Sonim XP7 User Manual

One of the cures for this is to take the battery out for a minute. Then put it back in. Sometimes this doesn't work the first time. You may want to try it a couple of times if it doesn't work.

Usually a red LED light indicator means your phone needs charging. If you have charged it and still won't turn on, I suggest having your phone checked. You might have a bad battery that's why phone won't turn on.

Simply connect your Sonim XP7 to your computer using a USB cable. Once connected, check your phone for a USB notification. Tap on it and choose Media device (MTP). Now back to your computer, open My Computer and you will see another drive for your phone.

Can you check Settings > Accessibility > Talk Back. Let me know if that's it.
