4G LTE Only Mode Switch app helps you to find and search for 4g LTE signal. Once you locked to 4G Mode, no other 2g/3g signals won't be catch by your phone.
This app is very helpful if your device don't have a "4G Only" Mode in phone settings.
This app was developed to be *very* similar to another app available on Play which I was using for a long time - however that particular app recently became 'updated' with very intrusive dangerous spyware & 'rating' nag screens. This is designed to perform exactly the same function while leaving out the security risks.
