First of all, I couldn't detect any of my wireless connection while my other devices are able to connect the wireless. I tried to restart phone and router and also scanned through phone, but I couldn't get my wireless signal at all. Second, I using papago x5 for y navigation apps. I tried to switched on the application and stand open air trying so hard to get my GPS signals. But the signal notification on the application just keep blinking as it is searching so long. I switched on "Use GPS Satelites" at location setting but couldn't find any f the signals too! That's the problem i find that my phone's signal is definitely BAD! Any solutions from users? Please i needed assistance desperately. Thanks!
