How do I take a screenshot when the volume button is not working and I dont have a home button?
You can take the screenshot still. I'll tell you the most easiest way-Go to settings> notification centre and in the quick settings icon tray,add the screenshot option.That's it. Now whenever you need to take one,you need to drag down and select the screenshot option.
In my phone LTE/3G/2G is there but LTE (4G) alone is not there?
First of all, you don't have to worry about not having a LTE only mode, if you are forced to use the option - LTE/3G/2G then what will happen is-Case 1: You are on JIO 4G, it will use 4G signals wherever it gets signal because Jio operates only in 4G.Case 2: You are on Airtel/Vodafone/Idea , what will happen is if you in an area where 4G signals are available, then the phone will be connected to LTE network . If the signal strength of 3G/2G is better or only 3G or 2G is available then it will connect to whatever is giving a better connectivity.So, I am assuming that, the 4G signal strength of Airtel is not good in your home, so your phone keeps changing to 3G network and you don't want that. To use only LTE network even if the signals are low then for Android you can use these steps-Procedure 1:Step 1- Open your phone dialerStep 2- Type *#*#4636#*#*Step 3- Your phone will open Android'sEngineering Mode, then click on Phone information. If there are two phone information then 1st is for the 1st SIM and 2nd is for 2nd SIM.Step 4- Scroll down click here-Step 5- Now choose the option LTE onlyYou are done. Now use your phone at LTE only, only downside of it is it won't be able to switch to 3G/2G if there is low network strength.If the above method doesn't work, try this-Procedure 2-Step 1: Open Play Store, type MTK Engineering Mode. Download the application. Link -https://play.google.com/store/ap...Step 2: Same as Procedure 1 from Step 3.Hope this helps.
