[Samsung Galaxy S7 Edge Questions and Answers] trawick.dave@gmail.com:
My S7 Edge did the same thing recently....no fix but to send for replacement. I reset it to factory settings. I went in and did safe mode. I tried resetting it and not installing any google apps. Seems that my ROM had gotten corrupted or something for no reason there was definitely a hardware problem or corrupted data in the OS or ROM. Never could figure out what it was. I had insurance with Asurion and Verizon but because I had barely cracked the outer screen 3 months prior (digitizer and oled where fine....was just outter guarilla glass which people complain about due to having no tempered glass to fit it correctly. So i had gotten the skin type scratch protector and one 2 foot drop onto asphault not even 2 weeks after receiving the object...pebble cracked it on the edge. Three months the problem began with freezing amd resetting finally b4 giving up and making a claim. ASURION stuck me with the $200 deductible to get it replaced because they said the drop/crack caused the malfunction though it worked perfectly for the 3 months...even had full sensitivity at the cracked area. If you got insurance, i imagine you will have to replace it. I did ad i saw no other choice and it ticked me off them sticking me with the deductible of full 200. Leave the cracked screen on hell. Just fix what they didnt fix when they got it to refurbish it initially. Have gotten at least 5 poorly refurbed phones that didnt last a year that was passed off as GOOD AD NEW. Mine started lagging then it just got to were it wouldn't do anything but cycle reboots. It would freeze up and just reset and it would continually do that even with no google or verizon account setup or apps. Only installed the factory settings which included the preinstalled bloatware. Phone would boot, then reset, boot and would reset again...continuous loop until the battery would die.

I don't know if that's exactly what you're experiencing but mine was in a constant Loop of reset. T here was no water damaged or anything other than a drop months earlier, an update, and i had recently moved some apps to the ext Sd card (which that should have been resolved at factory reset) cause i removed the micro sd card incase it was conflicting in someway from priorly having apps installed onto it.. the only thing I can figure is it had the 7.0 nougat update when it began doing this. Hope that helps you out. Sorry for the run-on sentences. I tried clearing up my grammar and punctuation...at least look a bit edumacated.? I had been talk texting.

Currently, I'm with the S8 now. I haven't had any problems so far. Dont like the default samsung voice input that it resets to constantly. But i am sure the S8 has more support for the new OS THAN DID s7. Phone companies are notorious to slack on support for models even 1 year old. Minimal support at best. You might get 2 Android OS updates. Not likely though. Pushing the new big thing each year and forget about the loyal customers that have chosen to spend out money with said co. rather than their rival. After the N7 hand grenades. Time that Samsung start supporting their phones updates a bit better. I'm really of the opinion that sufficient testing and support wasnt given towards the s7 the 7.0 OS. New OS updates Always buggie when first released. I hadn't heard any other people having the same problems as we did but i havent looked. Verizon claims no issues from the update. I question all retailers truthfulness on such issues. It a business and i see hoe much they mark up their retail products. 5 time the cost of internet prices many times.

Do report back pleas e. Sorry so winded....wanted to give all my thoughts and details of my exact experience. Hope you can fix it cheaper than i did. The s8 is sure to have more samsung support for a longer time. Nag them if you are settling with insurance. They can give you a new phone vs. Refurbed if they want to make u satisfied.

Good luck brother. Many blessings.
