Hello,
I have an I9195 S4 mini that's relatively new, about 3-4 months, but the problem has been there from the beginning. I have sent it to repairs under warranty 3 times now but nothing's changed, so I decided it was time I took the things into my own hands.

The phone reboots while using WhatsApp. I have tried uninstalling all the other apps and nothing changed. So, only when using WhatsApp it restarts, but that's a huge problem for me since i want to use WhatsApp regularly, all day long sometimes.

What's there to do? Flashing a custom ROM?

Thanks in advance.

Hi,
I have a Moto G XT1032 (2013, 1st gen) with Lollipop 5.0.2

Stock Firmware: 220.27.1.falcon_umts.Retail.en.GB

On Sunday the phone began suddenly rebooting itself (it did so almost constantly at times). Sometimes I was able to get past the boot animation (which itself "lagged" on some of the boots/reboots) and be able to navigate menus or apps for 30 seconds and then another reboot would occur.
I decided to do factory reset (from the phones menu, one time I was able to navigate there without the device rebooting). Once I set up the phone, a few moments later (before the apps I had previously would download from my accounts synch) it began rebooting again... I gave up hope until the next day.

I followed to clear cache and Wipe data through the phone's stock recovery. Once I set it up, it began working fairly better. But the "hangs" and "lags" during normal operation were still occurring. The phone now rebooted rarely, but it still happened.

Yesterday and today the phone seems to be working better, and suffered no reboots, but for some reason I wake up and my phone is turned off... When turning it on again the battery was half-full.

I would like to know if this could be a hardware or software issue. In case of the former, I will have a bad time (money wise). In case of the latter, what should I do? Reflash stock firmware? Or what other thing would you recommend?

Thanks in advance.

Hi,

I am using Mi 3. There was a power button issue with my phone so I sent it to a service center. When I got my phone back, I noticed that whenever I lock my phone, it reboots in about 15-20 seconds. However, it doesn't reboot while using the phone. I updated it to MIUI 6 and the problem is still there. Can anybody please help me solve this? What could be causing this problem?
