Playing mobile phones is generally 4G, what if it becomes 3G when it comes to playing games

If the phone has an unstable or bad signal, Samsung phones generally recommend the following steps to troubleshoot and deal with it:

1.It may be that the signal coverage of your location is not good, it is recommended to restart your phone or try it in a different location.

2.Connect your phone to a wireless network to update your device to the latest version.

3.If it doesn't work, please turn it off, take out the SIM card, and try to reinsert it.

If the problem still exists after the above operation, it is recommended that you bring the purchase invoice, three-guarantee voucher and mobile phone to the local service center for testing by the engineer.

Hello, you can try the following methods.

2. Replace the ** card, the network frequency band received by the ** card of different operators is different, such as: the 4G signal of the Unicom card is stronger than that of the mobile card at the location, the network speed of the Unicom card will be faster than that of the mobile card;

3. Go to mobile phone settings - mobile network - access point - change access point to try;

4. Replace the stable network environment or replace the time period (avoid being in a closed room, surrounded by tall buildings, poor network signal coverage, etc.);

5. At the same time, you can also compare other models with the same SIM card to see if this phenomenon occurs.

7. Enter System Manager Power Saving Management Select Normal Power Saving Click the gear in the upper right corner to turn off the smart sleep power saving and then observe; Change to another geographic location or SIM card before operating

There are two reasons why the mobile phone was originally 4G and suddenly became 3G:

1. Mobile phone settings.

Since our mobile phone is set to 3G mode, the signal of the mobile phone has become a 3G network.

Second, the local 4G network signal problem.

Due to the poor local 4G network signal, the coverage is not comprehensive. Causing the phone's signal to become a 3G network.

Summary. 1. It may be due to the current signal coverage or the use of the network by many people. This situation is relatively common, you can try to turn on the [Airplane Mode] of the mobile phone and wait until the mobile network is turned off, and then turn off the airplane mode to let the mobile phone search the network again;

2. If you don't want to fall back to the 3G network, take Android phones as an example, you can select the SIM card you need to set in the [Settings] - [Dual SIM and Mobile Network] settings, and then click to enter the [Network Type Options] and select [4G Network Priority];

3. Either check whether there are [security settings] on your phone, or install an app with traffic reminders, and after exceeding the currently set ** traffic, the app and settings will automatically cut off the traffic for you. We can try to turn off the traffic limit or increase the level of the traffic limit.

How to turn off data throttling.

There's no traffic management.

If your phone doesn't have this setting on its own, you'll have to manually turn off the data. It needs to be reopened.

The software running in the background should be turned off. Save data.

Mobile phones have always been 3G for a reason:

1. The 4G Xinnai number at the location is not covered, only the 3G signal is covered. So, the phone can only use 3G signal.

2. Change the mobile phone network type setting. If the mobile phone network type is set to only use the 3G model, then the mobile phone will turn off the 4G Internet access, and only the old people will use 3G to access the Internet. In this case, you can detach it to change the network type in the phone settings and change it to 4G priority.

4G Internet access can be restored.

3. The mobile phone system is abnormal. In this case, you can restart your phone.

3G (3rd-generation) refers to cellular mobile communication technology that supports high-speed data transmission, and is the third generation of mobile communication technology. Its rate is generally more than a few hundred kbps, and it can transmit sound and data information at the same time. At present, there are 3 standards for 3G:

CDMA2000, WCDMA, TD-SCDMA, the mainstream of the industry is CDMA technology. In May 2000, the International Telecommunication Union (ITU) determined the three mainstream radio interface standards of WCDMA, CDMA2000 and TD-SCDMA, which were written into the 3G technical guidance document "Mobile International Plan 2000" (referred to as IMT-2000). In 2007, WiMAX was also accepted as one of the 3G standards.
