1) No aplicativo "Gerenciamento de Sistema" no "Gerenciador de Execução Automática" escolha desativar todos os aplicativos não utilizados/raramente utilizados.

2) Em Configurações -> Wi-Fi -> Avançadas desative o item "Busca sempre disponível". (Desative este item, somente se você não precisa verificar a localização permanente)

3) Se no local existe uma conexão 4G ou 3G ruim (constantemente muda de 4G para 3G, 3G para 2G, siga então Configurações -> Mais -> Redes móveis -> tipo de rede para escolher o tipo de rede, que obteve sinal estável (3 pontos +).

4) Não é recomendável usar aplicativos de terceiros operando com aplicativos de rastreamento de modo de economia de energia. Eles podem trabalhar constantemente em segundo plano e impedir que o telefone entre em modo de suspensão.

5) Verifique os erros nas contas de sincronização. Acesse Configurações -> Contas, escolha uma conta e depois verifique se há algum erro de sincronização. Se houver erros, tente sincronizar a conta manualmente.

Não é recomendável usar um carregador de terceiros para o seu telefone, se por qualquer motivo você precisar deste, apenas certifique-se de que as configurações eram semelhantes aos parâmetros da carga original.

Você pode reiniciar o roteador primeiro. Se o telefone ainda falhar ao localizar o ponto de acesso, obedeça as seguintes etapas:

1. Verifique se o roteador oculta o SSID. Para obter detalhes sobre a configuração no roteador, consulte o Guia do Usuário.

2. Detecte a frequência e os canais ajustados no roteador. E por favor mude o canal para melhorar a intensidade do sinal.

3. Verifique se a frequência do roteador está ajustada para 5GHz. Se sim, defina a frequência do roteador para 2.4 GHz (somente para os telefones que suportam frequência de 2.4 GHz).

4. Se as soluções anteriores não funcionarem, utilize outro telefone para verificar se os pontos de acesso podem ser digitalizados nesse telefone. Se sim, leve seu telefone para um centro de serviço autorizado da TP-Link e verifique o hardware.

1. Se o seu telefone estiver longe do roteador Wi-Fi ou estiver isolado do roteador Wi-Fi por uma parede, a intensidade do sinal fica fraca, o que resultará em uma diminuição da velocidade da rede ou na má qualidade do sinal.

2. Certifique-se de que a tampa protetora do seu telefone é feita de plástico ou couro em vez de metal, porque a capa protetora metálica bloqueia os sinais de antena do telefone.

3. Experimente diferentes canais Wi-Fi no roteador.

4. Verifique se outros dispositivos estão transmitindo tráfego intenso de dados, por exemplo, usando o laptop para baixar filmes. Se sim, organize adequadamente os recursos da rede.

5. Use o Speed Test ou software semelhante para testar a taxa Wi-Fi.

6. Conecte-se ao Wi-Fi próximo ao roteador.

1. Verifique se o fone de ouvido Bluetooth, o kit carro Bluetooth ou o alto-falante Bluetooth está no modo de emparelhamento. Para obter detalhes sobre dispositivos diferentes, consulte os manuais de usuário.

2. Verifique se o fone ou alto-falante Bluetooth tem alimentação suficiente, se encontra dentro da área de trabalho do Bluetooth (10m) e não tem obstáculos ou interferências ao redor.

3. Se o seu telefone já estiver emparelhado com outro dispositivo Bluetooth, desligue o telefone desse dispositivo.

4. Reinicie o dispositivo Bluetooth e o telefone e volte a ligar o telefone ao dispositivo Bluetooth.

5. Você também pode tentar conectar o dispositivo Bluetooth a outro telefone de uma marca diferente e verificar se o problema foi resolvido. Obtenha o modelo do dispositivo Bluetooth (para o kit de carro Bluetooth, verifique se ele precisa ser instalado com antecedência). Se o problema persistir, leve seu telefone a um centro de serviço autorizado da TP-Link para verificar o hardware e o software.

Seu telefone suporta aplicativos de terceiros somente no formato APK. Verifique se o aplicativo que você está tentando fazer o download está neste formato.

Se o aplicativo não for do app center, será necessário configurar o telefone para confiar na origem do aplicativo e depois instalar o aplicativo. Acesse Configurações > Segurança, clique em Fontes desconhecidas. Em seguida, reinstale o app.

O aplicativo de terceiros pode não ser compatível com o telefone. Tente utilizar aplicativos semelhantes.

1. Go to Settings > Storage and set the default storage location to your micro SD card.

2. Open the application that you want to download files from, and check whether you can set the storage directory for the downloaded files. If yes, set the download path to your micro SD card. For specific file paths, refer to the directories of the micro SD card in Files.

3. If the problem persists, the videos or files are not allowed to be saved in the micro SD card, which can't be controlled on your phone.

1. Go to Settings-> Battery, touch on the Menu button on the right top corner, and make sure the Battery saver is off.

2. Check whether the battery level is low. At low battery level, to extend the phone usage and protect your phone, your phone's performance is limited. You can charge your phone.

3. Check whether any download task is implementing on the background. File copying operations increase the load of the phone.

4. Check whether there is no space in the storage. If only hundreds of MB is available, open Settings->Storage to manually delete some large files.

5. Check whether the quality of the micro SD card is poor. You can remove the micro SD card or replace a micro SD card and check whether the performance is improved.

6. For online apps, check whether the phone uses data traffic or Wi-Fi network. The performance is also affected by unstable network connections.

7. Check whether your phone is powered on for a long period of time, for example, half a month. Restart your phone to check whether the performance is improved.

8. Check whether the screen is frozen and the system displays non-responded screen when the system is stuck. If yes, the app works improperly. You can update the app, use the app for a while, and find out the regularity of this problem.

9. If the problem is not caused by any of the above reasons, provide information about detailed scenarios, specific operations, app version, and probability of occurrence to TP-Link technical support engineers.

1. If the Wi-Fi hotspot is encrypted, check the password you entered is correct. Note that the password is case-sensitive.

2. Check whether the Wi-Fi hotspot name or password has been changed. If so, obtain the new information and try again.

3. Make sure you are within the working range of the Wi-Fi hotspot; otherwise the Wi-Fi connection will automatically disconnect.

4. The number of connected devices may have reached the Wi-Fi hotspot's limit. Try connecting to another available network.

5. If your phone can't connect to the Wi-Fi hotspot and keeps obtaining an IP address, set a static IP address for it as follows:

   For an encrypted Wi-Fi hotspot, on the Wi-Fi settings screen, touch the hotspot.

  In the displayed dialog box, select advanced options check box. Under IPv4 settings, touch the drop-down list box, and choose Static. Then enter the IPv4 address, Gateway, etc.

  Enter the password, and touch Connect.

Note:

The figures are for your reference only. The actual screens may vary.

Check whether the MAC address filtering function is enabled on the router. If this function is enabled, phones that are not in the access list can't access the Wi-Fi network. For details about configuration on the router, see the router User Guide.

To connect to some public Wi-Fi hotspots, you may need to log in to a web page for registration. For details, contact the Wi-Fi hotspot provider.

If the problem persists, restart Wi-Fi on your phone or restart the Wi-Fi hotspot device.

Note: It is recommended that your phone is fully charged, and back up the data, such as contacts, messages, and call logs that are on your phone before update. We suggest you use FOTA to update your device instead of local update.
