4G LTE Only is a free Android application developed by PARIMAL KAVATHIYA that allows users to easily switch to a 4G network with just one click. This tool application opens a hidden settings menu where advanced network configurations can be selected, giving users the ability to force 4G or any other network type or mode.

One of the key features of 4G LTE Only is its ability to change 2G or 3G networks to 4G. This is particularly useful for users with dual SIM phones, as the app supports dual SIM functionality. Additionally, users can get information about their application usages and access hardware information and phone info.

It is important to note that not all mobile phones support the dual SIM menu, and this app may not work on every phone. Some phone brands, such as Samsung and others, may block the opportunity to force switch networks. Furthermore, the app will only work if there is a 4G network available in the user's area and if the smartphone itself supports 4G networks.

Overall, 4G LTE Only provides a convenient solution for users who want to easily switch to a 4G network and access advanced network configurations on their Android devices. However, it is important to check if the app is compatible with your specific phone model and if your area has a 4G network before using it.
