About two weeks ago, I broke the camera lens on my Galaxy S5 (Japanese docomo SC-04F). I took it to the docomo shop and got a new phone (S5#2) for only $50, but after some initial setup, I noticed the phone dropped WiFi connections, would not connect when a known WiFi spot was nearby, and the download speeds were only 5% of the still working old S5 and my other devices.
So, docomo gave me a new phone (S5#3).
The third S5 was initially fine, but after loading all my apps, the same thing has happened! And this was no problem on the original phone even though it had even more apps. I'm wondering if one of the chat apps is the culprit (Telegram, docomo mail, Inbox, LINE, messenger, WhatsApp, KakaoTalk, Skype, Viber). Telegram, docomo mail, and Inbox (Google, not yet registered) are the only major new apps, and really only Inbox is totally new.
How can I figure out which app (or setting) is causing the problem?
