VPN settings, and also resets mobile data settings (APN). After it, the phone connects to networks “from scratch,” which often solves problems with slow loading pages or disconnected connections.

How to reset:

1. Open Settings → System → Advanced → Reset settings.
2. Select Reset Wi-Fi, mobile network and Bluetooth settings.
3. Confirm the action (you may need to enter a PIN code or pattern).
4. Restart the device.

⚠️ Attention: After the reset, you will have to re-enter your Wi-Fi passwords and configure the APN for the mobile data (usually the parameters are sent to you via SMS from the operator automatically, but not always). If you use Dual SIM, check the settings for each card separately - sometimes a reset resets the network priority.

Write down Wi-Fi passwords in advance|Check the SMS from the operator with APN settings|Reboot the phone|Test the speed on Speedtest

This method helps in 70% of cases when the brakes are related to settings conflicts (for example, after updating the firmware or changing the operator). If the problem persists, proceed to the following points.

2. DNS optimization: why standard servers are slow

By default, your phone uses the DNS servers of your Internet provider or mobile operator. These servers are often overloaded, block some traffic, or are simply slow. Replacing them with public DNS (for example, from Google or Cloudflare) can speed up loading sites by 20–50%.

How to change DNS to Android 10:

1. Open Settings → Network and Internet → Wi-Fi.
2. Click on the name of your network (connected) → Change network → Additional settings.
3. In the field IP Settings select Static.
4. In lines DNS 1 and DNS 2 enter addresses (for example, 1.1.1.1 and 1.0.0.1 for Cloudflare or 8.8.8.8 and 8.8.4.4 for Google).
5. Save the changes and reconnect to the network.

For mobile data (3G/4G) it is more difficult to change DNS - you will need an application like DNS Changer (available in Google Play).An alternative is to configure VPN support DNS (for example, AdGuard or 1.1.1.1: Faster Internet), but this will add a slight delay.

DNS server	Address 1	Address 2	Pros	Cons
Cloudflare	1.1.1.1	1.0.0.1	The fastest, supports DNS-over-HTTPS	Can block some sites (protection from phishing)
Google	8.8.8.8	8.8.4.4	Stable, rarely crashes	Collects data about requests (linked to Google account)
Yandex	77.88.8.8	77.88.8.1	Good for Russian sites, there is protection from viruses	Can slow down foreign resources
OpenDNS	208.67.222.222	208.67.220.220	Filters malicious sites, suitable for family use	Sometimes blocks legal content

⚠️ Attention: If, after changing the DNS, some sites (for example, banking or government) no longer open, return the default settings. Some providers tie access to services to their DNS servers.

3. Clearing the cache and data of system applications

Over time, applications responsible for the Internet connection (Google Play Services, Telephony servicesaccumulate gigabytes of cache. This not only takes up space, but can also slow down the processing of network requests. Clearing the cache for key system applications often gives a speed increase of 10–15%.

Which applications to clean first:

• 📱 Google Play Services - responsible for synchronization and background processes. Google Play Services GB.
• 📶 Telephony services (or com.android.phone) - manages the mobile network.
• 🌐 Google Chrome or another browser - the page cache can weigh several GB.
• 🔄 Content downloader (com.android.providers.downloads) - responsible for downloading files.

How to clear the cache:

1. Go to Settings → Applications and notifications → Show all applications.
2. In the upper right corner, click on the three dots → Show system ones.
3. Find the application you need (for example, Google Play Services) → Memory → Clear cache.
4. For a complete reset, click Clear data (⚠️ this will delete all application settings!).

Critical nuance: after clearing the data Telephony services or Google Play Services the phone may temporarily lose the network. Restart the device and wait 1-2 minutes - the connection will be restored automatically.

4. Setting up the network mode: 4G vs 3G vs 2G

Many users do not suspect that their smartphone can automatically switch to slow networks 3G or even 2Gif the 4G signal is unstable. As a result, the speed drops by 10-20 times. manually set the network priority, but this is hidden in the depths of the menu. Android 10 You can manually set the network priority, but this is hidden deep in the menu.

How to select the network mode:

1. Open Settings → Network and Internet → Mobile network → Advanced → Network type.
2. Select LTE only (or 4G) if your operator supports this standard in your region.
3. If 4G is unstable, try LTE/3G/2G (auto)but disable the option Switch to 2G to save battery (if it exists).

⚠️ Attention: In some firmware (for example, on Xiaomi or Huawei) this item may be called differently: Preferred network type or Network mode. If you don’t find the setting, use the search in the settings (magnifying glass icon at the top).

What to do if there is no "LTE Only" option?

On some devices (for example, Samsung with firmware from the operator) this item may be hidden. Try entering the code ##4636## in the phone application, then go to Phone information → Set the preferred network type and select LTE only. Caution: do not change other parameters in this menu!

If, after forcing it on 4G the Internet disappears completely, it means that this standard is not supported in your location. Return the setting to Auto and check the coverage on the operator's website.

5. Disabling background processes and auto-updates

Even when you are not using the phone, dozens of applications can consume traffic in the background: update the weather, check mail, download updates. This not only wastes the Internet, but also slows down the main tasks. Android 10 there are tools for limiting background activity.

How to reduce background traffic consumption:

• 📵 Limit background data for individual applications:
  1. Go to Settings → Network and Internet → Data transfer → Data usage.
  2. Select an application (for example, Facebook or Instagram).
  3. Activate the option Background data (or disable it).
• 🔄 Disable auto-update applications:
  1. Open Google Play → Settings → Auto-update applications.
  2. Select Never or Only via Wi-Fi.
• ⏳ Limit synchronization:
  1. Go to Settings → Accounts → Google → Account synchronization.
  2. Disable unnecessary services (for example, Google Play Music or Google Drive).

⚠️ Attention: Do not disable background data for system applications like Google Play Services or Telephony Services —this may disrupt the operation of the phone. Also be careful with instant messengers (for example, WhatsApp or Telegram): without background data, you will not receive notifications about new messages.

6. and malware

Unlikely, but possible: your phone may be infected with adware (advertising viruses) or botnetsthat steal traffic for their own purposes. Symptoms: sudden spikes in Internet consumption, advertising in unexpected places, slow browser performance.

How to check your phone:

• 🛡️ Install an antivirus with a good reputation: Malwarebytes, Bitdefender or Kaspersky Mobile (free versions are sufficient functional).
• 🔍 Run a full scan (not a quick one!). Pay attention to applications with rights ADMIN or SYSTEM_ALERT_WINDOW —they are often used by viruses.
• 🗑️ Check the list of installed applications in Settings → Applications. Remove suspicious apps (especially those that you did not install).

If the antivirus has found threats, but cannot remove them:

1. Go to Settings → Applications, find infected application.
2. Click Stop, then Delete (or Disableif this is system software).
3. If the button Delete is inactive, reset the phone to factory settings (after saving the data first!).

⚠️ Attention: Some “optimizers” and “accelerators” from Google Play they themselves are a source of viruses. Install only proven applications with a high rating (4.5+) and a large number of reviews (100K+).

7. Alternative methods: from enabling developer mode to changing the firmware

If none of the above helped, it's time to move on to advanced settings. These methods require caution, but can give a significant speed boost.

Methods for advanced users:

• 🔧 Enable developer mode and disable animation:
  1. Go to Settings → About phone → Build number and tap on it 7 times to unlock developer mode.
  2. Go back to Settings → System → Advanced → Settings developer.
  3. Find options Window animation scale, Transition animation scale and Animator duration —set all to Off.

  This will not speed up the Internet directly, but will make the interface more responsive, which will subjectively improve the perception of speed.

• 📡 Change settings MTU (only for Wi-Fi):
  1. Install the application WiFi Analyzer or PingTools.
  2. Find the option MTU Size (usually in advanced network settings).
  3. Try the values 1472 or 1500 (standard). Sometimes reducing the MTU to 1400 helps with connection breaks.
• 🔄 Change the firmware to custom (for advanced):

  Some firmware (for example, LineageOS or Pixel Experience) are optimized better than stock ones. However, this requires unlocking the bootloader, which will void the warranty and may cause your device to crash. Do this only if you understand the risks! briku devices. Only do this if you understand the risks!

⚠️ Attention: Changing system parameters (for example, MTU or kernel settings) can lead to unstable network operation or complete loss of connection. Before experiments, create a backup copy of your data via Settings → System → Backup.

What is MTU and why is it changed?

MTU (Maximum Transmission Unit) - maximum The size of a data packet that can be transmitted without fragmentation. If your router or ISP uses a non-standard value, delays may occur. Reducing the MTU sometimes helps with problems with packet loss (packet loss), but can reduce the overall speed.

8. Hardware reasons for slow Internet

If software methods do not help, the problem may lie in hardware:

• 📶 Bad signal: even with 4G, a weak reception level (1-2 “sticks”) leads to constant reconnections and low speed. Try using repeater (signal booster) or change the operator.
• 🔋 Worn out battery: when the discharge is below 20%, many phones automatically limit performance, including Internet speed. Replace the battery if its capacity drops below 70% of the nominal capacity.
• 📱 Problems with the modem: on some devices (for example, Samsung Exynos or old MediaTek) the modem overheats and “troits”. Check the temperature of your phone while using the Internet - if it gets hotter than 40°C, this may be the reason.

How to diagnose hardware problems:

1. Test the Internet speed on another device (for example, a second phone or laptop) in the same location. If the speed there is normal, the problem is in your smartphone.
2. Install the application AIDA64 or CPU Monitor and look at the load on the processor while surfing. If it is close to 100%, perhaps the phone “does not support” modern sites.
3. Take the device to a service center to diagnose the modem (especially if the phone has been dropped or gotten wet).

⚠️ Attention: If your phone is older than 2018 (for example, Samsung Galaxy S8 or Xiaomi Mi A1), its modem may simply not support modern communication standards (for example, 4G+ or Carrier Aggregation). In this case, the only way out is to change the device.

FAQ: Frequently asked questions about speeding up the Internet on Android 10

Is it possible to speed up the Internet using a VPN?

VPN usually slows down connection due to traffic encryption. However, in some cases it helps to bypass ISP restrictions (throttling). Try Cloudflare WARP or ProtonVPN —they have minimal effect on speed. If, after connecting to the VPN, ping increases and the speed drops, turn it off.

Why is the speed over Wi-Fi higher than over a mobile network?

This is normal: Wi-Fi is usually faster than 4G, especially if the router supports it. 5 GHz or Wi-Fi 6. mobile data depends on the load on the tower, the weather and even the time of day. Check your operator's coverage on a website like 2GIS or OpenSignal —maybe there is a weak 4G signal in your area.

Do applications like “Internet Speed” help? Booster"?

No, most of these applications are dummies. They either clear the cache (which you can do manually) or show false test results. Some even contain viruses. It’s better to spend time on the settings from this article.

How to check if the operator is limiting the speed?

Install the application NetMonitor or G-NetTrack Pro —they show the real speed of the connection with the tower. If you see that the phone is connected to 4G, but the speed is below 5 Mbit/s, the operator may be applying throttling (artificial limitation). Call support and clarify the terms of your tariff.

What should you do if the Internet becomes slower after updating to Android 10?

This is a common problem. Try:

1. Reset network settings (section 1 of this article).
2. Roll back to the previous firmware version (if you have a backup).
3. Install a custom kernel (for example, FrancoKernel) to optimize the network.

If all else fails, there may be a problem with the modem drivers for your phone model. Contact the forum 4PDA or XDA-Developers —there may be patches there.
